Ohio Rev. Code § 5164.755
The medicaid director, in rules adopted under section 5164.02 of the Revised Code, may establish and implement a supplemental drug rebate program under which drug manufacturers may be required to provide the department of medicaid a supplemental rebate as a condition of having the drug manufacturers' drug products covered by the medicaid program without prior approval. The department may receive a supplemental rebate negotiated under the program for a drug dispensed to a medicaid recipient pursuant to a prescription or a drug purchased by a medicaid provider for administration to a medicaid recipient in the provider's primary place of business.
If the director establishes a supplemental drug rebate program, the director shall consult with drug manufacturers regarding the establishment and implementation of the program.
