Medicare can cover an IUD for medical reasons, but only in narrow circumstances: the device has to be treating a documented condition your regional Medicare contractor recognizes, the IUD has to be a hormonal one, and your provider has to bill the insertion under an unlisted procedure code rather than the standard contraceptive one. Get any of those pieces wrong and the claim gets denied automatically.
Why the Default Answer Is No
Medicare does not pay for contraceptive devices. The standard billing code for IUD insertion, CPT 58300, carries an “N” status on the Medicare Physician Fee Schedule, which means claims submitted under that code are denied without further review.1Centers for Medicare & Medicaid Services. Billing and Coding: IUD (Hormone-Eluting) for Endometrial Hyperplasia – CPT 58999 The denial is triggered by the code itself, not by any review of why the device is being placed.
The workaround comes from regional Medicare Administrative Contractors, the companies that process Medicare claims in each part of the country. At least two contractors, Noridian and First Coast, have issued local coverage articles recognizing that a hormonal IUD can be a legitimate medical treatment in specific situations. When the criteria are met, providers bill the procedure under CPT 58999, an unlisted procedure code, and Medicare will consider the claim on its merits.1Centers for Medicare & Medicaid Services. Billing and Coding: IUD (Hormone-Eluting) for Endometrial Hyperplasia – CPT 58999
There is no national coverage determination for medical use of IUDs. Coverage depends on where you live and which contractor handles your region.
The Diagnosis That Qualifies
The condition established in the existing coverage articles is endometrial hyperplasia without atypia, an abnormal thickening of the uterine lining. Under the Noridian and First Coast articles, a progestin-containing IUD may be covered for a Medicare beneficiary with this diagnosis when the patient is not a reasonable surgical candidate or wishes to preserve fertility.1Centers for Medicare & Medicaid Services. Billing and Coding: IUD (Hormone-Eluting) for Endometrial Hyperplasia – CPT 589992Centers for Medicare & Medicaid Services. Billing and Coding: Treatment of Abnormal Uterine Bleeding
The language is narrow. These articles do not broadly approve IUDs for heavy menstrual bleeding, endometriosis, or general hormone-related complaints. If your provider is recommending an IUD for something other than endometrial hyperplasia without atypia, coverage will depend entirely on whether your regional contractor has issued separate guidance for that diagnosis. Your provider’s office can look this up in the Medicare Coverage Database at cms.gov.
Which IUDs Qualify
Only progestin-containing hormonal IUDs are covered under the existing articles. That includes devices like Mirena and Liletta, which release levonorgestrel. Copper IUDs such as Paragard contain no progestin and are not covered under these medical-use provisions.
The articles specifically reference “hormone-eluting” IUDs. If the device your provider recommends has a lower progestin dose or a different formulation, it is worth confirming with your Medicare contractor that the specific product qualifies before the procedure is scheduled.
What You’ll Pay
When an IUD is approved for a qualifying condition, it is covered under Medicare Part B as a medically necessary outpatient service.3Medicare. What Part B Covers Part B pays for the office visit, the device, and the insertion.
Under Original Medicare, you pay the annual Part B deductible first, which is $283 in 2026.4Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles After that, Medicare pays 80% of the approved amount and you pay 20%. Because CPT 58999 is an unlisted procedure code, the approved amount is set regionally by the contractor rather than by a fixed national fee, so your share can vary. Ask your provider’s billing office for an estimate before the procedure.
If your provider accepts Medicare assignment, they agree to accept the Medicare-approved amount as full payment, and you cannot be billed for the difference between their standard charge and what Medicare allows. If your provider does not accept assignment, you could owe more.
Most Medigap policies pay some or all of the Part B coinsurance. Plans A, B, C, D, F, G, and M pay 100%; Plan K pays 50%, Plan L pays 75%, and Plan N pays 100% except for certain office and emergency room copays.5Medicare. Compare Medigap Plan Benefits
If you have a Medicare Advantage plan, it must cover at least what Original Medicare covers, but the rules around it will differ.6Medicare. Compare Original Medicare and Medicare Advantage Expect network restrictions, likely prior authorization, and a flat copayment structure rather than 20% coinsurance.

Lining Up Coverage Before the Procedure
Getting Medicare to actually pay takes more preparation than a typical Part B visit. Work through this sequence with your provider’s office:
- Confirm the diagnosis on paper. Endometrial hyperplasia without atypia is normally documented through an endometrial biopsy with pathology results in the medical record.
- Have the office check your Medicare Administrative Contractor’s local coverage article for your diagnosis in the Medicare Coverage Database.
- Make sure the insertion will be billed under CPT 58999, not CPT 58300. The standard code will trigger an automatic denial.
- Choose a provider who accepts Medicare assignment so you are not exposed to balance billing.
- Get prior authorization if you are on a Medicare Advantage plan. Even under Original Medicare, a coverage inquiry to the contractor beforehand can catch problems early.
- Ask for an Advance Beneficiary Notice if there is any doubt about coverage. The ABN spells out that you may owe the full cost if Medicare denies the claim, and it gives you the choice to go ahead or not.7Centers for Medicare & Medicaid Services. FFS ABN
The documentation is what carries the claim. The record needs to establish the diagnosis, explain why the patient is not a candidate for surgery or has a clinical reason to avoid it, and identify the hormonal IUD as the chosen treatment. Thin documentation is where most denials start.
If the Claim Is Denied
You have the right to appeal any Medicare denial. Under Original Medicare, the first step is a redetermination filed with your Medicare Administrative Contractor within 120 days of the initial denial notice. If that goes against you, there are four further levels of appeal available.8Medicare. Filing an Appeal
Before you file, ask your provider for anything that strengthens the case: pathology reports, clinical notes explaining why surgery was not appropriate, and any medical literature supporting a hormonal IUD for your condition. Your State Health Insurance Assistance Program offers free help with Medicare appeals; you can find your local SHIP at shiphelp.org.8Medicare. Filing an Appeal
If you are on Medicare Advantage, the appeal goes through your plan, not the contractor. The plan is required to send you written instructions on how to file, and the details are in your plan materials or available at the number on your membership card.
