What the record tells you
C Marcello DDS, MSD, LLC is an NPI registry record for a dental organization at 156 W Main St in Thibodaux, Louisiana 70301. CMS issued NPI 1396481529 on 10 May 2022, and the practice last updated its own entry on 10 May 2022. That was 4 years ago; the details are probably current, but confirm the address when you book.
It is registered under 2 dental taxonomy codes: Orthodontics and dentofacial orthopedics (1223X0400X), Pediatric dentistry (1223P0221X). 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.
Thibodaux holds 8 registered dental practices inside the Houma-Bayou Cane-Thibodaux, LA area, which has 39 in total on the Louisiana side and ranks 8th in the state. 3 of the Thibodaux 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 61.5%, dental clinic or center 17.9%, orthodontics 15.4%. The closest other registered practices are Ellis D. Braud and Fred A. Tenney (0.8 miles, Thibodaux), Acadia Family Dentistry (0.8 miles, Thibodaux) and Roundtree Family Dentistry (1 miles, Thibodaux), with 2 more inside 1.2 miles.
On our figures a routine adult cleaning in Louisiana runs $90 to $135 cash and scaling and root planing $165 to $255 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 (985) 446-3754 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 C Marcello DDS, MSD, LLC.
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.
