CMS Payment | IRF PPS | CMS-1845-F
The answer first: CMS finalized a 2.3% payment update for Inpatient Rehabilitation Facilities in FY2027. The FY 2027 IRF PPS Final Rule (CMS-1845-F) was issued July 30, 2026 and published on the Federal Register website August 3, 2026. The math is simple: a 3.2% market basket increase, reduced by a 0.9 percentage point productivity adjustment. The rule also carries the annual refresh of CMG relative weights, the outlier threshold, and the wage index, plus a revised IRF QRP data submission deadline. Rehab billing teams should reload CMG weights and re-check outlier reconciliation before October 1, 2026. The quieter headline sits in the RFI feedback summary, which signals broader IRF payment reform ahead. FY2028 is the cycle to watch.
The FY2027 Rate Dial
Net IRF PPS payment update, effective FY2027
What actually changed, in one read
The 2.3% headline is modest, and CMS built it the way it always does: the market basket measures input cost inflation for IRFs, and the statutory productivity adjustment claws part of it back. For FY2027 that is 3.2% less 0.9 percentage points. There is no drama in the arithmetic. The operational work lives in everything that turns over alongside the rate on October 1, 2026.
CMG relative weights
The case-mix group weights that drive every IRF claim's base payment are updated for FY2027. Stale weight tables in your billing or contract-modeling systems will misprice expected reimbursement from the first October discharge.
Outlier threshold
The high-cost outlier threshold resets annually. Any reconciliation logic, expected-payment calculator, or variance report keyed to the FY2026 threshold needs the new value before you work October remits.
Wage index
Geographic wage adjustments are updated for FY2027. Multi-site rehab operators should re-run per-facility rate expectations, since wage index movement can matter more than the headline update in some markets.
IRF QRP submission
The final rule revises the IRF Quality Reporting Program data submission deadline. Missing QRP requirements carries a payment penalty, so pull the revised deadline from the rule text and reset your compliance calendar now.
The dates that matter
The RFI feedback is the real signal
Buried behind the rate tables, the final rule summarizes the feedback CMS received on its IRF payment-reform request for information. CMS does not collect and publish RFI feedback for fun. When an RFI summary lands in a final rule, it usually means the agency is building the analytical record for future rulemaking. Read plainly, CMS is telegraphing that the current IRF payment structure is under active review and that more consequential proposals are likely in a coming cycle.
Our read: treat FY2027 as a maintenance year and use it to get your IRF payment data clean, because the FY2028 proposed rule is where structural change is most likely to surface. Facilities that can model payment scenarios quickly will be the ones able to comment meaningfully, and comment windows are short.
Operator checklist: before October 1, 2026
- Reload FY2027 CMG relative weights into your billing system, expected-payment calculators, and any payer contract models that reference Medicare IRF rates.
- Update the outlier threshold and re-check your outlier reconciliation workflow end to end, from cost-to-charge inputs through the variance reports your AR team works.
- Re-run wage index impacts per facility and refresh budgeted net revenue for FY2027, especially for multi-site operators where geographic movement cuts both ways.
- Reset the IRF QRP calendar to the revised data submission deadline in CMS-1845-F and confirm ownership of each submission task.
- Verify October claims against the new rates. Sample early FY2027 remits, compare actual to expected at the claim level, and catch mispriced payments in the first weeks rather than at quarter close.
- Start an FY2028 watch file. Log the RFI themes from the final rule and assign someone to track the FY2028 proposed rule the day it drops.
A 2.3% year rewards clean execution
When the rate update is modest, the money is made or lost in the details: accurate CMG weights, tight outlier reconciliation, and claims that price right the first time. ASP-RCM Solutions helps rehab providers reload the FY2027 tables, verify expected versus actual payment at the claim level, and build the reporting muscle to respond when the FY2028 reform cycle arrives.
