CMS Proposes Changes to Medicare Fee Schedule for ID Physicians
The IDSA Member Portal is scheduled for system maintenance on Saturday, July 18, from 8 p.m. to 11:59 p.m. ET. During this period, access to the portal, membership transactions, and program management will be temporarily unavailable. However, all other IDSA services will continue to operate as usual.
On July 14, 2026, the Centers for Medicare & Medicaid Services (CMS) proposed changes to the Medicare Physician Fee Schedule for the 2027 calendar year. These updates, effective January 2027, could significantly impact payment and policy for Medicare Part B services. The proposed rule is particularly relevant for infectious disease (ID) physicians, highlighting potential changes in payment structures, practice expense policy, and Medicare quality reporting requirements.
The CMS proposal introduces differentiated conversion factors for clinicians involved in Alternative Payment Models and those who are not. It also continues reforms to the practice expense (PE) methodology. Notably for ID physicians, CMS plans to modernize the PE policy by phasing out the outdated indirect PE index. This shift will focus on more current code-level inputs while supporting direct supervision through real-time audio and video technology.
Specifically, CMS suggests a two-year transition away from PE methodology aspects reliant on the indirect PE index. This aims to better align with current specialty-level survey data and allocations. CMS invites comments on the 50% indirect PE allocation finalized for 2026, assessing its relevance for facility-based physicians, especially those employed by hospitals where overheads are otherwise considered.
ID physicians are not expected to face an overall specialty impact from relative value unit modifications, but proposed reductions in the conversion factor for CY 2027 are critical. These changes lower the factor to approximately $33.17 for qualifying APM physicians and $33.03 for non-qualifying physicians. This reflects estimated decreases of 1.19% and 1.68%, respectively, without factoring in these specific conversion factor changes.
These revisions are pivotal as services provided by ID physicians often involve complex outpatient care, necessitating accurate recognition of clinical support and care coordination expenses. In response, the IDSA will analyze the rule meticulously, submitting detailed feedback to CMS and possibly pursuing legislative actions to guard against detrimental policies. The organization remains dedicated to advancing reimbursement reforms to benefit ID practitioners and their patients.
