The Sinus Blog

Balloon sinuplasty cost is decided by three things: where the procedure is performed, whether your insurer agrees it is medically necessary, and how much of your deductible you have already met this year. The sticker prices you find online skip all three, which is why they range so widely.

Dr. Brad Bichey, a board-certified ENT, has performed balloon sinuplasty in the office at Indiana Sinus Centers in Carmel and Fort Wayne for more than a decade. This guide covers the answers he gives in the exam room: what the published numbers mean, why the setting matters more than the surgeon’s fee, what Indiana insurers require before they pay, and what your share looks like with and without coverage.

Why the numbers you find online are misleading

Most “how much does balloon sinuplasty cost” figures are billed charges, and billed charges are not what anyone pays. A billed charge is the list price a facility submits. The insurer then applies its contracted rate, called the allowed amount, and your share is a slice of that allowed amount based on your plan.

The same problem shows up with septoplasty, where published estimates can differ by tens of thousands of dollars between sources because some quote hospital list prices and others quote outpatient contracted rates. Dr. Aaron Feinstein’s practice explains this in its guide to what deviated septum surgery costs, and the logic applies to balloon dilation just as well.

The useful number is your estimated out-of-pocket amount, which requires your plan details. Indiana Sinus Centers built a sinus procedure cost estimator for exactly this reason. You enter your deductible status, coinsurance percentage and remaining out-of-pocket maximum, and the office returns a personalized, non-binding estimate rather than a generic range.

Where the procedure is done is the biggest cost driver

The setting of your procedure moves the bill more than any other single factor. Sinus balloon surgery cost breaks into a surgeon’s fee, a facility fee and an anesthesia fee, and the last two disappear or shrink when the procedure moves out of the hospital.

In a hospital operating room, you pay the surgeon, the hospital’s facility charge and an anesthesiologist for general anesthesia. In an ambulatory surgery center, the facility fee is lower but still present, and anesthesia is still billed separately. In a physician’s office under local anesthesia, there is no separate facility charge and no anesthesiologist on the claim.

How Indiana Sinus Centers keeps the setting simple

Dr. Bichey performs balloon sinuplasty in the office using local and oral sedation, which is one reason the procedure fits chronic sinusitis treatment for patients who cannot afford a hospital-level bill or cannot take a week away from work. Most patients drive home the same day, and balloon sinuplasty recovery takes a day or two for most people.

Dr. Joseph Capo’s office on Long Island notes in its balloon sinuplasty FAQ that the in-office approach means no hospitalization and no anesthesiologist, which is where most of the savings against traditional sinus surgery come from.

Is balloon sinuplasty covered by insurance?

Yes, most commercial plans and Medicare cover balloon sinuplasty when the medical record shows it is necessary. The key word is documented. Insurers do not pay because you feel congested. They pay because the chart proves chronic rhinosinusitis that has not responded to medication.

The criteria are similar across payers. Symptoms must have lasted 12 weeks or longer, or you must have had repeated acute infections. You must have tried medical therapy first, usually a nasal steroid spray, saline irrigation and, when a bacterial infection was suspected, antibiotics. A CT scan must show disease in the specific sinus being dilated, and your symptoms must match the CT findings on that side. The procedure is billed under CPT code 31295 for the maxillary sinus, 31296 for the frontal and 31297 for the sphenoid. Dr. Hilel Swerdlin’s practice in Wisconsin lays out the same three documentation requirements in its guide to balloon sinuplasty coverage and candidacy.

The American Academy of Otolaryngology-Head and Neck Surgery backs this position. Its position statement on sinus dilation, revised in 2021, calls the technique an appropriate option for patients with chronic or recurrent acute rhinosinusitis who have failed medical management, with the diagnosis confirmed by endoscopy and CT.

The Indiana payer picture

UnitedHealthcare’s published policy covers balloon sinus ostial dilation on those criteria. Even so, Indiana Sinus Centers has seen the plan intermittently deny prior authorizations that meet its own written rules, which is why the practice publishes its balloon sinuplasty insurance coverage page for UnitedHealthcare with the criteria and a path for patients to file a complaint with the Indiana Department of Insurance. The AAO-HNS has raised the same concern nationally in its statement on reimbursement of balloon dilation.

