Statement of Principles concerning Meniere disease and Meniere syndrome (Balance of Probabilities) (No. 69 of 2024)

The instrument builds around a small set of tightly articulated legal‑medical concepts.

Definitions and scope: The SoP distinguishes between Meniere disease and Meniere syndrome. Meniere disease is defined as a primary (idiopathic) pathology affecting both the cochlea and vestibular apparatus on the same side with episodic attacks of vertigo, sensorineural hearing loss and/or tinnitus, all occurring on the same side; it “includes primary endolymphatic hydrops” and “excludes vestibular migraine” (s 7(2)(a)-(c)). Meniere syndrome is defined similarly but as a secondary pathology permanently affecting both the cochlea and the vestibular apparatus or the vestibulocochlear nerve on the same side; it “includes secondary endolymphatic hydrops” and “excludes vestibular migraine” (s 7(3)(a)-(c)). Both definitions note that the SoP can be invoked separately for each ear where bilateral involvement occurs (s 7(2) note; s 7(3) note).

Evidentiary premise: The RMA states its view that, on the available medical‑scientific evidence, a causal relationship to relevant service is more probable than not (s 8). The instrument operates as a prescriptive statement of the factors that, if established and related to relevant service, will support a finding of service connection on the balance of probabilities (title, s 8 and s 9). The SoP therefore functions as a legal‑medical filter: it specifies the kinds of antecedent events or conditions that can satisfy the causation element in claims.

Required factors: Section 9 lists four alternative factors; only one needs to be present to satisfy the “factors that must exist” threshold. They are: (1) a moderate to severe traumatic brain injury within three months before clinical onset or clinical worsening; (2) otosyphilis of the affected ear at time of clinical onset; (3) middle ear or inner ear surgery at least two months before clinical onset; and (4) inability to obtain appropriate clinical management for Meniere disease and Meniere syndrome before clinical worsening (s 9(1)-(4)). Each factor is expressed with temporal and clinical qualification.

Relationship to service and scope limits: Section 10(1) requires that any factor under s 9 “must be related to the relevant service rendered by the person.” Schedule 1 defines “relevant service” narrowly as eligible war service (other than operational service), defence service (other than hazardous service and British nuclear test defence service), or peacetime service under MRCA. Section 10(2) restricts the “clinical worsening” aspects of the factors to cases where the person’s Meniere disease/syndrome “was suffered or contracted before or during (but did not arise out of) the person’s relevant service,” and then only where the factor materially contributed to or aggravated the condition.

Death: The instrument explicitly includes death resulting from a terminal event or condition to which the person’s Meniere disease/syndrome contributed (s 7(6)); Schedule 1 lists examples of “terminal event” such as pneumonia and cardiac arrest. ICD‑10‑AM: the instrument notes the ICD‑10‑AM code H81.0 applies to these conditions but reiterates that the SoP’s own textual definitions govern (s 7(4)-(5)).

Cross‑SoP interaction: Section 11 provides that where a factor in s 9 refers to an injury or disease covered by another SoP, then the factors in that other SoP apply per its terms; this creates an explicit mechanism for inter‑SoP dependency.

These concepts together make the SoP a focused legal‑medical instrument that sets the permissible causal links between service and Meniere presentations for the statutory claims it governs.

Primary affected parties: The instrument applies to claimants in the VEA and MRCA systems whose claims involve Meniere disease or Meniere syndrome, and to the decision‑makers and medical advisers who assess those claims using statements under subsection 196B(3) of the VEA (s 3, s 5, s 8). The SoP’s reach is defined by the statutory claim pathways cited in s 5: “a claim to which section 120B of the VEA or section 339 of the MRCA applies.” The instrument itself does not name administering agencies or payment streams, but it functions as the RMA’s authoritative medical guidance to those statutory claim processes.

Claimant subgroups advantaged or constrained: The SoP creates a clear evidentiary pathway for claimants who can establish one of the listed factors and that the factor is related to “relevant service” as defined in Schedule 1. Those who can document a moderate to severe traumatic brain injury occurring within three months before clinical onset or worsening, documented otosyphilis at onset in the affected ear, previous middle or inner ear surgery meeting the two‑month timing qualification, or a demonstrable inability to obtain appropriate clinical management before clinical worsening, are within the scope of the SoP’s specified causal links and so have prescribed medical grounds for service connection (s 9).

