Seat Lifts:

Aetna considers seat lift mechanisms medically necessary durable medical equipment (DME) when all of the following criteria are met:

1. The member must have severe arthritis of the hip or knee, or have severe neuromuscular disease; and
2. The seat lift mechanism must be prescribed to effect improvement, or arrest or retard deterioration in the member's condition; and
3. The member must be incapable of standing up from a regular armchair at home; and
4. Once standing, the member must have the ability to ambulate.

Aetna considers seat lift mechanisms experimental and investigational for all other indications.

Medically necessary seat-lift mechanisms are those types that operate smoothly, can be controlled by the member, and effectively assist the member in standing up and sitting down without other assistance. Seat lifts that operate by spring release mechanism with a sudden, catapult-type motion that jolts the member from a seated to a standing position, are considered experimental and investigational.

Note: Coverage is limited to the seat-lift mechanism, even if it is incorporated into a chair.

Patient Lifts:

Aetna considers patient lifts medically necessary DME if transfer between bed and a chair, wheelchair, or commode requires the assistance of more than one person and, without the use of a lift, the member would be bed-confined. Patient lifts are considered experimental and investigational for all other indications.

Examples of brands of medically necessary patient lifts are the Trans-Aid Lift, the Lift-Aid Chamber Lift and the Hoyer Lift.

Notes: Aetna's HMO plans follow Medicare's rules for lift mechanisms, and consider bathroom or toilet patient lifts non-covered convenience items as Medicare considers bathroom and toilet equipment to be convenience items. Aetna's traditional plans consider bathroom or toilet patient lifts medically necessary for members who meet the criteria for patient lifts set forth above.

Aetna considers an electric lift mechanism a non-covered convenience feature.

Non-covered Lifts:

Note: Aetna does not cover the following types of lifts because they do not meet Aetna's contractual definition of covered durable medical equipment (DME):

• Van lifts (used to lift wheelchair into a truck or van)
• Wheelchair lifts or ramps (e.g., Wheel-O-Vator lift) (provides access to stairways or car trunks). 

Aetna does not cover the following types of lifts because they are considered home modifications:

• Platform lifts, stair lifts, and stairway elevators
• Ceiling lifts (patient lifts mounted on tracks that are attached to the ceiling).

This policy was adapted from Medicare Durable Medical Equipment Carrier (DMERC) medical policies on seat lift mechanisms and patient lifts.
