Reading this record

The practice bills under the legal name Johns Hopkins University and registered Jhu - Wilmer Eye Institute as its trading name, so an insurance statement may show a name that does not match the sign on the door. Beyond the primary code the record carries Optometrist, Ophthalmology, Glaucoma Specialist and Ophthalmology, Retina Specialist, which is the registry's own signal that the practice covers more than routine work. CMS records this location as a subpart of Johns Hopkins University, meaning it bills under its own NPI but belongs to a larger organization. 24 locations nationally are registered under the same name, so pricing and policies are likely to be set at group level rather than at this office. The entry was last refreshed in October 2022. That is neither fresh nor ancient by the standards of this metro, where 201 of 497 records were updated in 2024 or later and 208 predate 2020.

For local context: Baltimore holds 137 registered eye care practices in this snapshot, 78 of them optometry and 59 ophthalmology, in ZIP codes including 21264. No other practice in the city took its NPI earlier than this one, which makes it the longest-registered address here. The closest is Jhu - Wilmer Eye Institure/Od's in Baltimore, 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 Maryland 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 ophthalmology practice like this

The NPI registry holds no prices, so nothing here is a quote from Jhu - Wilmer Eye Institute. Based on this site's own price research, an ophthalmology practice typically charges $150 to $300 or more for an exam without insurance, against a national average of about $136 and roughly $25 once a vision plan pays its share.

Ophthalmology visits are usually medical rather than routine, which changes who pays: medical insurance and Medicare Part B cover a medically necessary exam, while a routine refraction for glasses is normally not covered. Ask whether the visit will be billed as medical or routine before you book, and compare with the 315 optometry practices on the Baltimore-Columbia-Towson page if you only need a prescription.
