About Nasal/sinus Endoscopy Surgery
CPT code 31288 refers to nasal/sinus endoscopy surgery (billing description: "Nasal/sinus endoscopy surg"). Under the 2026 Medicare Physician Fee Schedule, it is reimbursed at $198 in a facility (hospital or surgery center) and $198 in a doctor's office.
The Medicare rate is the closest thing to an objective "what this work is actually worth." A fair cash price for the uninsured is generally 1.5–3x that rate. Hospital sticker (gross) charges are often far higher — but almost nobody actually pays them.
