# Ct Head: Cost, Coverage, and What to Expect Source: https://ourhealthnetwork.com/procedure-costs/ct-head Last reviewed: 2026-04-17 Data: CMS Hospital and Outpatient pricing, CPT/HCPCS code mapping ## Quick answer Medicare pays about $36 for the physician's professional fee on a CT head scan. The total bill patients see typically runs $300 to $1,500+ once the facility fee, radiologist reading, and setting (hospital vs freestanding) are included. ## What it is A CT scan of the head (also called a CT brain or cranial CT) is a fast imaging test that uses X-rays and a computer to build detailed cross-section pictures of your skull, brain, and surrounding tissue. It's one of the most common scans done in emergency rooms because it can spot bleeding, strokes, fractures, tumors, and swelling within minutes. The test itself takes less time than making a cup of coffee, but the bill behind it can take months to sort out. Here's what's involved in a typical CT head: - **Scan time:** The actual imaging takes 5 to 10 minutes, and the machine part is often under 60 seconds. - **Anesthesia:** None for most adults. Young children or claustrophobic patients sometimes get light sedation. - **Hospital stay:** None. CT heads are outpatient unless you're already admitted or came in through the ER. - **Contrast:** This specific code (70450) is **without contrast**. If your doctor orders contrast dye, it becomes a different billing code with a higher fee. - **Radiation exposure:** Roughly equivalent to 7 to 10 months of natural background radiation. Low-dose protocols exist, and you can ask about them. There's really only one common version of a non-contrast CT head billed to Medicare (HCPCS 70450). That keeps this page simple: one procedure, one code, but wildly different prices depending on *where* you get scanned. ## When it is done Most CT heads are ordered urgently or emergently, not as a routine check. Doctors use them when they need an answer fast, because CT is faster and more available than MRI and it's extremely good at catching the things that can't wait. Your doctor may recommend a CT head when: 1. You've had a significant head injury, fall, or car accident and they need to rule out a skull fracture or bleeding. 2. You're having sudden, severe headache symptoms, especially a "worst headache of your life" pattern. 3. You have stroke symptoms: sudden weakness, slurred speech, facial drooping, or vision changes. 4. You've had a seizure, especially a first-time seizure. 5. You have new, unexplained confusion, memory loss, or neurological changes. 6. They need to check for a brain tumor, hydrocephalus, or follow up on a known condition. MRI is often a better test for looking at soft tissue details, but MRI takes much longer, costs more, and isn't safe if you have certain implants. For anything urgent, CT is usually the first call. If your symptoms aren't emergent, it's worth asking your doctor whether MRI would be more informative before you book the CT. ## What you pay The CT head is one of the most mispriced procedures in healthcare. The Medicare physician fee is tiny (about $36 for the radiologist's interpretation), but the bill you'll actually receive depends almost entirely on where you got scanned and what your insurance does with the facility fee. For the exact same scan, the gap between a hospital outpatient CT head and a freestanding imaging center can easily top $1,000. **If you're on Medicare:** - Medicare covers CT head scans under **Part B** when medically necessary. - You'll typically pay **20% coinsurance** after your annual Part B deductible ($257 in 2025). - If the scan happens in a hospital outpatient department, expect both a facility charge and a physician charge on your bill. - A **Medigap** or **Medicare Advantage** plan can absorb most of the coinsurance; check your plan's out-of-pocket cap. **If you have commercial insurance:** - Most plans cover medically necessary CT heads, but prior authorization is increasingly common for non-emergency scans. - Expect to pay your deductible plus coinsurance. Out-of-pocket on a $1,200 hospital CT can be $200 to $800 depending on where you are in your deductible year. - Commercial negotiated rates typically run 2x-4x the Medicare rate for the total bill. - ER scans are almost always covered, but the facility and professional fees may land as separate bills. **If you're uninsured or paying cash:** - Independent imaging centers often post cash-pay prices of $150 to $500 for a CT head without contrast. - Hospital billing offices will usually **negotiate** if you ask; a 30-50% discount for prompt payment is common. - Ask for a bundled global fee that includes the technical and professional components so you don't get a second bill from the radiologist weeks later. - Hospital **charity care** programs can zero out the bill