Medicare does not pay radiation oncology on an episode basis in 2026. The RO Model was shelved and never launched. The ROCR Act is still a bill. What did land on January 1 is a rebuilt code set and a 2.5% efficiency cut, and most of the revenue damage this year is coming from practices billing the old way against new codes. Get the charge master right first. Build episode-level cost data second.

Most radiation oncology practices we talk to think a Medicare bundle is already running. It isn’t. The gap between what the specialty expects and what the rules say is where the money is leaking in 2026, because staff are preparing for a model that doesn’t exist while billing a code set that changed underneath them on January 1.

Here’s what’s real, what’s pending, and what to do about both.

Radiation oncology is still paid fee-for-service under Medicare in 2026. No episode-based model applies to the specialty. The Radiation Oncology Model was never implemented, and the ROCR Value Based Program Act (S.1031 / H.R.2120) remains pending legislation. The real 2026 change is the consolidation of treatment delivery codes into 77402, 77407 and 77412, plus a 2.5% efficiency adjustment to work RVUs.

The Medicare episode model for radiation oncology doesn’t exist

CMS spent years designing the Radiation Oncology Model. It never started. The model carried payment reductions the specialty said would threaten access, and reporting requirements practices called unworkable. After repeated delays it was shelved, and it has stayed shelved.

So the specialty sits in an odd spot. Everyone in radiation oncology has been told for six years that a bundle is coming. The billing department is still submitting per-fraction claims under fee-for-service, exactly as it did in 2019.

That mismatch has a cost. Practices defer charge master work because they assume the whole system is about to be replaced. Then the code set changes anyway, and the deferred work becomes an emergency.

If your practice has been waiting to fix billing workflows until the bundle arrives, stop waiting. Fee-for-service is the operating reality for at least the next two years, and the 2026 code changes are already costing money.

What ROCR would change if Congress passes it

The Radiation Oncology Case Rate Value Based Program Act was reintroduced in March 2025 as S.1031 in the Senate and H.R.2120 in the House. It’s bipartisan and it has support from more than 80 organizations. It’s also still a bill.

The core idea is simple. Medicare would pay a case rate for each patient’s episode of care for named cancer types, instead of paying for each fraction delivered. Today a practice that finishes a prostate course in five sessions instead of twenty earns less for better care. ROCR breaks that link.

The timeline matters more than the design for planning purposes. Under the bill text, CMS gets a year after enactment to write regulations, and the program takes effect a year after enactment. Even in the best case, a practice would be billing the current way well into 2027.

Bill status as of publication: pending. Advocacy groups have pushed for inclusion in a broader Medicare payment package. Nothing has been enacted.

What actually changed on January 1, 2026

This is the part costing practices real dollars right now, and it got far less attention than ROCR.

Treatment delivery collapsed into three complexity levels: 77402, 77407 and 77412. The same three codes apply whether the service happens in a hospital outpatient department or a freestanding center. Codes 77385 and 77386 are gone. The delivery G-codes previously reported under the fee schedule are also gone.

Image guidance consolidated into a single code, 77387. It’s now professional component only. The technical component is bundled into the updated delivery codes. Practices still billing image guidance technical separately are generating denials on every claim.

On top of the coding change, CMS finalized a 2.5% efficiency adjustment to work RVUs and the intraservice time portion for non-time-based services. Combined with the practice expense overhaul, CMS put the specialty-level impact at about -1%. That average hides enormous variation. Some services pay less in a hospital setting and more in a freestanding office, and the direction depends on how supply and equipment costs land for your specific mix.

Check your fee files. Early CY 2026 payment files released by Medicare carried proposed values, not finalized efficiency-adjusted amounts. Practices that loaded those files are posting wrong expected reimbursement on every claim and can’t tell an underpayment from a normal one.

Where episode payment is real today

Two places. Neither is a Medicare radiation oncology bundle.

The first is commercial contracts. Some payers already run case rate or bundled arrangements for radiation therapy, negotiated practice by practice. These carry their own episode definitions, trigger events and exclusions, and they don’t match each other. If your contract file hasn’t been read line by line in two years, you may already be under episode payment without your billing team knowing the rules.

