ICD-10 Code E78.79 – Other disorders of bile acid and cholesterol metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E78.79 – Other disorders of bile acid and cholesterol metabolism
What it is
This code identifies a disorder affecting bile acid or cholesterol metabolism that does not fit a more specific category. Use it when documentation names an unusual or unspecified metabolic abnormality in this pathway.
Clinical signs
Clinical features vary; refer to documentation. Findings may include abnormal lipid or bile acid metabolism noted in the record, but the exact presentation depends on the underlying disorder.
When to use this code
Use E78.79 when the clinician documents another disorder of bile acid and cholesterol metabolism and no more specific ICD-10-CM code applies. It is appropriate for charted metabolic abnormalities involving these pathways when the diagnosis is clearly stated. Check documentation if the record is vague or only mentions abnormal labs.
Do not use for
Do not use this code for routine hyperlipidemia, pure hypercholesterolemia, or other better-defined lipid disorders. If the condition is specified elsewhere in the chart, choose the more exact code.
Coding tip
Query for specificity when the note only says “lipid disorder” or “cholesterol issue.”
