Ohio Revised Code Title XXXIX. Insurance § 3963.05

(A) The department of insurance shall prescribe the credentialing application form used by the council for affordable quality healthcare (CAQH) in electronic or paper format for physicians. The department of insurance also shall prepare the standard credentialing form for all other providers and shall make the standard credentialing form as simple, straightforward, and easy to use as possible, having due regard for those credentialing forms that are widely in use in the state by contracting entities and that best serve these goals.

(B) No contracting entity shall fail to use the applicable standard credentialing form described in division (A) of this section when initially credentialing or recredentialing providers in connection with policies, health care contracts, and agreements providing basic health care services, specialty health care services, or supplemental health care services.

(C) No contracting entity shall require a provider to provide any information in addition to the information required by the applicable standard credentialing form described in division (A) of this section in connection with policies, health care contracts, and agreements providing basic health care services, specialty health care services, or supplemental health care services.

(D) The credentialing process described in this section does not prohibit a contracting entity from limiting the scope of any participating provider's basic health care services, specialty health care services, or supplemental health care services.

(E) The requirement that the department of insurance prepare the standard credentialing form for all other providers does not include preparing the standard credentialing form for a hospital.
