CMS CLIA Laboratory Scraper - Certification & Lab Leads

Search the official CMS Provider of Services File - Clinical Laboratories (CLIA) and return normalized, source-linked laboratory evidence. Use it for laboratory directory research, healthcare compliance preflight, provider-data QA, market mapping, and lab lead generation.

No CMS API key, login, browser, or proxy is required.

What you can search

• Exact 10-character CLIA number
• Facility/address keyword
• State, exact city, or ZIP code
• Certificate of Compliance, Waiver, Accreditation, Provider-Performed Microscopy, or Registration
• Active, terminated/inactive, or all snapshot records
• Hospital, independent lab, physician office, pharmacy, public-health lab, mobile lab, and the other official CMS facility types
• CMS accreditation matches for A2LA, AABB, AOA, ASHI, CAP, COLA, or the Joint Commission
• Minimum application-reported annual test volume
• Sort by facility name, reported volume, or certificate effective date

Empty input uses a fast deterministic active accredited hospital-laboratory example. For broad searches, maxCandidates bounds the source rows checked before local volume/status filtering and sorting; every row states whether that bound applied.

Output

Found records include:

• CLIA number and facility name
• Active/terminated snapshot status plus decoded status reason
• Certificate type, effective date, mailed date, and expiration/termination date
• Facility and ownership types
• Physical address, city, state, ZIP, public phone, and fax
• Region, county/FIPS, CBSA, and urban/rural evidence
• Accreditation match organizations, reported codes, and match dates
• Applicable CMS-116/CMS-1557, waived, and PPMP reported test volumes
• Affiliated CLIA numbers and directly affiliated lab count
• Multiple-site, hospital-lab, nonprofit, temporary-site, and shared-lab indicators
• Change-of-ownership evidence
• Source query count, candidate bound, retrieval time, official CMS links, data dictionary, and interpretation caveats

No-match and source-unavailable outcomes are explicit dataset items rather than silent empty datasets.

Important interpretation limits

This actor uses CMS's official quarterly Provider of Services CLIA administrative snapshot. It is useful evidence, but it is not:

• a real-time certification or renewal decision;
• a laboratory quality, proficiency-testing, sanctions, or inspection rating;
• proof that an accreditor currently considers a laboratory in good standing;
• proof that application-reported test volume equals current or audited throughput;
• a complete laboratory, ownership, compliance, or due-diligence report.

Records can lag, change, contain administrative codes, or reflect application data. A missing row does not prove that a laboratory does not exist, is unlicensed, is inactive, or lacks another identifier. Confirm consequential decisions with CMS, the applicable state agency, and the relevant accrediting organization.
