OASIS calendar-year transition period closes
December 31, 2026
CMS proposed a six-month stub data-collection period (July 1 – December 31, 2026) to shift OASIS annual payment update reporting onto a calendar year. That window is running now and would determine your 2028 annual payment update.

PDGM functional points recalibration (CY2027), if finalized
January 1, 2027
CMS proposed re-deriving the functional points and impairment-level thresholds for the eight PDGM OASIS items using CY2025 claims data — the same annual recalibration methodology, not a redesign. Treat the proposed figures as provisional until the final rule.

CY 2027 HH PPS final rule — expected
expected fall 2026 (historical HH PPS final rules publish Oct–Dec, effective the following Jan 1; CY2026's final rule published Dec 2, 2025)
CMS typically finalizes the HH PPS rule in the fall, effective the following January 1. Expect the CY2027 payment rate, OASIS deadline, and PDGM recalibration figures to be confirmed — and possibly revised — around then.

HH PDGM grouper v07.2.26 + ICD-10-CM FY2027 take effect
October 1, 2026
CMS posted the Oct 2026 HH PPS Grouper Software (HH PDGM v07.2.26) on August 20, 2026, with tables effective October 1, 2026 and no logic changes. It carries the FY2027 ICD-10-CM code set: 190 codes added, 30 deleted, and no existing code changes clinical group. The grouper picks its table by the claim from date, so periods starting October 1 or later use the new table.