The second is TEAM, the Transforming Episode Accountability Model, which CMS launched on January 1, 2026 and runs through 2030. It’s mandatory for selected acute care hospitals in chosen geographic areas. It covers five surgical procedures: lower extremity joint replacement, surgical hip femur fracture treatment, spinal fusion, coronary artery bypass graft and major bowel procedures. Radiation oncology isn’t one of them, and oncology inpatient admissions are excluded from episode spending.

TEAM still matters as a signal. CMS is willing to make episode models mandatory rather than voluntary. If a radiation oncology case rate arrives, assume participation won’t be optional.

The billing errors costing the most in the 2026 code set

Four patterns show up repeatedly in claims we review this year.

Billing deleted codes. Systems that weren’t remapped keep firing 77385 and 77386 and the retired G-codes. These reject rather than deny in most cases, which means they sit unworked in a clearinghouse queue instead of showing up on an aging report.

Splitting 77387 wrong. Billing a technical component that’s now bundled produces a denial, and appealing it wastes staff time on a claim that was never payable.

Mapping complexity by habit. The three delivery levels are defined by complexity, not by the old code a service used to carry. Crosswalking from the retired code instead of coding from documentation puts services in the wrong level, in both directions.

Stale contracted rates. Commercial payers load the new codes on their own schedules. Until they do, your expected reimbursement is wrong and underpayments look normal.

How to get episode-ready before the rules arrive

You can’t bill a case rate that doesn’t exist. You can build the one thing a case rate makes non-negotiable: cost and revenue per completed course of treatment, by cancer site.

Almost no practice tracks this. Most report per-fraction volume and per-claim revenue, which tells you nothing about whether a full prostate course or a full breast course makes money. Under a case rate, that number is the entire business model.

Start with your five highest-volume disease sites. For each, pull total charges, total collections, total fractions delivered and staff and machine time from simulation through the final fraction. Do this for a full year of completed courses. The spread between your best and worst site is usually wider than anyone expects.

Then run the same courses against a hypothetical flat payment. If a case rate would sink you, you now know which sites need protocol or scheduling changes, and you have two years to make them rather than two quarters.

How Qualigenix supports radiation oncology practices

Our team handles the unglamorous part of this: charge master remapping, code-level audits against documentation, denial rework on the new delivery and image guidance codes, and payer contract review to find episode language already sitting in your agreements.

Across the practices we serve, we run a 99% claim accuracy rate, a 95% first-pass acceptance rate and a 36-day average collection cycle, with a 30% reduction in AR days. Onboarding takes as few as six days, which matters when a code set changed six months ago and claims are still rejecting.

Frequently asked questions

Is radiation oncology paid on an episode basis under Medicare in 2026?

No. Medicare pays radiation oncology fee-for-service in 2026. The RO Model was never implemented and ROCR is still a pending bill.

What happened to the CMS Radiation Oncology Model?

It was delayed indefinitely and shelved. Stakeholders objected to the size of its payment reductions and the reporting burden. ROCR was built to replace it while keeping the episode payment concept.

Which radiation therapy CPT codes changed on January 1, 2026?

Delivery consolidated into 77402, 77407 and 77412 across both settings. Codes 77385 and 77386 were deleted along with the delivery G-codes. Image guidance consolidated into 77387, professional component only.

What is the 2026 efficiency adjustment?

A 2.5% reduction CMS finalized to work RVUs and intraservice physician time for non-time-based services. Radiation oncology services fall in scope. CMS put the specialty-level impact at about -1%, but individual clinics vary widely.

Would ROCR reward hypofractionation?

It would remove the current penalty. Paying per patient rather than per fraction means a shorter evidence-based course no longer reduces revenue. Practices already using shorter protocols would benefit most.

Does TEAM apply to radiation oncology?

No. TEAM covers five surgical procedures at selected hospitals from 2026 through 2030. Radiation oncology isn’t included, and oncology inpatient admissions are excluded from episode spending.

How soon would a case rate take effect if ROCR passed?

Under the bill text, CMS must issue regulations within a year of enactment and the program takes effect a year after enactment. Practices would keep billing the current way through that window.
