Updated January 20, 2026 at 1:03 PM UTC

The Medical Nutrition Therapy Act of 2023 amends the Social Security Act to broaden Medicare coverage of medical nutrition therapy (MNT). It expands eligibility beyond diabetes and renal disease to a wide range of chronic conditions and lets more health professionals provide the services. The changes affect Medicare Part B beneficiaries who have any of the listed conditions and the providers who deliver MNT.

Key Provisions

  • Adds many chronic diseases and conditions—including diabetes, prediabetes, obesity, hypertension, dyslipidemia, malnutrition, eating disorders, cancer, gastrointestinal diseases, HIV/AIDS, cardiovascular disease, and others the Secretary deems medically necessary—to the list of conditions for which Medicare will cover MNT.
  • Allows physicians, physician assistants, nurse practitioners, clinical nurse specialists, and, for eating‑disorder cases, clinical psychologists to furnish MNT services under Medicare.
  • Specifies that MNT services for individuals on maintenance dialysis are excluded from the expanded coverage.
  • Updates the Medicare exclusion language to reflect the new list of covered conditions and provider types.
  • Sets the new rules to take effect for services provided beginning two years after the law is enacted.

S. 3297

IN THE SENATE OF THE UNITED STATES

November 14 (legislative day, November 13), 2023

Ms. Collins (for herself and Mr. Peters) introduced the following bill; which was read twice and referred to the Committee on Finance

A BILL

To amend title XVIII of the Social Security Act to expand the availability of medical nutrition therapy services under the Medicare program.

1.

Short title

This Act may be cited as the Medical Nutrition Therapy Act of 2023.

2.

Findings

Congress finds the following:

(1)

Over two-thirds of Medicare fee-for-service beneficiaries have 2 or more chronic conditions, many of which can be prevented, delayed, treated, or managed through nutrition.

(2)

Individuals from many racial and ethnic minority backgrounds are more likely to be diagnosed with chronic diseases such as diabetes, prediabetes, chronic kidney disease, end-stage renal disease, and obesity.

(3)

Coverage for medical nutrition therapy is only available to Medicare Part B beneficiaries with diabetes or a renal disease, despite medical nutrition therapy being part of the standard of care, in clinical guidelines, and medically necessary for many more chronic conditions.

(4)

Medical nutrition therapy has been shown to be a cost-effective component of treatment for obesity, diabetes, hypertension, dyslipidemia, HIV infection, unintended weight loss in older adults, and other chronic conditions.
