A practice billing $1M a year can lose $50,000-$100,000 to claims that were never reworked — and still believe in-house billing is the cheaper option, because nobody ever compares the right numbers.
Most practices compare a biller’s salary to a vendor’s fee and stop there. That’s the wrong math, and it’s why a lot of practices stay stuck with in-house billing that’s quietly costing them more than they think.
What In-House Billing Actually Costs
A full-time biller’s salary is the visible cost. It’s not the real cost.
- Salary + benefits: $45,000-$60,000/year for an experienced biller, more in competitive markets.
- Software and clearinghouse fees: $3,000-$8,000/year, on top of whatever your EHR already charges for billing modules.
- Training and turnover: Billing staff turn over. Every time one leaves, you’re paying for a learning curve on payer rules, your specialty’s coding quirks, and your specific denial patterns — usually 60-90 days before they’re fully productive again.
- The invisible cost — what doesn’t get worked: A single biller covering eligibility checks, coding, submission, payment posting, and denial follow-up cannot do all five well at the same time. Something gets deprioritized, and it’s almost always denial follow-up.
Add it up and a single in-house biller handling everything usually costs $55,000-$70,000/year in direct costs — before counting the revenue lost to claims that never got reworked.
What Outsourced RCM Actually Costs
Most RCM vendors charge a percentage of collections, typically 4-8% depending on specialty and claim volume. On a practice collecting $1M/year, that’s $40,000-$80,000/year.
On paper, that can look similar to or even more expensive than an in-house salary. Here’s where the comparison actually has to go further:
- You’re paying for a team, not a person. Coding, submission, and denial recovery are usually handled by different specialists, not one person juggling all of it.
- The fee scales with performance. A percentage-of-collections model means the vendor only gets paid more if they collect more for you.
- No turnover risk on your end. If a biller leaves a vendor’s team, that’s the vendor’s hiring problem, not a 90-day gap in your revenue cycle.
The Question That Actually Matters
Don’t compare cost. Compare collected revenue net of cost.
If your in-house process is running a 78% clean claim rate and 55 days in A/R, and a vendor can get you to 92% clean claims and 35 days in A/R, the extra revenue collected and collected faster usually covers the fee difference and then some.
When In-House Still Makes Sense
To be fair — if you’re a high-volume practice with the budget for a dedicated billing department, in-house can work well. The math above is about the common case: one or two people trying to cover the entire revenue cycle alone.
