Medical Nutrition Therapy Act of 2026

The Medical Nutrition Therapy Act of 2026 (S.3934) was introduced in the Senate on February 26, 2026, and subsequently referred to the Committee on Finance. This bill aims to amend title XVIII of the Social Security Act to expand Medicare coverage for medical nutrition therapy services. Currently, Medicare covers these services only for individuals with diabetes or kidney disease, provided by a registered dietitian or nutrition professional with a physician referral. S.3934 proposes extending coverage to individuals with conditions such as obesity, eating disorders, cancer, and HIV/AIDS, and would allow physician assistants, nurse practitioners, clinical nurse specialists, and clinical psychologists (for eating disorders) to make referrals. This is an early-stage bill, with only two cosponsors, indicating it has just begun its legislative journey. This bill does not explicitly authorize or appropriate a specific funding amount. Instead, it expands the scope of services covered under the existing Medicare Part B program. The financial mechanism is an increase in the volume of reimbursable services under Medicare. This means that if the bill passes, the federal government would pay for more medical nutrition therapy services through the existing Medicare payment structures, rather than allocating new, dedicated funds. The impact would be an increase in the total expenditure on these services within the Medicare budget, funded by general revenues. Structural winners would be healthcare providers specializing in nutrition services, including registered dietitians and nutrition professionals, as well as the broader healthcare system that manages chronic conditions. Companies like UnitedHealth Group ($UNH), Centene Corporation ($CNC), and Humana Inc. ($HUM), which operate significant Medicare Advantage and Part B administrative services, would see an increase in claims processing and potentially improved health outcomes for their members, which can positively impact their business models. AMN Healthcare Services ($AMN) would likely see increased demand for staffing nutrition professionals. CVS Health ($CVS) could also benefit through its Aetna insurance arm and its retail health clinics. There are no clear structural losers identified by this bill, as it expands coverage rather than restricting it. Looking at recent market data, several potentially affected tickers have shown positive trends. UnitedHealth Group ($UNH) is up +4.11% in the last 7 days and +42.09% in the last 30 days, currently at $368.04. Centene Corporation ($CNC) has seen a significant increase of +25.07% in the last 7 days and +52.16% in the last 30 days, trading at $48.69. Humana Inc. ($HUM) is up +6.77% in the last 7 days and +37.27% in the last 30 days, at $232.11. CVS Health ($CVS) is up +6.21% in the last 7 days and +15.84% in the last 30 days, at $81.18. AMN Healthcare Services ($AMN) is up +1.82% in the last 7 days and +12.59% in the last 30 days, at $21.29. These positive movements across major healthcare players suggest a generally bullish sentiment in the sector, though these specific movements cannot be directly attributed solely to this early-stage bill. The bill's progression would likely contribute to this positive outlook for companies involved in Medicare services. For this bill to become law, it must pass the Senate Committee on Finance, then the full Senate, then the House of Representatives, and finally be signed by the President. Given its early stage and the current date of April 28, 2026, significant legislative steps remain. The existence of a related bill, HR6199 (Medical Nutrition Therapy Act of 2025), suggests bipartisan interest in the issue, which could aid its progression. However, the related bill is from the previous Congress session and has not advanced, indicating that similar legislation has faced challenges in the past. There are no direct presidential actions that amplify or conflict with this bill. The Presidential Memorandum on Accelerating Medical Treatments for Serious Mental Illness is related to mental health but does not directly address nutrition therapy coverage under Medicare.
