Reading this record
Beyond the primary code the record carries Ophthalmology, which is the registry's own signal that the practice covers more than routine work. The entry was refreshed in May 2026, putting it among the 68 of 326 San Antonio-New Braunfels records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.
For local context: San Antonio holds 241 registered eye care practices in this snapshot, 173 of them optometry and 68 ophthalmology, in ZIP codes including 78216. 172 of them took an NPI before this practice did. The closest is Thomas Omar Oei MD PA in San Antonio, 0.0 miles away.
None of this is a licensing check. CMS issues an NPI so a provider can be identified in billing transactions, and states plainly that issuance does not ensure or validate that the holder is licensed or credentialed. The Texas boards hold the licensing record, and the practice itself is the only source for what it charges today.

What to expect to pay at an ophthalmology practice like this
The NPI registry holds no prices, so nothing here is a quote from Duncan A Friedman MD PA. Based on this site's own price research, an ophthalmology practice typically charges $150 to $300 or more for an exam without insurance, against a national average of about $136 and roughly $25 once a vision plan pays its share.
Ophthalmology visits are usually medical rather than routine, which changes who pays: medical insurance and Medicare Part B cover a medically necessary exam, while a routine refraction for glasses is normally not covered. Ask whether the visit will be billed as medical or routine before you book, and compare with the 245 optometry practices on the San Antonio-New Braunfels page if you only need a prescription.
