Will your insurance cover naltrexone? It might. But your specific plan decides.
Your policy affects what you pay. The drug's form plays a role too. Some plans put limits on their payments.
Look at your plan's formulary before you get the script filled. It lists which drugs are covered. It also shows your out-of-pocket costs.

Insurance Coverage for Naltrexone: The Quick Take
Does insurance cover naltrexone? Maybe. There is no one answer for everyone. A plan may cover naltrexone for alcohol use disorder. But no plan, product, or form guarantees coverage.
Only your plan documents show what you get. General drug guides do not confirm your benefits. You need to check the exact formulary and benefit details. This tells you if your insurance coverage for naltrexone includes a specific product.
Having broad prescription-drug benefits does not mean your specific medication is included. Do not use typical cash prices or general estimates to guess your out-of-pocket costs.

FDA-approved medications exist for alcohol use disorder, including naltrexone[2]
These numbers give you context. They do not mean your individual plan covers naltrexone. Individual and small-group plans follow essential health benefit rules. Every type of health coverage does not follow them the same way.[3] Confirm your specific benefits before filling a prescription.
Insurance Coverage for Naltrexone: Oral vs. Injectable
Check that you mean the right drug. Naloxone and naltrexone sound similar. Yet they do very different jobs.
Naltrexone is an opioid antagonist. It works by blocking opioid receptors.[4] Doctors use it for alcohol use disorder. Naloxone is a different drug. It reverses opioid overdose.[5]
Pose clear questions regarding your plan's details. Oral naltrexone tablets are FDA-approved for alcohol dependence.[6] You can learn more about how naltrexone works in our guide on how naltrexone works.
Your plan and the specific product drive coverage. Ask these questions for each type:
| Medication | Use | Who to Ask | Benefit to Check | Notes |
|---|---|---|---|---|
| Generic Oral Naltrexone | Treats alcohol dependence[6] | Pharmacy or Provider | Pharmacy Benefit | May need prior approval. |
| Injectable Naltrexone | Treats alcohol use disorder | Provider or Plan Admin | Medical or Pharmacy Benefit | Ask which benefit applies. Injection fees may be separate. |
| Naloxone | Reverses opioid overdose[5] | Pharmacy or Provider | Varies by Plan | Not for alcohol use disorder. Rules differ from naltrexone. |
For injectables, find out which benefit pays the cost. Some plans use the medical benefit, while others use the pharmacy benefit. Ask about fees for giving the shot, too. Talk to your insurer directly to confirm these details. Rules change often. Our guide to naltrexone injection vs oral covers the safety profiles and side effects of each form.
Naltrexone Cost With Insurance: Factors That Affect Your Bill
Insurance coverage for naltrexone does not lead to one fixed price. Your plan drives the cost. The specific product and the place where you fill it matter too. Get an estimate from your insurer or pharmacy. They can look at your own details.
A few terms decide how much you pay:
- Deductible: This is the amount you cover before insurance kicks in. After you hit this limit, your plan starts paying.
- Copay: This is a flat fee. You pay it every time you pick up a prescription.
- Coinsurance: This is a set percentage of the price. You pay this share after your deductible is met.
People using Medicare Part D should look at tiers. Your share of the cost often rides on the drug's tier in your formulary. The pharmacy you pick also plays a role. These rules shift from plan to plan. They do not promise that a certain product will be covered.
Other charges may pop up if you take naltrexone by injection. The provider or facility might bill for the visit itself. Check if these fees are separate from the drug cost.

