Medicare covers Tymlos, but only under specific conditions and through Part D prescription drug plans

Tymlos (abaloparatide) is a bone-building medication prescribed for osteoporosis in postmenopausal women. Medicare Part D covers it, but whether your plan pays for it depends on your specific drug formulary, your pharmacy, and whether your doctor meets prior authorization requirements. Not every Part D plan includes Tymlos on its formulary, and some plans that do cover it may require you to try a different osteoporosis drug first.

The cost you pay out of pocket can vary significantly. Some seniors pay nothing after meeting their deductible; others pay a copay ranging from $35 to $150 per month depending on their plan tier. A few plans place Tymlos in a specialty tier, which means higher copays — sometimes $200 or more per injection. The only way to know what your plan covers is to check your formulary or call your plan's customer service number.

Key Takeaways

  • Tymlos is covered by Medicare Part D, but not all Part D plans include it on their formulary.
  • Your doctor will likely need to get prior authorization from your plan before Tymlos is covered, which typically takes three to five business days.
  • You can check your plan's formulary online or by calling the customer service number on your insurance card to see the exact copay you would pay.
  • If your plan does not cover Tymlos or the copay is too high, you can switch to a different Part D plan during the annual enrollment period (October 15 to December 7).
  • Some drug manufacturers offer copay information programs that can reduce your out-of-pocket cost even if your plan's copay is high.

How to check if your Part D plan covers Tymlos

Your Part D plan publishes a formulary — a list of covered medications — on its website. You can search for Tymlos by brand name or by the generic name abaloparatide. The formulary will show you the tier your plan places it in (usually tier 3 or 4 for specialty drugs), the copay amount, and any restrictions like prior authorization or step therapy.

If you cannot find it online or the website is unclear, call the customer service number on the back of your insurance card. Have your prescription ready so you can tell them the exact dose and frequency your doctor prescribed. Ask specifically: "Is Tymlos covered?" "What is the copay?" and "Does my doctor need prior authorization?" Write down the answers and the date you called.

Do not rely on your pharmacy to tell you coverage details. Pharmacies see only what their system shows at the moment you try to fill the prescription, which may not match your plan's full formulary or may reflect a temporary system lag.

Prior authorization and what it means for your treatment timeline

Most Part D plans require prior authorization before they will cover Tymlos. This means your doctor's office must submit a request to your insurance plan explaining why Tymlos is medically necessary for you. The plan reviews the request and either approves it, denies it, or asks for more information.

Prior authorization typically takes three to five business days, though some plans respond faster. During this time, your prescription cannot be filled. If your doctor's office submits the request on a Friday, you may not hear back until the following Wednesday or Thursday. Plan ahead: ask your doctor to submit the request as soon as they decide to prescribe Tymlos, not after you have filled the prescription.

Some plans also use step therapy, which means they require you to try and fail on a different osteoporosis medication first — usually a bisphosphonate like alendronate (Fosamax) — before they will cover Tymlos. If your plan has this requirement, your doctor can sometimes request an exception if there is a medical reason you cannot take the first-line drug. This exception request takes longer, usually seven to ten business days.

What to do if your plan does not cover Tymlos or the copay is too high

If your current Part D plan does not cover Tymlos or places it in a tier with a copay you cannot afford, you have options. During the annual enrollment period (October 15 to December 7 each year), you can switch to a different Part D plan that does cover Tymlos at a lower copay. Use the Medicare Plan Finder tool on Medicare.gov to compare plans in your area and see which ones include Tymlos and at what cost.

If you are outside the enrollment period and your plan just denied coverage or your circumstances have changed, you may be able to make a change if you have a may have access to life event — such as moving to a new state, losing other health coverage, or becoming newly may be able to access for Medicare. Contact Medicare at 1-800-MEDICARE to ask whether you may have access to.

Another option is to look into copay information programs. The manufacturer of Tymlos (Radius Health) offers a copay card program that can reduce your out-of-pocket cost. You can also contact your state pharmaceutical information program, which helps seniors with high drug costs. Your doctor's office or local Area Agency on Aging can help you find programs you may be able to use.

How Tymlos is administered and what Medicare covers

Tymlos is a once-daily injection that you give yourself under the skin, usually in the thigh or abdomen. Medicare Part D covers the medication itself, but it does not cover the cost of a nurse visiting your home to teach you how to inject it. Some health plans or community health centers offer injection training for free, so ask your doctor where you can learn.

Medicare Part B covers a one-time demonstration of how to use the injection device if you receive it in a doctor's office or outpatient clinic. If your doctor's office provides the training, ask whether they bill Medicare Part B for it so you understand what you may owe.

Questions to ask your doctor before starting Tymlos

Before your doctor prescribes Tymlos, ask whether they have already checked with your insurance plan about coverage. Ask them to submit the prior authorization request on the same day they write the prescription, not days later. If your plan requires step therapy, ask your doctor whether they think you should try the first-line drug or whether they believe you have a medical reason to skip it and request an exception.

Ask your doctor how long you will take Tymlos — the typical course is two years — and what happens after that. Ask whether they have samples you can use while you wait for prior authorization, so you do not have to delay starting treatment. Finally, ask them to give you the name and phone number of the person in their office who handles insurance requests, so you can follow up if the authorization is taking longer than expected.

When to contact Medicare or your plan if there is a problem

If your plan denies coverage for Tymlos, you have the right to appeal. Your plan must send you a written denial letter explaining why. You have 60 days from the date of that letter to file an appeal. Your doctor can help by submitting additional medical information supporting the need for Tymlos.

If your plan approves Tymlos but your pharmacy says it is not covered when you try to fill it, call your plan's customer service number when ready. There may be a system error, or your pharmacy may not have received the authorization yet. Do not leave the pharmacy without getting a direct phone number to call back — do not accept "we will call you later."

If you have been waiting more than five business days for prior authorization and have not heard back, call your doctor's office and ask them to follow up with the plan. If you have questions about your rights or believe your plan is not following Medicare rules, contact Medicare at 1-800-MEDICARE or visit Medicare.gov.

Frequently Asked Questions

Does Medicare Part A or Part B cover Tymlos?

No. Tymlos is a prescription medication, so it is covered only under Part D. Part A covers hospital stays and Part B covers doctor visits and some outpatient services, but neither covers outpatient prescription drugs.

Can I use a Medigap plan to help pay for Tymlos?

Medigap plans do not cover prescription drugs at all. If you have a Medigap plan, you must have a separate Part D plan to cover Tymlos. Some people have both a Medigap plan and a Part D plan.

What if I have Medicare Advantage instead of Original Medicare?

Medicare Advantage plans include prescription drug coverage (Part D) built in. Check your plan's formulary the same way you would with a standalone Part D plan. Some Medicare Advantage plans cover Tymlos; others do not. You can switch to a different Medicare Advantage plan or to Original Medicare plus a Part D plan during the annual enrollment period.

How much does Tymlos cost without insurance?

The retail price is roughly $4,000 to $5,000 per month, though prices vary by pharmacy and whether you use a discount card. This is why insurance coverage matters so much. If your plan's copay is high, ask about the manufacturer's copay card or your state's pharmaceutical information program.

Can I get Tymlos if I am on Medicaid instead of Medicare?

Medicaid coverage of Tymlos varies by state. Some state Medicaid programs cover it; others do not or require prior authorization and step therapy. Contact your state Medicaid office or your Medicaid managed care plan to ask about coverage.
