Reston, VA – A new Harvey L. Neiman Health Policy Institute study found that physician reimbursement per Medicare patient decreased 2.3% between 2005 and 2021 when accounting for inflation, despite a concurrent increase of 45.5% in physician services to each patient. These reimbursement trends varied widely by physician specialty (-57.6% for cardiac surgery to +189.1% for pain management). In comparison, non-physician practitioners’ reimbursement per Medicare patient increased more than 3-fold over the same period. The research, published today in INQUIRY: The Journal of Health Care Organization, Provision, and Financing evaluated changes in payments for Part B services for 100% of traditional Medicare beneficiaries between 2005 and 2021.

The study was designed to evaluate how provider reimbursement has been affected by the Medicare statutory budget neutrality requirement. Importantly, the research investigated the dynamics of the underlying factors that affect reimbursement—volume, reimbursement per service, and inflation. Medicare reimburses clinicians based on the resource intensity of a service, measured as relative value units (RVUs). The RVUs assigned to a service are multiplied by a dollar amount per RVU (the conversion factor) to determine the Medicare payment.

“The statutory requirement for budget neutrality requires that RVUs and/or the conversion factor adjust so that Medicare expenditures do not exceed the budget as new services are introduced or as volumes of existing services increase. In other words, budget neutrality is a zero-sum game. Expansions in one area necessitate contractions elsewhere” stated Eric Christensen, PhD, Research Director at the Neiman Institute. “Our study shows that physicians are now paid 2.3% less per beneficiary compared with 16-years ago as budget neutrality necessitated an offset given the substantial shift to other provider types, most notably non-physician practitioners.”

Although the research found that across all medical providers and suppliers, payments per beneficiary increased 9.9%, payments to non-physician practitioners (e.g., nurse practitioners) increased 206.5% while payments to limited-license physicians (e.g., podiatrists) increased 16.3% and payment to medical suppliers increased 44.4%. While some physician specialties experienced reimbursement growth, sixteen physician specialties experienced reimbursement declines. Of these, thirteen experienced reimbursement declines despite higher volumes per beneficiary. These included psychiatrists, cardiologists, urologists, OB/GYN, internal medicine, internists, pulmonologists, radiologists, gastroenterologists, anesthesiologists, among others.
