410-122-0325 Power Wheelchair Base (1) Indications and limitations of coverage and medical appropriateness: (a) The Division may cover a power wheelchair (PWC) when conditions of coverage in OAR 410-122-0080 and all 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 toileting, feeding, dressing, grooming, and bathing. A mobility limitation is one that: (i) Prevents the client from accomplishing an MRADL entirely; or (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) The client does not have sufficient upper extremity function to self-propel an optimally-configured manual wheelchair to perform MRADLs during a typical day: (i) Assessment of upper extremity function shall consider limitations of strength, endurance, range of motion or coordination, presence of pain, and deformity or absence of one or both upper extremities; (ii) An optimally-configured manual wheelchair is one with an appropriate wheelbase, device weight, seating options, and other appropriate non-powered accessories. (D) If the client shall be using the PWC in the home, the home provides adequate maneuvering space, maneuvering surfaces, and access between rooms for the operation of the PWC that is being requested; (E) Use of a PWC shall significantly improve the client’s ability to participate in MRADLs. For clients with severe cognitive and physical impairments, participation in MRADLs may require the assistance of a caregiver; (F) The presence of a caregiver does not preclude coverage of a PWC if the client is willing and able to safely operate the PWC; (G) The client is willing to use the requested PWC on a regular basis; (H) There is objective evidence that demonstrates that the client cannot use a power-operated vehicle (POV); (I) The client has sufficient mental and physical capabilities to safely operate the PWC; (J) If the client is unable to safely operate the PWC and has a caregiver, the Division may cover the PWC if the caregiver is unable to adequately propel an optimally-configured manual wheelchair and is available, willing, and able to safely operate the PWC being requested. The caregiver’s need to use a PWC to assist the client with their MRADLs shall be considered in determining coverage; (K) The client’s weight is less than or equal to the weight capacity of the PWC requested. (b) Only when conditions of coverage as specified in section (1) (a) of this rule are met may the Division authorize a PWC for any of the following situations: (A) When the PWC 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 PWC will be reasonably expected to significantly improve the client’s ability to perform or obtain assistance to participate in MRADLs, a PWC 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 PWC 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 PWC. (B) When a client’s current wheelchair is no longer medically appropriate, or repair and modifications to the wheelchair exceed replacement costs; (C) When a covered client-owned wheelchair is in need of repair, the Division may pay for one month’s rental of a wheelchair. (c) For a PWC to be covered, the treating practitioner must conduct a face-to-face examination of the client within six (6) months prior to writing the order and that visit with the treating practitioner starts the six (6) month timeline; (A) The treating practitioner’s face-to-face examination of the client can be performed during a hospital or nursing facility stay; however, the visit must be conducted within six (6) months prior to writing the order; (B) The practitioner may refer the client to a licensed/certified medical professional, such as a physical therapist (PT) or occupational therapist (OT), to provide the assessment for the wheelchair. This individual must not be an employee of the DMEPOS provider or have any direct or indirect financial relationship, agreement, or contract with the DMEPOS provider. When the DMEPOS provider is owned by a hospital, a PT/OT working in the inpatient or outpatient hospital setting may perform part of the face-to-face examination: (i) If the client was referred to the PT/OT before being seen by the practitioner, then once the practitioner has received and reviewed the written report of this examination, the practitioner must see the client and perform any additional examination that is needed. The practitioner’s report of the visit shall state concurrence or any disagreement with the PT/OT examination and must occur within the six (6) month timeframe; (ii) If the practitioner examined the client before referring the client to a PT/OT, then again in person after receiving the report of the PT/OT examination, it is also acceptable for the practitioner to review the written report of the PT/OT examination, to sign and date that report, and to state concurrence or any disagreement with that examination. In this situation, the practitioner must send a copy of the note from his initial visit to evaluate the client plus the annotated, signed, and dated copy of the PT/OT examination to the DMEPOS provider; (iii) If the PWC is a replacement of a similar item that was previously covered by the Division or when only PWC accessories are being ordered and all other coverage criteria in this rule are met, a face-to-face examination is not required. (d) The Division does not reimburse for another chair if a client has a medically appropriate wheelchair, regardless of payer; (e) If the client will be using the PWC in the home, the home must be able to accommodate and allow for the effective use of the requested PWC. The Division does not reimburse for adapting the living quarters; (f) The equipment 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. The ATP, if part-time or contracted, must be under the direct control of the provider; (h) Documentation must be complete and detailed enough so a third party shall be able to understand the nature of the provider’s ATP involvement, if any, in the licensed/certified medical professional (LCMP) specialty evaluation; (i) The ATP may not conduct the provider evaluation at the time of delivery of the power mobility device to the client’s residence; (j) Reimbursement for wheelchair codes includes all labor charges involved in the assembly of the wheelchair and all covered additions or modifications. Reimbursement also includes support services such as delivery, set-up, pick-up and delivery for repairs/modifications, education, ongoing assistance with use of the wheelchair, and if provided, also includes support services such as emergency services; (k) The delivery of the PWC must be within 120 days following approval of the PA request by the Division; (l) A PWC may not be ordered by a podiatrist; (2) The Division does not consider the following services medically necessary or medically appropriate: (a) A PWC for clients who are able to independently self-propel an optimally configured manual wheelchair; (b) A PWC with a captain’s chair for a client who needs a separate wheelchair seat and/or back cushion; (c) Items or upgrades that primarily allow performance of leisure or recreational activities including but not limited to backup wheelchairs, backpacks, accessory bags, awnings, additional positioning equipment if wheelchair meets the same need, custom colors, and wheelchair gloves; (3) Coding Guidelines: (a) Specific types of PWCs: (A) A Group 1 PWC (K0813-K0816) or a Group 2 PWC (K0820-K0829) may be covered when all of the coverage criteria for a PWC are met and the wheelchair is appropriate for the client’s weight and physical dimensions; (B) A Group 2 PWC with a seat elevation system (K0830-K0831) may be covered when all of the coverage criteria for a PWC are met, and criteria for a power seat elevation system are met in accordance with OAR 410-122-0340; (i) When billing a heavy duty or very heavy-duty power wheelchair described by HCPCS codes K0824, K0825, K0826, K0827, K0828, and K0829 that could include a seat elevation system, that system, if included, shall be billed separately under HCPCS code K0108 by using HCPCS codes K0824 - K0829 plus K0108; (ii) K0108 may also be applied to Group 2 noncomplex heavy-duty bases (K0824, K0825, K0826, K0827, K0828, and K0829) and Group 5 power driven wheelchair bases. For example, a K0825 wheelchair with an accessory seat elevation system shall be billed using K0108.
