WHILL Model A

This code is considered as all-inclusive for this product. None of the existing HCPCS codes for wheelchair bases, options, accessories, seating, etc. are appropriate for use with this product. Claims for this item using existing wheelchair related codes will be denied as incorrect coding.

The WHILL Model M received a 510(k) FDA clearance for marketing as a Class II Powered Wheelchair on February 12, 2016. A HCPCS code request for this product has not been submitted to the Pricing, Data Analysis and Coding (PDAC) Contractor. For Medicare billing purposes, claims for this device must be submitted using HCPCS code:

  • K0899 - POWER MOBILITY DEVICE, NOT CODED BY DME PDAC OR DOES NOT MEET CRITERIA

This code is considered as all-inclusive for this product. None of the existing HCPCS codes for wheelchair bases, options, accessories, seating, etc. are appropriate for use with this product. Claims for this item using existing wheelchair related codes will be denied as incorrect coding.
