Post-acute rehabilitation services (PARS) for Traumatic Brain Injury (TBI) and Spinal Cord Injury (SCI) are advanced rehabilitation services provided through an interdisciplinary team approach to people who have a TBI, TSCI, or both. For residential services, the consumer must have a TBI or a TBI with a TSCI; and for non-residential settings, the consumer may have a TBI or TSCI. Services are based on an assessment of the individual's assessed deficits. The goal of PARS is to achieve independence in the home and community and/or establish new patterns of cognitive activity or compensatory mechanisms.

Before issuing a service authorization for post-acute rehabilitation services, the counselor must obtain a pre-admission evaluation and written prescription or a physician’s recommendation for needed specific therapies. A post-acute rehabilitation services facility-based provider conducts the pre-admission evaluation. A medical professional provides the prescription or physician’s order.
