National Provider Identifier (NPI) FAQ
Dentists, please send us your NPI by filling out this form so we can update our files.
Do I need to take any action?
If you are a provider who submits electronic claims, you must apply for an NPI and understand the requirements for its use.
What is the NPI?
The National Provider Identifier (NPI) is part of the Health Insurance Portability and Accountability Act (HIPAA). The NPI regulation establishes one unique identifying number for each health care provider. This simplification measure will pare down the number of identifiers currently used in health care transactions.
What are the advantages of the NPI?
Use of the NPI will have several advantages, including:- One unique provider identifier for all health plans to utilize
- A permanent provider identifier that will not change in the event of practice relocation or changes in specialty
- An easier process for health plans to track transactions and avoid duplication
How is my NPI determined?
The NPI is a random ten-digit number (nine digits plus a check digit to detect keying errors). It never expires. It contains no inherent information about the provider, such as state of residence or license number. NPI numbers are administered by the Centers for Medicare and Medicaid Services (CMS), which has contracted with the National Plan and Provider Enumeration System (NPPES). The federal government is also responsible for assisting providers in completing the application and resolving problems associated with an NPI.
Who is required to apply for an NPI?
All health care providers are eligible to receive an NPI. However, only "Covered Entities" are required to obtain an NPI. A dental provider is a "Covered Entity" if he or she transmits electronic transactions governed by HIPAA, primarily electronic claim transactions.
The broad definition of health care "provider" in the federal regulation encompasses all who provide health care services:
- Individuals - such as physicians, dentists and pharmacists
- Organizations - such as hospitals and clinics
Although dental assistants and hygienists are "providers" and are thus eligible to obtain an NPI, they are only required to do so if they submit claims for their services.
What if I only submit paper claims?
If you do not submit electronic claims, you are not required to obtain an NPI (except in Minnesota, where providers must submit NPIs on both paper and electronic claims by the federal deadline). However, Securian Dental strongly encourages you to obtain and use an NPI, once we are prepared to accept it. This will enable you to maintain only one unique identifier for use with all payers.
When is the deadline?
All HIPAA "Covered Entities" must use NPIs on all claims by May 23, 2007. To ensure a smooth transition, providers are urged to apply for their NPI well in advance of the compliance date.
Clearinghouses are also required to be able to accept and transmit the NPI by May 23, 2007.
Will the NPI replace other numbers I use?
The NPI will replace other identifying numbers currently used in electronic transactions, such as your: - Numbers issued by plans and insurers (e.g. Blue Cross and Blue Shield number)
- Medicaid provider number
- Medicare provider number
- CHAMPUS number
- Other "legacy" identification numbers
The NPI will not replace numbers used for purposes other than general identification, such as your:
- Social Security Number
- DEA number
- Taxpayer ID number
- Taxonomy number
- State license number
The NPI will replace all other identification numbers, but your Taxpayer ID number (or Social Security Number) will still be required for 1099 purposes.
How do I apply for my NPI?
You only apply for your NPI once, and your NPI is permanently assigned for your lifetime. There is no cost to apply.
You may apply for your NPI either:
- Online: Complete a web application and submit it electronically
- On Paper: To request a paper application, call NPPES at (800) 465-3203.
When you apply for your NPI, you will be asked to provide your 10-digit taxonomy code. For quick reference, here are the dental taxonomy codes:
- General Practice-1223G0001X
- Dental Public Health-1223D0001X
- Endodontics-1223E0200X
- Oral and Maxillofacial Pathology-1223P0106X
- Oral and Maxillofacial Radiology-1223X0008X
- Oral and Maxillofacial Surgery-1223S0112X
- Orthodontics and Dentofacial Orthopedics-1223X0400X
- Pediatric Dentistry-1223P0221X
- Periodontics-1223P0300X
- Prosthodontics-1223P0700X
- Denturist-122400000X
After you receive your NPI, you must furnish any updates to the NPPES. If any of the data you submitted on your application changes, notify NPPES within 30 days of the change.
You may receive notices about the NPI from other health and dental plans, but your unique NPI is used with all plans. Remember to notify each dental plan of your NPI separately.
What do I do with my NPI once I have it?
If you haven’t done so already, please send us your NPI now so it won’t affect your claims. Please remember to continue to include your TIN and License on the claim.
Other health and dental plans may have differing timelines for NPI implementation, so take notice of each plan's requirements.
In addition, you will want to contact your clearinghouse for instructions about their transition plans for using the NPI.