Conversely, claimants who cannot establish any of the listed factors,or cannot show a relevant service relationship for a listed factor,are constrained by the instrument’s formulation. The SoP does not list alternative factors such as noise exposure, chemical exposure, or service types expressly excluded from the Schedule’s definition of relevant service. Therefore the group of claimants with Meniere presentations but without one of the enumerated factors may need to rely on other evidence or legal pathways outside this SoP’s prescriptive route.

Parties dealing with deaths: Relatives and estates pursuing death‑related claims are affected when the death results from a terminal event to which the decedent’s Meniere disease or syndrome “contributed” (s 7(6) and Schedule 1). The instrument requires a causal contribution to a terminal event, so estate claimants must marshal records showing contribution to listed terminal events, such as pneumonia or respiratory failure (Schedule 1).

Medical and record‑keeping actors: Treating practitioners, hospital record systems, and medico‑legal experts will be instrumental in proving the timing and nature of the factors in s 9. The instrument makes demands about temporal relationships (eg, “within the 3 months before clinical onset” for TBI, “at least 2 months before clinical onset” for surgery) and clinical diagnoses (eg, otosyphilis), which depend on contemporaneous medical documentation. The SoP’s reliance on clinical terms not fully defined in the instrument (for example “moderate to severe traumatic brain injury”, “clinical onset”, “clinical worsening”, “inability to obtain appropriate clinical management”) means that medical records and expert opinion will often be central to interpretation.

Other SoP users: Because s 11 requires that where s 9 refers to an injury/disease covered by another SoP, the factors in that other SoP apply, practitioners and decision‑makers handling multi‑condition claims must coordinate across SoPs. This affects medical assessors who must navigate potentially multiple, interlocking SoPs to determine causation.

In summary, the instrument directly affects claimants under the VEA/MRCA frameworks, their medical advisers, and the decision‑makers who apply SoPs to claims; it allocates evidentiary advantage to those who can document one of the specified factors and a relation to the defined categories of relevant service (s 9; Schedule 1).

This SoP itself does not create new statutory duties or entitlements; rather, it prescribes medical‑causal factors that decision‑makers should apply when assessing claims under specified provisions of the VEA and MRCA. The following are the principal operational duties and rights the text imposes or clarifies for those engaged in the claims process.

Duty to apply the SoP where relevant: The instrument is made under subsection 196B(3) of the VEA (s 3). It is therefore the RMA’s formal determination of the medical factors that “must exist” for service connection to be found on the balance of probabilities for the conditions in question (s 9). Decision‑makers determining claims that fall within s 5 (claims to which s 120B VEA or s 339 MRCA apply) are obliged to take the SoP into account as the authoritative medical statement when assessing causation, subject to the wider statutory and administrative framework those provisions provide.

Right to a causal pathway if factors established: Where at least one factor in s 9 is established and is related to the person’s relevant service (s 10(1)), the SoP provides the claimant with the prescribed causal pathway sufficient to support a finding of service connection on the balance of probabilities. The instrument’s title and s 8 emphasise the “balance of probabilities” standard: “On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that Meniere disease and Meniere syndrome and death from Meniere disease and Meniere syndrome can be related to relevant service” (s 8). This is a substantive declaration of the RMA’s view about causation thresholds for these conditions.

Duty to relate factors to relevant service: The SoP requires that any factor under s 9 be related to the person’s relevant service (s 10(1)). Schedule 1 defines relevant service narrowly (eligible war service other than operational service, defence service other than hazardous service and British nuclear test defence service, or peacetime service under the MRCA). The duty to show relation to one of these categories is a gating requirement for the SoP to operate.

Limit on clinical worsening application: Section 10(2) creates a particular rule for “clinical worsening” scenarios: the clinical worsening aspects of the s 9 factors apply only where the person’s Meniere disease/syndrome was suffered or contracted before or during (but did not arise out of) relevant service, and even then only where the factor materially contributed to or aggravated the condition. This confines one mode of application (worsening) to a subset of cases defined by when the condition was suffered and by the mechanism of contribution.

