Updated Taxonomy Codes Effective for Some Medicaid and CSHCN Services Program Providers on March 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 March 1, 2021, some taxonomy codes will be updated for some hospital 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 following Taxonomy Codes have been modified for some hospitals:

283X00000X (A hospital or facility that provides health-related, social and/or vocational services to disabled persons to help them attain their maximum functional capacity.)

Note: This taxonomy will no longer be available for the enrollment of Rehabilitation Hospital Units. Currently enrolled providers impacted by this change will be given the appropriate Rehabilitation Unit Taxonomy – 273Y0000X.

Hospitals; Rehabilitation Hospital; Children


Short Term Hospital; General Acute Care Hospital

282N00000X (An acute general hospital is an institution whose primary function is to provide inpatient diagnostic and therapeutic services for a variety of medical conditions, both surgical and non-surgical, to a wide population group. The hospital treats patients in an acute phase of illness or injury, characterized by a single episode or a fairly short duration, from which the patient returns to his or her normal or previous level of activity.)

Long-Term Care Hospitals

282E00000X (Long-term care hospitals (LTCHs) furnish extended medical and rehabilitative care to individuals who are clinically complex and have multiple acute or chronic conditions.)
