Funding Justification Guide

This guide provides information to support funding justification for the Permobil M Corpus VS power wheelchair base (K0861). It outlines key features and benefits that address the mobility needs of individuals with significant functional limitations.

Funding Justification Criteria for Permobil M Corpus VS (K0861)

Permobil M Corpus VS, Multiple Power Wheelchair Base

• Client's mobility limitation is due to a neurological condition, myopathy, or congenital skeletal deformity impairing their ability to perform one (1) or more mobility-related activities of daily living (MRADLs).
• Mobility limitation cannot be resolved with lesser mobility devices (e.g., cane, walker, manual wheelchair [WC], or power-operated vehicle [POV]).
• The power wheelchair (PWC) will improve the client's ability to perform their MRADLs.
• Client meets coverage criteria for power tilt and recline, or client uses a ventilator on their wheelchair, therefore requiring expandable electronics.
• Client has had a specialty evaluation performed by a licensed/certified medical professional like a physical therapist/occupational therapist (PT/OT).
• PWC is provided by a supplier employing an assistive technology professional (ATP).

Key Features and Benefits

E1007 | Power Tilt (ActiveReach™) and Recline

• Decreases the effects of shearing and increases weight distribution over the largest surface area possible.
• Client needs tilt for weight shift to control spasticity and posture, but needs recline to empty bladder or transfer flat.
• Power tilt/recline is needed for pain relief.
• Client has severe lower extremity (LE) edema, and tilt/recline combined with elevating legrests is the only way to get their lower extremities over the heart.
• Offers maximum pressure redistribution and postural support to reduce the risk of skin breakdown.
• Offers functional positions for eating, self-care, reaching, and repositioning.
• Provides appropriate positioning for bowel/bladder management (catheterization, urinal, and/or diapering).
• Recline, when combined with power tilt, minimizes shearing, promoting skin integrity when returning to a seated position.
• Provides positioning for blood pressure management (orthostatic hypotension).
• Provides positioning to control autonomic dysreflexia events.
• Allows multiple changes in position for improved rest breaks and helps eliminate the need for transfers in/out of the chair during the day.
• Promotes improved sitting tolerance and independent repositioning for pain management.
• Reduces respiratory distress by allowing various supported trunk positions.
• Facilitates exercise in the wheelchair by allowing multiple positions for therapeutic interventions.
• Provides more options for transfers, when needed, with one or two assistants, or independently, which is important for visits to the doctor, dentist, or other healthcare providers.

E1012 | Power Center Mount Elevating Legrests

• 90-degree knee position allows greater accessibility, a smaller turning radius, and greater stability (compact positioning).
• Flip-up footrest allows for independent or least assisted transfers.

E2300 | Power Adjustable Seat Height (ActiveHeight™)

• Positions client for easier transfers in a downhill direction, requiring less upper extremity strain.
• Compensates for lower extremity weakness, assisting with transfers and prolonging independence.
• Facilitates face-to-face conversations, improving social appropriateness and participation in social activities.
• Interactions at elevated heights reduce prolonged cervical hyperextension, lowering the risk of upper extremity pain/dysfunction.
• Improves self-confidence through face-to-face communication, increasing chances of success.
• Vertical mobility raises societal expectations of wheelchair users, providing them with an equal chance for success.
• Improves ability to access sinks, cupboards, and counters for enhanced independence in MRADLs.
• Elevation provides improved visibility for safety in public settings.
• Minimizes the need for overhead reaching when loading the upper extremity, reducing the risk of repetitive strain injury.

E2301 | Power Standing System

• Allows independent weight-bearing multiple times a day, essential for reducing osteoporosis and the risk of joint contractures, and facilitating normal bone and joint development.
• Transfers pressure away from the scapulae, sacrum, coccyx, and ischial tuberosities, reducing the risk of skin breakdown.
• Assists with digestion, respiration, bowel/bladder management, and appropriate bowel/bladder emptying, reducing the risk of constipation and urinary tract infections.
• Improves psychosocial status and participation, allowing increased access and independence to perform normal MRADLs and instrumental activities of daily living.
• Provides improved compliance with standing programs by having the standing feature readily available for active, independent use while in the wheelchair.
• Increases reach for functional access, making the client more productive at home, school, and/or work, and reduces overhead reaching and risk of shoulder injury.
• Improves access to toilets, sinks, counters, cabinets, and closets, enhancing independence with MRADLs in the home, community, or workplace.
• When slowly coming to stand from a reclined position, stopping as needed, it reduces the risk of orthostatic hypotension, controls abnormal or primitive reflexes, and provides spasticity management.
• Reduces depression and other psychosocial issues, enhances interaction with others, and allows clients to connect face-to-face with peers.
• Allows the client to stand and drive, providing an effective means of pressure relief to reduce the risk of skin breakdown.
• Enables specific functions that the client is unable to achieve while seated but can achieve while standing.

