Use Code

What ICD-10 codes are used for NASH?

Nonalcoholic steatohepatitis (NASH) is a form of chronic liver disease characterized by fat accumulation in the liver and inflammation. Here are commonly used ICD-10-CM codes for NASH, along with brief clinical descriptions:

K75.81: Nonalcoholic steatohepatitis (NASH)

This is the only specific ICD code for cases of NASH, which is characterized by liver inflammation and fat accumulation due to causes other than alcohol.

Other relevant codes

Beyond what we know about NASH, it is important to know more, consider, or rule out other associated codes.

K76.0: Fatty (change of) liver, not elsewhere classified

Applied when fatty liver disease, including NASH, is diagnosed but without further specification.

K75.89: Other specified inflammatory liver diseases

Utilized for other specific inflammatory liver diseases, which may include NASH in some cases.

E83.29: Other hyperalimentation

Used when NASH is associated with overnutrition or other metabolic conditions.

E78.5: Hyperlipidemia, unspecified

Applied when NASH is associated with high levels of lipids (fats) in the blood, which is common in these patients.

K76.89: Other specified diseases of the liver

Utilized when NASH is diagnosed but is not classified under a more specific code.

E61.5: Hyperhomocysteinemia due to unspecified B group vitamin deficiency: 

Used for NASH cases associated with elevated homocysteine levels due to unspecified B vitamin deficiency.

E66.9: Obesity, unspecified

Applied for NASH cases associated with obesity, but without specifying the degree or type.

K76.9: Liver disease, unspecified

Utilized for cases where liver disease is diagnosed but the specific liver condition is unspecified.

K76.4 - Peliosis hepatis

Used when NASH is complicated by peliosis hepatis, a rare condition involving blood-filled cysts in the liver.

Which NASH ICD codes are billable?

The billable status of the mentioned ICD-10 codes for NASH varies

  • K75.81 - Nonalcoholic steatohepatitis (NASH): Yes, billable. Medical expenses related to NASH can be claimed.
  • K76.0 - Fatty (change of) liver, not elsewhere classified: Not typically billable on its own. Additional details are required for billing.
  • K75.89 - Other specified inflammatory liver diseases: Yes, billable. Costs associated with other specific inflammatory liver diseases, including NASH, can be reimbursed.
  • E83.29 - Other hyperalimentation: Not typically billable for NASH alone. It may be billable when associated with other conditions.
  • E78.5 - Hyperlipidemia, unspecified: Not typically billable for NASH alone. It may be billable when hyperlipidemia is a significant part of the diagnosis.
  • K76.89 - Other specified diseases of the liver: Yes, billable. Medical expenses for other specific liver diseases, including NASH, can be claimed.
  • E61.5 - Hyperhomocysteinemia due to unspecified B group vitamin deficiency: Not typically billable for NASH alone. It may be billable when associated with other conditions.
  • E66.9 - Obesity, unspecified: Not typically billable for NASH alone. It may be billable when obesity is a significant part of the diagnosis.
  • K76.9 - Liver disease, unspecified: Not typically billable for NASH alone. It may be billable when associated with other conditions.
  • K76.4 - Peliosis hepatis: Yes, billable. Medical expenses for NASH complicated by peliosis hepatis can be claimed.

Clinical information

  • Nonalcoholic steatohepatitis (NASH) is a type of nonalcoholic fatty liver disease (NAFLD) characterized by inflammation and damage.
  • NASH is often associated with metabolic conditions such as obesity, type 2 diabetes, and high cholesterol.
  • Diagnosis involves a combination of clinical evaluation, imaging (ultrasound, CT, MRI), and liver biopsy.
  • Similar to alcoholic liver disease, toxic liver disease, and other disorders such as chronic hepatitis, management strategies include lifestyle modifications, such as weight loss, dietary changes, and increased physical activity.
  • Medications may be considered to manage risk factors and comorbid conditions like diabetes.
  • Regular monitoring is essential to assess liver function and disease progression.
  • Progression of NASH can lead to cirrhosis and liver failure, making early diagnosis and intervention critical.
  • Healthcare practitioners should educate patients on adherence to treatment plans, lifestyle changes, and regular follow-up to manage NASH effectively.

Synonyms include

  • Nonalcoholic steatohepatitis
  • NASH liver disease
  • Fatty liver disease
  • Inflammatory liver disease
  • Liver inflammation
  • NASH ICD-10

Commonly asked questions

Common symptoms of NASH include fatigue, abdominal discomfort, and an enlarged liver. However, many individuals with NASH may not have noticeable symptoms until the disease progresses.

Treatment for NASH involves lifestyle changes such as weight loss, a healthy diet, exercise, and managing underlying conditions like diabetes and high cholesterol. In some cases, medications may be prescribed.

Yes, NASH can progress to cirrhosis, which is advanced liver scarring. Regular medical evaluation and lifestyle changes are crucial to prevent this progression.
