# External Beam Radiation: Cost, Coverage, and What to Expect Source: https://ourhealthnetwork.com/procedure-costs/external-beam-radiation Last reviewed: 2026-04-17 Data: CMS Hospital and Outpatient pricing, CPT/HCPCS code mapping ## Quick answer Medicare pays about $147 per billed service for radiation-therapy planning and management, but a full course of external beam radiation (IMRT or 3D conformal) typically totals $15,000 to $45,000 on Medicare and often two to four times that on commercial insurance, with the treatment technique and number of sessions driving most of the cost. ## What it is External beam radiation therapy (EBRT) aims high-energy X-rays or photons at a tumor from outside your body. A linear accelerator (linac) rotates around you and delivers shaped beams that kill cancer cells while sparing as much healthy tissue as possible. You lie still on a treatment table, the machine moves, and you feel nothing during the beam itself. Each session takes 10 to 30 minutes, most of which is setup. - **Consultation and staging:** one or two visits with a radiation oncologist before anything starts. - **Simulation:** a CT scan in the exact position you'll be treated in, often with small skin tattoos or a mold to keep you still. - **Treatment planning:** physicists and the oncologist design a beam plan on a computer. This takes several days. - **Delivery:** 15 to 44 daily sessions, Monday through Friday, over three to nine weeks. - **Weekly check-ins:** the oncologist reviews side effects and adjusts the plan. - **End-of-treatment and follow-up:** a final exam and imaging schedule. The two most common techniques on this page are **3D conformal radiation therapy (3D-CRT)** and **intensity-modulated radiation therapy (IMRT)**. 3D conformal shapes the beams to match the tumor. IMRT goes a step further by varying the intensity within each beam to spare nearby organs more precisely. IMRT is the more expensive technique and has become the default for prostate, head-and-neck, and many other cancers. Other variants on this page cover the planning, simulation, and physics work that supports both techniques. ## When it is done External beam radiation is a workhorse of cancer treatment. About half of all cancer patients receive radiation at some point. It's used to cure cancer, shrink tumors before surgery, clean up microscopic disease after surgery, and relieve pain from cancer that has spread to bones or the brain. Your doctor may recommend this when: 1. You have an early-stage prostate, breast, lung, or head-and-neck cancer where radiation is curative and avoids surgery. 2. You've had surgery for breast or colorectal cancer and need adjuvant radiation to lower the chance of recurrence. 3. You have a tumor that's inoperable because of location (near the spinal cord or brainstem) or because surgery would be too risky. 4. Cancer has spread to bones or the brain and radiation can shrink the tumor to reduce pain or pressure (palliative radiation). 5. You have lymphoma, anal cancer, or cervical cancer where radiation combined with chemotherapy is standard. 6. A tumor needs to be shrunk before surgery (neoadjuvant) to make the operation easier. Alternatives depend on your cancer. Stereotactic radiosurgery (SRS/SBRT) delivers much higher doses in 1 to 5 sessions for small tumors. Proton beam therapy uses charged particles instead of photons and costs significantly more. Brachytherapy puts radiation sources directly inside or next to the tumor. For some cancers, surgery, chemotherapy alone, or active surveillance are reasonable options. The right choice depends on tumor type, stage, your age, and side-effect priorities. ## What you pay Radiation therapy billing is confusing because there is no single charge. A full course is a stack of 30 to 50 separate line items for consultation, simulation, planning, physics, device construction, weekly management, and individual treatment delivery. The codes on this page cover planning and management only. Daily beam delivery is billed under separate codes (77385/77386 for IMRT, 77402-77412 for 3D conformal) and adds several hundred to over a thousand dollars per session on commercial plans. Medicare generally pays 40% to 55% of commercial rates for the same services. **If you're on Medicare:** - Radiation is almost always outpatient, so it's covered under **Part B**, not Part A. You'll pay the $257 Part B deductible (2025 figure) once for the year, then 20% coinsurance on every service. - With no supplemental coverage, a full IMRT course can leave you owing $3,000 to $8,000 out of pocket in coinsurance. - A **Medigap** plan typically covers that 20%, leaving you with little or nothing. - **Medicare Advantage** plans vary: some require prior authorization for IMRT and cap out-of-pocket at the plan's annual maximum (often $4,000 to $8,900 in 2025). **If you have commercial insurance:** - Expect the full course to bill $30,000 to $150,000 depending on technique and location. Employer plans negotiate this down significantly. - You'll hit your annual **deductible** within the first week or two of treatment, then pay coinsurance (usually 20% to 30%) until you hit the **out-of-pocket maximum**, which ACA plans cap at $9,200 individual / $18,400 family for 2025. - Realistic patient responsibility for a full course: **$3,000 to $9,200** in most cases, because almost everyone hits their OOP max. - **Prior authorization is required** by