How to get an NPI number in Oklahoma

The NPI (National Provider Identifier) is a federal number, so there is no Oklahoma NPI: one 10-digit number from CMS works in Oklahoma and every other state, for life. What is Oklahoma-specific is the license number you enter, the Medicaid program you may enroll in next, and who runs VA Community Care here.

Short answer: fill out SimpleNPI's short form and the application is filed with CMS for free; the NPI usually arrives by email and text, with all the documentation, within 10 minutes. Or apply yourself for free at nppes.cms.hhs.gov. Either way, check the Oklahoma lookup below first in case you already have one.

What is Oklahoma-specific

SoonerCare: Medicaid enrollment in Oklahoma starts with the NPI. Once you have it, enroll with SoonerCare.
VA Community Care: In Oklahoma the VA's Community Care Network is administered by Optum (Region 3). Optum credentials community providers by NPI, so the NPI comes before the credentialing application.
