ACA Marketplace Plans for 2027: Do Any Cover GLP-1s for Weight Loss?

A few ACA Marketplace plans cover Wegovy or Zepbound for weight loss, but they are rare: KFF found Wegovy covered for weight loss by just 1% of federal Marketplace drug plans in 2024, and every plan that covered an obesity GLP-1 required prior authorization. Diabetes GLP-1s such as Ozempic are far more widely covered, usually with prior authorization or quantity limits. Open enrollment for 2027 coverage on HealthCare.gov runs November 1, 2026 to January 15, 2027, and you need to pick a plan by December 15 for coverage starting January 1.

Dates and prices recorded October 19, 2026. Formularies for 2027 plans can differ from 2026, so verify terms in writing before enrolling.

Why most Marketplace plans exclude weight-loss drugs

Marketplace plans must cover essential health benefits, but each state defines the details through an EHB benchmark plan. For prescription drugs, a plan must cover at least one drug in every United States Pharmacopeia category and class, or as many as the state's benchmark plan, whichever is greater (45 CFR 156.122). Nothing in that floor specifically requires an anti-obesity drug.

North Dakota stands out. CMS approved changes to the state's benchmark in 2023, adding coverage for GLP-1 and GIP drugs used to prevent diabetes and treat insulin resistance, metabolic syndrome or morbid obesity. The change took effect January 1, 2025, for ACA-compliant individual and small-group plans, not large employer plans (North Dakota Insurance Department).

Do not expect quick change elsewhere. In the 2027 payment rule published May 20, 2026, CMS said it had paused review of state applications to change EHB benchmark plans. Starting with plan year 2028, it treats state-required benefits as "in addition to EHB," which means states must pay to defray their cost. CMS says that treatment applies even if the benefit is already part of the state's benchmark plan (Federal Register, 2027 Notice of Benefit and Payment Parameters).

How rare is weight-loss coverage?

The clearest public data come from KFF, which reviewed the formularies of plans on the federally run Marketplaces (HealthCare.gov states) for 2024. It found Wegovy covered for weight loss by just 1% of Marketplace prescription drug plans, and every plan that did cover a GLP-1 for obesity required prior authorization (KFF). KFF's review did not include state-run exchanges, where coverage can differ, and Marketplace formularies change every year.

No federal agency publishes a current state-by-state count of 2026 or 2027 Marketplace plans that cover weight-loss GLP-1s. Plan-level formularies are the only reliable answer, which is why the formulary check below matters more than any national average. Where plans do cover these drugs, expect prior authorization criteria such as a minimum BMI, weight-related conditions and documentation of a diet and exercise program.

Diabetes and other labeled uses are a different story

KFF's 2024 analysis found 82% of Marketplace prescription drug plans covered Ozempic, and almost all plans covering GLP-1s for diabetes used prior authorization, quantity limits or similar rules (KFF). If you have type 2 diabetes, compare the tier and rules for your specific drug across plans.

Some weight-management drugs also carry other FDA-approved uses. Wegovy is labeled to reduce major cardiovascular events in adults with established cardiovascular disease and obesity or overweight, and for certain adults with MASH (Wegovy label). Zepbound is labeled for moderate to severe obstructive sleep apnea in adults with obesity (Zepbound label). A plan that excludes weight-loss use may still cover these uses with prior authorization. Ask the insurer directly, and only pursue a use that genuinely applies to you.

How to check a plan's formulary before you enroll

Every Marketplace plan must publish an "up-to-date, accurate, and complete list of all covered drugs," viewable on its public website without creating an account or entering a policy number (45 CFR 156.122).

1. Write down the exact drug, form and dose (for example, Zepbound KwikPen or Wegovy pill).
2. Open the 2027 formulary for each plan you are considering. Search by brand and generic name (semaglutide, tirzepatide).
3. Note the tier and any codes for prior authorization (PA), quantity limit (QL) or step therapy (ST).
4. Find the plan's PA criteria for your drug. Look for BMI cutoffs, required programs and covered diagnoses.
5. Call the insurer, confirm coverage for your use, and ask for the answer in writing.

If a plan denies a drug that is not on its formulary, federal rules give you an exceptions process. The plan must decide a standard request within 72 hours and an expedited request within 24 hours, and you can request an outside review (45 CFR 156.122).

How metal tier changes your drug cost

Source: HealthCare.gov, health plan categories. Percentages are averages across all care, not a drug's price.

For a covered monthly drug, a lower-deductible gold plan often means steadier costs, while a bronze plan may mean paying the plan's full drug price until the deductible is met. For 2027, Marketplace out-of-pocket maximums are capped at $12,000 for an individual and $24,000 for a family (HealthCare.gov). Lower caps of $4,000 for self-only coverage apply to silver plans with cost-sharing reductions at 100% to 200% of the poverty level (CMS 2027 guidance).

One change helps self-employed buyers: under IRS Notice 2026-5, bronze and catastrophic plans available as individual coverage through an Exchange are treated as HSA-eligible high-deductible plans for months after December 31, 2025 (IRS Notice 2026-5). That lets you set aside pre-tax money for a deductible-phase drug cost or for self-pay.

The fallback: self-pay math

If no plan near you covers your drug for weight loss, manufacturer self-pay is the main brand-name route. Novo Nordisk says Health Exchange (Marketplace) plans are not considered government programs for its offer, so the commercial terms may apply to you (NovoCare). Lilly's card terms require a commercial plan and exclude government programs, but do not mention Marketplace plans by name, so ask Lilly's program line.

Source: NovoCare; LillyDirect. Novo says pricing will be updated after December 31, 2026. Totals exclude needles and fees.

Self-pay purchases do not count toward your plan's deductible or out-of-pocket maximum, according to Novo. That makes premium and deductible size matter less if you expect to self-pay the GLP-1 regardless.

Questions to ask the insurer before enrolling

1. Is my drug on the 2027 formulary, and is it covered for weight management or only other uses?
2. What are the prior authorization criteria (BMI, comorbidities, program participation)?
3. What will one fill cost me before and after the deductible?
4. Do manufacturer copay card payments count toward my deductible?
