Research from CMS reference data
Reviewed by QuickIntell RCM Editorial Team · Last reviewed
Data effectiveEach report is computed directly from published CMS files using the method documented on the reference methodology page, so every figure can be reproduced. New reports follow each CMS release: NCCI and ASP quarterly in January, April, July and October, MS-DRG and ICD-10 on October 1, and the Medicare Coverage Database weekly.
- FY2027 MS-DRG weight changes: winners and losers
Every MS-DRG relative weight compared FY2026 to FY2027 from IPPS Table 5, with the 25 largest moves each way and the new DRGs.
What these reports are for
Revenue-cycle teams rarely have time to diff a CMS release against the previous one, yet the differences are where money moves: a relative weight that fell near the ten percent cap, a drug whose payment limit jumped between quarters, a procedure pair that CMS started bundling, or a laboratory diagnosis list that lost codes in January. Each report here takes one published CMS file, compares it with the prior release using a documented method, and lists the entities that changed most, with a link to the full reference page for each one.
Figures are reproducible: the source file, version, effective date and SHA-256 hash appear on every report, the computation is described on the methodology page, and the same projection that renders the reference pages produces the tables, so a number on a report always matches the number on the entity page. The reports carry no model-written interpretation; the text explains the method and the practical use of the figures.
Publication schedule
The NCCI PTP, MUE and add-on edits, the ASP drug payment limits, the HCPCS file and OPPS Addendum B all change on the first day of January, April, July and October; reports on those datasets follow within five business days of each release. MS-DRG weights, ICD-10 codes and the IPPS tables change on October 1 with the final rule published in August, so the DRG report is annual with a mid-year note when CMS issues a corrected or v44.1 release. The Medicare Coverage Database updates every Thursday, and coverage-change digests will summarise new, revised and retired policies by contractor.
Reuse
Tables and figures may be quoted or republished with attribution to QuickIntell and a link to the report; the underlying CMS data is public domain. Report an error or request a cut of the data through the contact page and the correction will be recorded on the report with the date. Downloadable CSV extracts accompany each report where the source licence allows it, which excludes any table that would reproduce CPT descriptors; those tables carry code numbers only, in line with the licensing rules on the methodology page, and the HCPCS Level II, ICD-10 and MS-DRG tables are complete.
