Medicare's Coverage of Hormone Replacement Therapy

Medicare Part B covers hormone replacement therapy (HRT) when a doctor prescribes it for a medical condition, but the coverage depends on the type of hormone, the delivery method, and whether you meet specific medical criteria. Medicare does not cover HRT prescribed solely for anti-aging or cosmetic purposes. If your doctor determines that HRT is medically necessary—such as for managing menopause symptoms, hormone deficiency, or gender-affirming care—Medicare will typically cover the medication itself through Part D (prescription drug coverage) and any related office visits through Part B.

The actual out-of-pocket cost varies based on your specific Part D plan, your deductible, and which tier the medication falls on. Some HRT medications are generic and cost less; others are brand-name and may require higher copayments. You will need to check your individual plan's formulary (the list of covered drugs) to see exactly what you pay.

Key Takeaways

  • Medicare Part B covers doctor visits related to HRT, and Part D covers the medications themselves if they are prescribed for a medical reason.
  • Coverage is available for estrogen, progesterone, testosterone, and other hormones when medically necessary, but not for cosmetic or anti-aging use alone.
  • Your out-of-pocket cost depends on your Part D plan's formulary, deductible, and the tier assigned to your specific medication.
  • Generic HRT options typically cost less than brand-name versions and are usually covered at a lower copayment.
  • You should review your plan's formulary or call your Part D plan directly to confirm coverage for the specific hormone your doctor recommends.

How Medicare Part B and Part D Work Together for HRT

Medicare Part B pays for the office visit when your doctor evaluates whether you need HRT and monitors your treatment over time. This includes blood tests to check hormone levels and any follow-up appointments. You pay 20 percent of the approved amount after you meet your Part B deductible (which is $240 in 2024, though this amount changes yearly).

Medicare Part D is the prescription drug benefit, and it is where the actual hormone medication is covered. Each Part D plan maintains its own formulary—a list of covered drugs organized into tiers. Tier 1 (generic drugs) usually has the lowest copayment, while higher tiers cost more. Some plans may require prior authorization, meaning your doctor has to get approval from the insurance company before the pharmacy will fill the prescription.

If your plan does not cover the specific HRT medication your doctor prescribed, you have options: you can ask your doctor to prescribe a different medication that is on your plan's formulary, request a coverage exception from your plan (which your doctor can submit on your behalf), or pay out of pocket for the non-covered drug.

Types of Hormone Replacement Therapy Medicare Covers

Medicare covers estrogen therapy in multiple forms: pills, patches, creams, and vaginal inserts. Estrogen is covered when prescribed for menopause symptoms (hot flashes, night sweats, vaginal dryness) or for hormone deficiency. Progesterone (often given alongside estrogen to reduce the risk of uterine cancer) is also covered under the same conditions.

Testosterone replacement is covered for people with documented testosterone deficiency (low T), which is confirmed by blood tests. This includes gels, injections, patches, and pellets. Thyroid hormone replacement (levothyroxine) is covered for hypothyroidism and other thyroid conditions. Other hormones—such as DHEA or compounded bioidentical hormones—may have limited or no coverage depending on your specific plan and whether they are FDA-approved.

Gender-affirming hormone therapy (estrogen for transgender women, testosterone for transgender men) is covered by Medicare when prescribed by a doctor as part of a documented treatment plan. This represents a significant shift in Medicare policy and applies regardless of age.

What Affects Your Out-of-Pocket Costs

Your Part D plan's formulary tier is the biggest factor in what you pay. A generic estradiol pill might cost $5 to $15 per month, while a brand-name patch could cost $50 to $100 or more. If you have not yet met your deductible, you may pay the full cost of the medication until the deductible is satisfied, after which your copayment applies.

The coverage gap (also called the "donut hole") affects how much you pay once you and your plan have spent a certain amount on drugs in a calendar year. In 2024, once combined spending reaches $5,850, you enter the gap and pay a higher percentage of drug costs until spending reaches $7,050, at which point catastrophic coverage begins and your costs drop again. Generic drugs have lower costs in the gap than brand-name drugs.

