ICD-10 Code E78.89 – Other lipoprotein metabolism disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E78.89 – Other lipoprotein metabolism disorders
What it is
E78.89 identifies lipid or lipoprotein metabolism problems that do not fit a more specific ICD-10 category. Use it for documented disorders involving abnormal lipoproteins when the record does not support a different, named code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have abnormal lipid testing, known dyslipidemia, or provider-documented lipoprotein metabolism disorder without a more specific subtype.
When to use this code
Use E78.89 when the clinician documents an “other” lipoprotein metabolism disorder or a specific lipoprotein abnormality that is not separately indexed. It is also appropriate when the chart supports a lipoprotein disorder but lacks enough detail for a more precise code. Do not guess the subtype.
Do not use for
Do not use this code for general hyperlipidemia, pure hypercholesterolemia, or hypertriglyceridemia when those diagnoses are documented. If the record names a specific lipid disorder, code that condition instead.
Coding tip
Check the provider’s exact wording and index the documented lipid disorder before defaulting to E78.89.
