Reading this record
CMS records this location as a subpart of Nathan T. DO, O.D. APC, meaning it bills under its own NPI but belongs to a larger organization. The entry was refreshed in November 2025, putting it among the 305 of 1,867 Los Angeles-Long Beach-Anaheim records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.
For local context: Santa Ana holds 42 registered eye care practices in this snapshot, 25 of them optometry and 17 ophthalmology, in ZIP codes including 92704. 36 of them took an NPI before this practice did. The closest is Santa Ana Family Optometry in Santa Ana, 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 California 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 optometry practice like this
The NPI registry holds no prices, so nothing here is a quote from Nathan T. DO, O.D. APC. Based on this site's own price research, an independent optometry practice typically charges $120 to $200 for an exam without insurance, against a national average of about $136 and roughly $25 once a vision plan pays its share.
Ask two things when you call: whether the quoted fee includes the refraction, and what a contact lens fitting adds if you wear lenses, since that takes a visit to $150 to $370. A comprehensive exam is $100 to $250. If price is the deciding factor, the 1,867 practices on the Los Angeles-Long Beach-Anaheim page give you the full local field to call around.
