Reading this record
The practice bills under the legal name Zachary Jost OD Inc PC and registered Back Bay Eye Care as its trading name, so an insurance statement may show a name that does not match the sign on the door. The entry was last refreshed in September 2023. That is neither fresh nor ancient by the standards of this metro, where 103 of 632 records were updated in 2024 or later and 355 predate 2020.
For local context: Boston holds 61 registered eye care practices in this snapshot, 39 of them optometry and 22 ophthalmology, in ZIP codes including 02116. 55 of them took an NPI before this practice did. The closest is Gsm Park Square, LLC in Boston, 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 Massachusetts 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 Back Bay Eye Care. 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 632 practices on the Boston-Cambridge-Newton page give you the full local field to call around.
