## Quick answer

Medicare pays about $713 to the surgeon for carotid artery surgery, but the full hospital episode including facility, anesthesia, and recovery typically runs $20,000 to $45,000 on commercial insurance.

## What it is

Carotid artery surgery treats dangerous narrowing of the carotid arteries, the two large vessels in your neck that feed blood to your brain. When plaque builds up inside these arteries, pieces can break off and travel to the brain, causing a stroke. The goal of surgery is to remove or bypass the narrowing before that happens.

There are two main procedures, and they work very differently:

- **Procedure time:** 1 to 2.5 hours for open endarterectomy; 1 to 2 hours for stenting
- **Anesthesia:** General anesthesia is common for open surgery. Stenting is typically done with local anesthesia and sedation.
- **Hospital stay:** Most patients stay 1 to 3 days, often starting in a step-down or ICU bed for overnight monitoring
- **Incision:** Open surgery uses a 3 to 4 inch incision along the side of your neck. Stenting uses a small puncture in the groin or wrist, no neck incision.
- **Blood loss:** Minimal for both approaches

The two variants in our data are carotid endarterectomy (CPT 35301) and carotid artery stenting (CPT 37215). Endarterectomy is open surgery: the surgeon physically opens the artery and scrapes out the plaque. Stenting threads a thin catheter from the groin, placing a metal mesh stent to prop the artery open. Both aim to prevent stroke. The right one depends on your anatomy, age, symptoms, and surgical risk.

## When it is done

Carotid surgery is not offered to everyone with narrowing. It is offered when the benefit of preventing a stroke clearly outweighs the roughly 2 to 5% risk of causing one during surgery. That math depends on how narrow the artery is and whether you have already had warning symptoms.

Your doctor may recommend this when:

1. You had a stroke or TIA (mini-stroke) and imaging shows 50% or greater narrowing of the carotid on the same side
2. You have no symptoms, but imaging shows 70% or greater narrowing and you are otherwise healthy enough to benefit
3. Medical therapy alone (statins, antiplatelet drugs, blood pressure control) has not stabilized your carotid disease
4. Your plaque shows high-risk features on imaging, such as ulceration or hemorrhage inside the plaque
5. You are scheduled for major heart surgery and severe carotid disease was found during pre-op workup

For patients with less than 50% narrowing, medical therapy is almost always the answer. Statins, aspirin or clopidogrel, and aggressive blood pressure and diabetes control can be as effective as surgery for borderline cases. A second opinion from a stroke neurologist is reasonable before committing to either procedure, especially if you have no symptoms.

## What you pay

The Medicare numbers you see for carotid surgery ($713 on average) are just the surgeon's professional fee. They are not the bill. The facility fee, anesthesia, pre-op imaging, and any ICU time are billed separately and make up the bulk of what you or your insurance actually pay. On commercial insurance, the total hospital bill for carotid endarterectomy or stenting typically runs $20,000 to $45,000 before any discounts. Medicare's total spend, including Part A hospital stay and Part B professional fees, is roughly 40 to 55% of that.

**If you're on Medicare:**

- Carotid surgery is almost always billed as an inpatient admission, which triggers Part A
- Expect the $1,676 Part A inpatient deductible (2025 figure) for your hospital stay, assuming a stay under 60 days
- Part B covers 80% of the surgeon and anesthesia fees after the $257 annual Part B deductible (2025 figure); you pay 20% coinsurance
- A Medigap or Medicare Advantage plan can reduce or eliminate that 20% out-of-pocket piece

**If you have commercial insurance:**

- Expect to hit your full deductible, often $2,000 to $8,000 depending on the plan
- After deductible, coinsurance (usually 10 to 30%) applies until you reach your out-of-pocket maximum
- Most patients end up paying somewhere between their deductible and their out-of-pocket max, so budgeting the full OOP max for the year is realistic
- In-network status of the surgeon, hospital, AND anesthesiologist all matter. A single out-of-network provider can blow up the bill.

**If you're uninsured or paying cash:**

- Ask for the hospital's cash-pay or self-pay discount up front; this often cuts the bill 40 to 60%
- Some centers offer bundled cash-pay pricing for carotid endarterectomy in the $15,000 to $25,000 range, more for stenting due to device cost
- Nonprofit hospitals are legally required to have a financial assistance (charity care) policy; ask for the application
- Negotiate in writing before the procedure, not after. Once the bill is generated, leverage drops.

