Marketplace insurance does not have to cover Zepbound, and whether a given plan does depends on your state and the plan. Federal rules set the drug minimum as a count. A plan must cover at least the greater of one drug in every USP category and class, or the same number of drugs in each category and class as the state’s benchmark plan[1]. That is a count, not a list of named drugs, and it does not name weight-loss drugs.
Zepbound is a tirzepatide brand, and Wegovy a semaglutide brand; the same rules decide both. HealthCare.gov says the specific services covered in each benefit category can vary based on your state’s requirements[3]. What the brands cost when a plan says no is in GLP-1 cost without insurance.
The state benchmark sets the floor
Federal regulations define essential health benefits through state-specific benchmark plans, one for each of the 50 states and D.C.[2]. Since plan year 2020 a state may update its benchmark, and CMS lists each state that has[2]. States that did not use that flexibility continue to use the same benchmark plan from plan year 2017[2].
For plan year 2026, CMS approved changes to the Alaska, D.C. and Washington benchmarks, and for 2027 to Colorado’s[2]. These are the most recently approved benchmarks, and each was searched for how it treats weight loss.
| State | Benchmark for | What the benchmark document says |
|---|---|---|
| Alaska | 2026 on | No benefits for "surgical and pharmaceutical treatments of obesity"; the exclusion covers "all obesity drugs and supplements" |
| District of Columbia | 2026 on | Excludes "medical or surgical treatment for obesity, weight reduction"; drugs are not named |
| Washington | 2026 on | Treatment, programs or supplies "intended to result in or relate to weight reduction are not covered", except where federal law requires |
| Colorado | 2027 on | Drug exclusions list "drugs for the treatment of weight control" |
Alaska’s benchmark is the most explicit: its exclusion applies to all obesity drugs and supplements, even if you also have an illness or injury that might be helped by weight loss[4]. Washington’s excludes medical treatment, programs or supplies intended to result in or relate to weight reduction, except where federal law requires it or it is a designated preventive service[5]. It does not name drugs. Colorado’s drug exclusions include drugs for the treatment of weight control[6]. Its 2027 change, approved in December 2024, added coverage for abortion services[7], and the approved document still carries the weight-control exclusion[6].
D.C.’s benchmark excludes medical or surgical treatment for obesity and weight reduction, with exceptions for preventive screening, childhood obesity visits and nutrition counseling[8]. It does not name drugs, so how it applies to a weight-loss prescription is a question for the plan.
How to check a plan before you enroll
Every plan must publish an up-to-date, complete list of covered drugs, with tiers and restrictions such as prior authorization[1]. It must be viewable on the plan’s public website without creating an account or entering a policy number[1].
On HealthCare.gov you can view a list of covered drugs for each plan, and search for prescription drugs while comparing plans; the site then tells you whether each plan covers them[9]. Search for Zepbound by name, then open the plan’s own drug list to see its tier and any prior authorization.
If your plan does not list it
Plans that provide essential health benefits must have a process to request a clinically appropriate drug the plan does not otherwise cover[1]. A standard request is decided within 72 hours and an expedited one within 24 hours, and a denial can go to an independent review organization[1]. If an exception is granted, the plan must treat the drug as an essential health benefit[1]. How that process runs step by step is in Zepbound denied by insurance.
The benchmark documents read here speak of weight loss and obesity. None of them addresses a prescription for another approved use, such as obstructive sleep apnea, so ask the plan how it reads its exclusion for that use. How the other payers answer the same question is in is Zepbound covered by insurance, and whether the maker’s card works with a marketplace plan is in Wegovy savings card. Compounded tirzepatide, a different product from the brand, is compared on the price boards.
