# HCPCS/CPT -> HCRIS cost-center crosswalk (the precision layer)

`medicare_silver.hcpcs_cost_center_crosswalk` · Medicare Advantage, Part D, Medicaid · status live · 28,328 rows

The map that makes cost-based pricing accurate: each billing code -> the cost center where a hospital accumulates that service's cost (CT, MRI, Lab, OR, Clinic, ...). Derived from a 1.8-billion-row EMPIRICAL bridge (the modal UB-04 revenue code hospitals actually billed each code under, from our MRF) mapped through the authoritative CMS revenue-code -> cost-center spine, then adversarially validated by a sub-agent fleet (2,805 high-value codes). Join hcpcs -> cost_center_line, then use hospital_cost_report_dept for that center's CCR.

**Grain.** One row per HCPCS/CPT code. 28,328 codes -> their HCRIS 2552-10 Worksheet C cost center, so a code can be priced on the RIGHT department cost-to-charge ratio.
