ICD-10 Code E65 – Localized adiposity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E65 – Localized adiposity
What it is
Localized adiposity means a limited area of excess fatty tissue, often described as a localized fat deposit. It is a descriptive diagnosis, not a systemic disease.
Clinical signs
Findings usually include a clearly defined area of increased subcutaneous fat with a visible contour change. Clinical features vary; refer to documentation.
When to use this code
Use E65 when the record documents localized fat accumulation or a focal fatty deposit without another more specific diagnosis. It may appear in cosmetic, body-contour, or exam documentation. Code it only when the provider identifies the finding as localized adiposity.
Do not use for
Do not use this code for generalized obesity, edema, or a mass that is not documented as fat. If the note suggests another condition, check documentation.
Coding tip
Assign E65 only when the provider clearly documents localized adiposity; otherwise, query or code the documented condition.
