Modifier KU

The KU modifier is used to receive the unadjusted fee schedule amount and was implemented for a variety of wheelchair accessories and seat back cushions used with complex rehabilitative manual wheelchairs and certain manual wheelchairs. The use of the KU modifier started for claims submitted on July 6, 2020 and was extended on July 6, 2021 per MM12345. The impacted accessories and wheelchair codes include K0005, E1161, E1231-E1238 and K0008. Previously paid claims with dates of service on or after January 1, 2020 can be reopened to add the KU modifier.

On October 1, 2021, with an implementation date of October 4, 2021, MLN Matters Article MM12453 was published. This article provides direction to continue including the KU modifier when billing the manual and power wheelchair accessories and seat and back cushion codes given with the wheelchairs discussed above. A list of the wheelchair accessory and seat and back cushion codes given with Group 3 power wheelchairs (HCPCS codes K0848-K0864) is available in Attachment A of CR 12453.
