What the record tells you
Michael Bernfeld DDS Michael Korngold DDS is an NPI registry record for a dental organization at 1801 Avenue M in Brooklyn, New York 11230. CMS issued NPI 1205972650 on 30 January 2007, 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 5 dental taxonomy codes: Dentist (122300000X), Endodontics (1223E0200X), Periodontics (1223P0300X), Prosthodontics (1223P0700X), Oral and maxillofacial surgery (1223S0112X). That puts it in 5 categories on this site, led by oral and maxillofacial surgery. 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. One further NPI is registered to what looks like the same business at this address (Bernfeld & Korngold, NPI 1336470061); it is covered by this page rather than given a page of their own.
Brooklyn holds 767 registered dental practices inside the New York-Newark-Jersey City, NY-NJ area, which has 4,603 in total on the New York side and ranks 1st in the state. 42 of the Brooklyn records also register oral and maxillofacial surgery, so this is one of several local options in that category. Across the metro the mix runs general dentistry 65.9%, dental clinic or center 14.6%, orthodontics 7.5%. The closest other registered practices are Maks Dental PLLC (0.1 miles, Brooklyn), Mery Max Dental PLLC (0.1 miles, Brooklyn) and Advanced Family Dentistry PC (0.1 miles, Brooklyn), with 2 more inside 0.2 miles.
On our figures a routine adult cleaning in New York runs $150 to $250 cash and scaling and root planing $225 to $370 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 (718) 252-8989 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.
CMS NPPES NPI data file, August 2026, snapshot 10 August 2026. US federal public data (FOIA-disclosable, no charge). CMS NPI files. 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. It is not a review, an endorsement or a check on Michael Bernfeld DDS Michael Korngold DDS.
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.
