Physician statement/clinical documentation that the member is physically incapable of using regular toilet facilities (for commode coverage).
Documentation that the member is confined to a single room, or confined to one level of the home with no toilet on that level, or confined to the home and there are no toilet facilities in the home (to substantiate need for commode).
Weight documentation (e.g., clinical record showing measured weight) to support extra wide/heavy commode chair (member weighs 300 pounds or more).

Aetna's HMO-based and health network plans generally follow Medicare's criteria for durable medical equipment (DME) items that are used in the bathroom; most DME items used in the bathroom are considered by Medicare to be personal convenience items. Consistent with Medicare rules, Aetna's HMO-based plans consider certain DME toilet items (commodes, bed pans, etc.) medically necessary if the member is bed-confined or room-confined.
Aetna's traditional plans (indemnity, PPO, and Managed Choice POS) consider DME used in the bathroom medically necessary if the DME is primarily medical in nature, not normally of use in the absence of illness and injury, and if it is necessary for daily activities related to health and personal hygiene.