Income-based subsidies may lower your costs if you may have access to. If your income is below 150 percent of the federal poverty level, you may be may be able to access for the Low-Income Subsidy (LIS) program, which reduces your deductible, copayments, and gap costs significantly.

How to Find Out What Your Plan Covers

The fastest way to confirm coverage is to call your Part D plan directly. Have your doctor's name and the specific medication name and dose ready. The plan representative can tell you the copayment amount, whether prior authorization is needed, and whether the medication is in stock at your preferred pharmacy.

You can also visit your plan's website and search the formulary yourself. Most plans allow you to search by drug name and see which tier it falls on. If you do not have a Part D plan yet, you can compare plans during the annual enrollment period (October 15 to December 7 each year) using the Medicare Plan Finder tool on Medicare.gov. You can filter by specific medications to see which plans cover them at the lowest cost.

If your current plan does not cover your medication well, you can switch to a different Part D plan during open enrollment. You are not locked into the same plan year after year.

Prior Authorization and Coverage Exceptions

Some Part D plans require prior authorization for certain HRT medications, especially brand-name versions or less common formulations. Prior authorization means your doctor must submit a request to the insurance company explaining why the medication is medically necessary. This usually takes a few business days, and the plan will either approve it, deny it, or ask for more information.

If your plan denies coverage or places a medication on a higher tier than you expected, you can request a coverage exception. Your doctor submits this request, explaining why this specific medication is necessary for your treatment. The plan must respond within 72 hours for urgent requests or 7 days for standard requests. If the plan denies the exception, you have the right to appeal.

Generic Versus Brand-Name HRT Options

Generic HRT medications are chemically identical to brand-name versions and work the same way in your body. They cost significantly less—often 50 to 80 percent less than brand-name drugs. Most Medicare Part D plans place generic hormones on Tier 1, the lowest copayment tier. Common generic options include estradiol pills, estradiol patches, and testosterone gels.

Brand-name medications like Premarin (conjugated estrogens), Estrace (estradiol), or Androgel (testosterone) are placed on higher tiers and cost more. Some people prefer brand-name versions because they believe they work better or have fewer side effects, but clinical evidence does not support this for most HRT medications. If your doctor recommends a brand-name drug, ask whether a generic alternative exists and whether switching would lower your cost.

Frequently Asked Questions

Does Medicare cover HRT for transgender people?

Yes. Medicare covers gender-affirming hormone therapy (estrogen for transgender women, testosterone for transgender men) when prescribed by a doctor as part of a documented treatment plan. This applies regardless of age. Coverage includes the medications through Part D and related doctor visits through Part B.

What if my doctor prescribes a compounded bioidentical hormone?

Compounded bioidentical hormones are custom-made by a pharmacy and are not FDA-approved. Medicare coverage for compounded hormones is limited and varies by plan. Most Part D plans do not cover them, or cover them only with prior authorization and a higher copayment. Ask your doctor whether an FDA-approved generic or brand-name option would work instead, as these are almost always covered at a lower cost.

Do I have to pay for HRT during the coverage gap?

Yes, but the amount depends on whether your drug is generic or brand-name. In the coverage gap, you pay 25 percent of the cost of brand-name drugs and a smaller percentage for generic drugs. If you may have access to for the Low-Income Subsidy, your copayment remains the same throughout the year, including in the gap.

Can I switch Part D plans if my current plan stops covering my HRT medication?

Yes, but only during the annual enrollment period (October 15 to December 7). If your plan removes a medication from its formulary mid-year, you may be able to request a Special Enrollment Period, which allows you to switch plans outside the normal window. Contact Medicare at 1-800-MEDICARE to ask about this option.

Will Medicare cover HRT if I am under 65?

Medicare covers HRT for people under 65 only if they may have access to for Medicare through disability, end-stage renal disease, or ALS (Lou Gehrig's disease). If you are under 65 and do not have Medicare, you would need to explore coverage through your employer's health plan, the Marketplace, or Medicaid (which varies by state).
