Diagnostic Code 7311 · 38 CFR §4.114
DC 7311 covers the long-term residual effects of a liver injury — typically from combat trauma (penetrating wounds, blast injuries), motor vehicle accidents, surgical complications, or other blunt or penetrating force to the upper right abdomen. Acute liver injuries are usually managed during the initial hospitalization with surgery, embolization, or supportive care; what DC 7311 rates are the consequences that persist after recovery: scar tissue affecting liver architecture, areas of necrosis, residual bile leak or fistula, and the functional impact on liver metabolism. The VA rates DC 7311 based on the residuals using whichever code captures the dominant impairment — chronic liver dysfunction tracks under the cirrhosis framework (DC 7312), recurrent biliary issues track under cholangitis or fistula codes, and significant scarring of the right upper quadrant may produce its own pain and adhesion symptoms. For veterans with severe injuries, the residuals can include portal hypertension, persistent elevation of liver enzymes, and limited capacity to metabolize medications and toxins.
| Rating | Criteria |
|---|---|
| 0% | Healed liver injury with no current symptoms, normal liver function tests, and no functional impairment. |
| 10% | Mild residuals — minor elevation in liver enzymes, occasional right-upper-quadrant discomfort, or imaging showing residual scarring without functional impact. |
| 30% | Moderate residuals — persistent symptoms (chronic right-upper-quadrant pain, fatigue, dietary intolerance), sustained mild-to-moderate liver enzyme elevation, or imaging showing significant scarring or volume loss; rate under DC 7312 (cirrhosis) if liver dysfunction is the dominant feature. |
| 60% | Severe residuals — substantial functional impairment, progressive liver dysfunction, recurrent biliary infections, or other manifestations rated at the 60% level under the appropriate underlying code (cirrhosis, hepatic encephalopathy, fistula). |
| 100% | Pronounced residuals at the 100% level under the underlying code — typically decompensated cirrhosis with ascites, variceal bleeding, encephalopathy, requirement for transplant evaluation, or other terminal liver dysfunction. |
The original trauma records — emergency department reports, operative notes from any laparotomy, CT or MRI imaging showing the injury — are foundational. Current imaging (CT, MRI, or ultrasound of the liver) documents the residual scarring, volume loss, or biliary tree disruption. Liver function tests (AST, ALT, alkaline phosphatase, bilirubin, albumin, INR) demonstrate ongoing functional impairment. A hepatology or general surgery consult characterizes the residuals and connects them to the original injury. Service treatment records establishing the in-service injury close the nexus. If subsequent complications (biliary stricture, abscess, fistula, portal hypertension) developed, the records of those workups support the higher rating tiers.
A truly healed liver injury with normal labs, normal imaging, and no functional impact typically rates at 0%. A 0% rating still preserves service connection, which matters: if complications develop years later (cirrhosis, biliary issues, hepatic decompensation), service connection is already established and the rating can be increased without re-fighting the original nexus. Keep the 0% rating on the record.
The principle is that the rater applies the code that produces the higher rating given the dominant impairment. If the residuals are mild scarring with mostly preserved liver function, DC 7311 typically applies. If the scarring has progressed to clinical cirrhosis with portal hypertension, ascites, or encephalopathy, DC 7312 takes over because its rating tiers go up to 100% for decompensated disease. The two codes are not stacked; one is chosen.
Yes — chronic liver scarring and inflammation are documented risk factors for hepatocellular carcinoma. A veteran with service-connected liver injury residuals who later develops liver cancer can pursue secondary service connection under DC 7343 (malignant neoplasms of the digestive system, exclusive of skin). The nexus opinion typically runs through the scarring as the predisposing condition.