What you pay with insurance

Balloon sinuplasty cost with insurance comes down to four numbers on your benefits summary: your deductible, your coinsurance percentage, your specialist copay and your remaining out-of-pocket maximum. If you have met your deductible, you typically owe coinsurance on the allowed amount until you hit the out-of-pocket cap. If you have not, you pay the allowed amount up to the deductible first.

Prior authorization comes before any of this. Indiana Sinus Centers submits the request with your CT report and treatment history, and the office will appeal a denial that contradicts the payer’s own policy. One point worth weighing is that balloon sinus dilation is a one-time cost, while nasal sprays, antibiotic courses and missed workdays recur every season.

Paying without insurance

Balloon sinuplasty cost without insurance is lower than most patients expect once the hospital is out of the picture, because the surgeon’s fee is the only fee. Ask for an all-in self-pay quote that includes the office visit, the CT review, the procedure and follow-up, so nothing arrives later as a surprise.

Medicare patients should not assume the answer is no. Medicare covers sinus and nasal airway procedures when the necessity criteria are met, and the practice’s Medicare information page explains its approach for patients over 65. Medicare Advantage plans run their own prior authorization, so bring that card.

Is it worth it? Success rate and how long it lasts

The balloon sinuplasty success rate holds up over years, not months, which is what makes the cost worth weighing against a lifetime of medication. In the REMODEL randomized trial, summarized in the UK’s NICE clinical evidence review of balloon sinus dilation, patients treated with balloon dilation improved their SNOT-20 symptom scores by 1.65 points at 24 months, matching the 1.45-point improvement after endoscopic sinus surgery. At 18 months, 2.7 percent of balloon patients needed revision surgery versus 6.9 percent of surgery patients, and 92 percent of balloon patients avoided post-operative debridement.

Is balloon sinuplasty permanent? Not in the strict sense, because the sinus lining can inflame again from allergies or new infections. The dilated opening itself tends to hold, and the procedure can be repeated if it does not. Atkins Sinus covers this trade-off in its review of balloon sinuplasty risks and benefits, including the rare complications that a hospital procedure shares.

Balloon dilation is not right for every patient. Large nasal polyps or a severely deviated septum usually call for a different plan, and the practice’s comparison of balloon sinuplasty vs FESS explains when each one fits.

Frequently asked questions

How much does balloon sinuplasty cost in Indiana?

It depends on the setting, your insurer’s allowed amount and your remaining deductible. An in-office procedure avoids facility and anesthesia fees, and the practice’s cost estimator gives a personalized figure once you supply your plan details.

Does insurance cover balloon sinuplasty?

Most commercial plans and Medicare cover it when you have 12 or more weeks of documented sinusitis, failed medical therapy and a CT scan confirming disease in the sinus being treated. Prior authorization is usually required.

How long does balloon sinuplasty last?

Trial data show symptom improvement holding at two years, with revision rates under 3 percent at 18 months. Allergies and new infections can still cause symptoms, and the procedure can be repeated.

What is the sinusitis surgery price compared with balloon sinuplasty?

Endoscopic sinus surgery in a hospital adds a facility charge and general anesthesia, so its total is usually well above an office-based balloon procedure. Your share still depends on your plan.

Get an estimate before you decide

What balloon sinuplasty will cost you is a number the office can calculate, not a range someone posted online. If you have had sinus symptoms for three months or more and sprays, rinses or antibiotics have not fixed them, you may already meet the coverage criteria. Dr. Bichey and his team will review your CT, verify your benefits and handle the prior authorization. Schedule a consultation at the Carmel or Fort Wayne office to find out where you stand.

You’ve had months of pressure, congestion, and infections that keep coming back, and now your doctor has ordered a sinus CT scan. You’re either waiting for the appointment or staring at a report full of terms like “mucosal thickening” and “opacification,” wondering how worried to be.

