ICD-10 Code E88.1 – Lipodystrophy, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E88.1 – Lipodystrophy, not elsewhere classified
What it is
E88.1 identifies lipodystrophy, a disorder involving abnormal loss or redistribution of body fat. Use it when documentation describes acquired or generalized fat loss patterns that do not fit a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings include visible loss of subcutaneous fat, altered body contour, and sometimes metabolic abnormalities such as insulin resistance or hypertriglyceridemia.
When to use this code
Use this code when the provider documents lipodystrophy without naming a more specific subtype. It also applies when the chart notes abnormal fat loss or redistribution and the clinician confirms lipodystrophy as the diagnosis. Check documentation if the cause is congenital, medication-related, or part of another syndrome.
Do not use for
Do not use E88.1 for simple weight loss, cachexia, or general malnutrition. If the record identifies a different underlying disorder or a more specific lipodystrophy type, code that condition instead.
Coding tip
Query the provider when the note mentions fat loss but does not clearly state lipodystrophy.
