Does Medicare cover testosterone therapy? Part D rules

This guide covers Part D (drug plans), what one 2026 Medicare plan asks before it pays, and what to do if the answer is no. For private insurers, see whether TRT is covered by insurance.

Does Medicare Part D cover testosterone?

Original Medicare does not include a drug plan. Drug coverage comes from a stand-alone Part D plan, or from a Medicare Advantage plan that bundles drugs. Either way, a private company runs the plan, and its formulary decides which testosterone products are listed.

So there is no single yes or no. One plan may list testosterone shots and another may not. Our Humana guide shows one published list where generic testosterone cypionate sat in the cheapest tier. Your own plan's list is the one that counts.

When a plan asks for approval first

Even a listed drug can need approval before the plan pays. Medicare explains that plans "may also use prior authorization when they only cover a drug for certain medical conditions, but not others" (Medicare.gov plan rules, read November 10, 2026). Prior authorization means your doctor sends the plan proof, and the plan says yes or no before you fill the prescription.

Testosterone is a common example. Plans often cover it for a diagnosed condition and not for symptoms alone. The same page says plans can also use step therapy, a rule that "requires you first to try a certain, less expensive drug."

What one 2026 Medicare plan asks for

THP Medicare, a Part D plan that uses CVS Caremark for its drug rules, publishes a testosterone enanthate form for plan year 2026. Enanthate is a generic testosterone shot. The form's first question asks whether the drug is for "primary or hypogonadotropic hypogonadism" (THP Medicare form, PY2026, read November 10, 2026). Hypogonadism means the body makes too little testosterone because of a problem in the testicles or in the brain signals that control them.

For a new start, the form asks: "Does the patient have at least two confirmed low morning serum total testosterone concentrations based on the reference laboratory range or current practice guidelines?" For someone already on treatment, it asks about one low morning result from before treatment began.

The form also carries a warning in brackets: "Safety and efficacy of testosterone products in patients with 'age-related hypogonadism' (also referred to as 'late-onset hypogonadism') have not been established." In plain words, a slow drop in testosterone with age, with no medical cause, may not meet this plan's rules.

This is one plan's form, so treat it as an example. Another plan can ask for different tests or cutoffs.

How to check your own plan

These steps take about a day:

1. Find your plan's drug list on its website or in Medicare's plan finder, and search "testosterone".
2. Check the product. Shots, gels and patches can be handled differently.
3. Call the number on your member card and ask: "Is testosterone covered, and does it need prior authorization?"
4. Ask your doctor's office to send the request with your blood test results.

The Endocrine Society, a doctors' group, recommends "confirming the diagnosis by repeating the measurement of morning fasting total T concentrations" (Bhasin et al., J Clin Endocrinol Metab 2018). That is why plans ask for two tests. A doctor reads your results; this guide does not.

If your plan says no

You or your prescriber can ask for an exception. Medicare says "An exception is when a drug plan decides to cover a drug that's not on its drug list, or to waive a coverage rule." Your doctor must send a supporting statement. Our steps to get TRT covered explain denials and appeals. Veterans and military families can read our TRICARE and VA guide.

Online programs do not bill Medicare, so they work only as cash pay. A 2022 study found "the cost of 12 months of intramuscular testosterone treatment was highest via the telemedicine platforms" (Jesse et al., J Sex Med 2022). It covered three platforms and one hospital, so it shows a direction only. If your plan covers a generic shot, a local prescriber may cost you less. If it does not, compare programs on our TRT price table. The top-scored program on our best TRT programs page is Maximus. The full fee breakdown is in the TRT cost guide.

FAQ

Does Medicare cover testosterone therapy?

It can, through a Part D or Medicare Advantage drug plan. Each plan has its own drug list and rules. THP Medicare's 2026 form asks for a diagnosed cause and two low morning blood tests. Check your own plan before the first fill.

Does Medicare Part D cover testosterone?

Some plans list testosterone, often with prior authorization. Medicare says plans use that rule when they cover a drug only "for certain medical conditions." Search your plan's drug list for the exact product, such as a shot or a gel.

Does Medicare cover TRT for low testosterone from aging?

Plan rules often lean against it. THP Medicare's form says safety and efficacy in "age-related hypogonadism" have not been established. A diagnosed medical cause and repeated low morning tests are the usual starting point.

What does Medicare require before it pays for testosterone?

One 2026 plan form asks for a diagnosis of primary or hypogonadotropic hypogonadism and two confirmed low morning total testosterone results. Other plans may differ, so ask your plan which tests and forms it wants.

Can I use an online TRT program with Medicare?

Online programs are cash pay and do not bill Medicare. A program's price is for the program, not a claim to your plan. Compare cash prices on our TRT price table if your plan's rules do not fit you.

How do I appeal if Medicare denies testosterone?

Ask your plan for the denial in writing, then have your doctor request an exception with a supporting statement. Medicare says the prescriber must explain why the drug is medically necessary. Your denial notice lists your plan's deadline.
