K70 Alcoholic liver disease

Name of the Condition

• Alcoholic Liver Disease
• ICD-10 Code: K70

Summary

Alcoholic liver disease is a spectrum of liver conditions caused by excessive alcohol consumption, ranging from fatty liver to inflammation (hepatitis) and scarring (cirrhosis). It represents the cumulative damage to the liver from chronic alcohol use.

Causes

Chronic and excessive alcohol intake is the primary cause. Alcohol’s toxic effects on liver cells lead to inflammation, fat accumulation, and eventual scarring, progressing through stages of liver disease.

Risk Factors

• Prolonged heavy alcohol consumption
• Genetic predisposition to alcohol-related liver damage
• Poor nutrition, which exacerbates liver stress
• Gender (women may be more susceptible at lower alcohol levels)
• Coexisting liver conditions (e.g., viral hepatitis)

Symptoms

• Fatigue and weakness
• Jaundice (yellowing of skin/eyes)
• Abdominal pain or swelling
• Loss of appetite and weight loss
• Nausea or vomiting
• Easy bruising or bleeding

Diagnosis

Blood tests assess liver function (e.g., enzymes, bilirubin). Imaging (ultrasound, CT) evaluates liver structure. A liver biopsy may confirm inflammation, fat, or scarring. Clinical history of alcohol use is critical.

Treatment Options

• Complete alcohol abstinence to halt progression
• Nutritional support and dietary modifications
• Medications to manage symptoms (e.g., inflammation, fluid retention)
• Management of complications (e.g., ascites, encephalopathy)
• Liver transplant evaluation for end-stage disease

Prognosis and Follow-Up

Prognosis depends on disease stage and abstinence adherence. Early intervention may reverse fatty liver or mild hepatitis, but advanced cirrhosis is often irreversible. Regular monitoring of liver function and alcohol use is essential.

Complications

• Liver failure
• Portal hypertension (increased blood pressure in liver vessels)
• Ascites (fluid buildup in abdomen)
• Hepatic encephalopathy (brain function decline)
• Increased risk of liver cancer

Lifestyle & Prevention

• Limit or avoid alcohol consumption
• Maintain a balanced diet rich in nutrients
• Avoid other liver toxins (e.g., certain medications)
• Vaccinations for hepatitis A/B to prevent additional liver stress

When to Seek Professional Help

Seek care for persistent symptoms (jaundice, abdominal pain, unexplained weight loss) or signs of liver failure (confusion, severe fatigue). Urgent evaluation is needed for sudden worsening of symptoms.

Tips for Medical Coders

Document the clinical stage (e.g., fatty liver, hepatitis, cirrhosis) and any complications (e.g., ascites, encephalopathy) to support code specificity. Ensure alcohol use history is clearly recorded, as it is central to diagnosis. Use additional codes for related conditions (e.g., malnutrition) if applicable.
