Senators Reintroduce Bill to Expand Reimbursement for Radiologist Assistants

Why It Matters

Expanding Medicare reimbursement for RAs could alleviate imaging bottlenecks, especially in rural areas, while reshaping the radiology workforce and payment landscape.

Key Takeaways

• MARCA reintroduced to allow Medicare payment for RA services in hospitals
• ACR shifts from neutral to supporting MARCA, backing reimbursement expansion
• Radiologist opposition cites potential workforce drain and scope‑of‑practice concerns
• Bill aims to ease imaging access in rural Medicare markets
• Multiple radiology societies endorse MARCA as top 2026 legislative priority

Pulse Analysis

The Medicare Access to Radiology Care Act (MARCA) returns to Capitol Hill after multiple prior attempts, reflecting growing pressure to address a longstanding Medicare reimbursement disparity. Currently, radiologist assistants can bill for services rendered in physician offices but not in hospitals, where they are most often employed. By authorizing claims for nondiagnostic procedures performed under direct physician supervision, MARCA seeks to unlock revenue streams for hospitals, encouraging broader RA utilization and helping mitigate the chronic radiology staffing shortfall that has strained imaging throughput nationwide.

Political momentum for MARCA has shifted notably with the American College of Radiology (ACR) moving from a neutral stance to active endorsement. The ACR’s support signals alignment among many radiology professionals who view RAs as a distinct, well‑trained extender capable of expanding capacity without compromising physician‑led interpretation. Nonetheless, a vocal segment of radiologists remains skeptical, fearing that the bill could lure technologists into RA roles, erode the specialist pipeline, and set a precedent for further delegation of clinical duties to non‑physicians. These concerns underscore the delicate balance between workforce optimization and preserving the expertise that underpins high‑quality imaging.

If enacted, MARCA could have immediate benefits for Medicare beneficiaries, particularly in rural and underserved communities where imaging delays are common. By removing the reimbursement barrier, hospitals may deploy RAs more extensively, shortening appointment wait times and supporting timely diagnoses for conditions ranging from cancer to cardiovascular disease. Moreover, the policy could influence future Medicare rulemaking, prompting a broader reevaluation of how ancillary providers are compensated across specialties. Stakeholders will watch closely to gauge whether the anticipated efficiency gains materialize without unintended shifts in the radiology labor market.
