Florida Medicaid: 2024 taxonomy rule changes

Effective Jan. 25, 2024, the Florida Agency for Health Care Administration (AHCA) is changing the taxonomy rules. This includes a new Taxonomy Master List (TML) and updates to some of the National Provider Identifier (NPI) Initiative tools and resources.

Take action

Please review the updated TML to make sure your taxonomy codes are accurate and up to date.

Remember to include the following information when submitting claims:

  • NPI number, as enrolled with Florida Medicaid
  • Taxonomy code for your services provided in accordance with your enrolled provider type and specialty
  • Address with ZIP+4 code, as enrolled with Florida Medicaid

The new TML will be used to authenticate billed taxonomy codes on claims to valid provider/specialty type. The TML works with the existing NPI Master List to ensure valid provider type/specialty type combinations.

NPI Initiative updates

This year, the NPI Initiative includes updates to:

  • NPI Mapping Logic
  • NPI to Medicaid ID Search Engine
  • Provider Master List (PML) (NPI crosswalk-related columns removed)
  • Pending Provider List (PPL) (NPI crosswalk-related columns removed)
  • Taxonomy Master List (TML)
