Medicaid covers some weight loss pills, but coverage depends on your state's program and the specific medication
Medicaid does cover certain weight loss medications, but not all of them and not in every state. The medications most likely to be covered are older drugs like phentermine, which has been used for decades. Newer medications like semaglutide (Ozempic, Wegovy) and tirzepatide (Zepbound, Mounjaro) are covered by some state Medicaid programs but not others, and coverage rules change frequently.
Whether your state's Medicaid program will pay for a weight loss pill depends on three things: which medication your doctor prescribes, whether your state's formulary (the official list of covered drugs) includes it, and whether you meet your state's specific requirements for coverage. Some states require documented medical conditions like diabetes or heart disease before they will cover these medications. Others require you to try diet and exercise first, or to have a certain body mass index (BMI).
Key Takeaways
- Phentermine and a few other older weight loss medications are covered by most state Medicaid programs, while newer drugs like semaglutide have spotty coverage that varies by state.
- Your state Medicaid program publishes its formulary online, which lists exactly which weight loss medications are covered and what requirements apply.
- Many state programs require you to have a related health condition like type 2 diabetes, high blood pressure, or heart disease before covering weight loss medications.
- Your doctor can request a prior authorization or exception if a medication is not on your state's formulary, though approval is not may provide.
Which weight loss medications Medicaid typically covers
Phentermine is the weight loss medication most consistently covered across state Medicaid programs. It is an older drug that has been in use since the 1950s and is approved for short-term use (usually 12 weeks or less). Because it is generic and inexpensive, most states include it on their formularies without major restrictions.
Semaglutide and tirzepatide are newer medications that work differently than phentermine. These drugs were originally developed for type 2 diabetes (sold as Ozempic and Mounjaro) but are also approved for weight loss under the brand names Wegovy and Zepbound. Coverage for these medications through Medicaid is expanding but remains inconsistent. Some states cover them for people with diabetes or obesity-related conditions; others do not cover them at all, or only cover the diabetes versions.
Other weight loss medications like orlistat (Xenical), naltrexone-bupropion (Contrave), and phendimetrazine have variable coverage depending on your state. Your state Medicaid program's website lists its current formulary, which is the authoritative source for what is and is not covered.
How to find out what your state covers
The fastest way to learn what your state Medicaid program covers is to visit your state's Medicaid website and search for the formulary or drug list. Each state publishes this information publicly. You can search by medication name to see whether it is covered, what tier it is on (which affects your cost-sharing), and whether any restrictions apply.
If you cannot find the information online, call your state Medicaid program directly. The phone number is on your Medicaid card or on your state's Medicaid website. Have the medication name ready, and ask whether it is covered, whether prior authorization is required, and whether there are any medical requirements you must meet first.
Your doctor's office can also check coverage for you. Many medical practices have staff who specialize in verifying insurance coverage and can tell you within a day or two whether a specific medication is covered under your Medicaid plan.
Medical requirements and restrictions your state may impose
Even if a weight loss medication is on your state's formulary, your state may require that you meet certain conditions before Medicaid will pay for it. Common requirements include having a BMI above a certain threshold (often 30 or higher), having a related health condition like type 2 diabetes or high blood pressure, or having tried diet and exercise for a set period first.
Some states require prior authorization, which means your doctor must submit a request to your Medicaid program before you fill the prescription. The program reviews your medical history and the reason your doctor is prescribing the medication, then approves or denies the request. This process usually takes a few days to a week.
A few states limit how long you can take a weight loss medication or require you to stop and restart coverage periodically. These rules vary widely, so checking your state's specific requirements is essential.
What to do if your state does not cover the medication your doctor recommends
If your doctor prescribes a weight loss medication that is not on your state's formulary, your doctor can request a prior authorization exception. This is a formal request asking your state Medicaid program to make an exception to its usual coverage rules based on your specific medical situation. Your doctor must provide medical justification — for example, explaining why you need this particular medication instead of one that is covered.
Prior authorization exceptions are approved sometimes but not always. Approval depends on the strength of your doctor's medical argument and your state's policies. If your state denies the exception, you have the right to appeal the decision. Your Medicaid program will send you information about how to appeal.
If your state will not cover the medication even after an appeal, you and your doctor can discuss alternatives that are covered, or you can ask about the cost of paying out of pocket. Some pharmaceutical companies offer patient assistance programs that reduce the cost of medications for people who cannot afford them.
Cost-sharing for covered weight loss medications
If your state Medicaid program covers a weight loss medication, you typically pay little to nothing out of pocket. Most state Medicaid programs charge no copay for generic medications like phentermine, or a small copay (usually $1 to $5) for brand-name drugs. Some states have no copays at all for any medication.
The exact amount you pay depends on your state's Medicaid program and the specific medication. Your state Medicaid website or your Medicaid card will show your copay amounts, or you can call your state program to ask.
How coverage differs between regular Medicaid and Medicaid managed care
Some states run Medicaid as a traditional fee-for-service program, while others contract with private insurance companies to manage Medicaid benefits. If you are enrolled in Medicaid managed care, your coverage may differ slightly from the state's main formulary. Your managed care plan publishes its own formulary, which may cover different medications or have different requirements.
If you are in Medicaid managed care, check your plan's formulary first, not your state's general Medicaid formulary. Your plan's materials or website will tell you which formulary to use. If you are unsure whether you are in managed care or traditional Medicaid, your Medicaid card will say, or you can call your state program.
Frequently Asked Questions
Does Medicaid cover Ozempic or Wegovy for weight loss?
Some state Medicaid programs cover semaglutide (Ozempic or Wegovy), but not all. Coverage varies by state and often depends on whether you have type 2 diabetes or another may have access to condition. Check your state's formulary or call your state Medicaid program to find out whether it is covered in your state.
What if I have Medicare instead of Medicaid?
Medicare coverage for weight loss medications is different from Medicaid coverage. Original Medicare does not typically cover weight loss drugs, but some Medicare Advantage plans do. Contact your Medicare plan directly to ask about coverage for the specific medication your doctor recommends.
Can my doctor appeal if Medicaid denies coverage?
Yes. Your doctor can request a prior authorization exception if a medication is denied, or you can file a formal appeal after a denial. Your state Medicaid program will send you information about how to appeal, including deadlines and what documents to submit.
Will Medicaid cover weight loss pills if I do not have a related health condition?
Some states cover weight loss medications for obesity alone, while others require a related condition like diabetes or heart disease. Check your state's formulary or call your state Medicaid program to learn what medical requirements apply.
Do I have to pay anything out of pocket for a covered weight loss medication?
Most state Medicaid programs charge no copay or a very small copay ($1 to $5) for covered medications, including weight loss pills. The exact amount depends on your state and the specific drug. Your Medicaid card or your state's website will show your copay amounts.