Naltrexone Insurance Coverage: How to Verify Benefits
Start with the exact product to check naltrexone insurance coverage for alcohol use disorder. Ask your prescriber for the specific name and form. Do not search for just the drug name. Prices shift by brand and dose.
- Gather your papers. Have your insurance card ready. Get the exact drug name, strength, and form from your prescriber.
- Check the formulary. Look up the exact product on your plan's website. See if it is listed.
- Call your insurer or pharmacy benefit administrator. Ask about coverage and costs. Medicare Part D members can ask their plan for a coverage determination about whether a prescription drug is covered.[7]
- Confirm the final cost. Verify the total with the pharmacy or provider. Do this before you fill the script or book an appointment.
See verify your insurance benefits for broad tips on checking prescription benefits. However, you must confirm the details for each specific medication. These rules shift frequently.
Questions to Ask Your Plan
Your ticks are saved on this device only.
Steps to Take When Insurance Says No
A denial is not a medical judgment. It does not say naltrexone is unsafe for you. Do not alter your treatment plan just because of this letter. Talk to your prescriber first.
If your claim is denied, contact your plan for details. Ask for the exact reason behind the denial. Request the policy or formulary rule that applies. Learn the deadline to file a review. Also ask how to start an internal appeal.
Then talk to your prescriber. Ask if they can share clinical info to support your case. Check if a different covered product works for you. Your prescriber can help you pick the best path forward.
Appeal paths change based on your plan type. Many non-grandfathered plans offer internal appeals and external reviews, but rules depend on your plan and laws.[8] State agencies handle many fully insured plans. Self-funded employer plans usually follow federal ERISA rules.[9] Read your denial notice closely for specific steps. Our guide on appealing a coverage denial offers more help on appealing a prescription coverage denial.
Naltrexone Eligibility: Who Qualifies and What to Do Next
Your doctor picks if naltrexone is right for you. They check your health and your goals. This is a medical call. Getting insurance approval is a different step.
Just because your plan pays for it does not mean it fits you. Both parts need to work together.
Naltrexone can help reduce heavy drinking.[10] For some people, it aids in staying sober.[11] The American Psychiatric Association recommends this drug for those with moderate-to-severe alcohol use disorder. It works best when you want to drink less or stop.[12] To see how your body responds over time, our guide to monitoring alcohol medication progress explains what to watch for. If you slip up while taking naltrexone, our guide to relapse on alcohol medication covers safety steps and next moves.
Do not guess if this drug is right for you. Speak with your doctor first. Your doctor knows your medical history. After that, check what your plan covers to check the costs. Before buying it, always verify the exact price with your insurer.
Frequently Asked Questions
How much is naltrexone with insurance?
There is no single price for all plans. Costs vary by your specific product and benefit tier. They also depend on your pharmacy or provider. For Medicare Part D in 2026, the annual out-of-pocket cap is $2,100.[13] This cap is not a naltrexone price. It does not mean a specific product is covered. Ask your insurer for an estimate based on your plan details.
Will insurance cover generic oral naltrexone and injectable naltrexone the same way?
Not always. Rules often differ between pills and shots. Check if each exact product is covered. Also ask which benefit applies to each one. For Medicare, some drugs given by a clinician may be covered under Part B.[14] This rule applies when specific requirements are met. It does not guarantee coverage for a particular naltrexone product. Ask about any extra provider or administration charges.
How can I find the exact copay and prior authorization requirements?
Use your current plan formulary to look up the drug. Call your insurer or pharmacy benefit manager for help. Give them the exact product and form you need. A Summary of Benefits and Coverage is just an overview. Detailed drug formulary documents may be separate. Prior authorization rules are in those specific plan documents, not general summaries.
What can I do if my insurance denies naltrexone?
Read the denial notice for the reason and appeal steps. Ask your prescriber if more info or another option fits your needs. If you have an ERISA-covered group plan, check the notice right away. The appeal deadline follows that plan’s specific process. Your prescriber can help you gather docs for an appeal if needed.
Why might naloxone not be covered by my insurance?
Do not assume naloxone is always excluded from coverage. A denial may target a specific product or formulation. It could also relate to a specific plan rule. Ask what exact product was reviewed for coverage. Also ask what alternatives are listed in your formulary. Naloxone comes in more than one FDA-approved form. Ask if the decision applies to the exact form you requested.
Who qualifies for naltrexone?
A prescriber must check your health and treatment goals first. Insurance plans may have their own coverage criteria too. Tell your prescriber about any opioids you are taking now. Current use of opioid pain relievers prevents naltrexone use.[15] Do not guess if you qualify from a guide alone. Trust your clinical evaluation for the final answer on suitability.
