Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to an otolaryngology or facial plastic clinic with a non-healing nasal or facial lesion suspicious for malignancy or a recurrent skin cancer after prior excision. The patient has a lesion localized to the nasal ala, tip, or perioral region requiring precise histopathologic mapping and margin control. The clinical workflow begins with an outpatient evaluation including history, focused head and neck exam, and office photography. Local anesthesia is administered and the lesion is excised using staged Mohs micrographic surgical technique with immediate frozen-section microscopic analysis to confirm clear peripheral and deep margins. Reconstruction is planned either primarily or with local flap or graft once margins are confirmed. Perioperative documentation includes lesion size, anatomic location, number of Mohs stages, frozen-section results, and specific reconstruction method. Typical sites of service are hospital outpatient departments or ambulatory surgical centers where frozen pathology and reconstructive resources are available.
