Description

This document addresses seat lift mechanisms, assistive devices used in the home to lift a person’s body from a sitting position to a standing position or to lower the individual from a standing to a sitting position.

This document does not address powered seat elevation systems used for powered wheeled mobility devices (see CG-DME-31).

Note: Please see the following related documents for additional information:

• CG-DME-10 Durable Medical Equipment
• CG-DME-23 Lifting Devices for Use in the Home
• CG-DME-31 Powered Wheeled Mobility Devices

Clinical Indications

Medically Necessary:

A seat lift mechanism is considered medically necessary when all the following criteria are met:

1. The individual must have severe arthritis of the hip or knee(s) or have a severe neuromuscular disease; and
2. The seat lift mechanism must be a part of the prescribed course of treatment; and
3. The individual must be completely incapable of standing up from a regular armchair or any chair in their home; and
4. Once standing, the individual must have the ability to ambulate.

Note: Documentation that an individual has difficulty or is even incapable of getting up from a chair, particularly a low chair, is insufficient justification for a seat lift mechanism. Most individuals who are capable of ambulating can raise up out of an ordinary chair if the seat height is appropriate and the chair has arms.

Not Medically Necessary:

1. A seat lift that operates by spring release mechanism with a sudden, catapult-like motion and jolts the individual from a seated to a standing position is considered not medically necessary.
2. A seat lift mechanism is considered not medically necessary when the criteria listed above are not met.

Discussion/General Information

Individuals with impaired mobility often require physical assistance in lifting and transferring. Numerous medical conditions (such as, arthritis, muscular dystrophy, and neuromuscular diseases) can lead to limited mobility as a result of pain, joint stiffness or muscle weakness. Individuals are often not able to move from a sitting position to a standing position without the assistance of another person or a device. Devices such as seat lift mechanisms have been employed to ease transfers and prevent injuries to the individual, caregiver, or both (CMS, 2005). The seat lift mechanism assistive devices are utilized in the individual’s home or place of residence. In establishing medical necessity for the seat lift, the Centers for Medicare and Medicaid Services (CMS) states the seat lift must be included in the physician's course of treatment, that it is likely to affect improvement or arrest or retard deterioration in the individual's condition, and that the severity of the condition is such that the alternative would be chair or bed confinement (CMS, 1989).

History

Status

Pre-Merger Organizations

Federal and State law, as well as contract language, and Medical Policy take precedence over Clinical UM Guidelines. We reserve the right to review and update Clinical UM Guidelines periodically. Clinical guidelines approved by the Medical Policy & Technology Assessment Committee are available for general adoption by plans or lines of business for consistent review of the medical necessity of services related to the clinical guideline when the plan performs utilization review for the subject. Due to variances in utilization patterns, each plan may choose whether to adopt a particular Clinical UM Guideline. To determine if review is required for this Clinical UM Guideline, please contact the customer service number on the member's card.

Alternatively, commercial or FEP plans or lines of business which determine there is not a need to adopt the guideline to review services generally across all providers delivering services to Plan’s or line of business’s members may instead use the clinical guideline for provider education and/or to review the medical necessity of services for any provider who has been notified that his/her/its claims will be reviewed for medical necessity due to billing practices or claims that are not consistent with other providers, in terms of frequency or in some other manner.
