DVR staff shall authorize services and goods and approve payment in accordance with the DVR Fee Schedule, which identifies market-based standardized rates of payment and other rate setting procedures for each available vocational rehabilitation service. Rates shall be reviewed periodically and adjusted when needed to ensure that applicants and recipients of services have meaningful choices of vocational rehabilitation service providers. DVR may authorize and approve payment of a fee exceeding standard rates contained in the Fee Schedule when an individual's vocational rehabilitation needs are such that they require a specialized service or service delivery mechanism not typically required by other persons with disabilities within the parameters incorporated into the Fee Schedule. DVR may also exceed the fee schedule in order to offer a service or good within an individual’s home community when appropriate. Documentation supporting the need to exceed the standard rates contained in the Fee Schedule for any service shall be included in the service record.
