CareSource covers GLP-1 medications in Ohio for type 2 diabetes, but not for weight loss on its Medicaid plans. On the Marketplace side, several GLP-1s are on the formulary with prior authorization or step therapy. The rules differ sharply depending on which CareSource plan you have and why the drug was prescribed.
CareSource Ohio Medicaid: GLP-1s for Type 2 Diabetes
If you have a CareSource Ohio Medicaid plan, your pharmacy benefits are actually administered through the state’s Single Pharmacy Benefit Manager, which uses the Ohio Department of Medicaid’s Unified Preferred Drug List. The same list and the same prior authorization criteria apply to every Ohio Medicaid member, no matter which managed care organization issued the card.1CareSource. CareSource Ohio Medicaid Preferred Drug List
Three GLP-1s are preferred on the January 2026 list and can generally be filled without prior authorization when there is 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 the medical record or on the pharmacy claim. Coverage is not available for non–FDA-approved uses such as weight loss or prediabetes.2Ohio Medicaid SPBM. Ohio Medicaid Single Pharmacy Benefit Manager Portal
GLP-1s That Require Prior Authorization
Several widely prescribed GLP-1s sit on the non-preferred list and need prior authorization before Ohio Medicaid will pay. Since September 2024 this group has included Ozempic (semaglutide), Rybelsus (oral semaglutide), Mounjaro (tirzepatide), and Bydureon Bcise (exenatide).3Ohio Medicaid SPBM. Ohio Medicaid SPBM Prior Authorization Announcements
Prior authorization requests are decided within 24 hours. Prescribers can submit them electronically through the SPBM portal (which moved to the Agadia PromptPA Portal in April 2026), by fax at 833-679-5491, or by phone at 833-491-0344.2Ohio Medicaid SPBM. Ohio Medicaid Single Pharmacy Benefit Manager Portal
Mounjaro Requires You To Try Ozempic First
Mounjaro carries extra hurdles beyond standard prior authorization. The clinical criteria effective January 2026 require an A1C above 7% and either a 120-day trial of Ozempic with inadequate response, or prescriber documentation of why Ozempic cannot be used.4Ohio Department of Medicaid. Ohio Medicaid 30-Day Change Notice, January 2026 If the problem is tolerance, the chart must show that dietary adjustments, prescription anti-nausea medication, and dose adjustments were each tried for at least 30 days. Reauthorization requires a recent A1C showing improvement.
No Medicaid Coverage for Weight Loss
Ohio Medicaid does not cover any medication prescribed solely for weight loss, and that includes GLP-1s like Wegovy, Zepbound, and Saxenda when used for obesity. The prohibition sits in state regulation: Ohio Administrative Code §5160-9-03(B)(1) lists “drugs for the treatment of obesity” as non-covered, and paragraph (D) specifies that drugs in this excluded category are not even eligible for prior authorization.5Ohio Legislative Service Commission. Ohio Administrative Code §5160-9-03, Pharmacy Services: Covered Drugs and Associated Limitations No prior authorization or exception request can override that exclusion.
The Alliance for Women’s Health and Prevention has urged the state to remove the prohibition from the administrative code.6Alliance for Women’s Health and Prevention. Urging Removal of the Prohibition on Medicaid Coverage for Obesity Medications As of mid-2026, the rule stands.
The Narrow Wegovy Exception
One pathway opened in April 2026. Ohio Medicaid added Wegovy coverage under criteria that are classified as cardiovascular or liver treatment rather than obesity treatment.7Ohio Department of Medicaid. Ohio Medicaid 30-Day Change Notice, April 2026 Wegovy can be authorized for:
- MACE risk reduction in a patient 18 or older with a BMI of 27 or higher, no type 1 or type 2 diabetes (A1C below 6.5%), a documented history of prior heart attack, prior stroke, or symptomatic peripheral artery disease, and current treatment with antiplatelet, lipid-lowering, and blood pressure medications.
- Noncirrhotic MASH (metabolic dysfunction-associated steatohepatitis) with moderate to advanced liver fibrosis in a patient 18 or older, confirmed by liver biopsy within the past 24 months or by two qualifying diagnostic tests.
Authorizations under these criteria last 180 days. Renewal requires at least 5% weight loss from baseline, 80% medication adherence, and condition-specific response criteria.
CareSource Marketplace Plans Follow Different Rules
CareSource’s Marketplace (ACA exchange) plans in Ohio use a separate formulary that is not bound by the Medicaid UPDL or the state’s obesity-drug prohibition. The 2025 CareSource Ohio Marketplace expanded formulary lists Ozempic, Trulicity, Rybelsus, and Mounjaro, each with prior authorization or step therapy.8CareSource. CareSource Ohio Marketplace Plan Documents, 2025 Mounjaro was removed from the Marketplace formulary effective January 2026.9CareSource. CareSource Summary of Formulary Changes Notice
To check whether a specific drug (including Wegovy or Zepbound) is on your Marketplace plan, use the 2026 formulary document or the Price A Medication tool on the CareSource website.10CareSource.

Decisions come within 72 hours, or within 24 hours for urgent conditions.
If Your GLP-1 Is Denied
Your appeal path depends on which plan you have.
Ohio Medicaid and MyCare Ohio
For MyCare Ohio, start by requesting a Coverage Determination. If it is denied, you have 60 days to file a redetermination. Appeals go to Express Scripts (which handles CareSource pharmacy appeals) by mail or fax, or by phone for an expedited request. Standard decisions take seven days; when waiting could seriously harm your health and your prescriber supports the request, an expedited appeal is decided within 72 hours.11CareSource. CareSource MyCare Ohio Pharmacy Redetermination Form If the internal appeal fails, you can request a State Hearing.12CareSource. CareSource MyCare Ohio Grievance and Appeal Information
One caution: because §5160-9-03 bars Medicaid coverage of obesity drugs and bars prior authorization for them, an appeal has little chance when the prescription is for weight loss alone. Appeals are most useful for diabetes-related denials where the clinical criteria can be documented on a second look.
CareSource Marketplace
Marketplace members have 180 calendar days to file a clinical appeal after a prior authorization denial. A pre-service appeal (before the drug is dispensed) needs the member’s written consent. The provider portal is the fastest route. Appeals should include progress notes, records of prior treatments tried, and other supporting clinical information.13CareSource.