Here’s the reassuring part: a CT is the standard next step in a sinus workup, not a sign that something is seriously wrong. It’s how a specialist stops guessing. A physical exam, and even a nasal endoscopy, can only see the front of the nose. A CT of the sinuses shows the cavities and drainage pathways behind your face, the areas no exam can reach. If you’re still deciding whether your symptoms even warrant this step, start with the signs it’s time to stop self-treating.

This article covers what a normal scan looks like, what an abnormal one shows, why yours probably won’t involve dye, and what happens after an abnormal result.

What a sinus CT scan is and why your ENT ordered one

A sinus CT is a set of thin, cross-sectional X-ray images of your sinus cavities, reconstructed into three views: axial (from above), coronal (straight-on), and sagittal (from the side). ENTs spend most of their reading time in the coronal view because it shows the drainage pathways best. The scan takes 5 to 10 minutes, with no needle and no enclosed tube like an MRI; RadiologyInfo covers what to expect during a sinus CT. A cat scan of the sinuses and a nasal CT scan are the same study.

Doctors order a CT scan for sinus symptoms lasting 12 weeks or more, infections that keep returning, treatment that isn’t working, or surgical planning — the situations when advanced imaging becomes necessary. The images answer two questions no exam can: where the blockage sits, and how much disease is present. Those answers determine which treatments are even options.

A radiologist describes the findings. Dr. Brad Bichey, a board-certified otolaryngologist, reads them against your symptoms and scope exam. The report is data, not a decision.

What a normal sinus CT scan looks like

On a normal sinus CT scan, the sinus cavities are black. Black means air, and air means the sinus is open and draining the way it should. The bone around each cavity shows up white, and the healthy mucosal lining is so thin it’s barely visible.

A CT scan of healthy sinuses also shows clear drainage pathways (the ostiomeatal complex, which we’ll cover below), a septum that sits reasonably close to the midline, and turbinates — the structures that warm and humidify incoming air — that are normal in size.

If your scan comes back normal, that’s still a useful result. It rules out structural sinus disease and points the workup toward another cause of your facial pressure: allergies, non-allergic rhinitis, or migraine, which gets misdiagnosed as sinus headache far more often than most people expect. Each of those is a different treatment path.

What an abnormal sinus CT shows: what the ENT actually looks for

The report may say “abnormal,” but abnormal covers everything from trivial to surgical. If you’re trying to understand what a cat scan of the sinuses shows when something is wrong — or comparing a normal sinus CT scan vs abnormal — here’s what a specialist checks, in order.

Mucosal thickening

The sinus lining swells and shows up as a gray rim inside a cavity that should be black. Mild thickening is common, often incidental, and doesn’t need treatment by itself. Persistent thickening that matches your symptoms is what points toward chronic sinusitis.

Opacification

A sinus that appears gray or white instead of black, filled with fluid, inflamed tissue, or infection rather than air. This is what sinusitis on CT looks like, and partial versus complete opacification changes the picture significantly.

Ostiomeatal complex obstruction

The single most important finding. The ostiomeatal complex is the shared drainage corridor for the maxillary, ethmoid, and frontal sinuses. Block it and several sinuses back up at once — the anatomic reason some patients get infections that antibiotics only fix briefly.

Structural contributors

A deviated septum, concha bullosa (an air pocket inside a turbinate), enlarged turbinates, or simply narrow anatomy.

Other findings

Nasal polyps, retention cysts, fungal debris, and bone thickening left behind by long-standing inflammation.

Scoring

ENTs quantify the scan with the Lund-Mackay staging system, which grades each sinus for a total score of 0 to 24. Insurers and surgeons both pay attention to it. The findings then get weighed against the AAO-HNS diagnostic criteria for chronic rhinosinusitis, because imaging is one piece of the diagnosis, not the whole thing.

