ICD-10 Code E88.13 – Localized lipodystrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E88.13 – Localized lipodystrophy
What it is
Localized lipodystrophy means a limited loss or abnormal distribution of subcutaneous fat in one body area. It is coded when documentation identifies a focal fat change rather than a generalized lipodystrophy disorder.
Clinical signs
Findings may include visible fat loss, contour changes, or a localized depressed area of skin and soft tissue. Clinical features vary; refer to documentation for the exact site and cause.
When to use this code
Use E88.13 when the record clearly states localized lipodystrophy or a focal lipodystrophic change. This is appropriate when the provider documents an isolated area of fat loss, often with a specific anatomic location.
Code it only when the condition is the diagnosis being addressed, not simply a cosmetic concern or nonspecific body habitus change. Check documentation if the note describes fat atrophy from injections, trauma, or another underlying disorder.
Do not use for
Do not use this code for generalized lipodystrophy, obesity, or simple weight loss. Do not assign it when the chart only mentions scarring, skin thinning, or an unspecified soft-tissue defect.
Coding tip
Look for the word “localized” and a documented body site before coding; if the cause is unclear, check documentation.
