In-House vs. Outsourced Medical Billing: How to Compare the Real Costs

When practices compare in-house vs outsourced medical billing, the first number on the table is usually a salary. The U.S. Bureau of Labor Statistics puts the median annual wage for medical records specialists at $51,140 as of May 2025. That’s a useful starting point, but it’s only one line of the real cost.

Benefits, software, training, and turnover all add up. So do the claims that don’t get worked when your biller is out, and the hours owners spend reviewing billing at night.

This guide lays out what each option really costs, how outsourced billing is typically priced, and a simple way to compare the two for your own practice.

What in-house medical billing really costs

The true cost of in-house billing includes salary, payroll taxes, and benefits for each biller, plus practice management software, clearinghouse fees, patient statement costs, ongoing training, and coverage when staff are out. Turnover adds recruiting and ramp-up time on top.

Start with what you pay each person on the billing team, then add benefits and payroll taxes. Add the software and clearinghouse costs that exist only because you bill in-house, plus the annual training needed to keep up with code set and payer policy changes.

Don’t forget coverage. When your only biller takes two weeks off, claims either wait or someone else learns the job on the fly. Both have a cost.

How outsourced medical billing pricing works

Most billing companies price full revenue cycle services as a percentage of the collections they bring in. The rate depends on your specialty, claim volume, and which services you include. Some also offer flat fees for specific projects, like credentialing or an A/R cleanup.

A percentage-of-collections model ties the company’s fee to what your practice actually collects, which keeps incentives aligned. When you compare quotes, ask exactly what’s included, such as denial management, patient statements, credentialing, and reporting, so you’re comparing the same scope.

Costs that don’t show up on the budget

Some of the biggest costs of in-house billing never appear as a line item. Denials that nobody has time to appeal, claims that drift past filing deadlines, and patient balances that go unbilled all show up as lower collections instead.

Staffing makes this harder. In Experian Health’s 2025 State of Claims report, providers described a cycle of rising denials and data errors made worse by staffing shortages. When the one person who knows your payers leaves, a lot of that knowledge leaves too.

There’s also the owner’s time. Hours spent reviewing claims, chasing payers, or training new staff are hours not spent with patients or running the practice.

A simple way to compare the two for your practice

Add up your full annual in-house billing cost. Then multiply your annual collections by the outsourced rate you’ve been quoted. Finally, compare how completely each option collects what you’re owed, since a small difference in collections can outweigh a difference in cost.

Use the last 12 months of collections for the outsourced estimate, not a projection. For the collections comparison, look at your denial rate, your A/R past 90 days, and how many denials go unworked today. A billing audit can give you those numbers if you don’t have them handy.

When in-house makes sense, and when outsourcing does

In-house billing can work well for practices with an experienced, stable billing team, steady volume, and simple payer rules. If your team is keeping denials low and A/R current, you may not need to change much.

Outsourcing tends to make sense when billing depends on one or two people, denials and aging A/R are growing, or your specialty has complex coding and authorization rules. Many practices also choose a middle path and outsource only part of the cycle, like denials or credentialing. Our service mix builder shows how that might look.

Questions to ask any billing company before you switch

Ask whether they’ll sign a Business Associate Agreement, what reporting you’ll get each month, whether they have experience with your specialty, who your day-to-day contact will be, how they handle existing A/R, and whether you keep full access to your data.

Under HIPAA, a billing company that handles patient information is a business associate and needs a Business Associate Agreement with your practice. Also ask about contract terms, how you’d leave if it isn’t working, and how they’ll keep claims moving during the transition. A good partner will answer all of this plainly, the way we try to on our about page.

Compare the full picture, not just the salary

The fairest way to weigh in-house vs outsourced medical billing is to compare total cost against total collections. Count everything an in-house team costs, get a clear outsourced quote for the same scope, and look honestly at how much of what payers owe you actually reaches your account today.
