Reading this record

Beyond the primary code the record carries Optometrist and Ophthalmology, Retina Specialist, which is the registry's own signal that the practice covers more than routine work. 2 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 April 2022. That is neither fresh nor ancient by the standards of this metro, where 3 of 39 records were updated in 2024 or later and 23 predate 2020.

For local context: Rapid City holds 36 registered eye care practices in this snapshot, 28 of them optometry and 8 ophthalmology, in ZIP codes including 57701. 26 of them took an NPI before this practice did. The closest is Slingsby & Wright Eye Care LLC in Rapid City, 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 South Dakota boards hold the licensing record, and the practice itself is the only source for what it charges today.

3 other organizations hold an NPI at the same street address. Shared suites and multi-specialty buildings are common, and it is worth knowing which entity you are actually booking with.

What to expect to pay at an ophthalmology practice like this

The NPI registry holds no prices, so nothing here is a quote from Slingsby & Huot Eye Associates Prof. 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 31 optometry practices on the Rapid City page if you only need a prescription.
