Comprehensive Outpatient Rehabilitation Facilities Services (CORF) is identified in Kentucky Medicaid as Provider Type (91). To enroll and bill Kentucky Medicaid, CORF service providers must be:
- be enrolled with Medicare
- Licensed in the state in which they operate. In Kentucky, hospitals must contact the Office of Inspector General, Division of Health Care for a survey/license.
- Enrolled as a Medicaid active provider and, if applicable, enrolled with the managed care organization (MCO) of any beneficiary for whom it provides services.
CORF is limited to Medicare deductible and coinsurance payments for Qualified Medicare Beneficiary (QMB). A facility enrolls under a separate provider number as a CORF provider to bill for deductible and coinsurance amounts applicable to QMB beneficiary receiving services covered under the CORF program.
CORF serve 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.
