2026 GPCIs for Colorado

2026 geographic practice cost indices for Medicare locality 04112-01
ComponentGPCIvs national 1.000
Work (physician time and effort)1.012+1.2%
Practice expense (staff, rent, equipment, supplies)1.064+6.4%
Malpractice (professional liability insurance)0.781-21.9%
Geographic adjustment factor (weighted)1.025+2.5%

A fee schedule amount here is [(work RVU x 1.012) + (practice expense RVU x 1.064) + (malpractice RVU x 0.781)] x the conversion factor. The practice expense index weighs most on office services, whose non-facility practice expense RVU carries the practice's overhead, while the work index weighs most on surgery and other physician-intensive services. The work index is above the 1.0 floor, so the floor does not affect this locality.

Localities with a similar adjustment

Ranked by geographic adjustment factor, the localities on either side of Colorado are El Centro, CA (1.032) and Rest of Massachusetts, MA (1.023). Localities with the same GAF can still pay a given code differently when their work and practice expense indices are mixed in different proportions.

DMEPOS amounts in Colorado

Durable medical equipment, prosthetics, orthotics and supplies are not priced by locality. The October 2026 DMEPOS fee schedule (DME26-D) sets one non-rural and one rural amount per code for the whole state, and the rural amount applies only in the ZIP codes on the quarterly DMEPOS rural list. The table shows the Colorado amounts for common items next to the lowest and highest non-rural amount among the contiguous states; HCPCS Level II descriptors are CMS's.
