How To Apply For An NPI Number for Optometry

What is an NPI Number?

It’s simple, an NPI = National Provider Identifier. It is a unique 10-digit identification number issued to health care providers in the USA by the Centers for Medicare and Medicaid Services (CMS).

Why do you need an NPI Number?

  • Because health care plans are required to identify you, an optometrist, by your NPI number. Also you must have an NPI for use in all HIPAA transactions.
  • You can use it as an identifier on prescriptions, although your NPI is NOT your license number.
  • Your EMR system can identify you and the patient records you worked on with this NPI number.
  • To keep a record of any unlawful activity as a health care practitioner.
