athenahealth RCM vs an Outsourced Billing Service
Should billing come from the EHR vendor or from an independent billing company?
Short answer
This is not really a comparison of two billing companies. It is a comparison of two structures, and the structural difference matters more than any feature list.
In the platform model, the same vendor supplies the software your clinicians document in and the service that collects your money. Data moves between them without an interface, and there is one contract and one number to call.
In the independent model, billing is a service layered onto the practice management system you already run. You manage two relationships instead of one, and you gain the ability to change either without disturbing the other.
Which is better depends almost entirely on one question: how confident are you that you want the same vendor for the next decade?
Side by side
Platform RCM (EHR vendor) vs Independent billing service
| Dimension | Platform RCM (EHR vendor) | Independent billing service |
|---|---|---|
| What you are buying | EHR, practice management and RCM as one product | Billing and revenue cycle only, on your existing system |
| Clinical software | Typically the vendor's own EHR; confirm whether RCM is available separately | Whatever you already run; unchanged |
| Data integration | Native — no interface between chart and claim | Works within your PM system; no new interface, but two vendors |
| Vendor relationships | One | Two — your PM/EHR and your biller |
| Cost of changing billers | Higher where billing is coupled to the platform contract | Moderate — notice period, clinical systems untouched |
| Cost of changing EHR | High — billing moves with it | Independent of billing |
| Pricing model | Typically a percentage of collections; confirm current terms directly | Percentage of net collections, 3–6% at Vizora |
| Payer rules and edits | Large national rules engine, a genuine strength of scale | Payer-specific and NCCI edits, plus regional payer knowledge |
| Specialty coding depth | Broad; depth varies by specialty | Specialty-assigned certified coders |
| Denial appeal capacity | Scales with the platform | Scales with the service; ask for appeal rate, not denial rate |
| Best-fit practice size | Varies by vendor and tier; confirm fit for your size | Solo through mid-size groups |
| Implementation burden | Significant — a platform migration touches clinical workflow | Lower — billing changes, clinical workflow does not |
Choose platform RCM when
- You are replacing your EHR anyway, so the migration cost is already being paid.
- You want a single vendor accountable end to end, and you value that more than the ability to change one piece.
- You are a larger group with the administrative capacity to run a platform implementation properly.
- Native chart-to-claim data flow matters more to you than system independence.
Choose an independent billing service when
- Your clinicians are productive in your current EHR and you do not want to retrain them to fix a billing problem.
- You want billing performance to be contestable — if it underperforms, you can change it without a clinical migration.
- You bill a specialty where coding depth matters more than platform breadth.
- You want to solve collections now rather than after a multi-month platform implementation.
When this is not the right answer
If you are already committed to a platform and happy with the clinical side, moving billing out is often not worth the friction — the integration you would give up is real. And a large platform's payer rules engine is a genuine advantage of scale that an independent service matches through specialisation rather than volume. The case for an independent biller is strongest when your clinical systems are fine and only collections are failing.
Questions
Generally yes — an independent biller can work inside most practice management systems given appropriate user access, and the Business Associate Agreement governs how they handle protected health information. What you should confirm before signing is the specific access level your biller needs and whether your platform contract restricts third-party billing. Ask both vendors directly rather than assuming.
Not reliably, and the rate is the wrong comparison. What determines cost is net collection rate: a two-point difference on $2 million in charges is $40,000, which is larger than most differences in billing rate. Compare vendors on first-pass denial rate, days in AR and appeal rate — and insist on those numbers before you compare percentages.
Under a platform model, billing usually moves with the EHR, because the service is built on that software. Under an independent model it does not — the biller works in whatever system you run, so a clinical migration and a billing relationship are separate decisions. That separation is the main structural argument for an independent service.
