Reading this record
Beyond the primary code the record carries Optometrist, Corneal and Contact Management, which is the registry's own signal that the practice covers more than routine work. The entry was last refreshed in October 2022. That is neither fresh nor ancient by the standards of this metro, where 44 of 258 records were updated in 2024 or later and 169 predate 2020.
For local context: Sunnyvale holds 15 registered eye care practices in this snapshot, 11 of them optometry and 4 ophthalmology, in ZIP codes including 94087. 10 of them took an NPI before this practice did. The closest is Silicon Valley Eye Physicians in Sunnyvale, 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 Mendelson & Mark Optometric Corporation. 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 258 practices on the San Jose-Sunnyvale-Santa Clara page give you the full local field to call around.
