Medicare prescription Part D

Medicare.gov - Prescription Drug Coverage (Outpatient)

Since you didn’t give any specifics then this response is pretty general.  Like were these meds some that you normally take at home and just did not have them with you at the outpatient procedure?  If not, why were they given to you in this outpatient setting?

If these drugs were on your Part D plan formulary, then the Part D plan is only gonna pay what is described in the plan for these drugs regardless of where you ge them and the cost is more.  

Again, the purpose of the med is important

• Self-administered drugs in hospital outpatient settings: Under very limited circumstances, Medicare may pay for some self-administered drugs if you need them for the hospital outpatient services you're getting.

• If the Part B-covered drugs you get in a hospital outpatient setting are part of your outpatient services, you pay a copayment for the services. Part B doesn't cover "self-administered drugs" in a hospital outpatient setting. "Self-administered drugs" are drugs you'd normally take on your own.
• If you get prescription drugs that Part B doesn’t cover in a hospital outpatient setting, you pay 100% for the drugs, unless you have Medicare drug coverage (Part D) or other drug coverage. In that case, what you pay depends on whether your drug plan covers the drug, and if the hospital is in your plan’s network. Contact your plan to find out what you pay if you get drugs in a hospital outpatient setting that Part B doesn’t cover.
