Medicare Covers Obesity Now. Almost Nobody Knows.

On July 1, 2026, Medicare began paying for obesity medication for the first time in its history. Behavioral counseling has been covered since 2011 and goes almost unused. Medicaid is a fifty-state patchwork that shrank in January. Here is what each program actually covers, who qualifies, and what is proposed for 2027.

Built from the 2026 National Obesity Policy Forum, Washington, DC, July 30, 2026, and cross-checked against CMS, CDC, KFF, and Federal Register primary sources. Coverage status current as of September 2026; live state Medicaid status is on the Insurance Coverage page.

By the numbers

$50

a month. The flat copay for Wegovy, Zepbound, or Foundayo under the Medicare GLP-1 Bridge, July 1, 2026 through December 31, 2027, for beneficiaries who meet the clinical criteria.

Core Concepts

Six things to know before you ask your doctor.

Two are law. Two are benefits that already exist. One is next year. One is the fifty-state problem. Click any card for the pearls and the sources.

The Law That Said No

Since 2006 the Part D statute has barred Medicare from paying for weight-loss drugs. It still does. Everything covered today is a workaround.

The Medicare GLP-1 Bridge

$50 a month, three drugs, a BMI-plus-comorbidity grid, and an expiration date. The fine print that decides who qualifies.

Counseling Has Been Covered Since 2011

Up to 22 visits a year at no cost. Fifteen years in, almost nobody has used it. The delivery rules explain why.

At a Glance

Who covers what, and where.

The treatment ladder against the two programs. For which states cover obesity medication right now, see the live Medicaid tracker below.

Service	Medicare	Medicaid
ScreeningBMI and counseling referral	Covered BMI recorded at the Annual Wellness Visit. Obesity screening is a USPSTF grade B service, so no cost sharing.	Varies Required for Medicaid expansion adults (USPSTF A and B services) and for children under 21 through EPSDT. Optional in traditional adult Medicaid.
Behavioral therapyIntensive lifestyle counseling	Covered since 2011 Intensive Behavioral Therapy for obesity, BMI 30 or higher, up to 22 visits over 12 months, no copay. Must be furnished in a primary care setting. Individual (G0447) and group (G0473) codes.	Varies Expansion adults get it as a USPSTF B service. Children under 21 get medically necessary counseling through EPSDT. Traditional adult coverage is a state choice.
Dietitian servicesMedical nutrition therapy	Covered for diabetes and CKD Registered dietitians bill Part B for diabetes, non-dialysis kidney disease, and 36 months after kidney transplant. Obesity alone does not qualify. Dietitians can deliver IBT in primary care under supervision.	Varies State option for adults. Most states cover nutrition counseling for children through EPSDT. Check the state plan.
Diabetes preventionPrediabetes lifestyle program	Covered since 2018 Medicare Diabetes Prevention Program: prediabetes by lab plus BMI 25 or higher (23 if Asian). Year-long CDC-recognized curriculum, no cost sharing, once per lifetime.	State option Some states cover the National Diabetes Prevention Program for Medicaid adults; many do not.
Obesity medicationGLP-1 and other anti-obesity drugs	Covered, temporarily Medicare GLP-1 Bridge, July 1, 2026 through December 31, 2027: $50 a month for Wegovy, Zepbound KwikPen, or Foundayo if you meet the BMI grid. Separately, Part D covers these drugs for type 2 diabetes, cardiovascular risk, sleep apnea, and MASH. The statutory exclusion for weight loss itself remains.	Varies by state Every state must cover GLP-1s for type 2 diabetes. Coverage for obesity itself is a state choice and changes with state budgets. See the live state tracker.
Bariatric surgeryGastric bypass, sleeve, and others	Covered National Coverage Determination 100.1: BMI 35 or higher, at least one obesity-related comorbidity, and prior unsuccessful medical treatment. Bypass, sleeve, duodenal switch, and adjustable band.	Most states Some form of coverage in 48 states as of the 2022 Obesity Across America report. Criteria, waiting periods, and procedure lists vary widely.
Health coachingIndividual and group	Proposed for 2027 The CY 2027 fee schedule proposal would pay nationally for health and well-being coaching codes 0591T, 0592T, and group 0593T, delivered by trained coaches under a Medicare practitioner. Comments closed September 14, 2026; final rule expected in November.	Not a standard benefit Available only where a state or managed care plan adds it. The BALANCE Model includes a manufacturer-funded lifestyle program for enrollees in participating states.

