Texas Medical Board crosswalk

Join method for this NPI: license. The crosswalk file is data/datos5/matches.json, built from NPPES license strings against Texas open data set tm3v-pfq9. Date of that file: 2026-11-09.

The crosswalk marks currently_licensed as Y. License number on the matched row: M3313. registration_status: ACTIVE. license_status: NONE.

disciplinary_status is NONE on the matched row. A value of NONE means the field was NONE in the file, not a promise about future complaints.

TMB practice_city on the matched row is SAN ANTONIO. The street on this page is the NPPES LOCATION address in San Antonio. They are different fields and this site does not merge them into one story.

NPPES does not prove a state license. That is why the TMB field is shown next to the NPI. If the fields disagree, both are shown and neither is smoothed over.

What this page does not show

This build does not have a CMS Medicare assignment file, so it does not say whether the clinician accepts Medicare or Medicare Advantage. It does not have a confirmed language field, office hours, hospital privileges, or a quality score.

There is no rating, no ranking, and no 'best' list. The profile is not claimed. Nothing on this page is a diagnosis or a recommendation to start, stop, or change care.

To check the license, use the Texas Medical Board public lookup and the NPI Registry. This website is not those agencies.
