Outsourcing Medical Billing: Costs, Benefits, and When It Makes Sense

The visible cost of in-house billing is a salary. The real cost is a stack. A full time biller runs $70,000 to $100,000 per year once salary, payroll taxes, benefits, billing software seats, clearinghouse fees, and training are counted. That stack buys you one person, which means one person's capacity, one person's vacation coverage, and one person's resignation risk.

The larger number hides in the work one person cannot get to. Denials that are never appealed, accounts receivable that quietly ages past timely filing, charges performed but never captured. Counted honestly, in-house billing costs most practices 8 to 14 percent of collections. The percentage a billing company charges replaces the whole stack, not just the salary.

The benefits that hold up in practice are specific. Claims go out daily instead of when the biller catches up, which alone moved one 4 location urgent care network from a 30 to 45 day submission lag to under 24 hours and added $128,000 per month in collections. Denials get worked by people whose entire job is working denials: one behavioral health group recovered $41,000 of a $48,000 payer takeback because every chart got a documented appeal response inside the deadline. And coding gets reviewed by certified coders who read the chart, which is how that same group found 23 percent of its 45 minute sessions had documentation supporting the 60 minute code.

What outsourcing does not fix: bad documentation, missing payer enrollments you never started, or a front desk that skips eligibility checks. An honest billing company tells you which of your problems are billing problems and which are upstream of billing.
