A seat lift mechanism is covered if all of the following criteria are met:
- The patient must have severe arthritis of the hip or knee or have a severe neuromuscular disease.
- The seat lift mechanism must be a part of the physician’s course of treatment and be prescribed to effect improvement, or arrest or retard deterioration in the patient’s condition.
- The patient must be completely incapable of standing up from a regular armchair or any chair in their home. (The fact that a patient has difficulty or is even incapable of getting up from a chair, particularly a low chair, is not sufficient justification for a seat lift mechanism. Almost all patients who are capable of ambulating can get out of an ordinary chair if the seat height is appropriate and the chair has arms.)
- Once standing, the patient must have the ability to ambulate.
