Name
This is the Statement of Principles concerning incisional hernia (Reasonable Hypothesis) (No. 89 of 2025).
Commencement
This instrument commences on 24 November 2025.
Authority
This instrument is made under subsection 196B(2) of the Veterans' Entitlements Act 1986.
Repeal
The Statement of Principles concerning incisional hernia (Reasonable Hypothesis) (No. 73 of 2016) (Federal Register of Legislation No. F2016L01350) made under subsection 196B(2) of the VEA is repealed.
Application
This instrument applies to a claim to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 applies.
Definitions
The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
Kind of injury, disease or death to which this Statement of Principles relates
This Statement of Principles is about incisional hernia and death from incisional hernia.
Meaning of incisional hernia
For the purposes of this Statement of Principles, incisional hernia:
means a protrusion of intra-abdominal tissue through a fascial defect in the abdominal wall at the site of a previous surgical incision; and
includes incisional hernia that recurs following surgical repair of an incisional hernia.
While incisional hernia attracts ICD‑10‑AM code K43.0, K43.1 or K43.2, in applying this Statement of Principles the meaning of incisional hernia is that given in subsection (2).
For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.
Death from incisional hernia
For the purposes of this Statement of Principles, incisional hernia, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's incisional hernia.
Note: terminal event is defined in the Schedule 1 – Dictionary.
Basis for determining the factors
The Repatriation Medical Authority is of the view that there is sound medical-scientific evidence that indicates that incisional hernia and death from incisional hernia can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.
Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting incisional hernia or death from incisional hernia with the circumstances of a person's relevant service:
having worsening of Marfan syndrome before clinical onset;
having an incision for a surgical procedure which penetrates the abdominal wall before clinical onset at the incision site;
Note: Examples of surgical procedures which can penetrate the abdominal wall include, but are not limited to, laparoscopy, laparotomy, caesarean section, ileostomy, colostomy, prostatectomy, colectomy, and abdominal organ transplantation.
having a superficial infection within 30 days, at the incision site of a surgical procedure which penetrates the abdominal wall, in the 5 years before clinical onset at the incision site;
Note: superficial infection is defined in the Schedule 1 – Dictionary.
having a deep infection within 90 days, at the incision site of a surgical procedure which penetrates the abdominal wall, in the 5 years before clinical onset at the incision site;
Note: deep infection is defined in the Schedule 1 – Dictionary.
having wound dehiscence within 30 days, at the incision site of a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
Note: wound dehiscence is defined in the Schedule 1 - Dictionary.
taking sirolimus or everolimus for the purpose of transplant immunosuppression, within the 3 years following a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
taking corticosteroids other than inhaled or topical corticosteroids, for the purpose of immunosuppression, at the time of a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
taking systemic VEGF or VEGF-receptor inhibitors within the 3 months prior to, or 3 months following a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
Note: Examples of VEGF/VEGF-receptor inhibitors include, but are not limited to, bevacizumab, cabozantinib, regorafenib, lenvatinib, axitinib, pazopanib, and nintedanib.
having increased intra-abdominal pressure at the time of, or following a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
Note: Examples of conditions or settings which cause increased intra-abdominal pressure include, but are not limited to, ascites, constipation, coughing, heavy lifting, chronic ambulatory peritoneal dialysis, pregnancy, and straining.
having a Body Mass Index (BMI) of 25 or greater at the time of a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
Note: Body Mass Index (BMI) is calculated as W/H2 where:
W is the person's weight in kilograms; and
H is the person's height in metres.
having cirrhosis of the liver at the time of a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
having chronic obstructive pulmonary disease with chronic coughing at the time of a surgical procedure which penetrates the abdominal wall, at the time of clinical onset at the incision site;
smoking tobacco at the time of (or during healing of) a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
having severe malnutrition at the time of a surgical procedure which penetrates the abdominal wall, before clinical onset at the incision site;
inability to obtain appropriate clinical management for incisional hernia before clinical worsening.
Relationship to service
The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.
The factor set out in subsection 9(15) applies only to material contribution to, or aggravation of, incisional hernia where the person's incisional hernia was suffered or contracted before or during (but did not arise out of) the person's relevant service.
Factors referring to an injury or disease covered by another Statement of Principles
In this Statement of Principles:
if a factor referred to in section 9 applies in relation to a person; and
that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(2) 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.
