This final rule responds to comments we received on an interim final rule relating to payment for customized wheelchairs that was published on December 20, 1991 (56 FR 65995). The interim rule set forth the Secretary's criteria that a wheelchair must meet to be considered a customized item and allowed for a payment for the purchase of customized items based on the carrier's case-by-case determination. This rule establishes the interim rule as a final regulation with one change. The change is based on our review and consideration of the public comments. EFFECTIVE DATE: This final rule is effective on July 30, 1993.
