Clinical UM Guideline

This document addresses criteria related to accessories and options for manual or powered wheelchairs. Wheeled mobility devices include, but are not limited to manual wheelchairs (for example, standard, heavy duty, lightweight, ultra lightweight), powered wheelchairs, motorized wheelchairs or power operated vehicles (scooters). Wheelchair accessories and options are available for those individuals with specific medical needs related to mobility.

Note: Robotic wheelchair accessories are not addressed in this document, please refer to DME.00044 Robotic Arm Assistive Devices for additional consideration.

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

      1. Individual uses one or both feet to self-propel wheelchair due to weakness or dysfunction of at least one upper extremity;
   5. One-arm drive (allows a manual wheelchair user to self-propel in a forward motion with only one upper extremity; those who use this option generally use one or more feet at a hemi-height seat level to self-propel):
      1. Individual has weakness or dysfunction of at least one upper extremity;
   6. Swing-away hardware (used to move the component out of the way to enable the individual to transfer to a chair or bed):
      1. Individual has difficulty with transfers;
   7. Elevating leg rests:

   8. Safety belt, pelvic strap or chest strap:
      1. The individual has upper body muscle weakness, upper body instability, or muscle spasticity, which requires use of this item for proper positioning;
   9. Semi or fully reclining back option:

      2. Cannot reposition self; and
      3. Has a medical need to rest in a recumbent position two or more times during the day; and
      4. Transfer between wheelchair and bed is difficult because of quadriplegia, fixed hip angle, trunk or lower extremity casts/braces, or excess extensor tone of the trunk muscles;

The Centers for Medicare and Medicaid Services (CMS) Mobility Assistive Equipment National Coverage Decision (NCD), which considers the clinical indications for the appropriate types of mobility assistive devices as well as options/accessories for these devices were utilized in the development of this document.

Mobility impairments include a broad range of disabilities that affect a person's independent movement and cause limited mobility. In 2022, the National Center for Medical Rehabilitation Research (NCMRR) Program, estimates 31 million people have mobility impairments, which may take the form of paralysis, muscle weakness, nerve damage, stiffness of the joints, or balance/coordination deficits. According to the Centers for Disease Control and Prevention (2020) there are three dimensions of disability: impairment, activity limitations, and participation restrictions. In the Americans with Disabilities Act the census estimated that over 4% of the United States population has moderate to severe disability requiring an individual to use a wheelchair to assist with mobility in nearly 4 million Americans, aged 15 years and older are required to use a wheelchair (National Census Bureau, 2012).

Cherubini and colleague (2011) conducted an observational study of 150 wheelchair users (n=80 men, n=70 women) with an average age of 46.7 ± 17.3 years, to analyze the congruence of the prescribed wheelchair and the individual’s mobility needs. The subjects had varied disabilities, 24% spinal cord injury, multiple sclerosis 18%, cerebral infantile paralysis 18% and skull trauma 10%. The authors found that 68% of the prescribed wheelchairs were not suitable in reference to the wheelchair and accessories. After finding a correlation between the prescription sources and the suitability of the wheelchair for the individual, it was concluded that wheelchair prescriptions should be based on careful assessment of mobility needs and improved collaboration between physicians and technicians.

Selecting wheelchair options/accessories is individualized and must consider the user's impairment, level of function, surrounding environment, activity level, seating and positioning needs.

In some cases, individuals may have postural asymmetry that does not allow them to sit in an upright position without appropriate accessories to provide positional support. Such conditions may include but are not limited to above knee leg amputation, Alzheimer’s disease, amyotrophic lateral sclerosis, athetoid cerebral palsy, cerebral palsy, anterior horn cell diseases, childhood cerebral degeneration, hemiplegia due to stroke, idiopathic torsion dystonias, monoplegia of the lower limb, multiple sclerosis, muscular dystrophy, osteogenesis imperfecta, paraplegia, Parkinson's disease, post-polio paralysis, quadriplegia, spina bifida, spinocerebellar disease, transverse myelitis, and traumatic brain injury.

Similarly, some conditions may result in the inability to carry out a functional weight shift that helps prevent the development of pressure ulcers. Some conditions in which this may be the case include Alzheimer’s muscular dystrophy, childhood cerebral degeneration, hemiplegia, Huntington’s chorea, idiopathic torsion dystonia, quadriplegia, spinal bifida, and athetoid cerebral palsy.

Activities of daily living (ADLs): Self-care activities such as transfers, toileting, grooming and hygiene, dressing, bathing, and eating.

Functional mobility: The ability to consistently move safely and efficiently, with or without the aid of appropriate assistive devices (such as prosthetics, orthotics, canes, walkers, wheelchairs, etc.), at a reasonable rate of speed to complete an individual’s typical mobility-related activities of daily living; functional mobility can be altered by deficits in strength, endurance sufficient to complete tasks, coordination, balance, speed of execution, pain, sensation, proprioception, range of motion, safety, shortness of breath, and fatigue.
