The layers
Where the confusion comes from
Vendor offerings often overlap: PMSs with embedded clearinghouses. Most dental PMSs bundle an eClaims pathway and present it as a single product. Convenient, and it removes your choice, including your ability to leave. RCM companies that resell clearinghouses. Your dental billing service may route through a clearinghouse you never chose and cannot see. Clearinghouses selling “RCM tools.” Denial analytics, worklists, and dashboards, which look like RCM but are software, not labor. PMS vendors selling “RCM services.” The software vendor also sells you the humans. One throat to choke, and also one vendor holding your data, your pipe, and your operations. “All-in-one” platforms. PMS plus clearinghouse plus billing plus payments plus payroll. See All-in-one platforms and When platforms bundle payroll and card processing for the tradeoffs.Who do I call when X breaks
The most practically useful table on this page.
Two rows deserve emphasis because they are misdiagnosed constantly.
“Denials are rising” is almost never a software problem, and buying a new PMS will not fix it. It is a verification, attachment, documentation, or enrollment process problem.
“Dentist not recognized” is usually an enrollment or linkage problem, not a transaction-format fix. After an acquisition, new location, or hire, confirm the payer-recognized entity, TIN/NPI, contract, location, rendering provider, and effective date. See Set up EDI, ERA, and EFT.
Who codes, and who bills
Many dental practices do not employ dedicated coders. The dentist documents the service and selects or confirms the applicable CDT code, while billing staff handle claim preparation and payer follow-up:
The MSA and operating workflow should allocate coding responsibility in a way that preserves the authority required by state law. California’s SB 351 expressly addresses coding and billing for covered dental practices. Oregon’s SB 951 excludes dental practices from its management-services provisions, so it should not be cited as a dental coding rule.1 A DSO may employ billers, maintain fee schedules, and operate queues where permitted, but it should not determine what a dentist diagnosed or performed. See What a DSO can and can’t do.
Choosing at each layer
PMS. Evaluate multi-location architecture, data-export rights, ERA auto-posting quality, and support for your chosen clearinghouse. See Choose a PMS. Clearinghouse. Evaluate coverage for your payer mix, attachment integration, enrollment support, rejection reporting, and API access if you plan to build internal tools. See The clearinghouses, compared. Labor. A single office may use an outsourced service or share a biller because it cannot support a full-time specialist. A larger group may benefit from centralized in-house billing and the visibility it provides. Compare that value with the staffing burden and any percentage-of-collections pricing. See In-house billing vs outsourced RCM.The bundling question
Buying all layers from one vendor is simpler. It also means:- You cannot swap a weak layer. A great PMS with a poor clearinghouse is a package deal.
- Pricing is opaque. Bundled pricing hides which component costs what.
- Switching costs compound. Leaving means replacing everything at once.
- Your data may not be portable. Read the export terms before signing.
