Each plan for prescription drug coverage must give you at least a standard level of coverage that is set by Medicare. All plans can vary the cost of prescription drugs they cover (this is their formulary) and how they place drugs into a tier on their formulary.
Each Medicare Part D prescription drug plan provider decides which drugs not to cover on its formulary, these categories of drugs are usually not covered but a plan may decide to put it on their formulary.
- Over-the-counter drugs (non-prescription drugs)
- Weight loss or weight gain drugs
- Drugs for cosmetic purposes or hair growth
- Drugs for sexual or erectile dysfunction
- Drugs when used to promote fertility.
- Drugs when used for the relief of cough or cold symptoms.
- Prescription vitamins and minerals (except for prenatal vitamins and fluoride preparations).
Medicare Part D also does not cover any drugs that are covered under Medicare Part B.