Normal vs. abnormal sinus CT at a glance

What the ENT checks	Normal scan	Abnormal scan
Sinus cavities	Black (air-filled, draining)	Gray or white (mucosal thickening, fluid, or opacification)
Sinus lining	Thin, barely visible	Thickened — the hallmark of chronic inflammation
Ostiomeatal complex	Open and clear	Narrowed or blocked; multiple sinuses back up
Septum and turbinates	Midline septum, normal turbinates	Deviation, concha bullosa, turbinate hypertrophy
Lund-Mackay score	0–2	Higher scores indicate more extensive disease
What it means for you	Structural sinus disease ruled out — look at allergy or other causes	Anatomy is contributing; a procedure may be an option

With or without contrast: why your scan probably doesn’t need dye

A standard sinus CT scan is done without contrast. Bone and air are already sharply different densities on CT, so the anatomy shows up clearly on its own — that built-in contrast is why sinus CT scanning works as a quick, needle-free study. Skipping the dye also means no IV, no risk of a dye reaction, and a lower cost.

Contrast is reserved for narrow situations: a suspected tumor, an abscess, or an infection spreading beyond the sinuses. If your ENT ordered a routine scan, none of those is what he’s looking for.

So if your imaging order says “CT sinuses without contrast,” nothing was left off. That’s the standard, expected study.

Why a CT is required before balloon sinuplasty is approved

If balloon sinuplasty is on the table, the CT stops being optional. Nearly every insurer requires two things before authorizing the procedure: documented sinus disease on a CT scan, and a documented failure of medical therapy — the antibiotics, nasal steroids, and rinses that didn’t hold. Without the scan, there’s nothing objective to submit.

The CT is also what proves the blockage is anatomic rather than allergic, and it drives the plan itself: which sinuses need treatment (maxillary, frontal, sphenoid), and whether a septum or turbinate problem should be addressed during the same visit.

At Indiana Sinus Centers, Dr. Bichey reads your scan against your symptom history and endoscopy findings to determine whether balloon sinuplasty is an option for you — here’s a closer look at how to know if you need balloon sinuplasty — and the same scan then anchors the insurance authorization.

Your CT came back abnormal — what happens next

Abnormal does not mean surgery. It means there’s a finding, and the finding now gets matched against how you actually feel. From there, treatment usually follows one of four paths:

• Mild findings with manageable symptoms: medical management first — nasal steroids, saline irrigation, allergy treatment, sometimes a short steroid course.
• A blocked drainage pathway after failed medical therapy: balloon sinuplasty becomes an option — in-office, local anesthesia, most patients back to normal activity within about 48 hours. Here’s how to prepare for the procedure.
• Polyps, extensive disease, or anatomy a balloon can’t reach: more involved endoscopic sinus surgery.
• A deviated septum or enlarged turbinates driving the blockage: those get corrected too, often at the same time.

The through-line: your treatment is decided by what the scan shows plus how you feel, never by the scan alone. One practical note — bring your imaging disc, or make sure the actual images (not just the written report) reach your ENT. Specialists want to see the slices. Haven’t been scanned yet? The sinus quiz takes two minutes.

The bottom line on your sinus CT

Black sinuses mean air, and air means open drainage. Gray or white means inflammation, fluid, or blockage. Of everything on the report, the state of the ostiomeatal complex — the shared drainage corridor — matters most, because it explains why infections keep returning and what a procedure could actually fix.

A CT is the point where a sinus workup stops being guesswork. If you’ve had one and don’t understand what it means, or you’ve had chronic sinus symptoms and no one has ordered one, schedule a consultation with Indiana Sinus Centers. Bring your images — we’ll walk through them with you.

Frequently asked questions

What does a sinus CT scan show?

It shows the sinus cavities and drainage pathways in cross-section. Open, healthy sinuses appear black because they’re filled with air. Inflammation, fluid, polyps, and blocked drainage pathways appear gray or white.

What does an abnormal sinus CT scan mean?

It means the scan found something — most often mucosal thickening, opacification, or a blocked ostiomeatal complex. It does not automatically mean you need surgery. The finding has to match your symptoms.

Does a sinus CT scan need contrast?

Usually not. Routine sinus CT is done without contrast. Contrast is added only when a tumor, abscess, or spreading infection is suspected.

