How to appeal a Balloon Sinuplasty / Sinus Surgery denial
Sinus procedure denials are driven by the chronic-sinusitis criteria, prior auth, and CT documentation, payers require documented failed medical therapy and CT evidence of sinus disease before covering balloon dilation or FESS.
Common code: CPT 31295-31298 (balloon dilation), 31256/31267/31276/31288 (functional endoscopic sinus surgery)Why it gets denied
- The payer requires documented failed appropriate medical therapy (antibiotics, nasal steroids) and it wasn't shown
- CT evidence of sinus disease didn't meet the coverage policy
- Prior authorization was missing or didn't cover all the sinuses treated
- Balloon dilation was denied as investigational for the specific sinus, or bundled with FESS
What overturns it
- Document the failed medical-therapy trial (duration and agents) that meets the policy
- Submit the CT findings confirming chronic sinusitis in the treated sinuses
- Obtain prior auth for each sinus treated and tie it to the claim
- Separate the medically necessary balloon and FESS codes per sinus with the operative note
Worth appealing? Sinus procedures carry high surgical professional fees, and denials are systematic policy gates. They're recoverable when the failed-medical-therapy history and CT findings are documented to the payer's chronic-sinusitis criteria.
