ICD-10 Code L72.8 – Other follicular cysts of the skin and subcutaneous tissue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L72.8 – Other follicular cysts of the skin and subcutaneous tissue
What it is
L72.8 identifies follicular cysts of the skin or subcutaneous tissue that do not fit a more specific cyst category. These are usually benign, localized cystic lesions arising from hair follicle structures.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe a small, round, movable skin or subcutaneous lump, sometimes with a central punctum or intermittent drainage.
When to use this code
Use L72.8 when the provider documents an “other follicular cyst” or a follicular cyst that is not otherwise specified by a more exact code. It also fits when the lesion is described as benign and follicular in origin, but the record does not support a more specific cyst type.
Do not use for
Do not use this code if the documentation identifies a specific cyst, such as a sebaceous, epidermoid, or pilonidal cyst. Check documentation when the lesion is not clearly follicular or when another diagnosis better explains the finding.
Coding tip
Code the most specific cyst term documented; if the record only says “skin cyst,” confirm whether the provider meant a follicular cyst.
