Book a Free Consultation Today!Many radiation oncology practices believe Medicare has already shifted to an episode-based payment model. That isn’t the case. The disconnect between expectations and the actual regulations is where practices are losing revenue in 2026. Teams are preparing for a reimbursement model that has not been implemented while continuing to bill under a coding structure that changed on January 1, 2026.
Here’s what is in effect today, what is still under consideration, and what your practice should do in response.
Radiation oncology continues to be reimbursed under the traditional Medicare fee-for-service model in 2026. No Medicare episode-based payment system currently applies to the specialty. The proposed Radiation Oncology Model was never launched, and the Radiation Oncology Case Rate (ROCR) Value Based Program Act (S.1031 / H.R.2120) is still pending before Congress. The most significant change for 2026 is the consolidation of treatment delivery codes into 77402, 77407, and 77412, along with a 2.5% efficiency adjustment applied to work RVUs.

The Medicare episode model for radiation oncology doesn’t exist
CMS invested years in developing the Radiation Oncology Model, but it never became operational. The proposed model included payment reductions that many providers believed would limit patient access, along with reporting requirements practices considered difficult to manage. After several delays, the initiative was ultimately put on hold and has remained inactive.
As a result, radiation oncology finds itself in an unusual position. For years, practices have anticipated an upcoming bundled payment model, yet billing departments continue submitting fee-for-service claims for each treatment fraction, just as they did years ago.
This misunderstanding creates real financial consequences. Many organizations postpone updating their charge masters because they assume a new payment model is imminent. However, coding requirements continue to evolve, and delaying those updates often results in urgent and costly billing corrections later.
If your organization has been waiting for an episode-based payment system before improving billing operations, now is the time to move forward. Fee-for-service remains the current Medicare reimbursement model, and the 2026 coding revisions are already affecting reimbursement.
What ROCR would change if Congress passes it
The Radiation Oncology Case Rate (ROCR) Value Based Program Act was reintroduced in March 2025 as S.1031 in the Senate and H.R.2120 in the House of Representatives. The legislation has bipartisan sponsorship and support from more than 80 healthcare organizations. However, it remains proposed legislation and has not been enacted.
The concept behind ROCR is straightforward. Rather than paying separately for every treatment fraction, Medicare would reimburse providers with a single case rate covering an entire episode of care for designated cancer types. Under today’s fee-for-service structure, practices treating prostate cancer in five fractions instead of twenty typically receive lower reimbursement despite providing evidence-based care. ROCR is designed to eliminate that financial disincentive.
From a planning standpoint, timing is more important than the payment methodology itself. According to the current bill, CMS would have one year after enactment to develop regulations, followed by another year before the program becomes effective. Even if Congress passed the legislation soon, practices would likely continue billing under the current reimbursement system well into 2027.
Bill status at the time of publication: Pending. While industry organizations continue advocating for its inclusion in broader Medicare payment legislation, no law has been passed yet.
What actually changed on January 1, 2026
This is where many practices are seeing an immediate financial impact, even though it received far less attention than the proposed ROCR legislation.
Treatment delivery coding was streamlined into three complexity-based CPT codes: 77402, 77407, and 77412. These codes now apply to services provided in both hospital outpatient departments and freestanding treatment centers. The previous delivery codes 77385 and 77386 have been removed, and the Medicare Physician Fee Schedule delivery G-codes are no longer valid.
Image guidance also changed significantly. All image guidance services have been consolidated under 77387, which is now billed as the professional component only. The technical component has been incorporated into the updated treatment delivery codes. Practices that continue submitting separate technical component charges for image guidance are experiencing avoidable claim denials.
In addition to these coding revisions, CMS finalized a 2.5% efficiency adjustment affecting work RVUs and the intraservice physician time for non-time-based services. Combined with updates to practice expense calculations, CMS estimates an overall specialty impact of approximately -1%. However, actual reimbursement changes vary depending on service mix, treatment setting, equipment expenses, and supply costs. Some procedures may receive lower reimbursement in hospital outpatient facilities while others perform better in freestanding centers.
