A collection of datasets giving important dates involved in the Hospital Readmissions Reduction Program (HRRP), including performance periods, payment periods, review and correction periods, claims snapshot dates, and cohort inclusion status for program years since 2019. The data is manually abstracted from QualityNet and was most recently updated on 11/21/2025.
All tables contain the ProgramYear, which is the HRRP program (or federal fiscal year) in question.
Tables with date ranges contain a StartDate and EndDate contain the beginning and end dates of the
respective interval. Other tables contain individual dates or indicators for cohort inclusion (see descriptions).

hrrp_performance_periods
Start and end dates for discharges evaluated for readmissions. Note some program years have multiple performance intervals and are represented on separate rows of this table.
hrrp_payment_periods
Start and end dates for when payment penalties are applied by CMS to hospital reimbursement.
hrrp_review_periods
Start and end dates for the review and correction period where hospitals could review discharge-level data and downstream calculations of penalty amounts.
hrrp_snapshot_dates
The as of date for when claims data were extracted by CMS for evaluation in the program. Note some discrepancies exist in CMS documentation for these dates (e.g., FY2026) when comparing anticipated versus actual snapshot date. The latter was used in this case.
hrrp_cohort_inclusion
Indicators of whether each cohort was included in the program for the given year. 1 = included, 0 = excluded.
