Most comparisons of in-house versus outsourced billing are written by outsourced billing companies. So take this one with appropriate salt — and check the math yourself.
Let's use a concrete example: a 4-provider practice collecting roughly $300,000 per month ($3.6M/year).
The in-house cost most people calculate
- 2 billing staff at $48,000 salary = $96,000
- 1 billing manager at $65,000 = $65,000
Total: $161,000/year. That's the number most practices have in their head.
The costs that don't make the spreadsheet
- Benefits and payroll tax — typically 25–30% on top of salary: +$45,000
- Billing software / clearinghouse fees: +$6,000–12,000
- Training and continuing education (codes change annually): +$3,000
- Turnover — billing has high churn. Recruiting + 3 months of reduced productivity per departure: +$15,000–20,000 amortized
- Coverage gaps — when your biller takes vacation or quits, claims stop going out. This one is rarely quantified and is often the most expensive.
- Management time — someone has to supervise them. Usually a physician or practice manager whose time is worth more.
Realistic fully-loaded in-house cost: $230,000–$245,000/year.
The outsourced cost
Performance-based billing typically runs 4–7% of collections. On $3.6M, that's $144,000–$252,000/year.
So the real question is performance
If both options cost roughly the same, the question becomes: which one collects more?
Where the difference actually shows up
Clean claim rate. In-house typically runs 70–85%. A well-run outsourced operation runs 95%+. On $3.6M in charges, moving from 80% to 98% clean is worth far more than the entire billing budget.
Coverage. An outsourced team doesn't take a vacation. Claims go out every day.
Denial follow-through. In-house staff run out of hours and denials get written off. That's the silent leak.
When in-house genuinely wins
I'll be honest about this, because it's true:
- If you have an exceptional billing manager who's been with you for years and knows your payers cold — keep them. That person is worth more than any vendor.
- If you're a very small practice (1 provider, low volume), percentage-based pricing may cost more than a part-time biller.
- If you require physical, in-person control over every process for reasons specific to your practice.
When outsourcing wins
- Your clean claim rate is below 90%
- Your days in AR are above 40
- You've lost a biller in the last 18 months
- Nobody in your practice can tell you your top denial reason this month
That last one is the tell. If you don't know your top denial reason, nobody is managing your revenue cycle — they're just processing claims.
