Does Medicare cover “Mephyton” (vitamin K1)?
“Mephyton” is a brand name for phytonadione (vitamin K1). Whether Medicare covers it depends mainly on (1) whether you’re using it as a covered drug and (2) which Medicare plan you have (Original Medicare vs. Medicare Advantage, and which Part you’re getting).
Under Original Medicare, prescription drug coverage typically comes through Part D. If Mephyton (phytonadione) is on your Part D plan’s formulary, it is usually covered with the plan’s copay/coinsurance rules. If it’s not on the formulary, you may need a prior authorization or an exception.
If you’re receiving vitamin K in a clinic or hospital setting, coverage can fall under Part A (inpatient) or Part B (outpatient/doctor services) rather than Part D, but that depends on where and how it’s administered.
What you should check to know for sure
To confirm coverage for Mephyton under your exact plan, check:
- Your Part D formulary (or your Medicare Advantage drug list), for “Mephyton” or the generic name phytonadione.
- Whether your plan requires prior authorization or restricts it to certain diagnoses (for example, reversal of warfarin/other anticoagulants).
- Whether it’s being dispensed as an outpatient prescription (Part D) or administered by a provider in a facility (often Part B or Part A).
How to ask your plan (fastest way)
Call your plan or use your member portal and ask:
- “Is Mephyton (phytonadione) covered on my plan?”
- “What is my copay for the specific strength and form (tablet vs. injection)?”
- “Does the pharmacy need prior authorization?”

Important note: “Mephyton” can mean different strengths/forms
Medicare coverage and your cost can vary by:
- strength (mg),
- formulation (oral vs. injection),
- and how it’s obtained (prescription filled by a pharmacy vs. given in a facility).
If you tell me whether you have Original Medicare with Part D or a Medicare Advantage plan, plus the strength (and whether it’s tablets or injection), I can help you pinpoint what Part usually applies and what to ask for when checking coverage.
