Negotiated agreements displace the Schedules entirely: Rule 5(2) provides that where an insurer has a negotiated agreement with a hospital, the minimum benefit is the amount in the agreement, not the Schedule amount. This means the Schedules are only the fallback for non-contracted hospitals. For hospitals with agreements, the minimum benefit is entirely a contractual matter.
The "comparable hospital" calculation is complex: For Schedule 5 (second-tier eligible hospitals), the minimum benefit is calculated by reference to the insurer's negotiated agreements with comparable hospitals in the same state. As the Federal Court found in Rehabilitation Medicine Australia Pty Ltd v NIB Health Funds Ltd [2020] FCA 1761 (at [28]-[41]), the correct methodology for identifying comparable hospitals and the applicable episode involves a sequential multi-step process that requires careful interpretation of clause 3 of Schedule 5. The court held that where there are fewer than five comparable hospitals, the insurer's agreements with all classes of private hospital in the state must be used.
Co-payments and excesses reduce, but cannot eliminate, the minimum benefit: Rules 4(2) and 5(3) allow the minimum benefit to be reduced by the co-payment or excess in the insured person's policy. However, the minimum benefit is a genuine floor: the combination of the benefit and the patient's co-payment must be sufficient to cover the hospital's charges (subject to rule 6).
Type A, B, C classification is procedure-specific: The minimum benefit applicable to a particular episode depends on how the clinical procedure is classified in the relevant Schedule. A procedure not listed as a Type A procedure will attract a lower minimum benefit unless the insurer has certified it. Practitioners advising hospitals or patients on minimum benefit entitlements need to check the procedure classification for each episode.
