Medicare-Covered Weight Loss Options in 2025: What You Need to Know

Losing weight is challenging—but for older adults or individuals with chronic conditions, it can also be critical to long-term health. If you're on Medicare and wondering what weight loss treatments or programs are covered, you’re not alone. The good news: Medicare has expanded its support for weight management, especially when tied to chronic disease prevention or treatment.

Here’s what Medicare covers—and what it doesn’t—when it comes to medically supported weight loss in 2025.

Does Medicare Cover Weight Loss Programs?

Yes, but with limitations. Original Medicare (Parts A and B) does not cover commercial weight loss programs like Weight Watchers, Jenny Craig, or Noom—but it does cover medically necessary weight loss treatments and services, especially when linked to conditions like diabetes, obesity, or heart disease.

Medicare-Covered Weight Loss Options (2025)

1. Behavioral Therapy for Obesity

  • What it is: In-person or telehealth counseling with a healthcare provider
  • Who qualifies: BMI of 30 or higher
  • Coverage: 100% (no coinsurance or deductible under Part B if provider accepts assignment)
  • Frequency: Up to 22 sessions per year

Medicare covers intensive behavioral therapy (IBT) that focuses on nutrition, activity, and behavioral changes.

2. Medical Nutrition Therapy (MNT)

  • What it is: Personalized diet and nutrition counseling from a registered dietitian
  • Who qualifies: Must have diabetes or kidney disease, or have had a kidney transplant in the last 36 months
  • Coverage: 100% under Part B
  • Includes: Initial assessment + follow-ups

Some Medicare Advantage (Part C) plans extend this coverage even without diabetes if obesity is present.

3. Diabetes Prevention Program (MDPP)

  • What it is: A CDC-approved lifestyle change program focused on losing weight to reduce the risk of type 2 diabetes
  • Who qualifies: Overweight (BMI >25), pre-diabetic, and no prior diagnosis of diabetes
  • Coverage: 100% for qualified individuals once per lifetime

MDPP offers in-person and virtual classes focused on nutrition, exercise, and weight control over a 12-month period.

4. Prescription Weight Loss Medications

  • Are they covered? Sometimes.
  • Part D Coverage: Varies by plan; most do not cover weight loss drugs unless prescribed for another condition like diabetes (e.g., Ozempic, Wegovy)
  • Medicare Advantage Plans: May include prior authorization pathways for GLP-1s and anti-obesity meds in 2025

If you're considering medications like Saxenda, Wegovy, or Zepbound, check your Part D or Advantage plan formulary carefully.

5. Bariatric Surgery

  • What it is: Surgical weight loss procedures (e.g., gastric bypass, sleeve gastrectomy)
  • Who qualifies: BMI of 35+ with at least one comorbidity (diabetes, hypertension, sleep apnea)
  • Coverage: Part A (hospital) and Part B (surgeon/anesthesia)
  • Requirement: Must be performed at a Medicare-approved facility

Medicare covers bariatric surgery only when it’s deemed medically necessary, not cosmetic.

What’s Not Covered by Medicare?

Medicare does not cover:

  • Gym memberships (except some Advantage plans with SilverSneakers)
  • Commercial weight loss programs (WW, Noom, etc.)
  • Weight loss supplements
  • Meal delivery programs (unless part of post-discharge home health care)

However, many Medicare Advantage (Part C) plans offer added weight loss benefits—from fitness apps to meal support and nurse coaching.

How to Maximize Medicare for Weight Loss

  • Check for obesity-related diagnosis codes in your medical records (BMI >30).
  • Ask your provider to refer you to a dietitian or IBT program.
  • Review your Medicare Advantage plan’s extras—some include wellness credits.
  • Combine covered services like IBT + MNT for a more holistic approach.
  • Request a “medically necessary” letter if your provider wants to explore newer treatments or medications.

Final Thoughts: A New Era of Weight Loss Coverage for Seniors

Medicare is evolving—and while it still doesn’t cover trendy diet apps or prepackaged meal plans, it does now support evidence-based, medically supervised weight loss for people who need it most. Whether you're managing diabetes, recovering from heart disease, or simply trying to stay mobile and independent, these covered services can make a major difference.

Talk to your provider and leverage the full power of your Medicare benefits—especially if weight loss could improve your health and quality of life.
