L6642 HCPCS Level II code: Upper extremity addition, excursion amplifier, lever type

L6642 is the HCPCS code for “Upper extremity addition, excursion amplifier, lever type” in CMS’s HCPCS Level II October 2026 release.

CMS lists L6642’s Medicare coverage as “Carrier judgment” and its pricing as “DMEPOS fee schedule – Orthotics, prosthetics, prosthetic devices & vision services (price subject to floors and ceilings)”. Coverage and payment still depend on the patient, the setting, the documentation and the payer.
