- "Sinus surgery" covers several procedures, so the price depends heavily on which one your ENT recommends and where it is done.
- In-office balloon sinuplasty is generally the least expensive setting; hospital operating-room endoscopic surgery (FESS) is the most expensive.
- Published price ranges are estimates only — the actual bill is a bundle of facility, surgeon, anesthesia, and imaging charges that vary by region and year.
- Most medical (not dental) insurance covers sinus surgery when it is medically necessary and conservative treatment has failed, though prior authorization is common.
- The single most useful step before scheduling is to get an itemized, written estimate for the specific procedure and CPT codes at more than one facility.
Chronic sinusitis (chronic rhinosinusitis) affects tens of millions of adults in the United States, and when antibiotics, steroids, nasal sprays, and rinses stop controlling symptoms, surgery often becomes the next conversation. The sinus surgery cost can range from a few thousand dollars for a straightforward in-office balloon sinuplasty to well over $30,000 for complex endoscopic surgery performed in a hospital operating room. That enormous gap is exactly why it pays to understand what you are actually being billed for before you agree to a procedure. If you are researching medical expenses more broadly, our healthcare costs guide can help you compare across specialties.
A quick but important caveat: the figures below are estimates and typical ranges reported for the U.S. market, not fixed prices. Actual costs vary by region, facility, surgeon, your specific anatomy, and the year of your procedure. Nothing here is a quote. The only number that truly applies to you is the written estimate you obtain for your specific procedure and billing codes.
Average Sinus Surgery Cost by Procedure Type
The term “sinus surgery” covers several different procedures, and the price depends largely on which one your ENT (ear, nose, and throat) specialist recommends. Here are the most common types and the price ranges commonly cited for patients paying without insurance. Treat them as ballpark estimates, not guarantees.
Balloon sinuplasty (in-office): commonly cited around $3,000 to $7,000. This minimally invasive procedure threads a small balloon into a blocked sinus opening and inflates it to widen the passage. Many ENTs now perform it under local anesthesia in their office, which tends to reduce cost substantially. Peer-reviewed literature indexed by the National Institutes of Health has documented the rapid growth of in-office balloon procedures, driven partly by lower facility costs and faster recovery for appropriately selected patients.
Balloon sinuplasty (operating room): commonly cited around $8,000 to $15,000. When the same procedure is performed in a hospital or ambulatory surgery center under general anesthesia, it typically costs considerably more because of facility fees and anesthesia charges.
Functional endoscopic sinus surgery (FESS): commonly cited around $10,000 to $30,000. FESS is widely described as the standard operation for chronic sinusitis that has not responded to medical therapy. The surgeon uses an endoscope to remove tissue, polyps, or bone that blocks sinus drainage. The estimate varies based on how many sinuses are involved and whether polyp removal or septoplasty is done at the same time.
Septoplasty combined with sinus surgery: commonly cited around $12,000 to $35,000. Many patients with chronic sinusitis also have a deviated septum. Combining septoplasty with FESS adds operating time and cost. For septoplasty-specific pricing, see our deviated septum surgery cost guide.
Image-guided (navigation) sinus surgery: often adds roughly $1,000 to $3,000. When anatomical complexity or a revision case calls for real-time CT navigation, the technology adds to the overall bill.
What Makes Up the Total Bill?
Your sinus surgery cost is a combination of several separate charges, often billed by different entities. Understanding each component helps you see where you might be able to negotiate or save, and why two quotes for “the same surgery” can differ by thousands of dollars.
Facility fee: often the largest single line item. This covers the operating room, recovery area, nursing, and supplies. In-office procedures avoid this charge almost entirely, which is a big reason in-office balloon sinuplasty is so much cheaper. Hospital outpatient departments generally charge the most, followed by ambulatory surgery centers.
Surgeon fee: the ENT surgeon’s professional fee covers the procedure and typically includes follow-up visits during the global surgical period (often the first 90 days). Surgeons who subspecialize in rhinology or skull base surgery may charge more.
Anesthesia: general anesthesia is standard for FESS, while balloon sinuplasty may use only local anesthesia with light sedation, which lowers cost. Anesthesia is usually billed in time increments, so longer surgeries cost more.
Pre-operative CT scan: a CT scan of the sinuses is generally required before surgery to map the anatomy. Some surgeons fold this into their evaluation; others bill it separately. Imaging can add several hundred dollars or more depending on where it is done.
Sinus Surgery Cost With Insurance
Sinus surgery is a medical procedure, so it is covered by medical insurance rather than dental insurance. Most private health plans cover it when conservative treatments have failed and the surgery is deemed medically necessary. Your ENT will typically need to document a period of medication therapy — often several weeks to a few months — and imaging before your insurer approves surgery. Prior authorization is common, so confirm it in advance.
What you actually pay depends on your plan’s deductible, coinsurance, and out-of-pocket maximum, not on the sticker price. As an illustration only: on a plan with a deductible you have not yet met plus coinsurance, you would generally pay the deductible plus your coinsurance share up to your annual out-of-pocket maximum, after which the plan covers the rest. Read your Summary of Benefits and Coverage, or call the number on your insurance card, to model your specific numbers.
Medicare covers medically necessary sinus surgery, with outpatient endoscopic procedures generally falling under Part B. Under Medicare, the surgeon’s fee and the facility fee are paid separately, and you are typically responsible for the Part B deductible plus 20 percent coinsurance after meeting it. Medicare’s deductibles and allowed amounts are reset each year, so check the current figures at Medicare.gov rather than relying on a number from an old article. A Medigap (Medicare Supplement) plan can cover much or all of the remaining share.
