Reading this record

Beyond the primary code the record carries Optometrist, which is the registry's own signal that the practice covers more than routine work. The entry was last refreshed in May 2022. That is neither fresh nor ancient by the standards of this metro, where 305 of 1,867 records were updated in 2024 or later and 1,085 predate 2020.

For local context: Pasadena holds 34 registered eye care practices in this snapshot, 11 of them optometry and 23 ophthalmology, in ZIP codes including 91101. 26 of them took an NPI before this practice did. The closest is Diamond Vision Optometry Inc in Pasadena, 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 Diamond Vision Optometry Associates and Gtc Optometry. 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.
