Nonalcoholic steatohepatitis (NASH)
ICD-10 K75.81 is a billable code used to indicate a diagnosis of nonalcoholic steatohepatitis (nash).
Nonalcoholic steatohepatitis (NASH) is a progressive liver disease characterized by the accumulation of fat in the liver, inflammation, and liver cell damage, occurring in individuals who consume little to no alcohol. Clinically, NASH may present with fatigue, malaise, and right upper quadrant discomfort, although many patients remain asymptomatic. The liver, primarily involved in metabolism and detoxification, can develop fibrosis and eventually progress to cirrhosis or hepatocellular carcinoma if left untreated. The disease is often associated with metabolic syndrome, including obesity, type 2 diabetes, and dyslipidemia. Diagnosis typically involves imaging studies, such as ultrasound or MRI, and liver biopsy to assess the degree of steatosis and inflammation. Laboratory tests may reveal elevated liver enzymes (ALT and AST) and other markers of liver dysfunction. Early detection and management are crucial to prevent disease progression and associated complications.

K75.81 specifically covers nonalcoholic steatohepatitis, which is characterized by liver inflammation and damage due to fat accumulation, distinct from alcoholic liver disease and other liver conditions.
K75.81 should be used when there is clear evidence of liver inflammation and damage associated with fat accumulation in patients who do not consume significant amounts of alcohol, differentiating it from K75.80.
Documentation should include clinical findings, imaging results, liver function tests, and any biopsy results that confirm the diagnosis of NASH, along with a thorough patient history.
