Understanding Part D Exclusions

Drugs Medicare Doesn’t Cover | Understanding Part D Exclusions

Medicare doesn’t cover all prescription drugs ─ and there are specific guidelines on which drugs are NOT covered.  Typically, exclusions apply for medications that aren’t considered medically necessary or aren’t used for a medically accepted indication.

While Medicare sets standard exclusions, Part D prescription drug plans might offer coverage for some of these medications. If they do, it comes without Medicare’s financial contribution, and the trade-off is a higher plan premium.

Granted that certain plans might offer exceptions, most adhere to the Medicare guidelines.  They choose not to cover these drugs to keep costs and premiums more affordable.  Knowing about these exclusions upfront will help you make informed decisions about which Medicare plan best suits your healthcare needs.


Medicare Coverage: Not Covered
Barbiturates are sedative-hypnotics used mainly for anesthesia, seizures, and insomnia.  Due to abuse potential, these are generally not covered by Medicare unless used to treat specific conditions like epilepsy, cancer, or a chronic mental health disorder.


Medicare Coverage: Not Covered
Benzodiazepines, used for anxiety, muscle spasms, and seizures, typically do not receive coverage from Medicare.  They may be covered when prescribed for conditions covered under Part D restrictions.

Cosmetic Drugs

Medicare Coverage: Not Covered
Drugs solely for cosmetic purposes, such as skin wrinkles or hair growth, are excluded from Medicare coverage because they aren’t considered medically necessary.

Fertility Drugs

Medicare Coverage: Not Covered
Medicare does not pay for fertility drugs.  Though important for assisting reproduction, these medications are excluded because they aren’t deemed necessary for immediate health.

Drugs used to treat sexual dysfunction

Medicare Coverage: Not Covered
Prescriptions for sexual dysfunction aren’t covered by Medicare. These are usually classified as life quality improving rather than life-sustaining treatments.

Weight Loss or Gain Drugs

Medicare Coverage: Not Covered
Medications prescribed for weight loss or gain aren’t covered under Medicare unless the weight condition is part of a diagnosed medical condition, such as hypothyroidism for weight gain or morbid obesity, where the treatment is deemed a medical necessity.

Specific Drug Categories Not Covered

Medicare doesn’t cover some categories of products, including over-the-counter drugs, most vitamins and minerals, and drugs not approved by the FDA.  Understanding these limitations helps ensure you avoid being caught off-guard at the pharmacy.

Over-The-Counter Medications

Medicare typically does not cover the cost of over-the-counter (OTC) medications.  They’ll deny a claim for reimbursement for these items unless they are prescribed by a healthcare provider as part of Medicare Part B.

This includes common OTC medications, such as:

  • Pain relievers, like ibuprofen and acetaminophen
  • Cold and flu medication
  • Allergy and sinus medicine

Sometimes, OTCs are covered for durable medical equipment like a nebulizer.

Prescription Vitamins and Minerals

Medicare doesn’t cover prescription vitamins and mineral products, except in cases where they’re medically necessary.

Examples of non-covered items:

  • Multivitamins for general use
  • Vitamin E and C supplements

One exception is prenatal vitamins or vitamin D analogs for specific conditions.

Non-FDA Approved Drugs

Medicare doesn’t provide coverage for prescription drugs not approved by the U.S. Food and Drug Administration (FDA).

Medicare doesn’t cover:

  • Experimental drugs not yet approved for any use
  • Compounded drugs not approved by the FDA

It’s important to check the FDA approval status of any prescribed medication.

Exceptions for a Medically Accepted Purpose

Medicare may cover medications in certain categories when prescribed for specific, accepted medical purposes.

Smoking Cessation Drugs

Medicare Coverage ─ You may be eligible for smoking cessation medications if prescribed and documented as part of a comprehensive cessation plan.

Drugs to Counteract Severe Weight Loss in AIDS Patients

Medicare Coverage ─ In cases where severe weight loss is a complication of AIDS, medications prescribed to address this issue can be covered.

Drugs to Treat Skin Conditions

Medicare Coverage ─ If your doctor prescribes a drug for a skin condition with a medically accepted indication, Medicare may provide coverage.

Cough Medicines for Conditions Such as Asthma

Medicare Coverage ─ If you suffer from a medical condition like asthma, specific cough medicines prescribed by your healthcare provider may be covered.

Drugs Prescribed for a Different Approved Use

Medicare Coverage ─ Drugs excluded from coverage for a particular use may receive coverage if prescribed for a different, approved medical condition.

Final Thoughts

Remember that certain drugs aren’t covered under Medicare guidelines when reviewing your Medicare coverage.  So, checking if your medication is on your Part D plan’s formulary is crucial.  Plans can differ in the drugs they cover, and they can also change from year to year.  Understanding these nuances will help you navigate your Medicare coverage more effectively.

Like any insurance program, Medicare involves complexities regarding coverage options and costs.  I’m here to help you make informed choices that align with your healthcare needs and financial circumstances.
