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 325 of 1,876 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 43 registered eye care practices in this snapshot, 26 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.
Also registered at this address
2 other organizations hold an NPI at the same street address. Shared suites and multi-specialty buildings are common, and it is worth knowing which entity you are actually booking with.

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registry holds no prices, so nothing here is a quote from Nathan T. DO, O.D. APC, and independent optometry practices do not publish fee schedules. Customers report paying $120 to $200 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 Nathan T. DO, O.D. APC for its self-pay price.
Ask two things when you call: whether the quoted fee includes the refraction, and what a contact lens fitting adds if you wear lenses (the median published contact-lens fee is $129). A comprehensive exam is $80 to $120 at the middle half of stores that print a price. If price is the deciding factor, the 1,876 practices on the Los Angeles-Long Beach-Anaheim page give you the full local field to call around.
