TPI, or Texas Provider Identifier, was a unique 9-digit number assigned to healthcare providers participating in Texas state health programs, including Medicaid. The TPI number was used to identify providers in the billing process in order to ensure that claims were processed correctly and efficiently, particularly for Medicaid claims.
Key Points
- The TPI (Texas Provider Identifier) number is a 9-digit healthcare provider identifier used for billing in the Texas Medicaid Program. Until September 1, 2021, it was a reliable and solid form of identification.
- Neurologists and other providers have relied on TPI for their medical billing needs, but it has been replaced by NPI to keep things simple.
- The TPI is no longer required for claims, as NPI is the standard, and neurology practices will need to update their billing systems ASAP.
History and Transition
Initially implemented as part of Texas’s provider management system, TPI was used in conjunction with the federally mandated National Provider Identifier (NPI), which became a requirement for all U.S. providers in 2007. On September 1, 2021, the Texas Medicaid and Healthcare Partnership (TMHP) announced that TPI was no longer required for claim submissions and/or prior authorization. All billing must be completed via NPI for all providers to streamline and standardize all billing.
Relevance to Neurology Medical Billing
For Texas neurologists, TPI was your billing buddy until the swap, but now you need to update your systems to use NPI in your neurology medical billing to ensure you’re not violating the rules with those pesky claim denials. Neurology medical billing can be tricky due to specialty coding for brain and nerve conditions. Now you have to consider the transition as well, which requires precise documentation and updated procedures.
Survey Note: TPI Number in Medical Billing and Its Importance to Neurology Practices in Texas
This survey note provides an in-depth analysis of the TPI number in medical billing and its relevance to neurology practices in Texas. The information contained in this note has been researched and announced by the relevant authority. It provides a comprehensive view of TPI number to medical providers and billing professionals.
Background and Definition
The TPI number is a 9-digit identifier that was assigned to healthcare providers who participate in Texas state health programs, including the Texas Medicaid Program. It was used as a billing identifier to ensure proper processing of claims related to services rendered by participating healthcare providers, including neurologists. The TPI number was essential for doing business with Texas Medicaid, as claims were filed and submitted based on this identifier. It also assisted in maintaining program compliance.
Background and History
The exact date TPI started is unknown, but it was a part of Texas’s direct provider identifier system before the National Provider Identifier (NPI) was implemented. The NPI, which was required by the Centers for Medicare & Medicaid Services (CMS) in 2007, is a standardized identifier for providers throughout the country. Until recently, neurologists and other Texas providers were required to maintain both TPI and NPI numbers. On September 1, 2021, TMHP announced that TPI numbers were no longer required for paper claims, prior authorization requests, and TMHP correspondence (TPI Number Removed From Claim Forms). In February 2022, TMHP sent a reminder that the transition period ended on November 30, 2021 and that the NPI should be used for all billing activities (Reminder: TPI Number Removed).
The reason for this standardization is simple: life’s much easier when you use one identifier. NPI is used by all health plans, so why complicate things with multiple identifiers? Some sites, such as What Is TPI Number in Medical Billing, still claim that TPI is a “key identifier,” but they are simply outdated given the announcements from TMHP. TPI may still appear in some resources for the revalidation of provider enrollment (e.g., TMHP resources (Revalidation TPI table)), but it should not be used on claims for billing purposes.
Impact on Neurology Medical Billing
Neurology medical billing is unique because conditions affecting the brain and nerves like epilepsy, dementia, and chronic pain management can quickly become complicated. Neurology coding often requires specific ICD-10 and CPT codes. Historically, Texas neurologists submitted Medicaid claims using TPI numbers, just like other providers. However, with the transition to NPI, neurology practices will be impacted by NPI and will need to update their billing systems and ensure that the appropriate identifiers are used. This is a critical step in avoiding claim denials, which can be particularly problematic for neurological services due to the detailed documentation required for neurological billing services, as stated in Neurology Medical Billing Services.
Some of the challenges in neurology medical billing include:
- Complexity of coding for neurologic procedures such as EMGs and nerve conduction studies, such as 95816–95819 (Neurology Medical Billing).
- Payor requirements for documentation, which can be quite strict, and will impact your payment and reimbursement, as described in Coding and billing issues in hospital neurology compensation.
- Reimbursement Variability: Tracking rates changes will be important for financial planning moving forward.
As a result of this change, neurologists should make sure their enrollment records are up to date (such as following TMHP’s provider enrollment instructions (Provider Enrollment Instructions)) and adjust their billing practices to ensure business continuity. While the transition to NPI will standardize many processes, it is still another change neurology practices will need to manage and could potentially impact revenue downstream if not properly managed.
TPI vs. NPI: What’s the Difference?
To illustrate the difference, let’s take a look at this table of TPI and NPI characteristics:

This table really highlights the evolution toward a single system, and that is very exciting for neurology clinics who want to make their operations more efficient.
Current Status and Future Implications
As of March 4, 2025, TPI will be defunct for billing purposes, and NPI will be the new standard. Neurology practices will need to continue to adapt to ensure billing accuracy, especially since this is a specialty that is so complex. Resources such as Specialized Neurology Medical Billing Services highlight the importance of having the right billing support to help navigate these changes, minimize denials, and maximize revenue.
The future is likely to be NPI-based, with the potential to integrate technology such as EHR systems to make neurology medical billing even more efficient. BillingParadise offers this as well. Neurologists should stay informed by following TMHP announcements and using billing services to overcome the challenges.
Conclusion
This survey note confirms that TPI, which was once widely used for medical billing in Texas, including neurology practices, has been replaced by NPI since September 2021. While standardizing the process, this change forces neurologists to adjust their billing systems and ensures compliance to help with efficient neurology medical billing. Providers can now better manage the financial aspects of their practice, so they can focus on taking care of patients instead of billing.
