What Meridian did
Meridian chose a dermatology-capable cloud EHR, connected it to an API-based clearinghouse rather than using the EHR’s default embedded option, and hired one experienced biller as an MSO employee. Alex made the clearinghouse a deliberate decision because Meridian intends to build its own eligibility and denial-analytics tooling, and wanted claim and remittance data available programmatically rather than only through a vendor portal.The three layers
If the distinction between these is fuzzy, read Clearinghouse vs RCM vs EHR before choosing anything. Buying the wrong layer to solve a problem in another layer is the single most expensive mistake in this step.Layer 1: EHR / practice management
The EHR holds the clinical record; the PM side holds demographics, insurance, charges, the patient ledger, and claim status. Most systems for small groups combine them. Choose a system that fits your specialty. Before signing, confirm in writing that you can export your data without a punitive fee, that the system posts 835 remittances automatically, and whether it lets you choose your clearinghouse.🦷 Dental practices use dental practice management systems. Claims are 837D with CDT codes; make sure the clearinghouse handles dental.
🧠 Behavioral health: check how the EHR handles supervision billing and 42 C.F.R. Part 2 confidentiality.
🦴 PT/Chiro: specialty EHRs are built around visit volume and plan-of-care certification tracking, which generic EHRs handle poorly.
Layer 2: the clearinghouse
A clearinghouse translates your claim into the X12 837 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?.Whether you get a choice
Sometimes you do not. Many EHRs embed a clearinghouse and make switching hard or impossible. Ask before you sign the EHR contract, because it is much easier to choose an EHR that permits your clearinghouse than to change clearinghouses later.What matters at this step
If you plan to build your own eligibility, denial, or AR analytics, choose a clearinghouse that exposes eligibility, claims, claim status, acknowledgments, and 835 retrieval over an API. Whatever you pick, verify current payer coverage for your specific payer mix against the vendor’s published network before committing.Layer 3: the people
Three viable shapes at launch:
At Meridian’s launch volume, one in-house biller was the right call, but the general answer is that below roughly two full-time clinicians, an outsourced service is usually cheaper than a competent full-time hire. See In-house billing vs outsourced RCM and Hire your first biller.
Billing staff are MSO employees; billing decisions belong to the PC. The MSO can provide billing support, staff, and systems. It should not be directing what diagnosis or procedure codes get assigned: that is clinical judgment, and California’s SB 351 explicitly names billing and coding among the functions a management entity may not control.1 Document in the MSA that coding is the PC’s responsibility, with the MSO providing personnel and systems. See MSA clause anatomy.
Minimum viable stack
To submit one claim you need, at minimum:- An EHR/PM that can produce a charge with CPT, ICD-10, POS, and provider identifiers
- A clearinghouse connection with EDI enrollment complete for your payer
- ERA delivery configured to that clearinghouse
- One person who knows how to read a 277CA rejection
Your artifact from this step
- Signed EHR contract, with export rights confirmed in writing
- Clearinghouse selected and connected, with submitter ID issued
- 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
- EHR chosen on specialty fit and data portability
- Confirmed whether the EHR permits your choice of clearinghouse, before signing
- Clearinghouse selected; payer coverage verified for your actual payer mix
- 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
