Reading this record

Beyond the primary code the record carries Optometrist, Corneal and Contact Management, Optometrist, Low Vision Rehabilitation and Optometrist, Pediatrics, which is the registry's own signal that the practice covers more than routine work. 3 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 May 2026, putting it among the 133 of 375 Washington-Arlington-Alexandria records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.

For local context: Mitchellville holds 2 registered eye care practices in this snapshot, 2 of them optometry and 0 ophthalmology, in ZIP codes including 20721. No other practice in the city took its NPI earlier than this one, which makes it the longest-registered address here. The closest is Visual Eyes in Mitchellville, 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 optometry practice like this

The NPI registry holds no prices, so nothing here is a quote from Dr. Alexander C. Nnabue & Associates. 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 375 practices on the Washington-Arlington-Alexandria page give you the full local field to call around.
