# CMS POS Long-Term Care Hospital Roster

`medicare_silver.dim_ltch` · Provider identity · status live · 655 rows

CMS Provider of Services File, the LEGACY "Hospital_and_other" distribution, FILTERED to long-term care hospitals (prvdr_ctgry_sbtyp_cd = "02"). LTCHs are hospital SUBTYPES, not in the iQIES file — the hospital-file sibling of the post-acute rosters. Roster spine — CCN, facility name, city/state/ZIP, composed 5-digit county FIPS, active flag, provider subtype/category, ownership/control code.

**Grain.** One row per Medicare-certified long-term care hospital (by CCN) per quarterly POS snapshot.
