NPI - Payers


NPI Readiness
Availity is making every effort to confirm and communicate the status of our connected payers. For our most up-to-date list, please review the NPI Readiness of these payers.


NPI Readiness

The options of NPI readiness are as follows:

  2. Dual ID
    Allows all of the following scenarios:
    1. NPI only

    3. NPI and Legacy identifiers


  3. NPI per Mandate.
    • NPI required per mandate under HIPAA regulations
    • Legacy identifier not allowed
  4. NPI per Mandate. Legacy ID also allowed.
    • NPI required per mandate under HIPAA regulations
    • Legacy identifier also allowed

Atypical Providers

An atypical provider does not provide any health-related services, such as taxi and construction companies. Atypical providers are not eligible to obtain an NPI. Availity will continue to accept the Tax ID or existing Legacy ID as the primary identifier for atypical providers.

Atypical providers must register with Availity before they can begin to submit to a payer that requires an NPI. This registration allows Availity to relax the NPI requirement in order to properly pass the transaction to the payer. Availity has no way of knowing every impacted payer, and therefore cannot notify payers of a provider’s atypical status.

Atypical providers have been directed to notify applicable payers of their status so that transactions are not rejected by the payer for a missing NPI.
