Digestive system injury claim
Digestive injury after a motor accident
Blunt abdominal force can perforate bowel, damage mesentery or pancreas, cause a traumatic hernia or require resection and a stoma. Permanent impairment is not based on abdominal pain or surgery alone. AMA4 Chapter 10 assesses the affected digestive function, including objective disease, symptoms, treatment, dietary restriction, weight or nutrition and the specific structural outcome.
Accident mechanism and diagnosis
How can this injury happen in a motor accident?
Seatbelt or handlebar compression
Focal force can injure stomach, duodenum, small bowel, mesentery, colon or pancreas.
Crush or penetrating injury
High-energy trauma can perforate bowel, contaminate the abdomen and require resection, diversion or repeated surgery.
Treatment-related digestive disease
Long-term anti-inflammatory or opiate medication started after the crash can cause specific digestive conditions addressed by clauses 6.247-6.248.
The injuries that may actually occur
- oesophageal, stomach or duodenal injury
- small-bowel or colonic perforation and resection
- pancreatic injury with exocrine insufficiency
- anal or rectal injury
- permanent surgically created stoma or enterocutaneous fistula
- traumatic or incisional abdominal-wall hernia
Symptoms and functional effects to document
- vomiting, reflux or upper digestive intolerance
- diarrhoea, urgency, constipation or altered bowel frequency
- dietary restriction and weight or nutritional change
- stoma or fistula care needs
- hernia protrusion and lifting or activity restriction
Urgent health warning
Severe abdominal pain, persistent vomiting, fever, rigid abdomen, bleeding, bowel obstruction symptoms or a painful irreducible hernia requires urgent care.
Medical evidence
What tests and findings matter?
The exact digestive segment and lasting pathology should be identified. Diet, weight and bowel symptoms need corroboration from treatment, investigations and clinical examination rather than being converted directly into a percentage.
| Test or record | What it can establish | What it cannot establish alone |
|---|---|---|
| Operative and pathology records | Identify perforation, resection length, anastomosis, stoma, fistula, pancreatic loss and complications. | The operation itself does not select an impairment class. |
| Endoscopy and contrast or cross-sectional imaging | May show ulceration, stricture, fistula, obstruction, hernia or structural disease. | A structural finding must match the permanent clinical and functional result. |
| Weight and nutritional testing | Documents sustained weight loss, malabsorption, deficiencies and treatment needs. | A short acute weight change during admission is not necessarily permanent. |
| Diet, bowel and stoma records | Show restriction, frequency, continence, appliance needs and effect on ordinary activity. | A claimant description without clinical corroboration does not set the Chapter 10 class. |
A separate legal classification
Threshold injury is not the same as WPI
A perforation, resection, fistula, stoma or traumatic hernia may be more than a soft tissue injury. Digestive symptoms without a supported accident-caused pathology may not establish a non-threshold injury. WPI is separately assessed under Part 6.
A non-threshold classification does not set a WPI percentage. Conversely, a low or zero WPI assessment does not necessarily decide the threshold-injury classification. Physical and psychiatric WPI are assessed separately and cannot be combined to determine whether impairment is greater than 10%.
Motor Accident Guidelines Part 6
How is permanent impairment assessed?
Clauses 6.244-6.249 adopt AMA4 Chapter 10 Tables 2-7: upper digestive tract, colon/rectum, anus, surgically created stomas, liver/biliary tract and abdominal-wall hernias. The applicable table depends on the anatomical result. Clause 6.246 corrects the Table 2 class 2 weight wording, and clause 6.249 modifies the criteria required for the hernia classes.
| Assessment issue | CTP method | Important limit |
|---|---|---|
| Upper digestive tract or pancreas | Use AMA4 Chapter 10 Table 2 with the clause 6.246 wording correction. | Symptoms, treatment and nutritional effect must fit the complete class criteria. |
| Colon, rectum, anus, stoma or liver | Use the applicable Chapter 10 Table 3-6. | A stoma, fistula or organ resection is assessed by its specific consequence rather than a generic surgery value. |
| Abdominal-wall hernia | Use Chapter 10 Table 7 as modified by clause 6.249. | Classes 1 and 2 require the first criterion plus the second or third; class 3 requires all three. |
Verified Guidelines example or rule
Clause 6.248 states that constipation alone results in 0% WPI. It also addresses colonic or rectal disease caused by accident-related opiate medication. Clause 6.247 separately addresses upper digestive disease caused by ongoing anti-inflammatory medication.
What may result in 0% or no assessable WPI?
- constipation alone under clause 6.248
- resolved bowel or stomach injury with no permanent digestive dysfunction
- temporary post-operative dietary restriction or weight loss
- a reducible or repaired abdominal-wall defect that does not satisfy the applicable impairment criteria
What may support a higher assessment if verified?
- permanent dietary restriction and objective upper digestive disease
- sustained accident-related weight or nutritional loss
- permanent stoma, fistula or substantial bowel resection with functional consequences
- a hernia satisfying the required Table 7 structural and activity criteria
Combination and overlap rules
- Use the specific table for each distinct digestive segment and combine only as AMA4 and Part 6 permit.
- Endocrine pancreatic impairment is assessed under Chapter 12 and combined only if distinct from exocrine digestive loss.
- Pain is included in the digestive method and has no separate Chapter 15 allowance.
What does not establish impairment by itself?
- abdominal pain alone
- constipation alone
- the fact bowel surgery occurred
- one scan finding without permanent symptoms and function
Crash-specific examples
Temporary ileostomy reversed successfully
The acute treatment may be extensive, but the permanent assessment considers the post-reversal digestive function, not the temporary stoma alone.
Pancreatic resection with malabsorption
Chapter 10 addresses exocrine digestive consequences such as malabsorption and weight effect; any endocrine diabetes consequence uses Chapter 12 separately.

What the assessor checks
- the affected digestive segment
- objective permanent pathology
- diet, weight, treatment and function
- the clause 6.246-6.249 modifications
What does not establish the result by itself
- pain
- constipation alone
- surgery alone
- temporary diet or weight change

Frequently asked questions
- Which AMA4 tables apply to digestive injury?
- Chapter 10 Tables 2-7 cover different segments and outcomes, including upper digestive tract, colon/rectum, anus, stomas, liver/biliary tract and hernia.
- Does constipation receive WPI?
- Clause 6.248 states that constipation alone results in 0% WPI.
- Does a temporary stoma create permanent WPI?
- Not automatically. Assessment reflects the permanent result at the time of assessment.
- Can medication-caused digestive disease be assessed?
- Clauses 6.247-6.248 address specified disease caused by ongoing anti-inflammatory or opiate medication begun after the injury.
- Does bowel surgery set a fixed percentage?
- No. The permanent digestive function and applicable table criteria determine the assessment.