Cross‑SoP duty: If a factor in s 9 refers to an injury or disease covered by another SoP under s 196B(3), then the factors of that other SoP apply in accordance with its terms as in force from time to time (s 11). This imposes a duty on decision‑makers to consult and apply other SoPs when s 9 points to them.

Rights to rely on the SoP for death claims: Where death results from a terminal event or condition to which the Meniere disease/syndrome contributed, that death is within the SoP’s compass (s 7(6)); Schedule 1 gives concrete examples of terminal events. Claimants pursuing death‑related entitlements under the statutory schemes have the right to rely on this SoP to establish contribution to death, subject to the requirement that the contribution be shown.

Interaction with coding: The SoP references ICD‑10‑AM code H81.0 as the code that attaches to these conditions (s 7(4)-(5)), but it makes explicit that the textual definitions in subsections (2) and (3) govern the instrument’s meaning. Decision‑makers should therefore treat ICD coding as an administrative reference rather than the controlling definitional source.

Limits on the SoP’s scope and consequent duties: The instrument excludes vestibular migraine explicitly from both Meniere disease and Meniere syndrome (s 7(2)(c) and s 7(3)(c)), so parties have a duty to distinguish those diagnoses. The Schedule’s definition of relevant service also excludes certain service types, such as operational service and hazardous service in specified respects, which narrows the class of service connections that may be proven through this SoP.

In short, the SoP confers a right to a prescribed medical nexus where its factors are established and related to the defined relevant service categories, and it imposes a duty on decision‑makers to apply this RMA determination in assessing claims that fall within the identified statutory sections.

The instrument is an administrative medical determination, not a criminal statute or a sanctions instrument, and it does not itself establish penalties, fines, or criminal offences. The text contains no provisions that create civil penalties, administrative fines, or enforcement mechanisms tied directly to compliance with the SoP. Instead, the SoP functions as an authoritative medical framework for statutory claims under the Veterans' Entitlements Act 1986 and the Military Rehabilitation and Compensation Act 2004 (see s 3 and s 5). Enforcement in the practical sense occurs through its application (or non‑application) within those claims processes.

Adverse decisions and review: While the instrument does not set out appeal or review procedures, its determinations will be relied upon by decision‑makers when accepting or rejecting claims that fall within s 5. Any consequences for claimants arise through the outcome of a claim determination using the SoP (for example acceptance or rejection of an entitlement claim). Those consequences,payments, medical treatment entitlements, or denial of benefits,flow from the statutory frameworks referenced in s 5 rather than from the SoP itself. The instrument does not specify the review pathways (such as reconsideration or merits review) or time limits within which an affected person might challenge a decision applying the SoP; those procedural aspects are governed by the VEA and MRCA and their administrative regimes, not by this SoP text.

Operational compliance: For medical assessors and decision‑makers, “enforcement” consists of the requirement to use the SoP as the RMA’s statement of medical factors where relevant. The SoP will be an evidentiary rule for establishing causation on the balance of probabilities (s 8). Failure by a decision‑maker to apply the SoP where it is relevant could be a ground for administrative challenge within the VEA/MRCA review processes, but the instrument itself does not detail procedural remedies or sanctions.

Data and record requirements implicit in enforcement: Practical enforcement of the SoP’s standards depends on available medical records, diagnostic reports, surgical histories, and documentation showing the timing and relationship to relevant service. The SoP’s factors rely heavily on temporal and diagnostic facts (for example, the “within the 3 months before clinical onset” window for TBI in s 9(1)); thus the robustness of claim outcomes will depend on how thoroughly records are gathered and assessed.

In sum, the SoP does not create penalties; its “enforcement” is functional and embedded within the statutory claims machinery where its factors will be applied to accept or reject claims. Any legal consequences or recourse arise from that broader statutory and administrative architecture rather than from the SoP text itself.

This instrument is expressly made under subsection 196B(3) of the Veterans' Entitlements Act 1986 (s 3) and is intended to be applied within the claims frameworks set out in the VEA and the Military Rehabilitation and Compensation Act 2004. The text itself cross‑references those statutes rather than creating standalone legal obligations. Section 5 specifies the claims context: the SoP “applies to a claim to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 applies.” Users must therefore deploy this SoP within the procedural and substantive rules of those statutes (s 5).

