Reading this record

The practice bills under the legal name Johns Hopkins University and registered Jhu - 620 Boulton St - Provider Type: 20 - Physician as its trading name, so an insurance statement may show a name that does not match the sign on the door. 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 refreshed in March 2026, putting it among the 201 of 497 Baltimore-Columbia-Towson records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.

For local context: Bel Air holds 16 registered eye care practices in this snapshot, 11 of them optometry and 5 ophthalmology, in ZIP codes including 21014. 15 of them took an NPI before this practice did. The closest is Parris Castoro Eye Care Center, P.A. in Bel Air, 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 - 620 Boulton St - Provider Type: 20 - Physician. 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.
