# Decide: in-house billing vs outsourced RCM
> The cost model for dental billing, the control and visibility tradeoffs, the downgrade-handling question that separates dental RCM vendors, and the contract terms to demand.
For a single dental office, an outsourced revenue-cycle service may cost less than a full-time biller. As the group adds locations, an in-house team can offer more visibility and direct workflow control. Compare both options using your volumes, payer mix, and the dental-specific evaluation question below.
## The cost model
### In-house
| Component | Typical annual |
| -------------------------- | -------------------------------------------- |
| Biller salary | $45,000–$75,000, market-dependent |
| Benefits and payroll taxes | \~20–30% of salary |
| Management time | Real, and usually uncosted |
| Training | CDT manual and update training every January |
| Software seat | Usually included in the PMS |
| **Loaded total** | **\~**$55,000–$**100,000** |
Plus the risks that don't appear in a spreadsheet: turnover, vacation coverage, and single-person dependency.
### Outsourced
Dental-specific RCM vendors are listed in the [RCM directory](/reference/vendors/rcm-directory). Pricing often uses a **percentage of collections**, commonly quoted in the 4–9% range depending on scope and volume. Define "collections" carefully. Patient payments taken at the front desk can make up a large part of dental cash, and including them in the fee base can materially change the effective rate.
| At net collections of | At 6% |
| --------------------- | ----------- |
| \$\$600,000 | \$\$36,000 |
| \$\$1,200,000 | \$\$72,000 |
| \$\$2,400,000 | \$\$144,000 |
In this illustration, the costs cross at roughly $1.0M–$1.5M in net collections, which may represent one busy office or two smaller offices. Use your own compensation, overhead, vendor quote, and collection figures before deciding.
Percentage pricing keeps the cost variable, but the fee can grow faster than the vendor's workload. It may fit an early-stage group and become expensive at higher volume. Ask for lower tiers as collections grow.
## The tradeoffs
| | In-house | Outsourced |
| ------------------------------ | -------------------------------------------------------------- | ----------------------------------------------------------- |
| **Cost at low volume** | High fixed | Low variable |
| **Cost at high volume** | Better | Worse |
| **Visibility** | Full | Depends entirely on reporting |
| **Control over priorities** | Full | Limited |
| **Denial prevention feedback** | Direct because the biller can change the front desk's workflow | Indirect because the vendor does not control your front end |
| **Coverage** | Single point of failure | Team coverage |
| **Dental payer expertise** | You must hire it | Often deeper across payers |
| **Scaling with acquisitions** | Hire again | Automatic |
| **Switching cost** | Rehire | Migration, data retrieval, re-enrollment |
**The prevention gap matters more in dental than in medical.** Most of what looks like a denial problem originates in the front end: benefits verification that missed a frequency limit, a missing tooth clause nobody asked about, an attachment that didn't ride with the crown claim, a predetermination never submitted. An in-house biller can walk to the front desk and change the workflow. An outsourced vendor reports the problem and waits for you to fix it. If your losses are front-end losses, outsourcing the back end treats the symptom.
## The evaluation question: what do you do with a downgrade?
Ask every candidate vendor: **"When a plan pays a posterior composite at the amalgam allowance, what does your team do?"**
The vendor should recognize that a downgrade is not a denial. Where the contract and signed financial consent permit, the difference becomes patient responsibility rather than an appeal or automatic write-off.1 Ask the same question about frequency limits and exhausted annual maximums, then review how the vendor's posting rules code each outcome. A team that cannot explain this distinction may lack dental-specific experience. See [Denials vs downgrades](/concepts/payments/denials-vs-downgrades).
## The hybrid
Frequently the best answer at mid-scale:
* **In-house:** benefits verification against plan design, predeterminations, attachment capture, treatment-plan estimates, and point-of-service collection
* **Outsourced:** insurance AR follow-up, denial management, appeals, and patient statements
You keep control of the processes that prevent problems and buy scale on the ones that resolve them. This is also the natural DSO trajectory: centralize billing in-house as offices accumulate, since the same downgrade posting rules and payer quirks repeat across every location. See [Bill dental claims](/guides/billing/run-the-dental-billing-cycle).
## Contract terms to demand from an RCM vendor
Does the percentage apply to all cash received, or only to what the vendor collected? Does it include patient payments at the front desk? Membership plan revenue? Payments on claims submitted before the engagement started?
Model the fee under each included revenue category because the definition can materially change the effective rate.
State which claim, remittance, AR, and correspondence data the vendor must return, in what format, by what deadline, and at what cost. The transition plan should preserve access to open receivables and payer history.
* Days from charge receipt to claim submission
* Percentage of claims submitted with required attachments on first pass
* Days from denial receipt to first action
* Clean claim rate
* Days in AR, and AR over 90 days
* Reporting cadence and content, with downgrades and benefit-design adjustments separated from true denials
Tie material or repeated misses to a stated remedy, such as a fee reduction, corrective-action plan, or termination right.
Notice period, transition assistance obligations, and no penalty for termination on a missed SLA.
The vendor is a business associate. Ask directly whether PHI is accessed offshore, by whom, and under what controls. See [Put a BAA in place](/guides/agreements/draft-a-baa).
Do not give an RCM vendor independent authority to select CDT codes where state law reserves that judgment to the dentist or professional entity. Recent corporate-practice statutes expressly identify coding among the functions a management entity may not control.2 Document the treating dentist's authority to approve or reject a proposed coding change. See [What a DSO can and can't do](/concepts/model/what-dsos-can-and-cant-do).
Enrollment, credentialing, and PPO fee negotiation should remain yours, or you become dependent on the vendor to change vendors.
## Verify it worked
* [ ] Cost modeled both ways at current and projected volume
* [ ] "Collections" defined precisely in the contract
* [ ] The downgrade question asked and answered correctly
* [ ] Data rights on termination specified
* [ ] SLAs with remedies, including attachment first-pass rate
* [ ] Termination terms acceptable
* [ ] BAA executed; offshore access disclosed
* [ ] Coding responsibility retained by the PC
* [ ] Payer relationships retained by you
* [ ] A reporting pack that separates denials from downgrades
## Common failure modes
| Failure | Consequence |
| -------------------------------------------- | -------------------------------------------- |
| "Collections" undefined | Effective rate materially higher than quoted |
| Vendor appeals downgrades | Appeal capacity wasted on benefit design |
| Vendor writes off downgrades | Patient balances donated, invisibly |
| No data rights on termination | Cannot leave without abandoning AR |
| No SLAs | No basis to hold the vendor accountable |
| Outsourcing to fix front-end losses | Treats the symptom |
| Never renegotiating the rate as volume grows | Overpaying at scale |
| Vendor owns payer relationships | Vendor lock-in |
