Updated Taxonomy Codes Effective for Some Medicaid and CSHCN Services Program Providers on April 1, 2021

Last updated on 2/23/2021

Note: Texas Medicaid managed care organizations (MCOs) must provide all medically necessary, Medicaid-covered services to eligible clients. Administrative procedures such as prior authorization, pre-certification, referrals, and claims/encounter data filing may differ from traditional Medicaid (fee-for-service) and from MCO to MCO. Providers should contact the client's specific MCO for details.

Effective April 1, 2021, some taxonomy code descriptions will be updated for some behavioral health and social service provider types, community/behavioral health agency provider types, and transportation services provider types for Texas Medicaid and the Children with Special Health Care Needs Services Program.

Providers can log into the Provider Information Management System (PIMS) to make updates to their taxonomy code.

The descriptions of the following Taxonomy Codes were changed:
