What Bluebird did
Bluebird chose a cloud PMS, because the growth plan is acquisition and Sam did not want a Windows server in the closet of every office they buy. Before signing, Sam confirmed two things in writing: that the PMS’s data could be exported without a punitive fee, and that its claims pipeline handled the 837D, dental attachments, and real-time eligibility as one workflow, with Bluebird’s Delta member company on the payer list. One experienced dental biller joined as a DSO employee.The three layers
If the distinction is unclear, read Clearinghouse vs RCM vs PMS before choosing a vendor. A product in one layer may not solve a workflow problem that belongs in another.Layer 1: the PMS
The practice management system (PMS) is dentistry’s main system of record. It commonly holds scheduling, clinical charts, imaging integrations, treatment plans, insurance information, charges, and claim status. The market’s first fork is architectural, and for a group with acquisition plans it is the decision that matters:1
Three vendor details are useful before demos. Dentrix Ascend is a separate cloud product from Dentrix, so moving between them requires a conversion rather than a version upgrade.1 Denticon was designed for multi-location groups and uses a multi-tenant architecture.2 Open Dental remains server-based and provides database access, although its license changed from open-source GPL to proprietary at version 24.4.3
Beyond architecture, weigh in order:
- Imaging. Radiographs are both clinical record and claim attachment. Check whether imaging is native, a first-party module, or a third-party bridge, and who owns the images in an export.
- Data export rights. Read the contract. You will want your data for analytics, for a migration, for diligence, and every acquisition you make will need a conversion into this system. Some vendors charge thousands to export what is already yours.
- ERA auto-posting quality. This determines how many hours a week your biller spends on manual posting. Ask for a demo using a real 835 that includes a downgrade.
- Eligibility checking. Integrated 270/271 at scheduling, plus fields to capture what dental verification actually needs: remaining annual maximum, frequency history, downgrade behavior.
- Clearinghouse flexibility. See below.
- Reporting. Days in AR, denial rate, net collection rate, hygiene reappointment rate, and write-off percentage by payer, without exporting to a spreadsheet.
- Pricing model. Per location, per provider, or percentage of collections. Percentage-of-collections pricing from a software vendor deserves scrutiny.
🦷 Orthodontics bills differently: banding date, months of treatment remaining, and contract/installment billing rather than per-visit claims. If ortho is anywhere in your plan, verify the PMS handles ortho contracts before signing; it is a common gap in general-dentistry systems.
Layer 2: the clearinghouse
A clearinghouse translates your claim into the X12 837D format each payer expects, validates it against payer-specific edits, routes it, and brings back acknowledgments (999, 277CA) and remittances (835). See What is a clearinghouse?.The dental test: three transactions, one workflow
A dental clearinghouse earns its keep on three things together, not separately:4- 837D claims, with tooth, surface, and quadrant data intact
- Attachments: radiographs, periodontal charts, and narratives required by the payer for services such as crowns, scaling and root planing, and implants
- Real-time 270/271 eligibility
- Concentration risk. The February 2024 Change Healthcare cyberattack took a huge share of the industry’s claims traffic down for weeks and hit dental practices hard enough that the ADA publicized emergency funding for affected dentists.5 Know your fallback path.
- The 275 roadmap. The 2026 HIPAA attachments rule replaces today’s proprietary NEA-number workflow with the X12 275 transaction, compliance due May 2028. Ask any clearinghouse and PMS vendor how they will carry it before signing a multi-year contract.6 See CDT & the 837D.
Do you even get a choice?
Sometimes not. Many PMSs embed a clearinghouse and make switching hard or impossible. Ask before you sign the PMS contract, because it is much easier to choose a PMS that permits your clearinghouse than to change clearinghouses later. Whatever you pick, verify current payer coverage for your specific payer mix; starting with your Delta member company, against the vendor’s published payer list rather than trusting any headline count. For the full comparison, see The clearinghouses, compared.Layer 3: the people
Three viable shapes at launch:
At one office, the honest general answer is that a competent front desk plus an outsourced service is often cheaper than a full-time hire, but dental billing rewards a specialist earlier than you’d think, because the money leaks through workflows a generalist doesn’t run: benefit verification that captures plan design, attachments sent with the initial claim, predeterminations for major work, and posting that separates denials from downgrades. At Bluebird’s launch volume, one in-house biller was the right call. See In-house billing vs outsourced RCM and Hire your first biller.
Billing staff are DSO employees; billing decisions belong to the PC. The DSO can provide billing support, staff, and systems. It should not be directing what procedure codes get assigned; CDT code selection is clinical judgment, and California’s SB 351, which covers dental practices, explicitly names billing and coding among the functions a management entity may not control.7 Document in the management services agreement (MSA) that coding is the PC’s responsibility, with the DSO providing personnel and systems. See MSA clause anatomy.
Minimum viable stack
To submit one claim you need, at minimum:- A PMS that can produce a charge with current-year CDT codes, tooth/surface/quadrant data, and provider identifiers
- A clearinghouse connection with EDI enrollment complete for your payer
- An attachment workflow live (NEA FastAttach or your clearinghouse’s attachment service)
- ERA delivery configured to that clearinghouse
- One person who knows how to read a 277CA rejection
Your artifact from this step
- Signed PMS contract, with export rights confirmed in writing
- Clearinghouse selected and connected, with submitter ID issued
- Attachment service account live
- EDI enrollment submitted for your first payer
- ERA delivery pointed at the correct receiver
- Billing labor in place, with the coding-responsibility question settled in the MSA
Checklist
- Cloud vs server decided against the growth plan, not the demo
- PMS chosen on imaging, auto-posting, and data portability
- Confirmed whether the PMS permits your choice of clearinghouse, before signing
- Clearinghouse handles 837D + attachments + 270/271 as one workflow
- Payer coverage verified for your actual payer mix, Delta member company first
- Vendor asked for its X12 275 attachments roadmap
- Submitter/receiver IDs issued and recorded
- EDI and ERA enrollment submitted for payer #1
- Billing labor model decided and staffed
- MSA reflects that coding responsibility sits with the PC