Inter‑SoP linkage: Section 11 creates a direct interaction mechanism between this SoP and other SoPs made under subsection 196B(3) of the VEA. If a factor in s 9 “refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(3) of the VEA,” then “the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.” That makes the medical causation rules modular and interdependent: a factor here may import the detailed causal framework of another SoP, and decision‑makers must therefore consult and apply the relevant other SoP(s) in their existing form.

ICD coding and external standards: The SoP references ICD‑10‑AM coding (s 7(4)-(5)) and specifies the edition and effective date (Tenth Edition, effective date 1 July 2017). The reference to an external classification standard is administrative and clarifies the code H81.0’s associative value for Meniere disease/syndrome, but the SoP makes clear that the substantive meaning for applying the instrument is the textual definitions in subsections 7(2)-(3). In practice, this means ICD coding may be used to identify cases but cannot supplant the SoP’s definitions.

Relationship to statutory definitions of relevant service: Schedule 1 defines “relevant service” for the purposes of the instrument. It lists eligible war service (other than operational service), defence service (other than hazardous service and British nuclear test defence service) under the VEA, and peacetime service under MRCA. Those statutory concepts are themselves defined within the VEA and MRCA; the SoP imports them and therefore interacts with those statutes’ definitions and exclusions (s 5; Schedule 1). Any conflict or uncertainty about whether a person’s service fits within the Schedule’s wording will require reference to the VEA/MRCA statutory texts and their administrative interpretations.

Claims that arise from other statutory bases: The instrument does not state that it displaces or excludes other legal bases for establishing causation. It is a tool used in specified claim pathways. Because s 11 allows factors deriving from other SoPs to be applied, the instrument is explicitly designed to work within an integrated SoP system rather than in isolation. Where a claimant seeks to establish service connection by other legal means outside these SoP mechanisms, the SoP does not purport to govern those other routes; the instrument simply provides the RMA’s medical position for the statutory pathways identified.

Death and terminal events: The SoP’s inclusion of death and its definition of “terminal event” in Schedule 1 means the instrument interfaces with statutory death‑related entitlement provisions in the VEA and MRCA claims regimes. How an administrative decision treats causation for a death will therefore be shaped by this SoP’s requirement that the Meniere disease/syndrome “contributed to” a terminal event (s 7(6)).

Repetition, replacement and temporal effect: The instrument repeals an earlier SoP (No. 109 of 2015) by operation of s 4. This implies that the new SoP will be the operative RMA medical statement for these conditions from its commencement date; decision‑makers should apply this SoP rather than the repealed 2015 text for claims within its temporal and statutory scope.

In summary, the SoP operates as a medical‑causal rule within the VEA/MRCA statutory architecture, imports definitions from those statutes (notably “relevant service”), references but does not defer to ICD‑10‑AM coding, and explicitly requires cross‑consultation where other SoPs are implicated (s 11). Any legal effects on claims are realised through those statutes’ decision and review processes.

The instrument records a narrow but concrete amendment history. It is identified as No. 69 of 2024 and dated 20 August 2024 (cover text and s 1). Its commencement date is 24 September 2024 (s 2). Section 4 expressly repeals the earlier Statement of Principles concerning Meniere's disease No. 109 of 2015 (Federal Register of Legislation No. F2015L01329), which was also made under subsection 196B(3) of the VEA. The text therefore documents a single, explicit act of replacement: the 2024 SoP supersedes the 2015 SoP as the operative RMA determination for these conditions from the stated commencement date.

There are no other amendments recorded within the instrument itself. The instrument does not set out transitional provisions or savings clauses that preserve decisions taken under the repealed 2015 SoP, nor does it specify retroactivity or temporal limits for its application beyond the commencement date and the statutory scope identified in s 5. Decision‑makers and practitioners should therefore treat the 2015 SoP as repealed and the 2024 SoP as the active instrument from 24 September 2024 onwards (s 2 and s 4).

