What it does

One workbench. Six surfaces.

Filter, rank, queue, slice, brief, and feed --- all from one static deploy.

Ranked

Changes

Every CMS revision sorted by impact heuristics, with deep-linkable filters so you can share a high-impact coding view to a teammate.

Triaged

Operator queues

Coding, criteria, effective dates, national policy, and retirements, pre-grouped into review lanes that map to real workflow questions.

Sliced

Per contractor

Each MAC footprint gets its own JSON, RSS, CSV, and Monday brief. Drop the URLs into a script, scheduler, or feed reader.

Static feeds

Drop a URL. Get current data.

No API key. No rate limit. No login. Just files that update each weekday.

RSS

Subscribe in Feedbin, Feedly, NetNewsWire, or pipe into Slack/Teams.

Flat JSON

Array of records. Drop into any script, fetch, jq, or pandas.

High-impact only

Smaller payload, scoped to changes most likely to break workflow.

Code node

const r = await this.helpers.httpRequest({

});
return r.entries.filter(e => e.impact === 'high');

Why it exists

Public source over black-box summary.

CMS publishes the data. Most paid coverage tools wrap it, mark it up, and lock it behind a login. We thought a free changelog with source citations and operator review lanes was a more useful default for billing teams, RCM analysts, and practice operators.

Every entry links to the official CMS document. The build runs every weekday and publishes static files. If we ever go away, the artifacts keep working.

Use it

Free for everyone. Forever.
