How this category is built

HCPCS Level II codes are organized by their first letter, which is how the range hubs on this site group them, but one kind of item or service often spans several letters: wheelchairs sit in the E and K ranges, supplies in A, B, Q and T, and imaging in A, C, G, Q and R. This hub regroups the codes by the BETOS category CMS records for each code in the HCPCS file, splitting the large prosthetic and orthotic category by L-code range and keeping vision and hearing items apart, so each non-drug code belongs to exactly one category hub besides its range hub. The national Medicare amount comes from the 2026 physician fee schedule, DMEPOS, clinical laboratory, OPPS or ASC file that prices the code, as on its reference page.