State Medicaid coverage now has its own page.

Which states cover GLP-1 medications for obesity changes every budget cycle, so the map moved to a page that is rechecked every week, with a last-verified date, a timeline of every state that switched, and the Arizona details. It also covers employer plans, marketplace plans, TRICARE, and self-pay prices.

Health Policy

The Law That Said No

For twenty years Medicare paid for the heart attacks, the dialysis, and the joint replacements, but not the treatment upstream. One clause explains it.

Since Part D began in 2006, the statute has excluded "agents when used for weight loss" from coverage, borrowing the same exclusion list Medicaid has used since 1990.
The exclusion is about the indication, not the molecule. Part D covers semaglutide and tirzepatide when prescribed for type 2 diabetes (Ozempic, Mounjaro).
Each new label opened a door: Wegovy for cardiovascular risk reduction (March 2024), Zepbound for obstructive sleep apnea (December 2024), Wegovy for MASH (August 2025).
In November 2024 CMS proposed reinterpreting the exclusion so obesity treatment would count as treating a chronic disease. The final rule in April 2025 dropped it.
The workaround is demonstration authority. The GLP-1 Bridge runs outside Part D, funded and administered by CMS directly, so no plan carries risk and the statute is not touched.
Part D's $2,100 out-of-pocket cap for 2026 applies to the comorbidity route. Bridge copays sit outside Part D and do not count toward it.
The November 2025 manufacturer pricing agreements are the financial floor under both the Bridge and the BALANCE Model.

Bottom line

The exclusion is still law. Everything Medicare covers for obesity itself today is either a comorbidity indication or a time-limited demonstration. The question for a patient is not "is it covered" but "which route do I qualify for."

Medicare

The Medicare GLP-1 Bridge

A national demonstration, not a Part D benefit. Real, narrower than the FDA label, and dated.

Runs July 1, 2026 through December 31, 2027. The original end date of December 31, 2026 was extended in spring 2026.
$50 per prescription for Foundayo (orforglipron), Wegovy (injection and tablets), and Zepbound in the KwikPen only. Zepbound vials and single-dose pens are not included.
Tier 1: BMI 35 or higher, no comorbidity needed. Tier 2: BMI 30 or higher plus heart failure with preserved ejection fraction, uncontrolled hypertension (above 140/90 on two or more drugs), or CKD stage 3a or worse. Tier 3: BMI 27 or higher plus prediabetes, prior heart attack, prior stroke, or symptomatic peripheral artery disease.
Age 18 and older. Type 2 diabetes, moderate-to-severe sleep apnea, and noncirrhotic MASH are excluded because Part D already covers those indications.
Must be prescribed with current and ongoing lifestyle modification including structured nutrition and physical activity. The prescriber attests under penalty of perjury.
The pharmacy submits the claim first, then the prescriber completes prior authorization. Decisions within 72 hours. There is no appeal, only resubmission with corrected information.
The $50 does not count toward the Part D deductible or the $2,100 out-of-pocket cap.
KFF estimates about 3.8 million beneficiaries met the criteria in 2023, roughly 8 percent of Part D enrollees.

Bottom line

Bring the numbers to the visit. Eligibility is a grid of BMI against blood pressure, kidney function, A1c, and cardiovascular history, and a patient with BMI 32 and nothing on the list does not qualify even though the FDA label says otherwise.

Behavioral Therapy

Counseling Has Been Covered Since 2011

Medicare's oldest obesity benefit is also its least used. The Bridge's lifestyle requirement gives it a second life.

National Coverage Determination 210.12, effective November 29, 2011: Intensive Behavioral Therapy for obesity, BMI 30 or higher, no copay, no deductible.
Schedule: weekly in month 1, every other week in months 2 through 6, then monthly in months 7 through 12 for patients who have lost at least 3 kg by month 6. Up to 22 visits a year.
Must be furnished by a primary care physician or practitioner in a primary care setting. Specialty clinics cannot bill it, and dietitians cannot bill it directly.
Dietitians, nurses, and other auxiliary staff can deliver the sessions in primary care under practitioner supervision, billed by the practice.
Codes: G0447, individual, 15 minutes. G0473, group of 2 to 10, 30 minutes, added in 2015. Group visits are already covered.
Content follows the 5 A's: assess, advise, agree, assist, arrange.
Uptake in the benefit's first four years was under one percent of beneficiaries with obesity: 3.5 to 7.3 per 1,000 from 2012 to 2015. The primary care restriction and the 15-minute unit are the usual explanations.
Two companion benefits: BMI at the Annual Wellness Visit, and the Medicare Diabetes Prevention Program since 2018 for prediabetes with BMI 25 or higher.

