Other follicular cysts of the skin and subcutaneous tissue

This code represents benign, fluid-filled sacs originating from hair follicles or sebaceous glands, excluding steatocystoma multiplex, milia, and other specified follicular cysts. These lesions are typically asymptomatic but can become inflamed or rupture. They are distinct from epidermal cysts, which arise from epidermal tissue.

Use this code for documented diagnoses of follicular cysts of the skin or subcutaneous tissue that are not specifically classified elsewhere (e.g., sebaceous cyst, trichilemmal cyst, pilar cyst). Documentation should clearly identify the lesion as a follicular cyst and rule out other specific types.

• Ensure the physician's documentation specifies "follicular cyst" and not a generic "skin cyst" to support this code.
• Differentiate from L72.1 (Trichilemmal cyst) and L72.2 (Steatocystoma multiplex), which have their own specific codes.
• If the cyst is inflamed or infected, consider an additional code for the associated condition (e.g., L08.9 for local infection).
