Trichodermal cyst
ICD-10 L72.12 is a billable code used to indicate a diagnosis of trichodermal cyst.
Trichodermal cysts, also known as epidermoid cysts, are benign, slow-growing lesions that arise from the hair follicles and are typically filled with keratin. They can occur anywhere on the body, but are most commonly found on the face, neck, and trunk. Clinically, these cysts present as firm, round nodules that may be skin-colored or slightly discolored. They are often asymptomatic but can become inflamed or infected, leading to pain and discomfort. The underlying anatomy involved includes the epidermis and the dermis, where the cyst forms from the infundibulum of the hair follicle. Disease progression is generally benign, but complications may arise if the cyst ruptures or becomes infected. Diagnostic considerations include a thorough clinical examination and, if necessary, imaging studies to differentiate from other skin lesions. A biopsy may be performed to confirm the diagnosis, particularly if there is suspicion of malignancy. Accurate diagnosis is crucial for appropriate management and to avoid unnecessary surgical interventions.

L72.12 specifically covers trichodermal cysts, which are benign cystic lesions originating from hair follicles. They are characterized by a keratin-filled sac and can be confused with other cyst types, such as sebaceous cysts or lipomas.
L72.12 should be used when the diagnosis is specifically identified as a trichodermal cyst. If the lesion is not confirmed as such or is a different type of cyst, other codes like L72.11 or L72.9 may be more appropriate.
Documentation should include a detailed clinical examination note describing the cyst's characteristics, location, and any symptoms. Imaging studies or biopsy results confirming the diagnosis may also be necessary for comprehensive documentation.