Bottom line

Coverage was never the barrier for counseling. The delivery rules were. The Bridge requires documented, ongoing lifestyle modification, and IBT in primary care is the covered way to deliver and document it.

Nutrition Services

Dietitians: Covered, With an Asterisk

A registered dietitian is a Medicare-covered provider. Whether obesity gets you in the door depends on what else is on the problem list.

Medical nutrition therapy has been a Part B benefit since 2002. Registered dietitians bill it directly for diabetes, non-dialysis chronic kidney disease, and 36 months after a kidney transplant.
3 hours in the first year, 2 hours each year after, more with a physician referral for a change in condition. No cost sharing.
Obesity alone is not a covered MNT diagnosis. Neither is prediabetes.
The overlap is real: Bridge tier 2 includes CKD stage 3a or worse, which does qualify for MNT. Patients on the diabetes route qualify too.
For obesity without those diagnoses, the dietitian reaches the patient through IBT in primary care, delivered under practitioner supervision, or through a Medicare Advantage supplemental benefit.
The Medical Nutrition Therapy Act (H.R. 6199 and S. 3934, 119th Congress) would extend MNT to obesity, prediabetes, hypertension, and other conditions. Introduced, not passed.
The CY 2027 fee schedule proposal would make MNT and diabetes self-management training stand-alone billable visits in Rural Health Clinics, matching FQHCs.

Bottom line

Dietitian services are covered by Medicare when a diabetes or kidney diagnosis is attached, and reachable through primary care for obesity itself. The clean, direct obesity nutrition benefit is still a bill in Congress.

On the Horizon

What Is Proposed for 2027

Next year's expansion is coaching and group delivery, not a new drug benefit. Nothing below is final until the rule is.

The CY 2027 Physician Fee Schedule proposed rule was released in July 2026. Comments close September 14, 2026. If finalized in the fall, changes take effect January 1, 2027.
CMS proposes national payment for health and well-being coaching: CPT 0591T (individual, initial), 0592T (individual, follow-up), and 0593T (group of two or more). Since 2024 these have been temporary telehealth codes without national pricing.
Coaches would furnish the service as auxiliary personnel under a Medicare-enrolled practitioner. A community-based organization pathway under general supervision is proposed for credentialed coaches.
Group obesity counseling is not new. G0473 has existed since 2015. What is new is paying for a coaching model that primary care can staff.
The BALANCE Model's Part D component was delayed indefinitely on April 21, 2026. There will be no negotiated-price Part D program in 2027. The Bridge carries drug coverage through December 2027.
Outside Medicare, CDC-funded Family Healthy Weight Programs are being implemented by 57 organizations in more than 30 states: at least 26 contact hours over 2 to 12 months for children 2 to 18 and their caregivers.
Also proposed: MNT and diabetes self-management training as stand-alone visits in Rural Health Clinics.

Bottom line

If the rule finalizes, 2027 adds a paid coaching workforce and group delivery to the lifestyle side of obesity care. The drug side after December 31, 2027 is empty unless the statute changes or the Part D model is revived.

Medicaid

Medicaid Is a Different Rulebook

Medicare is one national answer that expires in 2027. Medicaid is fifty-one answers that change every budget cycle.

Weight-loss agents sit in Medicaid's optional exclusion list (§1927(d)(2)(A)). Each state decides whether to cover them for obesity.
Every state must cover GLP-1s for type 2 diabetes under the drug rebate program. Prior authorization is allowed.
The number of states covering obesity has been falling since late 2025, with several states ending coverage and a few adding it. The current count, the map, and every change are on the live Insurance Coverage page, rechecked weekly.
Gross Medicaid GLP-1 spending rose from about $1 billion in 2019 to nearly $9 billion in 2024, mostly for diabetes.
The BALANCE Model offers states a negotiated net price plus a manufacturer-funded lifestyle program. States can join through January 1, 2027; it runs through December 31, 2031.
Bariatric surgery: some coverage in 48 states (2022). Children under 21 get medically necessary obesity care through EPSDT.

Bottom line

For Arizona, the answer today is yes for diabetes, yes for cardiovascular risk with prior authorization, and no for obesity itself. The state is not waiting on evidence. It is waiting on a vote.