## Anatomy of the bill

A carotid surgery bill is not one invoice. It is a stack of separate charges from different entities, all for the same hospital stay. The Medicare data ($713 average) only reflects the surgeon's slice.

**Surgeon fee:** The vascular or general surgeon performing the procedure. Medicare averages $708 for endarterectomy and $723 for stenting. Commercial pays roughly 2 to 3x that.

**Facility fee (hospital):** By far the largest line item. Covers the operating room, nursing, supplies, and your hospital room. On Medicare, this is bundled into the DRG payment. On commercial, facility fees for carotid surgery frequently run $15,000 to $30,000 billed.

**Anesthesia:** Billed by the anesthesiologist or CRNA separately. Medicare pays $400 to $800; commercial runs $1,500 to $3,500. Anesthesia groups are a common out-of-network trap.

**Device/stent:** For carotid stenting only. The stent and embolic protection filter together can cost the hospital $2,000 to $5,000, passed through on the facility bill.

**Pre-op imaging:** Carotid ultrasound, CT angiography (CTA), or MR angiography (MRA) billed by the radiology practice. $300 to $2,000 depending on the study.

**ICU or step-down bed:** Most patients spend the first night in a monitored unit. This adds a per-day facility charge of $2,500 to $5,000 on commercial.

**Pathology:** Plaque removed during endarterectomy is usually sent to pathology for review. Small but separately billed, $100 to $400.

**Post-op follow-up:** A wound check visit plus a follow-up carotid ultrasound at 1 to 3 months, each billed under Part B.

## Cost by state

Medicare surgeon fees for carotid surgery range from $450 in Idaho to $874 in Washington, DC, nearly double. Texas, Florida, and California do the most procedures by volume, together accounting for over 40% of national carotid surgery claims. Nebraska, Virginia, and Georgia also punch above their weight. The priciest states for the surgeon fee tend to be urban, coastal, or both, reflecting the Medicare Geographic Practice Cost Index.

These state differences cover only the physician's fee. Total episode cost variation across states (facility, anesthesia, implant) is far larger, often 3 to 5x between the cheapest and priciest regions.

Why costs vary by state:

- **Medicare GPCI:** Federal geographic adjustments raise physician fees in high-cost metros and lower them in rural areas
- **Commercial negotiation:** Hospital systems in concentrated markets (one or two dominant systems) command higher commercial rates than competitive markets
- **State billing laws:** Some states have stronger surprise-billing protections and price transparency rules that compress outlier charges
- **Local cost of living:** Labor costs for nursing, OR staff, and anesthesia drive facility pricing regionally

## Office vs facility

Carotid artery surgery is essentially never done in an office setting. Medicare data shows 18,441 services billed in facility settings and effectively none in office settings, because both open endarterectomy and stenting require an operating room, general or deep sedation, and inpatient-level monitoring afterward. The real choice for patients is what kind of facility.

The practical decision is hospital with an ICU versus a hospital without. Ambulatory surgery centers do not do carotid surgery.

When a major academic or high-volume hospital makes sense:

- You are a high-risk patient (prior stroke, severe heart disease, complex anatomy)
- Stenting is being considered, since device centers need the full endovascular suite and experienced operators
- You want access to both open and endovascular options under one roof

When a community hospital can be appropriate:

- You are a lower-risk patient with straightforward anatomy
- The hospital has a vascular surgeon with documented volume (at least 20 carotids per year)
- The 30-day stroke/death rate is at or below benchmark (typically under 3% for asymptomatic patients, under 6% for symptomatic)

## Who performs the procedure

Vascular surgeons perform the large majority of carotid surgeries in the United States. Medicare data shows 545 vascular surgeons doing carotid procedures, with general surgery, thoracic surgery, and cardiac surgery splitting most of the remainder. Vascular surgeons average the highest volumes per provider, which matters: stroke and death rates for carotid surgery drop meaningfully at higher-volume centers and with higher-volume surgeons.

