Ohio Rev. Code § 5164.302

(A) Before entering into a provider agreement with a medicaid provider that seeks initial enrollment as a provider of home and community-based services under the medicaid program, the department of medicaid shall conduct an in-person review of the individual or site inspection of the entity seeking enrollment as a provider. The department shall thereafter conduct a subsequent in-person review or site inspection every three years.

(B) The department shall deny, refuse to revalidate, suspend, or terminate a provider agreement if the department determines that an individual or entity seeking enrollment as a provider of home and community-based services under the medicaid program is principally located at the same address as more than six other active home and community-based services medicaid providers or is principally located at the same address as another home and community-based services medicaid provider when the address contains less than one thousand square feet of space.

(C) The department of medicaid shall make a referral to the auditor of state whenever it is determined that a single address is the principal place of business for more than six home and community-based services medicaid providers.
