CareSource covers GLP-1 medications in Ohio when they’re prescribed for type 2 diabetes, but not when they’re prescribed solely for weight loss under a Medicaid plan. If you have CareSource Ohio Medicaid, your pharmacy benefit follows a statewide drug list that flatly excludes obesity drugs. If you have a CareSource Marketplace plan, several GLP-1s are on the formulary with prior authorization or step therapy requirements. The specific medication, your diagnosis, and which CareSource plan you have all shape the answer.
GLP-1s Covered for Type 2 Diabetes on Ohio Medicaid
Pharmacy benefits for every Ohio Medicaid member, including CareSource members, run through the state’s Single Pharmacy Benefit Manager and its Unified Preferred Drug List.1CareSource. CareSource Ohio Medicaid Preferred Drug List The same rules and criteria apply regardless of which managed care plan you have.
Three GLP-1s are preferred on the January 2026 UPDL and can generally be dispensed without prior authorization when you have a documented type 2 diabetes diagnosis:2Ohio Medicaid SPBM. Ohio Medicaid Single Pharmacy Benefit Manager Portal
- Byetta (exenatide)
- Trulicity (dulaglutide)
- Victoza (liraglutide)
Since December 2025, even these preferred drugs require the diabetes diagnosis to appear in your medical record or on the pharmacy claim. Coverage is not available for off-label uses such as prediabetes or weight loss.
Non-Preferred GLP-1s That Need Prior Authorization
Several of the most-prescribed GLP-1s are non-preferred and require prior authorization before Ohio Medicaid will pay. Since September 2024, that list includes Ozempic (semaglutide), Rybelsus (oral semaglutide), Mounjaro (tirzepatide), and Bydureon Bcise (exenatide).3Ohio Medicaid SPBM. Ohio Medicaid SPBM Prior Authorization Announcements Your prescriber submits the request through the SPBM portal, by fax at 833-679-5491, or by phone at 833-491-0344, and decisions come back within 24 hours.2Ohio Medicaid SPBM.

Mounjaro Requires Trying Ozempic First
Mounjaro has step therapy on top of prior authorization. The clinical criteria effective January 2026 require an A1C above 7% and either a 120-day trial of Ozempic with an inadequate response or documentation of why Ozempic cannot be used.4Ohio Department of Medicaid. Ohio Medicaid 30-Day Change Notice, January 2026 If you can’t tolerate Ozempic, your chart has to show that dietary changes, prescription anti-nausea medication, and dose adjustments were each tried for at least 30 days. Renewals require a recent A1C showing improvement.
Why Weight-Loss GLP-1s Aren’t Covered Under Medicaid
Ohio Medicaid does not cover any drug prescribed solely for weight loss, and the restriction is written into state regulation. Ohio Administrative Code §5160-9-03 lists “drugs for the treatment of obesity” as non-covered, and specifies that drugs in this excluded category are not eligible for prior authorization.5Ohio Legislative Service Commission. Ohio Administrative Code §5160-9-03, Pharmacy Services: Covered Drugs and Associated Limitations A CareSource Medicaid member cannot get Wegovy, Zepbound, or Saxenda paid for as obesity treatment, and no exception request will override that rule.
The Narrow Wegovy Exception
Effective April 2026, Ohio Medicaid added coverage for Wegovy under two clinical indications that are not classified as obesity treatment:6Ohio Department of Medicaid. Ohio Medicaid 30-Day Change Notice, April 2026
- Reducing risk of major adverse cardiovascular events. You must be 18 or older, have a BMI of 27 or higher, not have type 1 or type 2 diabetes (A1C below 6.5%), and have a documented history of prior heart attack, prior stroke, or symptomatic peripheral artery disease. You also need to be on standard cardiovascular care, including antiplatelet, lipid-lowering, and blood pressure medications.
- Treating MASH (metabolic dysfunction-associated steatohepatitis). You must be 18 or older with noncirrhotic MASH and moderate to advanced liver fibrosis, confirmed by liver biopsy within the past 24 months or by two qualifying diagnostic tests.
Approvals last 180 days. To renew, you need at least 5% weight loss from baseline, 80% medication adherence, and condition-specific response measures.
CareSource Marketplace Plans Have Their Own Formulary
CareSource’s ACA Marketplace plans in Ohio are not bound by the Medicaid UPDL or the state’s obesity-drug prohibition. The 2025 Ohio Marketplace expanded formulary listed Ozempic, Trulicity, Rybelsus, and Mounjaro, all with prior authorization or step therapy.7CareSource. CareSource Ohio Marketplace Plan Documents, 2025 Mounjaro was removed from the Marketplace formulary effective January 2026.8CareSource. CareSource Summary of Formulary Changes Notice
Whether weight-loss-specific brands like Wegovy or Zepbound appear on the Marketplace formulary isn’t confirmed in the source materials available here. Check the current formulary or the Price A Medication tool on the CareSource site.9CareSource.

What To Do If Your GLP-1 Is Denied
Ohio Medicaid and MyCare Ohio
Start with a Coverage Determination. If it’s denied, you have 60 days to file a redetermination (appeal) with Express Scripts, which processes pharmacy appeals for CareSource.10CareSource. CareSource MyCare Ohio Pharmacy Redetermination Form Standard decisions come within seven days; an expedited appeal, supported by your prescriber, can be decided within 72 hours when waiting could seriously harm your health. If the internal appeal is denied, you can request a State Hearing.11CareSource. CareSource MyCare Ohio Grievance and Appeal Information
One caution: because §5160-9-03 bars Medicaid coverage of obesity drugs outright and doesn’t allow prior authorization for them, an appeal won’t succeed if the prescription is written solely for weight loss. Appeals make sense when the denial involves a diabetes-related GLP-1 where the clinical criteria weren’t initially met.
CareSource Marketplace
Marketplace members have 180 calendar days from a denial to file a clinical appeal. Pre-service appeals (before the drug is dispensed) require your written consent. The provider portal is the fastest submission route, and appeals should include progress notes, documentation of prior treatments tried, and other supporting clinical information.12CareSource.
