What counts as news here?

An item counts as news here only when it comes from an official source: a CMS rule, a Federal Register notice or correction, or an edit release such as the NCCI procedure-to-procedure edits. We do not report commentary, vendor summaries or rumours.

The items so far cover Medicare payment rules, the No Surprises Act, prior authorization, price transparency and NCCI edits. For example, the FY 2027 IPPS final rule and the federal IDR operations final rule each have their own page.

The standing rule pages stay in the rules library, and the No Surprises Act detail is in the IDR operations rule page. Posts here link to them so one fact is kept in one place.

How do you read a rule's dates?

A rule has more than one date, and each one answers a different question. The publication date says when the rule appeared in the Federal Register. The effective date says when it applies to your claims.

DateWhat it tells youExample on this site
Federal Register publicationWhen CMS or another agency published the document.The FY 2027 IPPS final rule was published August 4, 2026.
Effective dateWhen the rule applies to claims.The same rule applies to discharges on or after October 1, 2026.
Comment deadlineThe last day to send comments on a proposed rule. A proposal can change in the final rule.Comments on the CY 2027 physician fee schedule proposal were due September 14, 2026.
CorrectionA notice that fixes an earlier rule and may apply back to its start.The CY 2026 OPPS and ASC correction applies back to January 1, 2026.

Edit releases follow the same idea. NCCI PTP edits version 32.3 took effect October 1, 2026. Check the effective date before you change a claim edit or a payment worklist.

For the background on a topic, the guides and the blog explain how the rule changes daily work. Our editorial policy says how each page is sourced and checked.

01Where can I find medical billing news?

This page lists billing news from official sources: CMS final and proposed rules, Federal Register corrections and notices, and edit releases such as NCCI. Each item gives its publication date, its effective date and the billing steps that follow. Browse the list newest first, or open the item for the topic you bill.

02What counts as news on this page?

Only items that come from an official source count: a CMS or Federal Register rule, a correction, a notice or an edit release. We do not publish commentary, rumours or vendor summaries as news. Each item names its source in the sentence and lists it at the bottom of the page.

03What is the difference between a proposed rule and a final rule?

A proposed rule is a draft CMS publishes for public comment, and its values can change. A final rule is the version that applies, from its effective date. Each news item says which one it covers and gives the comment deadline for a proposal, so you know whether the numbers are settled.

04Why is the effective date different from the publication date?

The publication date is when the Federal Register printed the rule. The effective date is when it applies to claims, and it is often weeks or months later. The FY 2027 IPPS final rule was published August 4, 2026 and applies to discharges on or after October 1, 2026.

05How soon do you post a CMS rule change?

Each item shows the date CMS or the Federal Register published the document, so you can see how recent it is. If a source changes later, the item is re-checked and its last-reviewed date is updated.

06Where do the No Surprises Act updates go?

No Surprises Act rule changes are listed here as news, such as the federal IDR operations final rule and its correction. The standing explanation of how the process works is on the No Surprises Act pages, which the news items link to.