E2311 | Multiple Seat Function Control Kit

• Allows client to operate tilt/recline system through the drive control independently.
• Allows seating system to be speed controlled to decrease spasticity and control upper extremities.
• Allows seating system to limit tilt/recline angles due to disorientation or poor trunk control.
• Allows tilt/recline to work in a specific order/direction based on the client's movements.
• Addresses situations where a client is unable to operate power seat functions safely and consistently through separate switches due to decreased upper extremity strength/fine motor control, abnormal tone, decreased range of motion, or the need for alternative drive controls (head array, sip & puff, chin control, etc.).
• Reduces fatigue associated with switching between drive control and seat function controls.
• Client requires individually set Memory Seat Function positions, programmed through the joystick, for safe and consistent access to frequently used positions for MRADLs and transfers.
• Client requires Independent Repositioning Mode (IRM) for safe and consistent optimal pressure relief and posterior weight shifts to mitigate skin breakdown risk.

E2313 | Harness for Expandable Electronics

• Required for expandable electronics and provides necessary connectors for operation.

E1028 | Swingaway/Removable Hardware for Joystick

• Allows joystick to swing away for transfers without interference.

E1028 | Swingaway/Removable Hardware for Positioning Accessories

• Allows positioning accessories to swing away, giving the client increased independence in performing MRADLs.
• Permits safe transfers to bed and commodes.

E2363 | Group 24 Batteries

• Two (2) batteries are required for the operation of the power wheelchair.

E2377 | Expandable Controller

• The expandable controller is the Power Platform located in the chair's base, enabling the input device to communicate with actuators, drive motors, and gearboxes. A harness is required with the expandable controller.
• Provides access to multiple programmed drive modes for safe mobility.
• Offers full programmability for independent driving: latched, RIM mode, axis selection, power level adjustment for safety.
• Allows use of an attendant control, emergency stop switch, environmental control unit (ECU), or separate display for visual or cognitive impairments.
• Allows the client to operate three (3) or more power seat options on the wheelchair base; a non-expandable controller does not support these features.
• Allows the system to accommodate an alternate drive control now or in the future as impairments progress, which may be required for independent, safe operation due to decreased strength and motor control.

E2620 | Corpus Ergo Back

• Addresses significant postural asymmetries due to diagnoses such as: Monoplegia, Hemiplegia, Paraplegia, Quadriplegia, Muscular Dystrophy, Cerebral Palsy, Multiple Sclerosis, Amyotrophic Lateral Sclerosis, Alzheimer's, Parkinson's, and Spina Bifida.

E2622 | Corpus Ergo Air Cushion

• Client has a current pressure injury, or a history of a pressure injury, on the area of contact with the seat support surface.
• Client has absent or impaired sensation in the area of contact with the seat support surface.
• Client is unable to carry out a functional weight shift due to a qualifying diagnosis.

E0953 | Lateral Thigh/Knee Support

• Thigh supports are multi-position, angle-adjustable pads with removable hardware.
• Client requires these pads to properly align the legs due to abnormal tone and to provide appropriate lower extremity positioning when in the wheelchair.

E0955 | Headrest

• Client needs to be able to rest their head in the tilt/recline position.
• Client cannot support their own head due to weakness or tone.
• Needed for safety while being transported in their wheelchair.
• Needed to control primitive reflexes which, if not inhibited, will cause postural deformity.

E0956 | Lateral Trunk Support

• Client needs lateral stability for lack of trunk control due to loss of muscle function, abnormal tone, or reflexes.
• Needed to correct or accommodate scoliosis that will worsen and can cause respiratory, skin, and digestive problems.
• Needed to provide proximal control so the client may function distally using their upper extremities for function (e.g., eating, driving a power chair, writing).
