December 2016 Texas Medicaid Provider Procedures Manual

Section 1: Provider Enrollment and Responsibilities : 1.1 Provider Enrollment and Reenrollment : 1.1.1 NPI and Taxonomy Codes

1.1.1
The NPI final rule, Federal Register 45, Code of Federal Regulations (CFR) Part 162, established the NPI as the standard unique identifier for health-care providers and requires covered health-care providers, clearinghouses, and health plans to use this identifier in Health Insurance Portability and Accountability Act (HIPAA)-covered transactions. An NPI is a 10-digit number assigned randomly by the NPPES. An NPI must be obtained before a provider can enroll as a Texas Medicaid provider.
An NPI is not required for enrollment for certain provider types; however, the provider must submit a signed letter on company letterhead that attests that they are not a health-care provider and are unable to obtain an NPI.
The Health Care Provider Taxonomy Code Set is an external, non-medical collection of alphanumeric codes designed to classify health-care providers by provider type and specialty. Providers may have more than one taxonomy code. (Taxonomy codes can be obtained from the Washington Publishing Company website at www.wpc-edi.com).
During the enrollment process, providers must select a primary and, if applicable, secondary taxonomy code associated with their provider type. Providers will be supplied a list of taxonomy codes to choose from that correspond to the services rendered by the type of provider they wish to enroll as. Only the code will be displayed. Due to copyright laws, TMHP is unable to publish the taxonomy description. Therefore, providers must verify the taxonomy code associated with their provider type and specialty before beginning the online attestation process.
