Epidermal cyst
ICD-10 L72.0 is a billable code used to indicate a diagnosis of epidermal cyst.
Epidermal cysts, also known as epidermoid cysts, are benign, closed sacs filled with keratin that form within the epidermis or the upper layer of the dermis. These cysts are commonly found on the face, neck, and trunk, but can occur anywhere on the body. Clinically, they present as small, round, firm nodules that may be skin-colored or slightly yellowish. While they are generally asymptomatic, they can become inflamed or infected, leading to pain and discomfort. The cysts arise from hair follicles or skin glands, and their contents can vary in consistency. Disease progression is typically slow, and they may remain stable for years. Diagnosis is primarily clinical, based on physical examination, but imaging studies may be employed in atypical cases to rule out other conditions. Differential diagnoses include lipomas, sebaceous cysts, and other skin lesions. Accurate diagnosis is crucial to avoid unnecessary surgical interventions.

L72.0 specifically covers epidermal cysts, which are benign cystic lesions filled with keratin. It does not include other types of cysts such as pilar cysts or steatocystomas, which have their own specific codes.
L72.0 should be used when the clinical presentation clearly indicates an epidermal cyst. If the cyst is sebaceous or of another type, the appropriate related code should be selected based on the specific characteristics and location of the cyst.
Documentation should include a detailed description of the cyst's size, location, and any symptoms such as pain or inflammation. Photographic evidence may also support the diagnosis, along with notes on any previous treatments or interventions.
