Teaching individuals with neurological or musculo-skeletal disorders to ambulate with or without an assistive device. Gait training is considered medically necessary for training individuals whose walking abilities have been impaired by neurological, muscular or skeletal abnormalities or trauma. Gait training is not considered medically necessary when the individual’s walking ability is not expected to improve. Provider supervision of repetitive walk-strengthening exercise for feeble or unstable patients is not considered medically necessary. Gait training is not considered medically necessary for relatively normal individuals with minor or transient abnormalities of gait who do not require an assistive device; these minor or transient gait abnormalities may be remedied by simple instructions to the individual.
