A clearinghouse translates, validates, and routes claims, then returns claim responses and remittances. Dental workflows often combine an 837D with radiographs, periodontal charts, or narratives and a preceding real-time eligibility check. Evaluate how well each vendor connects those parts of the workflow.

​
Prerequisites

  • Your actual payer mix, including any Medicaid dental benefit administrators
  • Your entity count now and in three years
  • Confirmation from your PMS vendor that you may choose your own clearinghouse; see Choose a PMS

​
The dental buying criteria

Three transactions have to work together, and the test is whether they are one workflow or three products:

​
The vendor landscape

Dental-focused networks. DentalXChange, legally EDI Health Group, Inc., runs ClaimConnect. It combines 837D submission with validation, an integrated attachment service, real-time eligibility, claim status, and ERA.1 Vyne Dental brings together NEA, the FastAttach attachment repository; Renaissance/Tesia, a clearinghouse; and Onederful, an eligibility API. It offers claims, attachments, and real-time 270/271 through one connection and reports serving more than 100,000 dental providers. That figure is vendor-reported.2 Broader networks that also carry dental. Legacy Change Healthcare dental products now sit inside Optum, whose network supports the 837D alongside medical transactions.3 Availity also carries the 837D, and some Blues plans require dental submission through it. Its attachment workflow is separate from claim submission.4 The practical split: dental-native vendors sell the bundle; medical-first networks sell reach. A dental group usually wants the bundle, and adds a medical-capable path only for medical billing of dental work. The full comparison is in the clearinghouse comparison.

​
Ask every vendor about their 275 roadmap

Today’s attachment workflow is proprietary. You upload files to NEA FastAttach or the clearinghouse’s service, then place the reference number on the claim. In March 2026, CMS finalized X12 275 as the HIPAA claims-attachment transaction, with a compliance date of May 26, 2028.5 Before signing a multi-year contract, ask how the vendor will support 275, whether that support will cost extra, and what happens to stored attachments. See CDT and the 837D and dental attachments for background.

Steps

1

Confirm your PMS permits your choice, in writing

2

List your top 20 payers by expected volume

Include your state’s Medicaid dental benefit administrator, such as DentaQuest, MCNA, Liberty, or another contractor. Verify whether claims route through the clearinghouse or the administrator’s portal.
3

Check each payer against candidates' published lists, by name

Evaluate coverage by transaction rather than total payer count. A payer may accept claims while offering no 271 or ERA connection through that clearinghouse.
4

Test the claim-plus-attachment workflow end to end

One test claim, one radiograph, one narrative. If it takes three logins, it will take three logins ten thousand times a year.
5

Ask each candidate who handles EDI/ERA/EFT enrollment and how long it takes

6

Ask for the X12 275 roadmap

7

Test multi-entity submitter configuration

8

Request the SOC 2 report and ask about incident history

9

Compare total cost including per-claim, per-attachment, eligibility, enrollment, and minimums

Attachment and eligibility transactions are often priced separately from claims. Model the cost using your actual volumes.

​
Concentration risk

The February 2024 Change Healthcare cyberattack stopped claim submission and remittance across the network for weeks, and hit dental practices hard enough that the ADA publicized emergency funding for affected dentists.6 It is the standing lesson in single-clearinghouse dependency. Whatever you choose:
  • Hold cash reserves sized to survive several weeks with no insurance collections. This is the only mitigation that works regardless of cause.
  • Document a fallback. Identify which payers accept direct portal submission and whether you could stand up a second clearinghouse.
  • Keep your data portable, so you can move.
See What is a clearinghouse?.
