Clinical Context
A typical patient is a 45-year-old adult presenting to an outpatient dermatology clinic with a small, symptomatic epidermal inclusion cyst or a benign-appearing papule located on the trunk, arm, or leg. The patient reports intermittent irritation and occasional drainage from the lesion. The dermatologist performs a focused history and physical, documents lesion size at 0.5 cm diameter or less, confirms benign appearance or patient preference for removal, obtains informed consent, and performs a simple excision or destructive removal in clinic under local anesthesia. The procedure includes cleansing, local infiltration with lidocaine (with or without epinephrine), removal of the lesion down to dermal/epidermal level, hemostasis, and dressing. Post-procedure instructions are given, wound care discussed, and specimen sent for pathology only if clinically indicated. Typical site of service is an outpatient dermatology clinic, ambulatory surgical center, or primary care office equipped for minor procedures. Billing uses 11300 for removal of a single epidermal or dermal lesion ≤0.5 cm on the trunk, arms, or legs; documentation should include lesion size, location, method of removal, anesthesia, and any complications or additional services provided.
