Reading this record
The practice bills under the legal name Robert J S Mack, MD PC and registered Mack Eye Center 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 December 2022. That is neither fresh nor ancient by the standards of this metro, where 198 of 1,321 records were updated in 2024 or later and 796 predate 2020.
For local context: Hoffman Est holds 1 registered eye care practice in this snapshot, 0 of them optometry and 1 ophthalmology, in ZIP codes including 60169. No other practice in the city took its NPI earlier than this one, which makes it the longest-registered address here. The closest is Ophthalmic Consultants of Chicago, LLC in Hoffman Estates, 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 Illinois 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The NPI registry holds no prices, so nothing here is a quote from Mack Eye Center, and ophthalmology practices do not publish fee schedules. Customers report paying $150 to $300 or more 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 Mack Eye Center for its self-pay price.
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 1,038 optometry practices on the Chicago-Naperville-Elgin page if you only need a prescription.
