CPT Code 31231: Nasal Endoscopy, Diagnostic, Unilateral or Bilateral

Yes, but only once per encounter. The code includes unilateral or bilateral examination.

Yes, diagnostic nasal endoscopy (CPT 31231) is typically performed in-office by ENT specialists using a flexible or rigid endoscope. It allows direct evaluation of the nasal passages, the nasal cavity, and sinus openings.