Do I need a CT scan before balloon sinuplasty?

Yes. Nearly every insurer requires CT evidence of sinus disease plus failed medical therapy before authorizing the procedure.

How long does a sinus CT take?

About 5 to 10 minutes. No IV, no dye, and no enclosed tube.

It’s day eight. You still can’t breathe through your nose, your cheeks ache, and the tissue box has become permanent furniture. Is this still a cold, or has it turned into a sinus infection?

The sinus infection vs cold question is harder than it should be, and for a good reason: a cold causes sinus inflammation. Every cold is technically a brief, mild sinus event. In the first week, the two look almost identical from the inside.

The scale of the confusion is real. Adults average two to three colds a year, and about 1 in 8 U.S. adults gets diagnosed with sinusitis annually. Most of those “sinus infections” are viral.

Here’s the reassuring part: you don’t need a CT scan or a culture to sort this out. The clue isn’t in your symptoms. It’s in the clock.

Below: what actually separates the two, the 10-day rule, the double-worsening pattern, and what all of it means for antibiotics.

Why colds and sinus infections feel identical at first

A cold is a viral upper respiratory infection. The virus inflames the lining of your nose, and your sinuses drain through that same lining. Congestion, facial pressure, drainage, and headache all show up in a plain cold — which is exactly why a virus can set off sinus trouble without any bacteria involved, and why acute sinusitis so often follows one.

Early on, sinus infection vs cold symptoms are simply the same symptoms. Facial pressure is not evidence of a bacterial infection. “My face hurts, so I need an antibiotic” is the most common wrong turn patients take.

Dr. Brad Bichey, a board-certified ENT who has evaluated sinus complaints in Fort Wayne and Carmel for over a decade, hears this question daily in October and again in February. His answer starts with the calendar, not the symptom list. A cold peaks around day three to five, then improves. A bacterial sinus infection does not follow that curve.

Sinus infection vs. cold: what actually differs

So how do you know if you have a sinus infection? Read trajectory first, symptoms second. Three findings genuinely shift the odds toward bacterial sinusitis: a fever that returns after it had already broken, facial pain localized to one side or one sinus, and symptoms that get worse after you’d started improving. The single most useful question is how long a cold lasts versus a sinus infection — and the table below answers it.

Mucus color is not on that list. Green mucus does not mean bacteria, and clear mucus does not rule out an infection. The color question, along with whether allergies or an infection is behind it, is covered separately. It’s also worth knowing that several other conditions produce the same symptoms, which is another reason color guessing gets people nowhere.

Feature	Common cold	Sinus infection (acute sinusitis)
Typical duration	7–10 days; peaks days 3–5, then improves	Persists past 10 days, or worsens after improving
Trajectory	Steadily improves after the peak	Plateaus, or improves then gets distinctly worse
Fever	Low-grade or none, early only	May return or appear later in the illness
Facial pain / pressure	Mild, diffuse, both sides	Often localized — one cheek, one eye, upper teeth
Sore throat / sneezing	Common, especially early	Less prominent
Cause	Virus, always	Virus in most cases; bacterial in a minority
Antibiotics help?	No	Only if bacterial, and only when the 10-day or double-worsening criteria are met

The 10-day rule and double worsening

So when does a cold become a sinus infection? The AAO-HNS diagnostic criteria give two patterns, and only two. A cold can turn into a bacterial sinus infection when either one shows up.

Persistence. Symptoms last 10 days or longer with no evidence of improvement. Not “still lingering,” not “mostly better but annoying.” No improvement at all.

Double worsening. You were getting better, then got distinctly worse again — new fever, new facial pain, congestion that had loosened and then slammed shut. This typically lands around day five or six, after you’d already turned the corner.

The logic is simple. Viruses run a predictable arc: peak, then decline. A bacterial infection sitting in an obstructed, fluid-filled sinus doesn’t have to follow anyone’s arc, so it either flatlines or reverses course.

Practical version: write down the day your symptoms started, and note whether you had even one good day in between. That’s the first thing a physician will ask you.

