Most costs associated with home infusion therapy fall under Medicare Part B benefits. However, keep in mind that insulin pump systems are not considered home infusion therapy and fall under Medicare Part D.  You can read more about Part D plans offering coverage for insulin pumps in our FAQ: Will my Medicare Part D plan cover my insulin pump?

Question:  Which drugs and biologicals are considered "home infusion drugs"?

CMS states:
"'Home infusion drugs' are defined as parenteral drugs and biologicals administered intravenously, or subcutaneously for an administration period of 15 minutes or more, in the home of an individual through a pump that is an item of DME covered under the Medicare Part B DME benefit... '[H]ome infusion drugs' does not include insulin pump systems or self-administered drugs or biologicals on a self-administered drug exclusion list."
