Medicare can cover an IUD when it’s prescribed to treat a specific medical condition, but coverage is narrow and comes with important limitations. The clearest path to approval is through Medicare Part B, which may pay for the device, insertion, and removal when the IUD is used to treat certain uterine conditions rather than as birth control.
What Medical Conditions Qualify
Medicare does not cover IUDs as contraception. Coverage kicks in only when the device is being used as a treatment for a diagnosed medical condition, and the list of qualifying diagnoses is short. The most well-established reason Medicare approves a hormone-releasing IUD is endometrial hyperplasia, a condition where the lining of the uterus grows too thick and can progress toward cancer. CMS coverage policies specifically recognize IUDs as an appropriate treatment for endometrial hyperplasia without atypia, particularly for patients who aren’t good candidates for surgery.
Beyond endometrial hyperplasia, Medicare may also cover an IUD for chronic abnormal uterine bleeding that has persisted for at least six months. The underlying causes of that bleeding can include fibroids, certain precancerous changes, or bleeding caused by other medical treatments. Your medical record needs to clearly document the specific condition causing the bleeding and show that it meets the threshold for chronic abnormal uterine bleeding, not just an occasional irregular cycle.
If your doctor recommends an IUD for something like heavy periods related to perimenopause or general hormone management, coverage is far less certain. The condition needs to map to one of the specific diagnoses that Medicare’s regional contractors have approved.
How Part B Coverage Works
When Medicare does cover an IUD for a medical reason, it falls under Part B (outpatient medical services). Part B pays for the device itself, the insertion procedure, and eventual removal. You’re still responsible for cost sharing: the 2025 Part B annual deductible is $257, and after that, you typically pay 20% of the Medicare-approved amount for the procedure.
There’s an important billing wrinkle worth knowing about. The standard procedure code for IUD insertion is automatically denied by Medicare because it’s classified as a contraceptive service. To get around this, your provider must bill using a different procedure code (CPT 58999) and include a description like “hormone IUD for endometrial hyperplasia” along with the correct diagnosis code on the claim. If your provider isn’t aware of this billing requirement, your claim will likely be rejected even if you have a qualifying medical condition. It’s worth confirming with your doctor’s billing office that they know how to submit this correctly before the procedure.
What About Part D or Medicare Advantage
Medicare Part D (prescription drug plans) rarely covers IUDs. Fewer than 1% of Part D plans included the Mirena IUD in 2024, and among those that did, over 90% placed it on Tier 4, which typically means a copay around $100 just for the device. That cost wouldn’t include the doctor visit or insertion procedure, which Part D doesn’t cover at all.
If you have a Medicare Advantage plan (Part C), your plan must cover at least everything Original Medicare covers. So if Original Medicare would approve a medically necessary IUD under Part B, your Advantage plan should too. However, your cost sharing, network requirements, and prior authorization rules may differ. Some Advantage plans may require pre-approval before the procedure, so check with your plan directly.
Getting Your IUD Approved
The key to Medicare covering your IUD is documentation. Your medical record must clearly show the diagnosed condition, how long you’ve had symptoms, and why the IUD is the appropriate treatment for your situation. For abnormal uterine bleeding, that means documenting at least six months of symptoms along with the underlying cause. For endometrial hyperplasia, your doctor should note the specific type and explain why the IUD is preferable to surgery in your case.
Coverage decisions are made by regional Medicare contractors, not by a single national policy. This means the specific conditions approved and the documentation required can vary slightly depending on where you live. Two of the major contractors, First Coast and Noridian, have published policies specifically approving hormone-releasing IUDs for endometrial hyperplasia. If your region’s contractor hasn’t published a similar policy, your provider may need to submit the claim with supporting medical records and appeal if it’s initially denied.
If your claim is denied, you have the right to appeal. A denial doesn’t always mean the service isn’t covered. It can mean the billing was submitted incorrectly or the documentation didn’t include enough detail. Your doctor’s office can often resolve this by resubmitting with the correct codes and a letter of medical necessity explaining why the IUD is the right treatment for your condition.