if your income is under a certain threshold, usually 200-400% of the federal poverty level. One important caveat on Medicare numbers: the $35.50 figure on this page is the physician's reading fee, not the total reimbursement for the scan. The hospital or imaging center also bills a separate technical/facility fee to Medicare, which is where most of the real money is. ## Anatomy of the bill A single CT head scan almost always generates at least two bills, sometimes three or more. This is where patients get blindsided. Understanding what each line item represents is the first step to catching errors or duplicate charges. **Facility fee (technical component):** This is the biggest line item. It covers the CT machine, the technologist running it, the room, supplies, and overhead. At a hospital outpatient department, this can be **$400 to $1,200**. At a freestanding imaging center, it's often **$150 to $400** for the same scan. **Professional interpretation fee:** The radiologist who reads the scan and writes the report bills separately. Medicare pays about **$35.50** for this. Commercial rates are typically **$75 to $200**. This bill often arrives weeks after the scan from a radiology group, not the hospital. **Contrast material:** Not applicable to this specific code (70450 is without contrast). If your scan ended up using contrast, it's a different code and adds **$50 to $300** for the dye plus injection. **Sedation:** Rare for CT heads in adults, but if it was used (typically for children or severely claustrophobic patients), expect a separate anesthesia bill of **$200 to $800**. **ER facility fee (if applicable):** If your CT was done in an emergency room, there's a separate ER visit fee on top of the scan. This is usually the largest charge on the whole bill, often **$1,000 to $3,000+** before insurance. Watch for duplicate professional fees (sometimes the hospital and the radiology group both bill for the read). Call and ask for an itemized bill, not a summary. ## Cost by state State-level Medicare data shows real geographic variation even on the small physician fee. Maryland tops the list at $48.83 per scan while West Virginia comes in cheapest at $28.38. California, Florida, Texas, and New York drive the highest total scan volumes, together accounting for over 10 million CT heads in the dataset. High-volume states don't necessarily mean lower prices; Maryland's above-average payment reflects its unique all-payer hospital rate system. Why costs vary so much by state: - **Medicare geographic adjustment (GPCI):** Medicare tweaks physician payments based on local practice costs, malpractice, and wages. That alone creates 40%+ variation between states. - **Commercial negotiation strength:** States with highly consolidated hospital systems (Massachusetts, New Jersey) often have higher commercial rates. States with stronger insurer leverage see lower negotiated prices. - **Cost of living and wages:** Radiology technologist pay and facility overhead vary dramatically from rural Mississippi to urban Northeast. - **State billing and transparency laws:** A handful of states (Colorado, Texas, Florida) require posted prices or have stronger surprise-billing protections, which shifts consumer behavior. ## Office vs facility Medicare data shows CT head scans are done overwhelmingly in **facility** settings (hospitals and their outpatient departments), with about 4.7 million services, versus roughly 200,000 done in office/freestanding settings. The per-scan Medicare payments look counterintuitive: office rates ($56.84) are higher than facility rates ($29.90). That's because the office rate bundles more of the work into a single payment, while facility billing splits it between the hospital and the physician. The real choice for most patients is **hospital outpatient department vs freestanding imaging center**, and here the total bill difference is dramatic. - **Hospital outpatient makes sense when:** the scan is part of an active ER or inpatient workup, your specialist is on that hospital's campus, or you need results instantly for urgent decision-making. - **Freestanding imaging center makes sense when:** the scan is routine or scheduled, cost matters, your insurance treats both settings the same, and your doctor is comfortable reviewing results electronically. - **Ask your doctor:** "Can I get this done at an outpatient imaging center instead of the hospital?" Nine times out of ten the answer is yes. It can save hundreds to over a thousand dollars. ## Who performs the procedure CT heads are performed by a radiology technologist and read by a diagnostic radiologist. The Medicare data is unambiguous: **diagnostic radiology** accounts for 19,374 providers and the overwhelming majority of reads, with a smaller tail of interventional radiologists, neurologists, and nuclear medicine