Other disorders of bile acid and cholesterol metabolism

This code signifies a range of metabolic disturbances involving bile acids and cholesterol that are not specifically classified elsewhere. It encompasses conditions where the body's synthesis, transport, or breakdown of these lipids is impaired, leading to various clinical manifestations. These disorders can affect liver function, digestion, and overall lipid homeostasis.

Use this code when documentation indicates a specific disorder of bile acid or cholesterol metabolism that does not have a more precise ICD-10-CM code. This includes conditions like cerebrotendinous xanthomatosis (CTX) or other rare genetic defects affecting bile acid synthesis or cholesterol transport. Supporting documentation should clearly identify the specific metabolic defect or the clinical diagnosis of an "other" specified disorder.

• Ensure the medical record explicitly states a disorder of bile acid or cholesterol metabolism that is not better captured by more specific codes within the E78.XX category.
• Avoid using this code for general hypercholesterolemia or dyslipidemia; those conditions have more specific codes (e.g., E78.0-E78.5).
• Always review the full clinical picture and diagnostic test results (e.g., lipid panels, bile acid profiles) to confirm the appropriateness of this "other specified" code.
