NPI lookup
Search an NPI number
Enter a 10-digit NPI or provider name to review CMS NPI Registry identity fields with source dates and OIG LEIE screening context.
Identifier
10-digit NPI
CMS describes the NPI as an intelligence-free numeric identifier, so do not infer state or specialty from the number alone.
Official source
CMS NPI Registry
Registry records can include entity type, taxonomy, enumeration date, last-updated date, and public address context.
Review limit
Not credentialing
NPI issuance does not validate licensure, credentialing, Medicare enrollment, or current practice authority.

How an NPI registry lookup should be read
Last verified: 2026-06-07. date_retrieved: 2026-06-07. CMS describes the NPI as a 10-digit identifier for covered health care providers, and the number itself does not encode the provider's state or medical specialty. SourceCheckHealth uses the exact NPI or name search to open the registry record, then keeps taxonomy, address purpose, source dates, and OIG LEIE screening context separate.

The example result shows how an individual NPI profile keeps registry identity, taxonomy, address context, cache timestamps, and OIG match confidence on the same page without treating the record as clearance.

NPI lookup fields and review limits
A useful NPI lookup separates the identifier from the registry fields that explain it. Use this table to avoid reading more into the number than CMS publishes.
| Lookup question | Source signal | What to verify next |
|---|---|---|
| Is this the exact provider identifier? | A 10-digit NPI from CMS NPI Registry or NPPES. | Confirm the number belongs to the provider or organization being reviewed. |
| What kind of provider record is it? | Entity type, primary taxonomy, enumeration date, and last-updated date. | Use taxonomy as classification context, not proof of current practice authority. |
| Where is the public contact context? | Registry address purpose and public address rows when present. | Compare mailing or practice address context with current official records. |
| Does the NPI clear exclusion screening? | OIG LEIE exact or possible match context shown beside the NPI record. | Verify any possible match in official OIG systems before acting. |

Practical notes
What does an NPI lookup by number show?
It shows the public NPI Registry identity fields available for that 10-digit NPI, including entity type, taxonomy, source dates, public addresses, and related OIG LEIE screening context.
Does an NPI record validate licensure?
No. NPI data does not validate licensure, credentialing, Medicare enrollment, or current practice authority.
How should I use an NPI registry lookup with OIG screening?
Use the NPI record to anchor identity and taxonomy, then review OIG LEIE exact or possible matches with the official source links before taking any compliance action.
Which CMS fields matter most in an NPI lookup by number?
Start with the exact 10-digit NPI, entity type, enumeration date, last-updated date, primary taxonomy, and public address purpose. SourceCheckHealth keeps those fields beside OIG context so reviewers can see what came from the CMS NPI Registry before checking other sources.
