410-122-0320 Manual Wheelchair Base (1) Indications and limitations of coverage and medical appropriateness: (a) The Division may cover a manual wheelchair when conditions of coverage in OAR 410-122-0080 and all of the following criteria are met: (A) The client has a mobility limitation that significantly impairs their ability to participate in one or more mobility-related activities of daily living (MRADLs) in or out of the home. MRADLs include but are not limited to tasks such as eating, toileting, grooming, dressing, and bathing. A mobility limitation is one that: (i) Prevents the client from accomplishing an MRADL entirely; (ii) Places the client at reasonably determined heightened risk of morbidity or mortality secondary to attempts to perform an MRADL; or (iii) Prevents the client from completing an MRADL within a reasonable time frame. (B) An appropriately fitted cane or walker cannot sufficiently resolve the client’s mobility limitation; (C) If the client shall be using the wheelchair in the home, the home provides adequate maneuvering space, maneuvering surfaces, and access between rooms for use of the manual wheelchair that is being requested; (D) Use of a manual wheelchair shall significantly improve the client’s ability to participate in their MRADLs. For clients with severe cognitive or physical impairments, participation in MRADLs may require the assistance of a caregiver; (E) The client is willing to use the requested manual wheelchair on a regular basis; (F) The client has either: (i) Sufficient upper extremity function and other physical and mental capabilities needed to safely self-propel the requested manual wheelchair during a typical day. Proper assessment of upper extremity function shall consider limitations of strength, endurance, range of motion, coordination, presence of pain, and deformity or absence of one or both upper extremities; or (ii) A caregiver who is available, willing, and able to provide assistance with the wheelchair. (b) The Division may authorize a manual wheelchair for any of the following situations, only when conditions of coverage as specified in section (1)(a) of this rule are met: (A) When the wheelchair can be reasonably expected to improve the client’s ability to complete MRADLs by compensating for other limitations in addition to mobility deficits, and the client is compliant with treatment: (i) Besides MRADLs deficits, when other limitations exist, and these limitations can be ameliorated or compensated sufficiently such that the additional provision of a manual wheelchair may be reasonably expected to significantly improve the client’s ability to perform or obtain assistance to participate in MRADLs, a manual wheelchair may be considered for coverage; (ii) If the amelioration or compensation requires the client's compliance with treatment, for example medications or therapy, substantive non-compliance, whether willing or involuntary, can be grounds for denial of manual wheelchair coverage if it results in the client continuing to have a significant limitation. It may be determined that partial compliance results in adequate amelioration or compensation for the appropriate use of a manual wheelchair. (B) For a purchase request, when a client’s current wheelchair is no longer medically appropriate, or repair and modifications to the wheelchair exceed replacement cost; (C) When a covered, client-owned wheelchair is in need of repair, the Division may pay for one (1) month’s rental of a wheelchair in accordance with OAR 410-122-0184 Repairs, Maintenance, Replacement, Delivery and Dispensing. (c) The Division may not reimburse for another wheelchair if the client has a medically appropriate wheelchair, regardless of payer; (d) If the client shall be using the wheelchair in the home, the home must be able to accommodate and allow for the effective use of the requested wheelchair. The Division does not reimburse for adapting living quarters; (e) The Division may not cover services or upgrades that primarily allow performance of leisure or recreational activities. Such services include but are not limited to backup wheelchairs, backpacks, accessory bags, awnings, additional positioning equipment if wheelchair meets the same need, custom colors, and wheelchair gloves; (f) Reimbursement for wheelchair codes includes all labor charges involved in the assembly of the wheelchair, as well as support services such as delivery, set-up, pick-up and delivery for repairs/modifications, education, ongoing assistance with the use of the wheelchair; and if provided, emergency services; (g) The Division may cover an adult tilt-in-space wheelchair (E1161) when a client meets all of the following conditions (A-I): (A) A standard base with a reclining back option will not meet the client’s needs; (B) Requires assistance with transfers; (C) The client’s plan of care addresses the need to change position at frequent intervals, and the client is not left in the tilt position most of the time; and (D) Has one of the following: (i) High risk of skin breakdown; (ii) Poor postural control, especially of the head and trunk; (iii) Hyper/hypotonia; (iv) Need for frequent changes in position and has poor upright sitting. (E) The client must have a specialty evaluation, conducted within six (6) months prior to the start of services, that was performed by a licensed/certified medical professional, such as a PT or OT, or treating practitioner who has specific training and experience in rehabilitation wheelchair evaluations and documents the medical necessity for the wheelchair and its special features, including a description of the client's mobility needs within the home and community. The PT, OT, or treating practitioner billing or rendering services must not have a financial relationship with the DMEPOS provider; (F) Tilt-n-space wheelchairs must be supplied by a DMEPOS provider that employs a Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) certified Assistive Technology Professional (ATP) who specializes in wheelchairs and who has direct, in-person involvement in the wheelchair selection for the client; (G) The ATP must be employed by the provider in a full-time, part-time, or contracted capacity as is acceptable by state law.
