About 42720: Pharyngeal abscess drainage, intraoral approach
Reports surgical drainage of a pharyngeal abscess through the mouth, typically when an ENT surgeon accesses a deep throat collection intraorally.
An otolaryngologist typically uses this service to open and drain a pharyngeal abscess through the mouth, often in an operating room when a deep throat infection requires surgical drainage. The operative report should identify the pharyngeal collection, document the intraoral route, and describe the incision and drainage performed. This is distinct from drainage of a peritonsillar abscess or drainage of a pharyngeal abscess through an external incision.
Report one service for the abscess drainage and support the code with the location and surgical approach in the operative documentation. Medicare assigns 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 other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
