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 71 of 328 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 242 registered eye care practices in this snapshot, 174 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The NPI registry holds no prices, so nothing here is a quote from Duncan A Friedman MD PA, and ophthalmology practices do not publish fee schedules. Customers report paying $150 to $300 or more at this kind of practice without insurance, which is a reported band rather than a published price. The nearest published figure is $95, the median starting fee across the 1,280 US retail optical stores that print one (30 September 2026), and Medicare pays $149.64 for a comprehensive new-patient exam (CPT 92004). Ask Duncan A Friedman MD PA for its self-pay price.
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 247 optometry practices on the San Antonio-New Braunfels page if you only need a prescription.