If symptoms cross 12 weeks, you’ve left the acute question entirely — that’s the line between acute and chronic sinusitis.

Viral vs. bacterial sinusitis — and why most sinus infections are viral

Do you need antibiotics for a sinus infection? Usually, no. The CDC is direct about it: most sinus infections are viral and get better on their own. The literature puts true bacterial sinusitis at roughly 0.5% to 2% of upper respiratory infections in adults. Even among people who walk out of an appointment with an acute sinusitis diagnosis, only a minority have a bacterial infection.

Here’s the part that matters for bacterial versus viral sinusitis: they don’t have distinguishing symptoms. There’s no viral sinusitis vs bacterial sinusitis symptom that settles it at day four. Only the 10-day and double-worsening patterns do.

Antibiotics do nothing against a virus, and they aren’t free. GI upset, allergic reactions, C. diff, and resistance are all real costs. The 2025 AAO-HNS guideline update went further in this direction, extending watchful waiting as an initial option to all uncomplicated bacterial cases, regardless of severity.

Indiana Sinus Centers does not write antibiotics on request. Dr. Bichey’s question is why the sinuses aren’t draining, which is a different question from what’s growing in there. Repeat or long-term courses are their own conversation, and a different one from a single acute episode.

Sinus infection without a cold

Not every sinus infection starts with a virus. Some start with a drainage pathway that was already compromised: allergies, a deviated septum, a naturally narrow sinus opening, or an infected root in an upper tooth.

The tell is usually two-fold. No cold came first, and the pressure sits on one side.

Repeat infections that arrive without any cold in front of them are the pattern most likely to turn out anatomic. That’s a structural problem, not an infectious one, and it’s what an ENT is actually evaluating when chronic sinus problems get worked up.

What to do right now

Four questions. Answer them honestly and you’ll know where you stand.

Count the days since your symptoms started. Did you improve at any point and then get worse again? Is the pain concentrated on one side — one cheek, one eye, the upper teeth? Has a fever come back after it had already broken?

If the answer to all three is no and you’re under day 10, this is almost certainly still a cold, and it will run itself out.

If you said yes to any of the pattern questions, or if this is your third or fourth episode this year, it’s worth having evaluated.

Not sure where you land? Take the sinus quiz — it takes about two minutes and sorts cold from sinus infection using the same questions above.

The clock, not the symptoms

The symptoms won’t separate a cold from a sinus infection. Both give you congestion, pressure, drainage, and a headache. The clock separates them.

Ten days with no improvement, or a clear turn for the worse after you’d started getting better — those are the two patterns that mean anything. Everything else is noise, mucus color included.

Most sinus infections are viral and clear on their own. The ones worth a specialist’s time are the ones that keep coming back, or never fully clear.

If that’s your pattern, schedule an evaluation with Indiana Sinus Centers in Fort Wayne or Carmel. Dr. Bichey can tell you whether a drainage problem is what keeps putting you back in this position.

Frequently asked questions

How do I know if I have a sinus infection or just a cold?

Time is the clearest signal. A cold improves after day three to five. If your symptoms last 10 days or more with no improvement, or if you got better and then got noticeably worse again, a sinus infection is more likely.

Can a cold turn into a sinus infection?

Yes. A cold inflames the nasal lining and can block sinus drainage, and blocked sinuses can become infected. It usually shows up as symptoms that persist past 10 days, or a second wave of worsening after you’d already started improving.

Are most sinus infections bacterial?

No. Most acute sinus infections are viral and resolve on their own. Only a minority are bacterial, which is why antibiotics aren’t the automatic answer.

Do I need antibiotics for a sinus infection?

Only if it meets bacterial criteria: 10 or more days without improvement, or double worsening. Below that threshold, guidelines support watchful waiting rather than a prescription.

Can you get a sinus infection without a cold?

Yes. Blocked drainage from allergies, nasal anatomy, or an upper dental infection can cause sinusitis with no virus in front of it. Recurrent infections that arrive without a cold often point to a structural cause.
