Are cholesterol injections covered under Medicare Part B or Part D?

Question

Caroline Johnson · Accepted Answer

Great question, and the honest answer is: it depends on which cholesterol injection you're talking about and, more specifically, who gives you the shot.

Here's the general rule that makes Medicare drug coverage click: medications you give yourself at home go through your drug coverage (Part D or the drug portion of a Medicare Advantage plan). Medications a doctor or nurse administers in the office typically fall under Part B.

Most of the newer cholesterol injections, like the ones you inject yourself at home every couple of weeks with a pen device, fall under Part D. Your cost depends on your plan's drug list and what tier the medication sits on. These are typically brand-name drugs, so they're often on higher tiers, but here's some genuinely good news: Medicare drug coverage now has an annual out-of-pocket cap, which has made these medications far more manageable for people who need them long term.

There's also a newer option given as an injection at your doctor's office just twice a year. Because a medical professional administers it, that one generally falls under Part B instead, which means it's handled like a medical service rather than a pharmacy fill, and your costs work differently.

Why does this matter to you? Two reasons. First, if your doctor is recommending one of these, it's worth asking whether the version you'd take falls under your medical coverage or your drug coverage, because your out-of-pocket costs can look very different between the two. Second, if you're choosing or reviewing Medicare coverage and you take (or expect to take) one of these medications, that absolutely needs to be part of the conversation before you pick a plan, not after.

This is exactly the kind of thing I check when I review someone's medication list. It takes a few minutes and costs you nothing, and it can save you from an expensive surprise at the pharmacy counter.

Most cholesterol-lowering injections, such as Repatha® (evolocumab) and Praluent® (alirocumab), are typically covered under Medicare Part D because they are self-administered prescription drugs. Medicare Part B generally covers medications that are administered by a health care professional in a doctor's office or outpatient setting. Coverage, prior authorization requirements, and out-of-pocket costs vary by Part D plan. If you take a cholesterol injection, reviewing your plan's formulary can help determine your specific coverage and costs.

It depends on which cholesterol injection and how/where it’s administered.

For the common injectable cholesterol medications:

* Repatha (evolocumab) — generally Medicare Part D. It’s a self-administered injection.
* Praluent (alirocumab) — generally Part D for the same reason.
* Leqvio (inclisiran) — generally Medicare Part B because it’s administered by a healthcare professional in a physician’s office or other medical setting. It’s given initially, again at 3 months, then every 6 months.

The easiest rule of thumb is: self-administered prescription injections are usually Part D; provider-administered drugs may be Part B.

Lee Hampton · Answer

It depends on which cholesterol injection they're taking. Most self-injected medications, like Repatha or Praluent, are usually covered under a Medicare Part D drug plan. If the injection is given by a doctor in the office, like Leqvio, it's generally covered under Medicare Part B. It's always a good idea to check the specific medication and the member's plan to be sure.

Usually depends on which injection you're having done. As a rule of thumb I always tell my clients that any drug or injectable you need to go to the doctor's office to have administered, is going to fall under Part B of Medicare. So if you have a supplemental/medigap plan, it's pretty much going to be covered by Medicare and the supplemental plan. 
Any drug or injectable you have that you must administer yourself, will fall under Part D and so it's treated as any other Part D drug, so there might be deductibles, co-pays, etc.

William Brobson · Answer

Yes, cholesterol-lowering injections are covered by Medicare.  Primarily through Part D.  Including Medicare advantage plans that have a prescription drug plan with them.

Kenneth Roberts · Answer

Cholesterol‑lowering injections can be covered under Medicare Part B or Part D, depending on which drug it is and how it’s administered. The distinction matters , because your costs can be very different under each part.
