What the record tells you
Seidel and Defilippo Dentistry Partnership is an NPI registry record for a dental organization at 353 York Street in Gettysburg, Pennsylvania 17325. CMS issued NPI 1154631737 on 15 October 2010, and the practice last updated its own entry on 28 October 2014. That was 11 years ago, so treat the phone number and the suite number as unconfirmed until someone answers.
It is registered under 3 dental taxonomy codes: General practice dentistry (1223G0001X), Pediatric dentistry (1223P0221X), Periodontics (1223P0300X). That puts it in 3 categories on this site, led by general dentistry. 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.
Gettysburg holds 11 registered dental practices inside the Gettysburg, PA area, which has 14 in total on the Pennsylvania side and ranks 21st in the state. 4 of the Gettysburg records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 42.9%, dental clinic or center 35.7%, orthodontics 7.1%. The closest other registered practices are Cleveland L. Null, DDS, PC (0 miles, Gettysburg), Adams Oral Surgery INC (0.7 miles, Gettysburg) and Mark P. Rarrick PC (0.9 miles, Gettysburg), with 2 more inside 2.5 miles.
On our figures a routine adult cleaning in Pennsylvania runs $110 to $165 cash and scaling and root planing $180 to $280 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 (717) 334-8193 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. It is not a review, an endorsement or a check on Seidel and Defilippo Dentistry Partnership.
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.
