Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the L72 range.
Epidermal Cyst
Intradermal or subcutaneous saclike structure, the wall of which is stratified epithelium containing keratohyalin granules.
Steatocystoma Multiplex
A disorder characterized by multiple, wide spread cutaneous cysts that often become inflamed and rupture. It is caused by the same mutations in the gene coding for KRT-17 that are causative mutations for Pachyonychia congenita, Type 2. Natal teeth involvement is sometimes associated with steatocystoma multiplex.
About the L72 Code Range
ICD-10 codes L72 through L72.9 cover various types of follicular cysts of the skin and subcutaneous tissue, such as epidermal, pilar, and sebaceous cysts. These codes are used to classify specific cyst conditions for accurate diagnosis and treatment documentation.
These codes help medical coders identify precise types of skin cysts. For example, L72.0 refers to epidermal cysts, commonly known by terms like "epidermoid cyst" or "milia," including cysts in locations such as the breast or scalp. The L72.1 series includes pilar cysts (or trichilemmal cysts), usually found on the scalp. L72.2 denotes steatocystoma multiplex, a condition involving multiple sebaceous cysts, sometimes associated with natal teeth syndrome. L72.3 identifies sebaceous cysts, described also as masses or cysts on fingers, eyelids, or scrotum. Other follicular cysts that don’t fit these categories fall under L72.8, while L72.9 is used when the follicular cyst is unspecified. Understanding these distinctions supports selecting the correct ICD-10 code for conditions described by synonyms like "cyst of skin," "epidermoid cyst," or "pilar cyst," aiding clarity in medical records and billing.