physicians also billing CT head interpretations. You typically don't choose the radiologist who reads your scan; they're assigned by the imaging center or hospital. But you *can* choose where you get scanned, and that choice controls both cost and read quality. What to look for when choosing an imaging site: - **Accreditation:** Look for **ACR (American College of Radiology)** accreditation for the facility. It's a quality marker for equipment and protocols. - **Scanner generation:** A modern multi-detector CT (64-slice or better) gives faster scans with lower radiation. Older machines are still in use at smaller rural sites. - **Subspecialty reads:** For stroke, tumor follow-up, or complex cases, ask whether a **neuroradiology**-fellowship-trained reader will interpret the scan. Not every radiology group offers this. - **Turnaround time:** Emergency scans get read in under an hour. Routine outpatient reads can take 24-48 hours. Ask before you book if timing matters. - **Second opinion:** If the finding is significant (tumor, aneurysm, unusual bleeding), ask whether a subspecialist re-read is warranted before any surgical decision. The tiny provider counts in internal medicine, emergency medicine, and neurology (under 150 providers each) reflect physicians who occasionally bill for image review in their own clinics, not primary readers of CT scans. ## How to shop for the best price CT head scans are one of the easier procedures to comparison-shop because the scan itself is standardized and the results are portable. Here's the playbook: 1. **Request a Good Faith Estimate.** Federal law (No Surprises Act, 2022) requires providers to give uninsured or self-pay patients a written cost estimate on request. Get it in writing before you book. 2. **Verify every billing party is in-network.** This is the sneaky one. The imaging center might be in-network while the reading radiology group is not. Call your insurer and ask about both. 3. **Compare hospital vs freestanding imaging center.** Get at least two quotes for the same scan code (70450). Call the billing office directly and ask for the **cash-pay** or **negotiated self-pay** price, not the chargemaster price. 4. **Ask about bundled global pricing.** A bundled fee includes both the technical scan and the radiologist's read, so you don't get a second bill weeks later. This is standard at good freestanding centers. 5. **Use your insurer's cost estimator tool.** Most major commercial plans now have online tools that show in-network prices by facility. They're imperfect but often surface cheaper options you wouldn't have found otherwise. 6. **Ask about financial assistance or charity care.** Non-profit hospitals are legally required to offer charity care programs. Even for-profit systems usually have prompt-pay discounts of 30-50%. 7. **Confirm that results are portable.** You can request a copy of the images on disk or via secure transfer and share them with any doctor. You don't have to re-scan just to change providers. Red flags to watch for: vague estimates that exclude the professional read, billing offices that refuse to quote a price in writing, or hospitals that won't confirm in-network status for their contracted radiologists. If the front desk can't answer, escalate to the billing department before the scan happens. ## Surprise billing risks Imaging is a classic surprise-billing minefield. The scan itself is in-network, but the radiologist who reads it belongs to a different group, or a separate anesthesia provider bills for sedation nobody mentioned upfront. The No Surprises Act (2022) protects you in most of these situations, but only if you know to invoke it. **Most common surprise-billing sources on a CT head:** - **Out-of-network radiology group** at an in-network facility. This is the #1 surprise bill for imaging. The facility is in your network, but the radiologists who read the scans are a separate contracted group that isn't. - **ER facility fees** when a CT head is part of an emergency visit. Even if the ER is in-network, freestanding ER facility fees can be enormous. - **Separate anesthesia bill** if sedation was used (uncommon for CT heads but happens with kids or anxious adults). - **Balance billing on the facility fee** if the imaging center sends a bill for the difference between their charge and what your insurer paid. **If you get a surprise bill:** - Don't pay until you've verified the charge. Request an **itemized bill** with CPT/HCPCS codes. - If the bill is for out-of-network services at an in-network facility for an emergency, it's almost certainly protected under the **No Surprises Act**. File a complaint at **cms.gov/nosurprises**. - Contact your **state insurance commissioner** if the federal route doesn't resolve it; many states have stronger protections. - Ask for the **dispute