Over the past 20 years, Medicare coverage for oncology services in the United States has shifted dramatically. While the costs of radiation oncology have only increased due to factors such as inflation, higher costs for high-tech equipment, and rising operational costs, Medicare reimbursements have not kept pace with these cost developments. This has inevitably put a huge strain on clinics, providers, and patients who rely on coverage plans to cover their medical needs but are unable to do so.
Medicare’s inability to accommodate for the increase in oncology, specifically radiation oncology, services has been illustrated by the 2025 ASCO Quality Care Symposium. Using publicly available Medicare Physician Fee Schedule (MPFS) data from 2005 to 2025, it was shown that the Consumer Price Index, a general measure of inflation trends, has increased 66.6% over 2 decades, with medical-specific inflation estimated to have risen by roughly 77.4%. As dramatically as these costs have risen, the MPFS has increased a mere 4.5% for oncology-related services, which, when accounting for inflation, illustrates a reduction in oncology-related pay-out services of 25.4%.1
What all these percentages illustrate is that there is a widening gap between the costs of oncologic practices and the reimbursement rates. This inevitably poses a threat to clinics, patients, and the ability to offer and access necessary cancer care.
In another study specifically exploring radiation oncology Medicare and Medicaid reimbursement trends, it was shown that from 2010 to 2019 there was a $433 million (19%) budget cut. When accounting for inflation, the pay cut is estimated at approximately $686 million (a 27% decrease). Simply put, government funding for radiation oncology is falling behind as the actual cost of providing these complex treatments continues to climb.2
Because federal law does not permit doctors to bill Medicare patients directly for the funding gaps, clinics end up absorbing the losses. What this means, and ultimately translates to, is a necessary method to offset the medical losses. What ends up happening is clinics will negotiate higher payment rates with private insurance companies, push monthly premiums and deductibles up, and often force clinics to close—especially in lower-income areas.
Regardless of the Medicare coverage, radiation oncology remains a necessary specialty that demands significant investments in high-tech equipment like linear accelerators, technical workforce, physicists, and dosimeters. As public funding continues to shrink, the real challenge for the future of radiation oncology will be finding ways to adapt without compromising the quality of care patients deserve.