The instrument also incorporates an explicit referencing practice to other SoPs “as in force from time to time” (s 11). That language ensures that where s 9 refers to an injury or disease covered by another SoP, the applicable factors in that other SoP will be applied in their current form. This means that changes to other SoPs in the future will automatically be incorporated into the operation of this SoP where cross‑references arise.

No amendment schedule, sunset, or review timetable is set out in the instrument. The RMA’s authority to make Statements of Principles is statutory under subsection 196B(3) of the VEA (s 3), and amendments to this SoP would have to be made by subsequent RMA determinations and recorded in like fashion. The instrument does not itself specify who may amend it, the process for amendment, or any consultation requirements for future changes; any such processes would be governed by the RMA’s enabling statute and administrative practice, not by provisions within this text.

In short, the amendment history in the instrument is limited to the 2024 replacement and repeal of the 2015 SoP, effective from the stated commencement date; further amendment activity is not recorded in the text and would occur by subsequent RMA determinations.

The instrument itself does not record or cite any litigation, judicial decisions, or case law. It contains no references to court rulings, tribunals, or precedential decisions concerning the interpretation or application of the SoP. Accordingly, there is no litigation history supplied within the text that can be cited.

That absence has practical implications for users. Because the SoP is a medical determination of factors to be applied on the balance of probabilities, disputes about its application will arise in the context of claim determinations under the VEA and MRCA. Potential points of dispute that could lead to litigation or merits review are discernible from the instrument’s content even though no cases are cited:

• Ambiguities in clinical terms: The SoP uses terms such as “moderate to severe traumatic brain injury,” “clinical onset,” “clinical worsening,” and “inability to obtain appropriate clinical management” without providing detailed statutory definitions within the text. These terms are likely focal points for differing expert opinions and administrative decisions and thus could be the subject of reconsideration or appeals in the VEA/MRCA frameworks.

• Temporal qualifications: Section 9 sets specific windows for temporality, for example TBI “within the 3 months before clinical onset or clinical worsening” and surgery “at least 2 months before clinical onset” (s 9(1) and s 9(3)). Disputes over when clinical onset or worsening occurred, and how to measure those windows, may generate factual contest in claims decisions.

• Relation to relevant service: Section 10(1) requires that any factor be related to the person’s relevant service as defined in Schedule 1. Because “relevant service” is narrowly defined and excludes certain service types, claims might be contested on whether a veteran’s service falls within the Schedule’s categories.

• Inter‑SoP interactions: Section 11’s cross‑reference to other SoPs creates dependency on the content and application of other RMA determinations. Litigation could arise from disagreements about which SoP applies or how the factors in another SoP should be interpreted and applied in a particular claim.

• Death and contribution: For death claims, s 7(6) requires that the Meniere disease/syndrome “contributed to” a terminal event. Interpretation of “contributed to” and proof that contribution may be contested in adjudicative processes.

Because the instrument is silent on procedural review pathways (these are set by the VEA and MRCA), any litigation or tribunal history that eventually develops will be found in the decisions made under those statutes and their review mechanisms rather than within the SoP text. Users should therefore look to the VEA/MRCA decision records, merits review outcomes, and judicial review cases addressing the application of RMA SoPs for any litigated interpretation of provisions similar to those in this SoP.

For the present instrument, the text provides no litigation precedent to cite; practitioners must anticipate that interpretive issues noted above are where future disputes are most likely to arise and plan evidence and arguments accordingly.

Practitioners, claimants, and medical advisers should note several traps and potential pitfalls inherent in the instrument’s wording and structure; each “gotcha” below is grounded in the text and refers to the specific provisions.

1. Narrow notion of relevant service: Schedule 1 defines “relevant service” as eligible war service (other than operational service), defence service (other than hazardous service and British nuclear test defence service) under the VEA, or peacetime service under the MRCA. That wording excludes operational service and hazardous service (as specified), which is a blunt filter. A claimant whose exposure or injury occurred during excluded service types will not be able to rely on the SoP’s prescriptive factors absent other legal bases (Schedule 1). Practitioners must verify service categorisation carefully.

