Medicare Part B (medical insurance) only covers certain drugs in the outpatient setting. Drugs given by infusion or injection would be examples of covered drugs. Medicare regulations have determined that self administered drugs, or drugs that the patient is able to administer to themselves are not covered by Medicare Part B and the hospital must bill the patient for those charges. Some Part D Plans will reimburse the patient for self administered charges. Please contact your Part D Drug plan for information about how to submit a claim. You may contact the PFS Call Center at 217-245-9541, extension 3123 for an itemized list of any self administered drugs that may appear on your outpatient bill.
