                  CORF services, Prosthetic devices are defined as devices that replace all or part
                  of an internal body organ or external body member (including contiguous tissue) or
                  that replace all or part of the function of a permanently inoperative or malfunctioning

               Coverage of a prosthetic device includes all services necessary for formulating its
                  design, material, and component selection; measurement, fittings, static and dynamic
                  alignments; and instructing the patient in its use. Such coverage is included as an
                  integral part of the fabrication of the device.
               
               Orthotic devices are those orthopedic appliances or apparatus used to support, align,
                  prevent, or correct deformities, or to improve the function of moveable parts of the
                  body. As with prosthetic devices, the coverage of an orthosis includes its design,
