Data sources
Where CLV Intelligence gets its data
CLV Intelligence draws exclusively from official, publicly available government and regulatory sources — 9 source families across CMS, all 7 Medicare Administrative Contractors, the Federal Register, the OIG, and the FDA. Every alert links back to the originating document, so nothing rests on our interpretation alone.
CMS Medicare Coverage Database (LCDs & NCDs)
Visit source ↗Local and National Coverage Determinations — the coverage criteria and medical-necessity requirements that drive most Medicare coverage decisions and denials.
CMS Transmittals (Publication 100-04)
Visit source ↗Internet-Only Manual transmittals and Change Requests that operationalize Medicare policy for claims processing.
All 16 MAC jurisdictions — via the CMS Coverage Database
Visit source ↗Coverage spans all seven A/B MAC contractors — Noridian, CGS, First Coast, NGS, Novitas, Palmetto GBA and WPS — across the 12 A/B jurisdictions, plus the DME MAC LCDs issued jointly by Noridian and CGS across the 4 DME jurisdictions. Their Local Coverage Determinations and Billing & Coding Articles are published to the CMS Medicare Coverage Database, which is where we read them.
Federal Register
Visit source ↗Proposed and final rules — Physician Fee Schedule, OPPS, IPPS, ESRD — read for the provisions that change coverage or payment.
Office of Inspector General (OIG)
Visit source ↗OIG Special Fraud Alerts and advisory guidance, which signal the billing and coding arrangements under federal enforcement scrutiny.
U.S. Food & Drug Administration (FDA)
Visit source ↗Drug and biological approvals with billing implications — new products that drive new HCPCS/J-codes and coverage questions.
NLM Clinical Tables API — ICD-10-CM & HCPCS
Visit source ↗Authoritative, free code definitions from the National Library of Medicine, powering the code lookup tool and linked to CMS and CDC source documentation.
CMS NCCI edits & fee schedules
Visit source ↗National Correct Coding Initiative edits and the Physician Fee Schedule / OPPS pricing files that change correct coding and payment.
Also under watch — not yet a source of alerts
A separate monitoring service reads the endpoints below and records what it finds, with the source link, for review. Nothing here reaches your feed on its own. An item becomes an alert only if it passes the same verification and scoring the sources above go through — so this section widens what we watch, and changes nothing about what we have published.
Federal Register — public inspection (CMS)
Visit source ↗The public-inspection desk, filtered to CMS: documents that are on file and scheduled for publication but not yet published in the Federal Register. We watch this endpoint and stage what it returns; it is a monitoring source, not a source of alerts.
Monitored — watched and recorded; not an ingestion path for alerts.
eCFR — 42 CFR amendment log
Visit source ↗Change detection on the regulatory text itself. 42 CFR is where the Medicare programme rules live, including §405.1801 and §405.1803 — contractor determination and notice of amount of programme reimbursement, which is the MAC process described at the source of law rather than in a contractor's summary of it.
Monitored — watched and recorded; not an ingestion path for alerts.
CMS sitemap change signal — coverage, LCD, NCD and transmittal pages
Visit source ↗Per-URL modification timestamps published by CMS, filtered to the coverage, LCD, NCD and transmittal paths. This is how we notice that a coverage determination was newly published or revised — the enrichment path only ever sees determinations already in the corpus, so without this nothing detects a new one. Only the timestamps are read; no page content is fetched through this route.
Monitored — watched and recorded; not an ingestion path for alerts.
Freshness & verification
All sources are ingested and signal-scored every business day, and source links are verified at ingestion. You can see the live ingestion status — including the last run and the 1,600+ alerts on record — at /data-status. The 1,600+ figure counts published alerts only; the watched sources above are deliberately not in it. For how those sources are scored and verified, see our methodology.
