CORF is recognized in Kentucky Medicaid as Provider Type 91. In order to enroll as a CORF with Kentucky Medicaid, see the Kentucky Medicaid Provider Enrollment website.
Covered Services
CORF service providers must provide coordinated outpatient diagnostic, therapeutic, and restorative services, at a single fixed location, to outpatients for the rehabilitation of injured, disabled or sick individuals. Physical therapy, occupational therapy, and speech-language pathology services may be provided in an off-site location.
The following are considered "core" services that a CORF must provide:
- physician CORF service - consultation with and medical supervision of non-physician staff, establishment and review of the plan of treatment and other medical and facility administration activities
- physical therapy services, social or psychological services.
CORFs are surveyed every six years at a minimum.
CORF facilities must meet the coverage provisions and requirements set forth in 902 KAR 020:230 in order to provide covered services. Any services performed must fall within the scope of practice for the provider. Listing of a service in an administrative regulation is not a guarantee of payment. Providers must follow Kentucky Medicaid regulations. All services must be medically necessary.
Non-Covered Services
- Services from providers who are not Kentucky Medicaid providers
- Services that are not medically necessary
- Cosmetic surgery
Verifying eligibility

Reimbursement
Reimbursement for CORF is defined in regulation (907 KAR 10:015).
A provider may request coverage for a CPT or HCPCS procedure code by submitting a request in writing to the department which includes necessity, CPT or HCPCS code, and expected reimbursement. Any codes considered experimental are not covered by Kentucky Medicaid.
Duplication of Service
The department shall not reimburse for a service provided to a beneficiary by more than one provider, of any program in which the same service is covered, during the same time period.
Prior Authorizations
Each MCO provides prior authorization for its beneficiaries.
Gainwell Technologies provides prior authorizations for fee-for-service (FFS) beneficiaries. For more information, visit Prior Authorizations.
Claims Submission
Each MCO processes its own claims.
Kentucky Medicaid contracts with Gainwell Technologies to process the Kentucky Medicaid FFS claims. For more information, visit KYHealth-Net.
Coding
Kentucky Medicaid requires CORF providers to bill on a (CMS UB-04) claim form utilizing the following code types where applicable:
- Current Procedure Terminology (CPT) codes, regulated by the American Medical Association (AMA).
- Healthcare Common Procedure Coding System (HCPCS) codes, regulated by the Centers for Medicare and Medicaid Services (CMS).
- Current Dental Terminology (CDT) codes, regulated by the American Dental Association (ADA).
- International Classification of Disease, Tenth Revision, Clinical Modification (ICD-10-CM) codes, maintained by the Centers for Disease Control & Prevention (CDC) and the National Center for Health Statistics (NCHS).
Kentucky Medicaid uses the Medicare National Correct Coding Initiative (NCCI) Procedure to Procedure (PTP) edits, the Medicaid Medically Unlikely Edits (MUEs), and the McKesson Claim Check System to verify codes mutually exclusive or incidental.
Claim Appeals
Appeal requests for denied FFS claims must be submitted to Gainwell Technologies. The request must include the Provider Inquiry Form, reason for the appeal, and a hard copy claim.
Please refer to the member's MCO if appealing an MCO claim.
Timely Filing
Claims must be received within twelve (12) months from the date the service was provided, twelve (12) months from the date retroactive eligibility was established, or six (6) months of the Medicare adjudication date if the service was billed to Medicare.
