Use of the KF Modifier with Osteogenesis Stimulators

Joint DME MAC Publication

Effective for any dates of service billed, claims for devices coded E0747, E0748, and E0760 must include the KF modifier. Codes E0747, E0748, and E0760 billed without a KF modifier will be rejected as missing information.

On May 14, 2026, in an MLN Connects newsletterExternal Website, the Centers for Medicare and Medicaid Services (CMS) announced that the Food and Drug Administration (FDA) had reclassified osteogenesis stimulators from Class III to Class II devices. The impacted HCPCS codes are:

E0747 Osteogenesis Stimulator, Electrical, Non-Invasive, Other than Spinal Applications
E0748 Osteogenesis Stimulator, Electrical, Non-Invasive, Spinal Applications
E0760 Osteogenesis Stimulator, Low Intensity Ultrasound, Non-Invasive

The May 14, 2026 instructions from CMS instructed suppliers to discontinue use of the KF modifier for dates of service on or after May 18, 2026. After further consideration, CMS is not making any changes to the fee schedules for HCPCS codes E0747, E0748, and E0760 at this time; therefore, suppliers must continue to use the KF modifier.