2. Clinical worsening rule is constrained: Section 10(2) states that the “clinical worsening aspects of factors set out in section 9” apply only to material contribution or aggravation where the Meniere disease/syndrome was suffered or contracted before or during (but did not arise out of) the relevant service. If a person’s Meniere disease actually arose out of the relevant service, s 10(2) appears to exclude application of the clinical worsening pathway,this is a technical but potentially decisive limitation for claims that rely on post‑service worsening versus service origin. Care is required to establish when the condition was first suffered or contracted.

3. Vague clinical terminology: Critical phrases are not defined in the instrument. Examples include “moderate to severe traumatic brain injury,” “clinical onset,” “clinical worsening,” and “inability to obtain appropriate clinical management.” The absence of internal definitions means these terms will be open to medical and legal argument, potentially increasing evidentiary disputes and reliance on expert opinion. This is particularly salient for s 9(1) and s 9(4).

4. Tight temporal windows: The SoP sets particular time limits: TBI must be within three months before onset/worsening (s 9(1)); surgery must be at least two months before onset (s 9(3)). A claimant with an otherwise plausible causal narrative but with events slightly outside these windows risks falling outside the SoP’s factors. Practitioners must carefully document dates and establish precise onset/worsening timing.

5. Exclusion of vestibular migraine: Both definitions explicitly exclude vestibular migraine (s 7(2)(c) and s 7(3)(c)). A claimant whose symptom complex is ultimately classified as vestibular migraine will not be covered by this SoP even if the symptomatic elements resemble Meniere presentations. Diagnostic clarity before claiming is therefore important.

6. Requirements for death claims: The instrument includes death caused by Meniere disease/syndrome only where the disease “contributed to” a terminal event (s 7(6)). The Schedule’s list of terminal events is illustrative but not exhaustive, and the causal link required is contributory, which can be a high evidentiary hurdle particularly where comorbidities exist.

7. Cross‑SoP complexity: Section 11’s direction to apply other SoPs where s 9 refers to an injury or disease covered by another SoP can complicate claims. If s 9 refers to, for example, traumatic brain injury, the TBI SoP’s factors and definitions will import into the analysis. Practitioners must cross‑check applicable SoPs and their current versions, and ensure harmonised evidence.

8. Repeal of 2015 SoP: The 2015 SoP was repealed (s 4). Cases or arguments that relied on that former text must be reassessed in light of the 2024 SoP; historical reliance on older criteria could mislead if not reconciled with the new instrument.

9. ICD‑10‑AM citation does not control: The instrument notes the ICD‑10‑AM H81.0 code applies (s 7(4)-(5)), but it emphasises the textual definitions govern. Reliance on code alone without addressing the SoP’s definitional elements may be insufficient.

10. Burden of proof and documentary needs: The SoP presumes the balance of probabilities standard (title and s 8). However, establishing a factor’s relation to relevant service will typically require contemporaneous medical records, diagnostic reports, surgical notes, and service records. The instrument itself does not prescribe what documents suffice, making pre‑emptive collation of comprehensive records essential.

Each of these “gotchas” follows from the instrument’s wording. Practitioners should plan evidence collection and argumentation to address these specific constraints rather than relying on general medical narratives.

Compliance here means preparing and presenting evidence so that a decision‑maker assessing a claim under the VEA or MRCA (the claims identified in s 5) can properly apply the RMA’s SoP. The SoP sets a discrete evidentiary map: one of the factors in s 9 must be established and shown to be related to the person’s relevant service as defined in Schedule 1. The following are source‑grounded, practical steps to align case preparation with the instrument’s requirements.

1. Ascertain whether the claim falls within the SoP’s statutory scope. Verify that the claim is one “to which section 120B of the VEA or section 339 of the MRCA applies” (s 5). Confirm the service classification against Schedule 1’s definition of “relevant service” (eligible war service other than operational service; defence service other than hazardous service and British nuclear test defence service under the VEA; or peacetime service under MRCA). If the claimant’s service falls outside these categories, this SoP’s factors will not automatically apply.