most plans for IMRT and proton therapy. Denials are common. Your radiation oncologist's office handles this. **If you're uninsured or paying cash:** - Freestanding radiation centers often quote bundled cash-pay rates of **$12,000 to $35,000 for a full course of 3D conformal** and **$25,000 to $60,000 for IMRT**. Hospital-based pricing runs higher. - Many cancer centers have **charity-care** programs that reduce or eliminate cost if you're below 200% to 400% of the federal poverty level. - Drug-company and foundation grants (CancerCare, Patient Advocate Foundation, HealthWell) help with copays and transportation but usually not the bulk of treatment cost. - Negotiating a lump-sum discount of 20% to 40% is realistic if you can pay upfront or commit to a payment plan. ## Anatomy of the bill A full radiation course generates one of the longest bills in medicine. Understanding the pieces helps you spot errors and plan ahead. - **Radiation oncologist consultation fee:** billed by the physician, typically $200 to $500 for the initial visit. Covered like any specialist visit. - **Simulation (CT planning scan):** $150 to $800 depending on whether it's a simple (77280) or complex (77290) simulation. Respiratory gating (77293) adds another line. - **Treatment planning:** the largest single planning charge. **3D conformal planning (77295)** averages $222 on Medicare. **IMRT planning (77301)** averages $628 on Medicare and is often billed over $3,000 by hospitals. This is where technique choice drives the biggest dollar difference. - **Treatment device construction:** $60 to $230 per device on Medicare. IMRT uses 77338; standard devices use 77334. - **Physics consultation, weekly:** about $69 per week on Medicare (77336), covering the medical physicist's calibration and dose-verification work. - **Weekly treatment management:** about $152 per 5 treatments on Medicare (77427), billed by the radiation oncologist to cover ongoing oversight. - **Daily beam delivery:** NOT in the codes on this page. Delivery is billed under separate codes and is where most of the total dollars live. Medicare pays roughly $150 to $500 per fraction depending on technique and setting; commercial plans often pay $500 to $2,000 per fraction. - **Image guidance (IGRT):** often a separate line charge for the daily cone-beam CT that verifies tumor position before the beam turns on. - **Follow-up imaging and exams:** first follow-up usually 4 to 12 weeks after treatment ends, billed like any office visit. ## Cost by state State-level Medicare payment for planning and management codes ranges from $114 in **South Dakota** to $206 in **Alaska**, a 1.8x spread. High-volume states lean higher: California averages $176, Florida $160, and New York $159, while many rural states cluster in the $115 to $135 range. Florida, California, and Texas together account for more than two million of the 3.2 million services in the data, reflecting both population and high cancer-treatment volumes in those states. Keep in mind these state figures cover physician reimbursement only. Facility fees and beam delivery are billed separately and vary just as much. **Why costs vary by state:** - **Medicare geographic adjustments (GPCI):** Medicare multiplies base rates by local practice-cost and wage indexes. Alaska, Hawaii, and urban coastal markets hit the top. - **Commercial negotiation power:** a few hospital systems dominate regional markets, pushing commercial rates far above Medicare. States with stronger insurer competition see narrower gaps. - **Cost of living and labor:** radiation therapists, physicists, and oncologists earn more in high-cost metros, and that flows into facility fees. - **State balance-billing laws:** states like New York, California, and Texas have layered protections on top of the federal No Surprises Act that affect what ancillary providers can charge you. ## Office vs facility Unlike most procedures, radiation therapy splits almost evenly between settings. Medicare data shows 1.8 million services in office (freestanding) settings versus 1.4 million in facility (hospital outpatient) settings. The financial gap is large: Medicare pays an average of **$267 per service in office settings** versus **$139 in facility settings**. That's because freestanding centers get paid a single global fee that covers both the physician and the equipment, while hospital outpatient departments bill separately for facility and professional services. The hospital total often ends up higher for commercial patients even though the Medicare physician component looks lower. **When a hospital-based center makes more sense:** - You have a complex cancer that benefits from an on-site multidisciplinary team. - You're already receiving chemotherapy or surgery at the same system. - Your insurance contract gives you a better deal in-network at the hospital. **When a freestanding center makes more sense:** - Your treatment is straightforward (breast adjuvant, palliative, prostate). - You're paying cash or have a high-deductible plan (bundled pricing is usually lower). - You want shorter wait times and simpler scheduling. ## Who performs the procedure Radiation oncology dominates this procedure. Of 4,720 providers in Medicare data, **4,619 (98%)** are radiation oncologists. They spend 4 to 5 years in specialized residency learning beam physics, treatment planning, and cancer management. Dermatology shows 376 providers but almost exclusively for superficial skin-cancer radiation (a narrow subset, often using a different type of machine). Diagnostic radiology shows 49 providers, a tiny sliver usually reflecting joint interpretation of planning scans rather than treatment delivery. **What to look for when choosing a radiation oncologist:** - **Board certification in radiation oncology** through the American Board of Radiology. - **Volume and focus in your cancer type.