Manual WCs (rigid or folding, standard or specialized) are devices used to assist adults and children in the mobility-related activities of daily living (MRADLs),

Power mobility devices (PMDs) - Power wheelchairs (PWCs) and power-operated vehicles (POVs, scooters) are collectively referred to as PMDs. They are used to assist individuals in their MRADLs in the home.

Mobility-assistive equipment (MAE) are necessary devices used to assist adults and children in the MRADLs. MAE includes, but is not limited to: manual WCs, rolling chairs, PWCs, and POVs.

Options/Accessories - Options and accessories for WCs and mobility devices are any adaptive equipment that is necessary if the individual has a WC, PMD or MAE and the option/accessory for the device.

Standard WCs may be considered medically necessary when ALL of the following criteria are met:

• The individual would otherwise be confined to a bed or chair. The individual is considered confined to a bed or chair if he or she is unable to ambulate from, for example, bed to bathroom, bedroom to kitchen, or around the home; and
• The individual has a disease process or injury for which weight-bearing and/or ambulation is contraindicated; and
• The individual has a disease process or injury that precludes use of the lower extremities (e.g., a neuromuscular disease).

Specialized manual WCs, strollers and/or WC enhancements may be considered medically necessary when the individual meets coverage criteria for a standard WC and the additional accompanying criteria for the specified enhancement are also met:

• A transport chair as an alternative to a standard manual WC;

• A high-strength, lightweight WC when ONE of the following additional criteria is met:
  • The individual can self-propel a high-strength lightweight WC while engaging in frequently performed activities that cannot otherwise be completed in a standard or lightweight WC; or   
  • The individual requires a seat width, depth or height that cannot be accommodated in a standard, lightweight or hemi-WC and spends at least two (2) hours per day in the WC.
  • A high-strength lightweight wheelchair is rarely reasonable and necessary if the expected duration of need is less than three months (e.g., post-operative recovery).

• A heavy-duty WC if the individual weighs greater than 250 pounds or has severe spasticity; or
• An extra-heavy-duty WC if the individual weighs greater than 300 pounds; or
• A manual WC with tilt in space is covered if the beneficiary meets the general coverage criteria for a manual WC above; or   
• A custom WC base is covered as medically necessary only if the feature needed is not available as an option to an existing manufactured base; or
• A pediatric size WC if a seat width and/or depth of 14 inches or less is recommended; or

·        A customized pediatric stroller for a child who is non-ambulatory when EITHER of the following conditions apply:  

• The child requires more support than is available in a standard pediatric WC; or
• The child is too small to safely use a standard pediatric WC; or

• A semi/fully reclining WC when ANY of the following are present:
  • Quadriplegia; or
  • Fixed hip angle; or
