Clinical & Coding Specifications
Clinical Context
A typical patient is an adult referred to an otolaryngologist or head and neck surgeon for evaluation of chronic nasal obstruction, epistaxis, or suspected nasal cavity mass. The clinical workflow includes history and physical exam, nasal endoscopy in the clinic to visualize mucosa and nasal passages, and potential biopsy of a suspicious lesion or targeted inspection of the nasopharynx. Pre-procedure preparation includes coagulation assessment for patients on anticoagulants, informed consent, topical anesthesia and decongestant application for in-office nasal endoscopy, or general anesthesia planning if performed in the operating room. Post-procedure workflow includes specimen handling for pathology if a biopsy is taken, procedure documentation, and brief recovery with discharge instructions. Typical site of service is an outpatient ambulatory clinic or outpatient surgical center depending on whether the procedure is diagnostic endoscopy alone or combined with operative biopsy or removal.
