Minimally Invasive Sinus and Eustachian Tube Procedures - Medicare Advantage

This policy addresses minimally invasive sinus and Eustachian tube procedures — including balloon sinuplasty, Eustachian tube balloon dilation (e.g., Acclarent Aera), steroid‑releasing Propel implants, and RhinAer — for adults with chronic rhinosinusitis, chronic Eustachian tube dysfunction, or chronic rhinitis. The excerpt provides no explicit coverage criteria (age limits, prior‑therapy or frequency requirements) and notes limitations including primarily adult populations, short‑term/low‑quality evidence, and the need to submit supporting documentation for unlisted CPT codes; consult the full policy for definitive requirements and exclusions.

"Sinus conditions that indicate a need for sinus surgery include acute, subacute or chronic rhinosinusitis (CRS)"