Sinus Surgery Cost Without Insurance
Uninsured patients are often quoted the chargemaster rate, which is the highest price a facility lists. There are, however, several legitimate ways to bring that number down.
Many ENT practices offer cash-pay pricing for in-office balloon sinuplasty that bundles the surgeon, local anesthesia, and the balloon device. For patients whose anatomy makes them good candidates, this is frequently the most affordable route.
For more complex FESS, hospitals commonly offer self-pay or prompt-pay discounts that reduce the bill meaningfully, and some ambulatory surgery centers advertise all-inclusive package pricing. The discount you are offered will vary, so always request an itemized estimate in writing before scheduling and ask specifically whether the quote is all-inclusive or whether anesthesia, pathology, and imaging are billed separately.
Factors That Influence Your Final Price
Several variables drive the wide cost range for sinus surgery.
Number of sinuses treated: humans have four pairs of paranasal sinuses. Treating all of them costs more than treating two or three, and the CPT billing codes change based on which sinuses the surgeon addresses.
Polyp removal: nasal polyps are common in chronic sinusitis. Removing them adds complexity and operating time, which increases the bill.
Revision surgery: if you have had previous sinus surgery, revision procedures are more complex because of scar tissue and altered anatomy. Revision FESS generally costs more than primary surgery, a pattern reflected in PubMed-indexed research on revision endoscopic outcomes.
Location: medical centers in high-cost-of-living urban areas tend to charge significantly more than facilities in smaller markets for the same CPT codes.
Setting: in-office procedures are generally cheapest, followed by ambulatory surgery centers, then hospital outpatient departments. For appropriately selected patients, the clinical outcome for balloon sinuplasty is broadly similar across settings, as organizations such as the Mayo Clinic describe.
How to Save on Sinus Surgery
Ask about in-office options. If you are a candidate for balloon sinuplasty, having it done in your ENT’s office rather than an operating room can save thousands of dollars. Not every patient qualifies, but it is worth asking.
Compare facility prices. Under the federal Hospital Price Transparency rule enforced by CMS, hospitals are required to publish standard charges, including negotiated rates. Check at least two hospitals and one ambulatory surgery center before committing; the difference for the same codes can be large.
Use an ambulatory surgery center. ASCs frequently charge less than hospital outpatient departments for outpatient sinus surgery. Ask your surgeon which ASCs they operate at and request a bundled quote.
Time your procedure wisely. If you have already paid a significant amount toward your deductible earlier in the plan year, scheduling before your plan resets means your insurance may cover a larger share. Starting fresh in a new plan year usually means paying the full deductible again.
Appeal insurance denials. If your insurer denies coverage, you have the right to appeal, and a substantial share of appeals are overturned when the request is well documented. Ask your ENT’s office to supply records showing failed conservative treatment, and use both the internal appeal and, if needed, external review. Your plan documents and CMS explain the appeal steps.
Frequently Asked Questions
Is sinus surgery worth the cost?
For patients with chronic sinusitis that does not respond to medication, research consistently reports meaningful quality-of-life improvement after surgery. Studies indexed in otolaryngology journals have found sustained symptom relief and reduced medication use for years after FESS in appropriately selected patients. The upfront cost may also reduce long-term spending on antibiotics, specialist visits, and missed work. Whether it is right for you is a decision to make with your ENT.
Does insurance cover balloon sinuplasty?
Most major medical plans now cover balloon sinuplasty when it is medically necessary, but coverage policies vary. Some insurers require prior authorization or documentation that you tried several weeks of medical therapy first. Confirm the specifics with your plan before scheduling.
How much does sinus surgery cost with Medicare?
Under Medicare, outpatient endoscopic sinus surgery is generally covered, with the facility and surgeon fees paid separately. You are typically responsible for the annual Part B deductible and 20 percent coinsurance, and a Medigap plan can cover most or all of the remainder. Because Medicare resets these amounts each year, check the current deductible and allowed amounts at Medicare.gov.
Can I get sinus surgery at an ambulatory surgery center?
Yes. The majority of sinus surgeries are outpatient and are well suited to ASCs. The Cleveland Clinic notes that outpatient sinus surgery is safe and effective for most patients, often with lower costs and shorter wait times than a hospital setting.
What is the difference between balloon sinuplasty and FESS?
Balloon sinuplasty widens sinus openings without removing tissue and suits certain patterns of sinus disease, often in the office. FESS removes obstructing tissue, polyps, or bone and is used for more extensive disease, usually in an operating room. Your ENT decides which is appropriate based on your CT scan and symptoms — the two are not interchangeable for every patient.
What to Do Next
If your ENT has recommended sinus surgery, start by asking exactly which procedure and CPT codes will be billed. Get itemized written estimates from at least two facilities, ask whether in-office balloon sinuplasty is an option for your condition, and verify your insurance benefits, including any pre-authorization requirement. Because the difference between the most and least expensive options for the same procedure can easily reach five figures, careful comparison is one of the most valuable things you can do before scheduling.
Sinus surgery is not one price but a bundle of charges that swings from a few thousand dollars (in-office balloon sinuplasty) to well over $30,000 (complex hospital FESS). Every figure in this guide is an estimate, not a quote. It is covered by medical, not dental, insurance when medically necessary. Before you schedule, get an itemized written estimate for your specific procedure and codes at more than one facility, and confirm your coverage.