2. Identify which s 9 factor is being relied upon. Only one of the listed factors needs to be established (s 9). Choose the factor for which the strongest contemporaneous and expert evidence exists: (a) moderate to severe TBI within three months before clinical onset or worsening (s 9(1)); (b) otosyphilis of the affected ear at clinical onset (s 9(2)); (c) middle ear or inner ear surgery at least two months before clinical onset (s 9(3)); or (d) inability to obtain appropriate clinical management before clinical worsening (s 9(4)).

3. Document temporality precisely. For s 9(1) and s 9(3) the instrument specifies temporal windows. Establish precise dates for traumatic brain injury, onset of Meniere symptoms or clinical worsening, and any ear surgery. Where onset/worsening dates are contested, obtain contemporaneous clinical notes, emergency department records, audiology reports, and practitioner statements to narrow the onset window.

4. Establish diagnosis and affected side(s). The definitions require pathology affecting both cochlea and vestibular apparatus on the same side with manifestations of vertigo, sensorineural hearing loss and/or tinnitus (s 7(2)(a); s 7(3)(a)). Provide audiometry, vestibular testing, imaging where relevant, and treating clinician statements confirming the affected side. If bilateral disease is claimed, note that the SoP may be invoked twice for bilateral involvement (s 7(2) note; s 7(3) note).

5. For otosyphilis (s 9(2)), secure diagnostic documentation that otosyphilis of the affected ear was present at the time of clinical onset. This will typically require serological testing records, specialist infectious diseases or ENT notes, and contemporaneous clinician documentation tying the otosyphilis to the ear involved.

6. For surgical antecedents (s 9(3)), provide operative reports, discharge summaries, surgical dates, and any post‑operative notes. Demonstrate that surgery predates clinical onset by at least two months, per the instrument.

7. For the “inability to obtain appropriate clinical management” factor (s 9(4)), compile evidence demonstrating lack of access or failure to obtain appropriate management prior to clinical worsening. This will likely include referral records, documented waiting times, correspondence showing access barriers, notes of unsuccessful attempts to obtain care, and clinical evidence linking the lack of treatment to subsequent worsening. Given the instrument’s lack of an internal definition, expert medical opinion linking inadequate access to material worsening will be necessary.

8. Relate the factor to relevant service. Section 10(1) requires that the existence of any s 9 factor “must be related to the relevant service rendered by the person.” Prepare service records, duty logs, incident reports, and nexus statements that connect the factor (for example a TBI event, an infection, or a surgical procedure necessitated by service circumstances) to the specified type of relevant service in Schedule 1.

9. For clinical worsening scenarios, ensure the condition was suffered or contracted before or during (but did not arise out of) relevant service, if relying on s 10(2). If the Meniere disease/syndrome arose out of service, note that s 10(2) limits the application of the clinical worsening aspects. Craft evidence and submissions to align with that limitation.

10. For death claims, produce the death certificate, terminal event documentation, hospital records around the terminal event, and clinician statements establishing that the Meniere disease/syndrome contributed to the terminal event (s 7(6) and Schedule 1). Where comorbidities exist, expert opinion should address the relative contribution.

11. Cross‑check other SoPs where relevant. If s 9 relies on an injury or disease covered by another SoP, apply the factors in that other SoP in force at the time (s 11). Gather evidence required by the other SoP and prepare cross‑references in submissions.

12. Anticipate definitional disputes and provide expert evidence. Because the instrument lacks in‑text definitions for key clinical phrases, include treating clinician and independent specialist reports that interpret those phrases in the claimant’s context. For example, for “moderate to severe TBI,” an expert can explain how the claimant’s TBI meets the requisite severity threshold.

13. Use ICD‑10‑AM coding prudently. The SoP notes that H81.0 is the ICD code associated with these conditions (s 7(4)-(5)), but the textual definitions govern. Use coding as an adjunct to clinical evidence rather than a substitute.

14. Preserve records and contemporaneous statements. The SoP’s reliance on temporality and clinical facts means that delays in assembling records can be costly. Obtain hospital records, GP notes, audiology and vestibular test results, and service documentation early.

By following these steps grounded in the instrument’s text,verifying relevant service, selecting and proving a s 9 factor with temporal and clinical precision, and ensuring a demonstrated link between the factor and the relevant service,practitioners will align case preparation with the RMA’s SoP requirements.