Practices should also verify their Medicare fee schedules. Early CY 2026 payment files contained proposed reimbursement values instead of the finalized efficiency-adjusted amounts. Organizations that imported those preliminary files may now have inaccurate expected reimbursement figures, making it difficult to identify genuine underpayments.
Where episode payment is real today
Episode-based reimbursement does exist today, but not through Medicare radiation oncology.
The first area is commercial insurance contracts. Several private payers already reimburse radiation therapy through bundled or case-rate agreements negotiated directly with practices. Each payer establishes its own episode definitions, qualification criteria, trigger events, exclusions, and reimbursement methodology. These arrangements differ considerably from one insurer to another. If your payer agreements have not been reviewed recently, your organization could already be operating under episode-based payment terms without the billing team fully understanding the contract requirements.
The second example is TEAM (Transforming Episode Accountability Model). CMS officially launched TEAM on January 1, 2026, with the model continuing through December 31, 2030. Participation is mandatory for selected acute care hospitals located in designated geographic regions. TEAM includes five surgical episode categories:
- Lower extremity joint replacement
- Surgical hip femur fracture treatment
- Spinal fusion
- Coronary artery bypass graft
- Major bowel procedures
Radiation oncology is not included in TEAM, and oncology-related inpatient admissions are excluded from episode spending calculations.
Even so, TEAM provides an important indication of CMS’s direction. The agency has demonstrated a willingness to make episode-based payment models mandatory rather than voluntary. If a radiation oncology case-rate program is eventually implemented, practices should be prepared for the possibility that participation may also be required.
The billing errors costing the most in the 2026 code set
Our claim reviews throughout 2026 consistently reveal four recurring billing issues that are leading to unnecessary payment delays and revenue loss.
Billing deleted codes.
Practices that have not updated their systems continue submitting claims using 77385, 77386, and the retired delivery G-codes. In most cases, these claims are rejected before adjudication rather than denied, leaving them stuck in clearinghouse work queues instead of appearing on standard aging reports.
Incorrect billing of 77387.
Submitting the technical component separately for 77387, which is now bundled into the delivery codes, results in predictable claim denials. Appealing these claims only consumes staff resources because the reimbursement was never payable under the updated rules.
Assigning complexity based on old coding habits.
The three new treatment delivery codes are determined by documented treatment complexity—not by the retired CPT code previously used. Simply crosswalking from the old code instead of reviewing clinical documentation can lead to incorrect coding in either direction.
Outdated contracted reimbursement rates.
Commercial insurers update the new CPT codes according to their own implementation schedules. Until those revised rates are loaded into your practice management system, expected reimbursement calculations remain inaccurate, making legitimate underpayments difficult to identify.
How to get episode-ready before the rules arrive
Practices cannot prepare for an episode-based payment system by billing for a model that has not yet been implemented. What they can do is establish the financial reporting that future case-rate reimbursement will require: understanding the total cost and total revenue associated with each completed course of treatment by cancer site.
Very few organizations currently measure performance this way. Most continue tracking revenue per claim or per treatment fraction, which provides limited insight into the profitability of an entire course of care. Under an episode-based payment model, profitability will depend on the complete treatment episode rather than individual services.
Begin by evaluating your five highest-volume disease sites. For each one, calculate:
- Total charges
- Total collections
- Total treatment fractions delivered
- Staff time
- Equipment utilization from simulation through the final treatment session
Review a full year of completed patient courses. Many practices discover that financial performance varies much more between disease sites than expected.
Next, model those same treatment courses using a hypothetical flat case-rate payment. If certain disease sites become financially unsustainable under bundled reimbursement, you’ll know exactly where clinical workflows or scheduling processes may need improvement—and you’ll have time to make those changes before a new payment model becomes reality.