What to look for when choosing a specialist:

- **Volume:** Ask how many carotid procedures the surgeon and the hospital do per year. Guidelines suggest at least 20 per year for individual surgeons.
- **Focus:** A vascular surgeon who does carotid work weekly is different from a general surgeon who does a few per year
- **Complication rates:** Hospitals with active quality reporting (SVS Vascular Quality Initiative, for example) should be willing to share their 30-day stroke and death rates
- **Both options available:** Centers that offer both open endarterectomy and stenting can recommend the better fit for your anatomy rather than defaulting to what they do
- **Board certification:** Board certification in vascular surgery (or general surgery with vascular fellowship) is the standard
- **Second opinion threshold:** If symptoms are borderline or narrowing is under 70% without symptoms, get a stroke neurologist's opinion on medical management first

You will also see physician assistants listed in billing data with a much lower average payment ($113) and high service counts. That reflects assistant-at-surgery roles and post-op rounding, not primary surgeons. A PA is not performing your carotid procedure.

## How to shop for the best price

Carotid surgery is not a procedure you shop for like a knee MRI, but you have more leverage than most patients realize, especially on the cost side.

1. **Request a Good Faith Estimate in writing.** Federal law (No Surprises Act) requires hospitals to provide one to uninsured and self-pay patients, and most will for insured patients if you ask. Get it before you schedule.
2. **Verify every billing party is in-network.** The surgeon, the hospital, the anesthesia group, the radiologist reading your pre-op imaging, and the pathologist reviewing your plaque can all bill separately. One out-of-network entity can cost thousands.
3. **Ask whether the hospital offers a bundled or global case rate.** Some systems quote a single all-in price for carotid surgery, which is easier to compare and harder to surprise-bill.
4. **Compare two hospitals.** A high-volume center 45 minutes farther away may be safer AND cheaper than the nearest one. Get GFEs from both.
5. **Ask about payment plans and charity care.** Nonprofit hospitals must offer financial assistance. Even commercial insurance patients may qualify for reduced out-of-pocket through hospital aid programs.
6. **Get a second opinion on medical management.** Especially if you are asymptomatic with borderline narrowing, a stroke neurologist can tell you whether surgery is truly indicated. Avoiding the procedure entirely is the cheapest option.
7. **For stenting, ask about device choice.** Different stents and protection devices have different costs. Hospitals rarely volunteer this, but surgeons can often use a mid-cost device that performs equivalently.

Red flags: any provider who will not give you an estimate in writing, vague answers about which anesthesia group is being used, or pressure to proceed urgently when symptoms are absent. Asymptomatic carotid disease rarely requires same-week surgery.

## Surprise billing risks

Carotid surgery is a classic source of surprise bills because the charges come from so many different providers and facilities. Even with in-network surgeons and hospitals, ancillary providers (anesthesia, radiology, pathology) often slip through in a different network tier. The No Surprises Act of 2022 protects you from most out-of-network emergency and facility-based charges for in-network hospital stays, but enforcement requires you to know when to push back.

Most common surprise-billing sources for carotid surgery:

- **Anesthesiologist or CRNA:** The hospital is in-network but the anesthesia group contracts separately
- **Radiologist interpreting pre-op CTA or MRA:** Often a separate reading group
- **Pathologist reviewing removed plaque:** Same issue
- **Assistant surgeon or surgical PA:** Sometimes billed as a separate out-of-network provider
- **Post-discharge follow-up imaging:** Carotid ultrasounds done at outpatient clinics can land with a different contract than the hospital

If you get a surprise bill:

- Do not pay immediately. Request a fully itemized bill and match every line to your explanation of benefits
- If the charge falls under the No Surprises Act, submit a dispute through cms.gov/nosurprises or call 1-800-985-3059
- File a complaint with your state insurance commissioner for state-regulated plans
- Ask the hospital's patient advocate or financial counselor to rebill in-network; this works more often than patients expect

## Total recovery cost

Most patients leave the hospital 1 to 2 days after carotid endarterectomy and the same day or the morning after carotid stenting. The first 2 weeks are mostly rest and wound care for open surgery, or just groin puncture care for stenting. Expect to avoid heavy lifting for 2 to 4 weeks, and most desk-job patients are back to work within 1 to 2 weeks. Driving typically resumes in 1 to 2 weeks, once neck range of motion returns and you are off narcotic pain medication.

