Summary
Illinois Department of Healthcare and Family Services will reimburse participating pharmacies $6.40 for H1N1 vaccine administration to Medicaid clients. Pharmacies must bill both the vaccine NDC and administration fee on the same claim, but will only receive payment for the administration fee since vaccine costs are federally subsidized.
Action Required
This policy is from 2009 and applies only to Illinois pharmacies administering H1N1 vaccines to Medicaid clients. Medical practices should note this is historical guidance that is no longer relevant for current billing operations.
