In-house vs. outsourced billing: the true cost math most practices get wrong

The standard comparison — biller salary versus outsourcing fee — misses most of the real economics. A complete model has five parts, and the two that practices always forget are the ones that dominate.

Part one is fully loaded labor: salary plus benefits, payroll taxes, PTO coverage, software seats, training, and management time. A $52,000 biller costs $70,000+ fully loaded — before you account for hiring costs and the 20%+ annual turnover typical in billing roles.

Part two is technology: clearinghouse fees, statement vendors, eligibility tools, coding references, and reporting software. Individually small, collectively $500–1,500 monthly for a small practice.

Part three — the first forgotten line item — is performance delta. The difference between a 92% and a 97% net collection rate on $2M of annual revenue is $100,000 a year. Whichever option collects better wins the comparison almost regardless of fees.

Part four — the second forgotten line item — is continuity risk. When your one biller resigns, claims stop while you recruit, hire, and train for 3–4 months. The cash flow damage from one transition can exceed a year of outsourcing fees.

Part five is opportunity cost: what your physicians and administrators could do with the hours they spend supervising billing. For owner-operators this is often the largest number in the model.

Run your own numbers honestly and the answer varies by practice — some in-house operations are excellent. But compare complete cost models, not salaries to fees. The two forgotten line items usually decide it.
