Current: CMS last published this feed on 2026-08-17. Coverage runs through 2026-08-31. Next CMS release expected ~Sep 2026.

Time-partitioned feed: each file version covers one reporting period, so history is additive. Query the full table for all periods; filter on the reporting period columns for a single period. Do not filter to the latest file only (that would return just the 2026 reporting period).
