Medicare Payment Regulations and Rate Setting

Why the Medicare Payment Rate Matters

With health care costs on the rise and America's population aging, policymakers have pursued efforts to maintain solvency for the Medicare Trust Fund without increasing payroll taxes. For providers, these policies have resulted in an increasingly unstable payment system and declining payment rates relative to inflation.

Compounding this issue are large, annually proposed cuts to Medicare payment rates. Medicare Part B covers medical nutrition therapy (MNT) services provided by qualified registered dietitians or nutrition professionals for certain beneficiaries.

The Academy's Stance on Medicare Payment Rate

The Academy advocates for preventing cuts and improving Medicare Part B payment rates for registered dietitian nutritionists (RDNs). This includes direct advocacy with policymakers, participation in coalitions, and efforts to elevate the voices and experiences of RDNs in the policy process.

Medicare payment is also shaped by medical coding, which is overseen by the American Medical Association (AMA) and designed to reflect how services are delivered in clinical practice. Because these coding decisions directly influence how services are valued and reimbursed, the Academy actively engages in this process as part of its broader advocacy to ensure appropriate recognition and payment for RDN services.

Regulatory Priorities

The Academy of Nutrition and Dietetics supports federal regulatory policies that strengthen Medicare reimbursement and expand beneficiary access to MNT provided by registered dietitian nutritionists (RDNs). The Academy advocates for preventing annual Medicare Part B payment cuts, establishing stable and sustainable payment updates that better reflect inflation and the cost of care, and ensuring appropriate recognition and valuation of RDN services within the Medicare Physician Fee Schedule.

In addition, the Academy supports regulatory actions that expand access to MNT, including broader coverage for chronic diseases, continued access to telehealth-delivered nutrition services, and policies that allow Medicare beneficiaries to receive timely, evidence-based nutrition care that improves health outcomes and reduces overall health care costs.

Key Medicare Regulations

The Centers for Medicare & Medicaid Services issues several major regulations each year that influence how nutrition services are delivered, documented and reimbursed across health care settings. The Academy monitors these rules, submits comments to CMS and advocates for policies that support patient access to nutrition care and appropriate recognition of registered dietitian nutritionists.

As the expectations of federal policymakers for the health care system evolve, RDNs are increasingly positioned as essential contributors to both clinical outcomes and financial performance across healthcare settings. Of particular importance are the Inpatient Prospective Payment System (IPPS), Skilled Nursing Facility Prospective Payment System (SNF PPS), End-Stage Renal Disease (ESRD) Payment System, Medicare Advantage rate announcements, and the Physician Fee Schedule (MPFS), and Medicare Hospital Outpatient Prospective Payment, which collectively redefine how nutrition services are delivered, documented, and reimbursed.

A central theme of recent updates to these regulations is the elevation of nutrition as a critical driver of patient outcomes, cost containment, and compliance. While historically considered a supportive service, nutrition care is now being directly integrated into quality metrics, bundled payment models, and risk-adjusted reimbursement frameworks.

From mandatory malnutrition quality reporting in hospital settings to increased audit scrutiny in post-acute care and direct ties between nutrition interventions and federal payment penalties, dietitians are operating in a more data-driven, accountable, and strategically significant environment than ever before. Ultimately, these regulatory developments signal a fundamental shift: nutrition care is no longer ancillary—it is a core component of high-quality, value-based healthcare delivery.

Get Involved

Understanding how Medicare payment rates are determined and what laws and regulations underlie these rates is crucial to being an informed advocate for the profession. The MNT and Payment Affinity Group meets quarterly to discuss Academy advocacy priorities and strategies related to enhancing access to MNT and nutrition care services.