** A high-volume prostate center or head-and-neck specialist typically delivers better outcomes for those diseases. - **Access to modern technology:** IMRT, image guidance (IGRT), SBRT, and increasingly adaptive radiotherapy. Ask what linac platform they use. - **Integration with the rest of your cancer team.** Tumor boards, multidisciplinary clinics, and shared electronic records reduce errors. - **A second opinion before committing,** especially for prostate, breast, or head-and-neck cases where the technique choice (3D vs IMRT vs proton vs SBRT vs surgery) genuinely changes long-term side effects. - **NCI-designated cancer center affiliation** if your case is complex or rare. These centers treat more patients, participate in trials, and often coordinate care better. Note on non-radiation-oncology specialties listed: if your bill shows services from a specialty other than radiation oncology, it almost always reflects a supporting role. Dermatology handles superficial skin lesions; diagnostic radiology handles imaging interpretation, not primary treatment. ## How to shop for the best price Radiation is one of the more shoppable cancer treatments because the treatment plan is built over several days, giving you time to compare options before anything starts. Use that window. 1. **Request a Good Faith Estimate in writing.** Federal law requires hospitals and freestanding radiation centers to give uninsured and self-pay patients a written cost estimate within 3 business days. Ask for a line-by-line breakdown including planning, delivery, physics, and management. 2. **Verify in-network status for every entity.** Radiation bills commonly involve the physician, the facility, a separate physics group, and sometimes an imaging center for the planning scan. Confirm every one is in-network with your plan. 3. **Compare hospital outpatient versus freestanding.** Get quotes from both. Bundled freestanding pricing is often 30% to 50% lower for identical treatment. Quality at accredited freestanding centers is generally comparable for common cancers. 4. **Ask whether shorter courses (hypofractionation) are appropriate.** For prostate, breast, and palliative cases, 5 to 15 sessions may replace 25 to 44 sessions with equivalent outcomes. Fewer fractions means lower total cost. 5. **Get a second opinion on technique.** IMRT costs far more than 3D conformal. For some cancers (breast, palliative) 3D conformal is clinically equivalent. Proton therapy costs even more and is rarely necessary outside pediatric or specific adult cases. 6. **Ask about financial assistance upfront.** Hospital charity care, drug-company assistance, CancerCare, Patient Advocate Foundation, and the HealthWell Foundation all help with cancer-treatment costs. Apply before the bills arrive. 7. **Negotiate for cash-pay or upfront payment.** A 20% to 40% lump-sum discount is often available if you commit before treatment starts. Red flags: any provider who won't give you a written estimate, any quote that doesn't itemize planning versus delivery, and any mention of "we'll sort out cost later." Radiation billing is too complex to leave unresolved. ## Surprise billing risks Most radiation surprise bills come from the **ancillary services bundled into the course** rather than the treatment itself. Patients routinely assume the radiation oncologist's quote covers everything, then receive unexpected bills from physicists, pathologists (if biopsies were reviewed), imaging centers, and out-of-network facility fees. **Most common surprise-billing sources:** - **Planning CT scan billed by an out-of-network imaging center** even when the radiation oncologist is in-network. - **Hospital facility fees** added on top of the physician quote when you chose a hospital-outpatient center. - **Pathology review fees** if the radiation oncologist re-reviews your biopsy slides with an outside pathologist. - **Separately-billed medical physics group** that isn't employed by the radiation center. - **Repeat simulations or re-planning** if your anatomy changes mid-course (weight loss, tumor response). **If you get a surprise bill:** - **Do not pay until you verify.** Request a fully itemized bill with every CPT code. - **Compare to your Explanation of Benefits (EOB)** from your insurer. Flag anything the EOB doesn't reference. - **Invoke the federal No Surprises Act of 2022** for any emergency or unanticipated out-of-network charge from a facility where your primary provider was in-network. File a complaint at cms.gov/nosurprises. - **Escalate to your state insurance commissioner** for state-regulated plans if the NSA doesn't apply. ## Total recovery cost Most radiation patients continue working and living normally throughout treatment. Side effects are usually mild in the first two weeks and build gradually: fatigue, skin changes in the treated area, and organ-specific effects (dry mouth for head-neck, bowel/bladder irritation for pelvic). Most effects peak at the end of treatment and resolve over 