What the record tells you
Dennis J Lazzara DDS MS LTD is an NPI registry record for a dental organization at 1129 Randall Court in Geneva, Illinois 60134. CMS issued NPI 1700952041 on 28 November 2006, and the practice last updated its own entry on 11 September 2025. That is recent, so the contact details are likely to be current.
It is registered under 2 dental taxonomy codes: Dentist (122300000X), Orthodontics and dentofacial orthopedics (1223X0400X). That puts it in 2 categories on this site, led by orthodontics. A practice that registers more than one category is telling CMS it does more than one kind of dental work at this address, which is why it has a page here rather than a row. No other address in the registry carries this name, though a practice trading under a chain brand often registers each office under its own legal name, so check the brand as well.
Geneva holds 16 registered dental practices inside the Chicago-Naperville-Elgin, IL-IN area, which has 4,610 in total on the Illinois side and ranks 1st in the state. 1 of the Geneva records also register orthodontics, so this is one of only a handful of local options in that category. Across the metro the mix runs general dentistry 69.1%, dental clinic or center 19.2%, orthodontics 6.2%. The closest other registered practices are Kurt W. Raack, M.S., D.D.S., P.C. (0.2 miles, Geneva), Randall Pointe Dental (0.4 miles, Geneva) and Thomas Skoumal DDS, PC (0.7 miles, Geneva), with 2 more inside 1 miles.
On our figures a routine adult cleaning in Illinois runs $110 to $165 cash and scaling and root planing $180 to $285 per quadrant, against a US average of $125. This practice's own prices are not in the registry and never will be: NPPES holds identifiers, not fees. Call (630) 232-2277 and ask for the cash price on code D1110, whether the exam and X-rays are included, and whether they run a membership plan if you have no insurance.

What to ask when you call
- The cash price for D1110, a routine adult cleaning, and whether the exam (D0120) and X-rays (D0274) are inside or outside that number.
- Whether you need scaling and root planing before a routine clean, and the per-quadrant price for D4341 or D4342 if so.
- Whether they run an in-house membership plan, and what it covers against what it costs a year.
- Whether they are taking new patients and how far out the next hygiene appointment is.
- The practice license, with your state dental board. An NPI is a billing identifier and proves nothing about licensing.

NPI registry records, status as reported by CMS in the August 2026 data dissemination file. NPPES is an identifier registry, not a license register: an NPI does not validate that a practice is licensed, accredited or currently open. Practices maintain their own NPPES entries. Every page shows the date the record was last updated; addresses and phone numbers are as self-reported and are not verified by us. This page describes a registry record.

Price figures are our own, last verified April 2026. State averages are our estimates compiled from FAIR Health regional cost data and CMS Medicare fee schedules; the ADA discontinued its national Survey of Dental Fees in 2023, so no national fee survey exists.
