Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 31002 covers

This service involves introducing irrigation fluid into the sphenoid sinus and flushing or clearing its contents. Otolaryngologists typically perform it for a patient with sphenoid sinus disease and retained secretions, often in an office or outpatient setting. The record should identify the sphenoid sinus treated and describe the irrigation performed; symptoms or a diagnosis alone do not establish that lavage occurred.

Report the code for the sphenoid sinus irrigation itself, rather than for operative exploration or creation of a sinus opening. If both sphenoid sinuses are treated, CMS recognizes bilateral reporting with modifier 50, paid at 150%. The service has a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.
