Balloon sinuplasty typically costs between $2,000 and $7,000 without insurance. If you have coverage, most insured patients pay somewhere between $0 and $1,500 out of pocket after their deductible and coinsurance. The final number depends on where the procedure is performed, how many sinuses are treated, and what your insurance plan looks like.
What Drives the Price
The single biggest factor in what you’ll pay is whether the procedure happens in a doctor’s office or an operating room. Research comparing the two settings found that office-based sinus procedures averaged about $2,737 in total charges, while the same type of work done in an operating room averaged $7,330. That’s nearly three times the cost, mostly because hospital and surgery center facilities tack on room fees, equipment charges, and anesthesia costs that don’t apply in an office setting.
The number of sinuses being treated also matters. Each sinus (maxillary, frontal, sphenoid) is billed as a separate procedure with its own billing code. If your doctor dilates one sinus on each side, that’s two procedures. If all three pairs need work, you’re looking at up to six. More sinuses means a higher total bill.
Geography plays a role too. Providers in major metro areas and high cost-of-living regions generally charge more than those in smaller cities or rural areas. It’s worth calling a few ENT offices in your area to compare quotes, especially if you’re paying out of pocket.
What Insurance Typically Covers
Most major insurers, including Medicare, cover balloon sinuplasty when it meets their criteria for medical necessity. That means you can’t simply request the procedure because you’re tired of sinus pressure. Insurers require documentation that conservative treatments have failed first.
A representative policy from Cigna lays out what most plans require for chronic sinusitis coverage. You need to have had at least two symptoms (nasal obstruction, discolored drainage, facial pain or pressure, reduced sense of smell) lasting more than three consecutive months. A CT scan has to confirm the problem, showing things like thickened tissue, fluid levels, or blocked sinuses. And you need to have tried and failed at least eight consecutive weeks of medical treatment, including antibiotics, a steroid nasal spray, an antihistamine or decongestant spray, and saline rinses.
For recurrent acute sinusitis, the bar is slightly different: four or more episodes per year, plus endoscopy findings and CT evidence of blockage.
If your insurer approves the procedure, your out-of-pocket share depends on your specific plan. Copays, deductibles, coinsurance percentages, and whether you’ve hit your out-of-pocket maximum all factor in. Call your insurance company with the relevant billing codes (31295 for maxillary sinus, 31296 for frontal, 31297 for sphenoid) and ask for a pre-authorization estimate before scheduling.
Medicare Reimbursement
Medicare covers balloon sinuplasty and has been paying for a growing number of these procedures. Total Medicare reimbursements for balloon dilation grew from roughly $11.8 million in 2011 to nearly $64 million in 2017. The average reimbursement per procedure has held steady at around $1,455 to $1,519 since 2013. If you’re on Medicare, your 20% coinsurance on the approved amount would put your share in the range of a few hundred dollars per procedure, assuming you’ve met your Part B deductible.
How It Compares to Traditional Sinus Surgery
Traditional endoscopic sinus surgery (often called FESS) involves physically removing tissue and bone to open blocked sinuses. It’s done under general anesthesia in an operating room, which means higher facility fees, anesthesia charges, and a longer recovery. Total costs for FESS commonly run $8,000 to $20,000 or more before insurance.
Balloon sinuplasty is less invasive. It uses a small inflatable catheter to widen the sinus openings without cutting tissue, and it can often be done in an office with local anesthesia. That’s a big part of why the sticker price is lower. Interestingly, aggregate Medicare payments to balloon sinuplasty providers have increased by 450% and now exceed total payments for traditional endoscopic sinus surgery, largely because the procedure has become so popular rather than because individual procedures cost more.
Costs Beyond the Procedure Itself
The quoted price for balloon sinuplasty doesn’t always include everything. Before the procedure, you’ll need a CT scan of your sinuses, which can run $200 to $800 depending on the facility and your insurance. You’ll also have a consultation visit with the ENT beforehand and at least one follow-up visit afterward. If the procedure is done in a surgery center rather than an office, separate bills for the facility fee and anesthesia are common.
Ask your provider’s office for an itemized estimate that includes the surgeon’s fee, any facility charges, anesthesia (if applicable), and the CT scan. Knowing the full picture upfront prevents surprises.
Paying Without Insurance
If you’re uninsured or your plan doesn’t cover the procedure, the $2,000 to $7,000 range is what most providers charge for self-pay. Some offices offer cash-pay discounts or bundled pricing that rolls the consultation, CT scan, and procedure into one flat rate. It’s always worth asking.
Healthcare financing through companies like CareCredit is another option. These credit cards offer promotional financing periods, sometimes interest-free for 6 to 24 months, that let you spread payments over time. They’re accepted at many ENT practices. Just read the terms carefully, because deferred-interest plans can charge you retroactive interest on the full balance if you don’t pay it off within the promotional window.
Choosing an in-office procedure over a hospital or surgery center setting is the most straightforward way to lower your total cost. If your ENT offers both options and your case is appropriate for an office-based approach, you could save thousands.
