Medicare Coverage for Hospital Outpatient Drugs

Medicare Coverage for Hospital Outpatient Drugs

What Does Medicare Part B Cover?

Medicare Part B generally covers care in hospital outpatient settings like:

  • Emergency departments
  • Observation units
  • Ambulatory surgery centers
  • Pain clinics

It also covers certain drugs administered in these settings—such as medications given through an IV.

What About Self-Administered Drugs?

Self-administered drugs are medications you would normally take on your own (e.g., daily pills for blood pressure or diabetes). Part B usually doesn’t cover these when you’re treated in an outpatient hospital setting.

If you receive self-administered drugs in this setting and they aren’t covered by Part B, the hospital may bill you directly.

How Medicare Part D Comes Into Play

If you’re enrolled in a Medicare drug plan (Part D), it may cover these drugs. However, Part D plans:

  • Only cover prescription drugs on their formulary (drug list)
  • Do not cover over-the-counter (OTC) drugs like aspirin or laxatives
  • May require you to pay upfront if the hospital pharmacy doesn’t participate in Part D

After paying, you can submit a claim to your Part D plan for reimbursement.

Tips to Avoid Surprise Costs

  • Check with the hospital ahead of time to see if they participate in Part D.
  • Bring your current medications or a complete drug list when you go to the hospital.
  • You can’t regularly get your self-administered prescriptions through the hospital outpatient or ER as a routine method.

Out-of-Pocket Costs and Reimbursement

If your Part D plan covers the drug:

  • You may still owe any deductibles, copays, or coinsurance
  • You might have to pay the difference between the hospital’s charge and what your plan reimburses
  • These costs will count toward your Part D out-of-pocket maximum

If your plan doesn’t cover the drug, you’ll need to pay the full hospital charge.

What If Your Drug Isn’t Covered?

You can:

  • Request an exception to have the drug covered
  • Appeal your plan’s decision

Check your plan’s enrollment materials or contact your Medicare drug plan at directly for help with appeals.
