How to get an NPI number in Mississippi

The NPI (National Provider Identifier) is a federal number, so there is no Mississippi NPI: one 10-digit number from CMS works in Mississippi and every other state, for life. What is Mississippi-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 Mississippi lookup below first in case you already have one.

What is Mississippi-specific

Your license number: The application asks for your Mississippi license number and the issuing state (MS). Enter it exactly as Mississippi State Department of Health (MSDH), Professional Licensure Division lists it; the Mississippi license lookup shows the exact format. No umbrella agency. MSDH licenses only a limited set of professions (occupational therapists, speech-language pathologists/audiologists, respiratory care, dietitians, athletic trainers, art/music therapists, hearing aid specialists, radiation technicians, CNAs, etc.) and its lookup covers only those. Nurses, physicians, pharmacists and most other professions are licensed by separate state boards.
Mississippi Medicaid: Medicaid enrollment in Mississippi starts with the NPI. Once you have it, enroll with Mississippi Medicaid.
VA Community Care: In Mississippi 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.