Add-on costs to budget for:

- **Follow-up carotid ultrasound (1 to 3 months post-op):** $200 to $700 on commercial; Medicare covers about 80% after deductible
- **Antiplatelet drugs:** Aspirin and often clopidogrel (Plavix) for 30 to 90 days after stenting, $10 to $80 per month
- **Statin therapy (lifelong for most patients):** Generic rosuvastatin or atorvastatin, $5 to $20 per month
- **Pain medication:** Short-course opioids and ibuprofen, $20 to $100
- **Time off work:** 1 to 3 weeks for desk jobs, 4 to 6 weeks for physical work; factor lost wages
- **Transportation help:** You cannot drive for the first week or two
- **Smoking cessation or cardiac rehab:** Often recommended, variable cost and insurance coverage

All in, the true episode cost, including follow-up imaging, medications for the first year, and missed work, typically adds 10 to 20% on top of the sticker price of the procedure itself. Patients who budget only for the hospital bill and the surgeon often get caught off-guard by the string of smaller follow-up charges.

## Frequently asked questions

### How much does carotid artery surgery cost with insurance?

On commercial insurance, expect to pay somewhere between your deductible and your out-of-pocket maximum, commonly $2,000 to $8,000. The billed hospital total is usually $20,000 to $45,000, but insurance covers most of that after deductible and coinsurance. Your exact cost depends on your plan and whether every provider (surgeon, hospital, anesthesia) is in-network.

### Does Medicare cover carotid endarterectomy and carotid stenting?

Yes. Medicare covers carotid endarterectomy (CPT 35301) broadly when clinically indicated. Carotid stenting (CPT 37215) is covered for specific higher-risk patients, including those with significant stenosis who are poor surgical candidates or have unfavorable neck anatomy. You pay the Part A inpatient deductible ($1,676 in 2025) plus Part B coinsurance unless you have supplemental coverage.

### How long is recovery from carotid surgery?

Most patients go home 1 to 2 days after open endarterectomy and the same day or next morning after stenting. Light activity resumes in a few days, heavy lifting in 2 to 4 weeks, and most desk workers return to work within 1 to 2 weeks. Full recovery including any wound healing and follow-up imaging takes about 1 to 3 months.

### Is carotid surgery outpatient or does it require a hospital stay?

It is almost always an inpatient hospital stay, typically 1 to 3 days. Even stenting, which is less invasive, usually requires at least overnight monitoring for blood pressure control and neurological checks. This is not an ambulatory surgery center procedure.

### What's the difference between carotid endarterectomy and carotid stenting?

Endarterectomy is open surgery: the surgeon opens the artery through a neck incision and physically removes the plaque. Stenting is endovascular: a catheter is threaded from the groin and a metal mesh stent is placed to hold the artery open. Endarterectomy is the long-standing gold standard, while stenting is preferred for patients with hostile neck anatomy, prior neck radiation, or very high cardiac risk. Medicare pays slightly more for stenting because of the device delivery, imaging, and embolic protection work involved.

### How do I avoid a surprise bill for carotid surgery?

Request a Good Faith Estimate before scheduling, verify in-network status for the surgeon, the hospital, AND the anesthesia group, and ask specifically about radiology and pathology billing. After surgery, match every bill to your explanation of benefits. If something looks out-of-network at an in-network facility, the No Surprises Act likely protects you. Dispute through cms.gov/nosurprises.

### What's the cheapest way to get carotid artery surgery?

First, confirm you actually need it; a stroke neurologist's opinion on medical management may avoid surgery entirely for asymptomatic borderline cases. If surgery is indicated, shop among in-network high-volume hospitals, ask for a bundled case rate, negotiate self-pay discounts if uninsured, and apply for hospital charity care if eligible. Community hospitals with documented vascular-surgery volume can be both safer and cheaper than academic centers for straightforward cases.

### Where does this cost data come from?

The Medicare figures come from the CMS Medicare Physician & Other Practitioners by Provider and Service dataset, reflecting actual paid amounts for CPT codes 35301 and 37215 across the United States. These are the surgeon's professional fees only and do not include the facility fee, anesthesia, or device costs. Commercial and cash-pay ranges are industry-reported ranges and will vary widely by region and plan.
