Duplicated PROVIDER.NPI

CDM or THEMIS convention?

THEMIS

Table or Field level?

Provider Table

Is this a general convention?

Table

Summary of issues

• While we should only have one records per provider in the PROVIDER table it is possible for the NPI to be duplicated.

Summary of answer

Adding THEMIS rule to the effect:
The PROVIDER table contains a list of uniquely identified healthcare providers. However, duplicate NPI numbers may occur because the source data might provide the NPI representing the care site rather than the individual provider's NPI. NPI should not represent a primary key within the PROVIDER table.

• Provider table
• Seems to be a fair amount of discussion about what happens when you have multiple records for one provider with same NPI

Other comments/notes

• NPI = National Provider Identifier
• not a primary key, it can be duplicated, but each provider should only have one record in the provider table.

@ericaVoss I updated the wording to match the CDM table description.