resolution** process in writing. Providers are required to tell you how to appeal. ## Total recovery cost There's almost no recovery from a CT head scan itself. Most patients walk out of the imaging suite and drive home within 30 minutes. You can eat normally immediately, go back to work the same day, and resume all activities. The "total cost" for a CT head is really about follow-up, not recovery. **Add-on costs to budget for:** - **Follow-up visit with ordering doctor:** $100 to $300 commercial, or a copay. Your doctor needs to review the results with you; this is almost always billed separately. - **Additional imaging if findings are unclear:** An MRI follow-up after an equivocal CT is common and can add **$500 to $2,500+**. - **Subspecialist referral:** Neurology, neurosurgery, or oncology consults if the CT shows something abnormal. **$200 to $500+** per visit with insurance. - **Contrast allergy treatment:** Rare, but if you had an unexpected reaction, the ER visit and medications can run **$200 to $2,000**. - **Time off work:** Usually zero for the scan itself, but follow-up appointments may cost you half a day of wages. - **Transportation and parking:** Hospital parking alone can be $15 to $40. - **Disc copy or image transfer fee:** Some facilities charge $10 to $50 to release your images on disc or USB. For most patients, a routine CT head with normal findings ends up **5-10% more expensive** than the scan alone once you add in the follow-up visit and any minor add-ons. When findings are abnormal, total workup costs can quickly reach **3x-5x the scan price** once MRI, specialist consults, and potential biopsies or procedures get involved. ## Variants of this procedure - CT Head/Brain Without Contrast ## Frequently asked questions ### How much does a CT head cost with insurance? With commercial insurance, expect to pay between $100 and $800 out of pocket after your deductible and coinsurance. The range depends on where you are in your deductible year and whether you're scanned at a hospital or a freestanding center. Medicare enrollees typically owe 20% coinsurance after the Part B deductible ($257 in 2025). If you have supplemental coverage, your out-of-pocket can drop to almost nothing. ### Does Medicare cover CT scans of the head? Yes. Medicare Part B covers medically necessary CT head scans. You'll pay your annual Part B deductible plus 20% coinsurance of the Medicare-approved amount. The physician reading fee alone averages about $35.50 nationally, but Medicare also pays the facility separately for the technical component, which is the larger chunk of the total. ### How long does a CT head scan take and is there recovery? The scan itself is 5 to 10 minutes, with the actual imaging portion often under a minute. There's no recovery needed. You can drive, eat, and work immediately after. You don't need anesthesia unless you're severely claustrophobic or a young child. ### Is a CT head an outpatient test or do I need a hospital stay? CT heads are outpatient. You don't need to be admitted. The scan can be done at a hospital outpatient department, a freestanding imaging center, or during an ER visit. No overnight stay is required for the scan itself. ### How do I avoid a surprise bill on a CT head? Call your insurer and ask whether both the imaging facility AND the radiology group reading the scan are in-network. The radiology group is where most surprise bills originate. For non-emergency scans, request a Good Faith Estimate in writing. If you do get an unexpected bill from an out-of-network provider at an in-network facility, you're likely protected under the No Surprises Act (2022). ### What's the cheapest way to get a CT head scan? Freestanding imaging centers usually offer the best prices, often $150 to $500 cash-pay for a non-contrast head CT. Call three centers in your area, ask for the negotiated self-pay rate, and confirm the quote includes both the technical scan and the radiologist's interpretation. Hospital outpatient departments can be 2x-3x more expensive for the exact same scan. ### What's the difference between a CT head with and without contrast? This page covers CT head without contrast (HCPCS 70450), the most common version, used for trauma, stroke, and basic brain imaging. CT head with contrast uses IV dye to highlight blood vessels, tumors, or infections; it's a different billing code and costs $50 to $300 more. Your doctor chooses based on what they're looking for. ### Where does this cost data come from? Medicare payment figures on this page come from the CMS Medicare Physician and Other Practitioners Public Use File, which reports actual paid amounts for HCPCS 70450 across 21,092 providers and 4.9 million services nationally. Commercial, cash-pay, and out-of-pocket ranges are informed estimates based on industry norms, not direct CMS data.
