After the initial evaluation of the extent of the disorder or illness, if the restoration
                  potential is judged insignificant or, after a reasonable period of trial, the patient's
                  response to treatment is judged insignificant or at a plateau, an appropriate functional
                  maintenance program may be established. The specialized knowledge and judgment of
                  a qualified speech pathologist may be required if the treatment aim of the physician
                  is to be achieved; e.g., a multiple sclerosis patient may require the services of
                  a speech pathologist to establish a maintenance program designed to fit the patient's
                  level of function. In such a situation, the initial evaluation of the patient's needs,
                  the designing by the qualified speech pathologist of a maintenance program which is
                  appropriate to the capacity and tolerance of the patient and the treatment objectives
                  of the physician, the instruction of the patient and supportive personnel (e.g., aides
                  or nursing personnel, or family members where speech pathology is being furnished
                  on an outpatient basis) in carrying out the program, and such infrequent reevaluations
                  as may be required, would constitute covered speech therapy. After the maintenance
                  program has been established and instructions have been given for carrying out the
                  program, the services of the speech pathologist would no longer be covered, as they
                  would no longer be considered reasonable and necessary for the treatment of the patient's
                  condition and would be excluded from coverage under section 1862(a)(1).