2 to 8 weeks after the last session. **Add-on costs to budget for:** - **Transportation:** 15 to 44 daily trips add up. Budget $5 to $30 per round trip in fuel plus parking. Many cancer centers offer transportation assistance or ride-share vouchers. - **Time off work:** most people work through treatment but need to leave an hour early for appointments. Physically demanding jobs may need modified duty. Estimate 30 to 100 hours of reduced productivity over the course. - **Skin-care supplies:** prescribed creams and gentle cleansers, roughly $50 to $200 out of pocket. - **Anti-nausea or diarrhea medications:** $20 to $150 depending on insurance coverage. - **Nutritional supplements** (common for head-neck or abdominal radiation): $100 to $500. - **Dental work before head-neck radiation:** pre-treatment extractions and fluoride trays often cost $500 to $3,000 and are rarely fully covered. - **Follow-up imaging** in the first year: one or two scans at $300 to $2,000 each after insurance. Expect the total episode cost, including follow-up, side-effect management, and lost productivity, to run **15% to 30% higher than the sticker price** for the radiation itself. For a Medicare patient on a $25,000 IMRT course, realistic all-in cost is closer to $30,000 once ancillary services and lost work are counted. ## Variants of this procedure - Complex Treatment Planning - Basic Simulation - Complex Simulation - Respiratory Gating Setup - 3D Conformal Treatment Plan - IMRT Treatment Plan - Advanced External Beam Plan - Standard Treatment Device - Weekly Physics Check - IMRT Treatment Device - Weekly Treatment Management ## Frequently asked questions ### How much does radiation therapy cost with insurance? Most commercially insured patients end up paying between $3,000 and $9,200 out of pocket for a full course, because treatment almost always pushes you past your annual deductible and into your plan's out-of-pocket maximum. ACA-compliant plans cap 2025 out-of-pocket at $9,200 individual. Medicare patients with supplemental coverage often pay little or nothing beyond premiums. ### Does Medicare cover external beam radiation therapy? Yes. Radiation therapy is covered under **Medicare Part B** when delivered as an outpatient, which is standard. You'll owe the Part B deductible ($257 in 2025) plus 20% coinsurance on each service. Medigap or a Medicare Advantage out-of-pocket cap usually limits your total exposure. Prior authorization is required for IMRT under most Medicare Advantage plans. ### How long is a typical course of radiation? Most curative courses run 3 to 9 weeks with daily sessions Monday through Friday. Common lengths: 15 to 20 fractions for breast, 20 to 28 for hypofractionated prostate, 28 to 35 for head-neck, and 1 to 10 for palliative bone or brain radiation. Each session takes 10 to 30 minutes. ### Is radiation therapy outpatient? Yes, almost always. External beam radiation is delivered in a linear accelerator vault and you go home the same day. You don't need anesthesia or an overnight stay. This is why radiation is billed under Medicare Part B (outpatient), not Part A (inpatient). ### What's the difference between IMRT and 3D conformal radiation? **3D conformal radiation (3D-CRT)** uses shaped beams that match the tumor outline and deliver uniform dose. **IMRT** goes further by modulating the intensity within each beam to shape the dose around nearby organs, reducing side effects for prostate, head-neck, and similar cancers. IMRT planning is technically harder and the Medicare fee schedule pays the IMRT planning code (77301) about 3 times more than the 3D planning code (77295) because of higher work and practice RVUs. For some cancers (breast, palliative), 3D conformal is equally effective and costs much less. ### How do I avoid a surprise bill during radiation treatment? Verify that the physician, facility, physics group, and imaging center are all in-network before simulation. Request a written Good Faith Estimate. Keep every Explanation of Benefits and match it against itemized bills. If a charge doesn't match your EOB, don't pay until it's reconciled. The No Surprises Act protects you from most out-of-network charges at in-network facilities. ### What's the cheapest way to get radiation therapy? Freestanding radiation centers with bundled cash-pay rates typically cost 30% to 50% less than hospital outpatient departments for the same treatment. Ask about **hypofractionation** (shorter courses) where clinically appropriate, since fewer sessions means lower total cost. Apply for hospital charity care and foundation grants before treatment starts. Get a second opinion comparing IMRT, 3D conformal, SBRT, and surgery where your cancer allows choice. ### Where does this cost data come from? The Medicare figures on this page come from the CMS Medicare Physician & Other Practitioners public-use file, which reports national and state-level averages for charges, allowed amounts, and payments across all Part B radiation therapy planning and management codes. Commercial and cash figures are industry ranges and should be confirmed with a written estimate from the provider you plan to use. ## Related - [All procedure cost concepts](https://ourhealthnetwork.com/procedure-costs) - [Find specialists who perform this procedure](https://ourhealthnetwork.com/find-doctors) - [Insurance plans that cover this procedure](https://ourhealthnetwork.com/tools/insurance-matcher)
