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 13 of 65 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The NPI registry holds no prices, so nothing here is a quote from Riverside Eye, and independent optometry practices do not publish fee schedules. Customers report paying $120 to $200 at this kind of practice without insurance, which is a reported band rather than a published price. The nearest published figure is $95, the median starting fee across the 1,280 US retail optical stores that print one (30 September 2026), and Medicare pays $149.64 for a comprehensive new-patient exam (CPT 92004). Ask Riverside Eye for its self-pay price.
Ask two things when you call: whether the quoted fee includes the refraction, and what a contact lens fitting adds if you wear lenses (the median published contact-lens fee is $129). A comprehensive exam is $80 to $120 at the middle half of stores that print a price. If price is the deciding factor, the 65 practices on the Chattanooga page give you the full local field to call around.
