Reading this record

The practice bills under the legal name Alisha Niswonger, OD LLC and registered Riverside Eye 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 February 2023. That is neither fresh nor ancient by the standards of this metro, where 11 of 64 records were updated in 2024 or later and 38 predate 2020.

For local context: Hixson holds 13 registered eye care practices in this snapshot, 11 of them optometry and 2 ophthalmology, in ZIP codes including 37343. 12 of them took an NPI before this practice did. The closest is Hixson Eyecare in Hixson, 2.0 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 Tennessee 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 Riverside Eye. 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 64 practices on the Chattanooga page give you the full local field to call around.
