Methodology
How we build this site, what we verify, and what we do not.
Summary
We aggregate the public NPPES (National Plan and Provider Enumeration System) registry published by CMS and organize it by city, state, and NPPES specialty. We do not verify licenses or complaints ourselves — for that, we link directly to each state chiropractic board.
Data Pipeline
- Ingest. We download the NPPES bulk file from CMS (updated monthly) and filter to individual providers (Entity Type 1) whose primary taxonomy starts with 111N (Chiropractor).
- Normalize. We standardize address fields, format phone numbers, and compute years since NPI enrollment (from the NPPES enumeration date).
- Attach specialty only when NPPES supports it. Some NPPES taxonomy codes indicate a chiropractic specialty (e.g., 111NN0400X = Neurology, 111NP0017X = Pediatric). We label those. The generic chiropractor taxonomy (111N00000X, the most common) is NOT labeled with a specialty.
- Group by city and state; link to state boards. Every profile links to the correct state chiropractic board for authoritative license lookups.
What We Publish
Only fields that appear in the NPPES public bulk file:
- Provider first and last name
- Credential (DC — Doctor of Chiropractic)
- NPI number and taxonomy code
- NPPES-declared specialty when a specialty-specific taxonomy code applies
- Practice-location address, ZIP code, and phone
- NPI enumeration date and years since NPI enrollment
What We Deliberately Do NOT Publish or Claim
License status.
NPPES does not publish license status. Use the state chiropractic board link on every profile to verify current status.
Disciplinary or complaint history.
NPPES does not publish complaints. State boards do. We link there rather than republish.
Clinical years of experience.
"Years on NPPES" is time since CMS issued the NPI, not clinical practice years.
Practice name for individual NPIs.
We only display a practice name when NPPES has a real "Provider Organization Name" field. We do not fabricate one.
Trust scores, rankings, endorsements.
We do not score, rank, or endorse individual chiropractors.
Corrections and Removal
Providers may request correction or removal via our contact page. We honor takedown requests within 1 week.
