  • Self-administered drugs (SAD) are outpatient prescription drugs that Medicare beneficiaries are able to take at home without assistance from a health care professional person. This means they dispense medical services (drug administration) on their own.

  • Medicare does not cover the majority of SAD. However, there are a few exceptions for drugs that are covered by Medicare Part B.

  • Supplemental Medicare plans such as Medicare Advantage plans, Medigap plans, etc. assist with coverage and cost of certain drugs. To know which self-administered medication Medicare covers, one should always check their plan’s formulary for the particular drug they need coverage for.

  • A wide range of programs is available to provide additional cost assistance for prescription drug costs on self-administered medications.

What’s Considered a Self-Administered Drug”?

At times, outpatient hospital treatments require patients to use self-administered prescription drugs or biologicals, such as Tylenol. Drugs or biologicals are deemed self-administered” because the patient can take them or use them without assistance from health care industry professionals. At times, self-administered drugs are abbreviated SAD” for convenience.

Difference Between Conventional Drugs and Biologicals

The term biological” is an umbrella term that encompasses a vast range of products from vaccines, allergenics, gene therapy, and more. These products tend to be more complex than standard prescription drugs as their structures are not easily identified or characterized. Most biologicals are heat sensitive and highly susceptible to microbial contamination, causing them to be manufactured differently than standard drugs.

Criteria for Labeling a Drug Self-Administered”

In order for a drug to be labeled self-administered,” it is evaluated via route of administration, status of condition, and frequency of administration.

  • Route of Administration: Essentially, this factor determines how the drug will be administered to the beneficiary. Intravenous, intramuscular, and subcutaneous administrations are often not deemed self-administered”. However, drugs that can be administered orally, topically, or suppository are usually self-administered.

  • Status of Condition: When determining whether a drug can be self-administered, providers will evaluate how long the condition or treatment is expected to last. Acute” conditions are expected to last less than two weeks while chronic” conditions are expected to last longer than 2 weeks.

  • Frequency of Administration: Another aspect that is looked at in evaluation is how often the drug would be administered to the beneficiary. Infrequent” is viewed as being a monthly administration while frequent” is when a drug needs to be administered once or more times weekly.

Does Medicare Cover Self-Administered Drugs

In short, Medicare does not usually cover self-administered drugs for beneficiaries. However, in certain circumstances with outpatient procedures, self-administered drugs may be covered.

Note: For Medicare regulations related to drugs and for a full list of all the drugs, self-administered or not, covered by Original Medicare, visit this source.

Part A (Hospital Coverage)

Medicare Part A (hospital coverage) works to cover any inpatient services a beneficiary receives including any medication taken while spending time in a hospital, skilled nursing facility, or other inpatient settings. 

Outpatient medications prescribed upon leaving the facility will not be covered under Part A.

Part B (Medical Coverage)

Unlike Part A, Part B coverage may include a select list of medication. Medicare Part B (medical coverage) is used to cover outpatient treatment, procedures, and medical services such as:

  • Annual Provider Visits

  • Necessary Medical Screenings

  • Diagnostic Tests

In most cases, Part B does not cover self-administered drugs or biologics. However, while visiting an emergency room, observation stay, or outpatient surgery center, one may receive medications to take during their stay. The cost of the medications taken during one’s visit may be reimbursed if the beneficiary files a claim. 

In order to receive Medicare Part B coverage, a beneficiary must sign-up and pay a monthly premium. From there, Medicare covers 80% of the Medicare-approved cost, leaving beneficiaries to cover a 20% copayment for their outpatient services.

Drugs Covered By Part B

Self-administered drugs are not normally covered by Medicare. However, certain self-administered drugs highlighted by the Medicare statute are covered by Medicare Part B, including:

  • Blood-Clotting Factors

  • Immunosuppressive Therapy Drugs

  • Erythropoietin (used for dialysis patients)

  • Osteoporosis Drugs

  • Select Oral Drugs Used for Cancer Treatment

Drugs Not Covered By Part B

The Centers for Medicare and Medicaid Services (CMS) has highlighted that prescription drugs or biologicals that are self-administered by Medicare beneficiaries more than 50% of the time are excluded from Medicare coverage. The majority of prescription drugs are outlined on the CMS list of SAD cost exclusions.

Medicare Supplement Plans & Self-Administered Drugs

Medicare supplement plans work to assist with the coverage gaps of Original Medicare. While not all supplemental plans cover the cost of prescription drugs, most provide cost assistance with out-of-pocket payments and fees.

Medicare Advantage (MA) Plans

Medicare Advantage plans often referred to as Medicare Part C, bundle Part A and Part B coverage. Most plans also offer additional benefits such as Part D coverage for prescription drugs and coverage for dental, hearing, and/​or vision services. MA plans are provided to beneficiaries through Medicare-approved private insurance companies and therefore have different coverage guidelines than Original Medicare.

Coverage for self-administered drugs will depend on the MA plan a beneficiary has chosen and which drugs are included in that plan’s formulary list. To avoid unwanted costs, beneficiaries should always review their plan’s prescription drug formulary list and/​or speak with a licensed insurance agent from their health insurance company.

Medigap Plans

Medigap plans, also known as MedSupp plans, work to fill the gaps in standard Medicare coverage. Often, Medigap plans do not include coverage for prescription drugs of any kind. However, they are able to assist with copayments and out-of-pocket costs depending on which MedSupp plan is chosen.

To uncover how one’s Medigap plan can assist with uncovered Medicare costs and fees, a beneficiary should speak with a licensed insurance agent from their health insurance company.

Dual Eligibles Plan

A Dual Eligibles plan, sometimes referred to as a D‑SNP or Dual Eligibles-Special Needs Plan, combines Medicare and Medicaid coverage into one health insurance plan. Individuals must be eligible for both federal programs in order to have this Medicare plan. If a beneficiary has a Dual Eligibles plan, Medicare acts as their primary insurance while Medicaid acts as their secondary insurance.

Oftentimes, Medicaid covers the cost of prescription drugs. However, it’s important to review the list of drugs included in one’s formulary in order to avoid any unwanted costs or fees.

Part D Prescription Drug Plans

Medicare Part D plans are available to beneficiaries who want prescription drug coverage. Similar to MA plans, Part D plans are offered to beneficiaries through Medicare-approved private insurance companies.

When it comes to Part D plans and self-administered drugs, most are covered unless they are over-the-counter (OTC) medications like aspirin or laxatives. In order to ensure a drug is covered, one should check their Part D plan formulary or contact an insurance agent from their health insurance company.

It’s important to note that most plans will not cover drugs bought from pharmacies that are out-of-network, this includes medications bought at hospital pharmacies. If a beneficiary uses an out-of-network pharmacy, even if it’s a hospital pharmacy, they may have to pay for the cost of their SAD medication upfront and later submit a claim for reimbursement to their medical insurance.
