Medicare's Coverage of Zomacton

Medicare Part B covers Zomacton (somatropin) when a doctor prescribes it for specific medical reasons, but only if you meet certain conditions. Zomacton is a human growth hormone used to treat adults with growth hormone deficiency — a condition where your body does not produce enough growth hormone on its own. Medicare will not cover it for anti-aging, weight loss, or athletic performance.

The drug itself is covered under Part B as an injectable medication, which means Medicare pays 80% of the approved amount after you have met your Part B deductible. You pay the remaining 20%, plus any difference between what your doctor charges and what Medicare allows. If your doctor's office administers the injection, you may also pay a separate office visit copay.

If you inject Zomacton at home — which is the most common way to use it — you will need a prescription, and the medication comes from a pharmacy. In this case, coverage shifts to Part D (prescription drug coverage) instead of Part B. Your out-of-pocket cost depends on which Part D plan you have and where Zomacton sits on that plan's formulary, or approved drug list.

Key Takeaways

  • Medicare Part B covers Zomacton injections given in a doctor's office for adults with growth hormone deficiency, and you pay 20% of the approved cost after your deductible.
  • If you take Zomacton at home by self-injection, your Part D prescription drug plan covers it, and your cost depends on your specific plan's formulary and tier.
  • Medicare will not cover Zomacton for weight loss, anti-aging, or any use other than treating growth hormone deficiency diagnosed by a doctor.
  • You must have a documented diagnosis of growth hormone deficiency from a doctor before Medicare will pay for Zomacton in any setting.

How to learn about Your Specific Plan Covers Zomacton

If you receive Zomacton at your doctor's office, call your Medicare Part B carrier — the phone number is on your Medicare card. Ask whether Zomacton is covered for your specific diagnosis and whether your doctor's office is in-network. In-network providers accept Medicare's approved amount as full payment (except for your 20% coinsurance), while out-of-network providers can charge more.

If you will be injecting Zomacton at home, contact your Part D plan directly. The plan's customer service team can tell you whether Zomacton is on the formulary, which tier it is on (tier 1 is usually cheapest, tier 5 is usually most expensive), and what your copay or coinsurance will be. Ask specifically about any prior authorization requirements — many plans require your doctor to submit paperwork proving medical necessity before they will pay.

You can also use the Medicare Plan Finder tool on Medicare.gov to compare Part D plans in your area and see which ones cover Zomacton and at what cost. This tool lets you enter your medications and see estimated yearly costs across different plans during the annual enrollment period (October 15 to December 7).

Prior Authorization and Documentation You May Need

Before Medicare or your Part D plan will pay for Zomacton, your doctor usually must submit proof that you have growth hormone deficiency. This typically means lab work showing low insulin-like growth factor 1 (IGF-1) levels and a documented diagnosis from an endocrinologist or other specialist. Some plans require the doctor to submit a prior authorization form stating why Zomacton is medically necessary for you.

The prior authorization process usually takes 3 to 5 business days. Your doctor's office handles the paperwork, but it is worth calling your plan to confirm they received the request and to ask when you can expect a decision. If the plan denies coverage, your doctor can appeal, and you have the right to appeal as well.

Keep copies of all lab results, your diagnosis letter, and any prior authorization approval from your plan. If you switch plans or if there is a billing dispute later, these documents prove that Medicare or your plan approved the medication for your condition.

What to Do if Medicare Denies Coverage

If your Part B or Part D plan denies coverage for Zomacton, you have the right to appeal. For Part B denials, you can file an appeal with your Medicare carrier within 120 days of the denial notice. For Part D denials, you can appeal to your plan within 60 days.

Before you appeal, ask your doctor whether the denial is based on medical necessity or on a coverage rule. If the plan says Zomacton is not covered for your diagnosis at all, an appeal is unlikely to succeed unless your doctor can provide new evidence. If the plan says you need prior authorization first, your doctor can submit that paperwork instead of appealing.

You can also ask your doctor to request a coverage information from Medicare itself. This is different from an appeal and can sometimes overturn a plan's denial if your doctor argues that the medication is medically necessary even though it is not on the formulary.

Out-of-Pocket Costs and Ways to Lower Them

If you have Original Medicare (Part A and Part B) without a Part D plan, you will pay 20% coinsurance for Zomacton injections given in your doctor's office, after you meet your Part B deductible. The deductible for 2024 is $240 per year. If you inject at home without Part D coverage, you will pay the full pharmacy price, which can be several hundred dollars per month.

If you have a Medigap (supplemental insurance) plan, it may cover some or all of your 20% coinsurance for Part B services. Check your Medigap plan documents or call your insurer to confirm. If you have a Medicare Advantage plan (Part C), check your plan's formulary and cost-sharing rules, as they vary widely.

Some pharmaceutical companies offer patient information programs that reduce the cost of Zomacton if you meet income requirements. Ask your doctor's office or pharmacist whether you may have access to, or contact the manufacturer directly. These programs are separate from Medicare and can help even if Medicare covers part of the cost.

When to Contact Your Doctor or Medicare

Contact your doctor if you have questions about whether Zomacton is the right treatment for your growth hormone deficiency, or if you experience side effects like joint pain, carpal tunnel syndrome, or swelling in your hands and feet. These are known side effects that your doctor needs to know about.

Contact your Medicare plan or your plan's customer service line if you are unsure whether Zomacton is covered under your specific plan, if you receive a bill you think should have been covered, or if your plan denies coverage. Have your Medicare number and prescription information ready when you call.

If you cannot afford Zomacton even with Medicare coverage, talk to your doctor about lower-cost alternatives or about whether a patient information program might help. Do not stop taking Zomacton without talking to your doctor first, as stopping growth hormone treatment suddenly can cause symptoms.

Frequently Asked Questions

Does Medicare cover Zomacton for weight loss?

No. Medicare only covers Zomacton for adults with a documented diagnosis of growth hormone deficiency. Using it for weight loss, anti-aging, or any other purpose is not covered, even if a doctor prescribes it off-label.

Will I pay the same amount whether I get Zomacton at my doctor's office or at home?

No. Office injections are covered under Part B (20% coinsurance after deductible), while home injections are covered under Part D (copay or coinsurance based on your plan's formulary tier). Part D costs vary widely depending on your plan, so compare plans to see which is cheaper for you.

What happens if my doctor's office is out-of-network?

Out-of-network providers can charge more than Medicare's approved amount. You will still pay 20% of what Medicare allows, but you may also owe the difference between the provider's charge and Medicare's approved amount. Ask your doctor's office whether they accept Medicare assignment before your visit.

Can I use a GoodRx coupon or discount card instead of my Medicare plan?

You can, but it is usually not allowed to use both at the same time. If the GoodRx price is lower than your Part D copay, you may be able to use GoodRx instead, but tell your pharmacist you have Medicare so they do not accidentally bill your plan. Ask your pharmacist which option costs less before you decide.

How long does prior authorization take?

Most plans respond to prior authorization requests within 3 to 5 business days. Some plans have expedited review for urgent cases, which can be faster. Ask your doctor's office to request expedited review if you need to start Zomacton right away, and follow up with your plan if you do not hear back within a week.
