What is a typical contingency fee for outsourced medical billing services?

Contingency pricing aligns vendor incentives with collections, which is why it is the dominant pricing model for outsourced medical billing. The headline rate, however, hides most of what matters. To compare offers honestly, look at four dimensions. First, the rate itself. Vendor pricing typically falls in the 4 to 9 percent of net collections range. High-volume primary care groups with low complexity can sometimes negotiate below 4 percent. Specialty practices (orthopedics, cardiology, oncology, behavioral health, PT, dermatology with procedures) typically pay 6 to 9 percent because specialty-specific coding expertise is more expensive to staff. Very small practices (under $750K in annual collections) often face minimum monthly fees or higher percentages because the vendor cannot achieve economies of scale on their side. Second, scope. A 5 percent rate that includes coding, claim submission, denial management, payment posting, patient statements, patient phone support, and credentialing is not the same as a 4 percent rate that excludes credentialing and patient AR follow-up. Get a written scope of services and confirm which functions are extra. Common excluded items: credentialing and re-credentialing, payer contracting and negotiation, prior authorization, patient collections after 90 days, soft-collection outsourcing, custom reporting, and EHR data integration projects. Third, basis of the percentage. The fee is almost always calculated on net collections (cash actually received), not gross charges, which aligns incentives. Confirm whether refunds, patient credit balances, and government recoupments reduce the base. Fourth, technology requirements. Some vendors require you to switch to their preferred PM system, which introduces switching cost and lock-in. Others integrate with your existing EHR/PM but may charge an interface or data exchange fee. On the practice side, the all-in cost of outsourced billing is the contingency fee plus the cost of internal oversight: someone at the practice has to verify that posted payments match deposits, that denials are actually worked, that patient collections meet expectations, and that the vendor is renegotiating payer contracts where appropriate. Practices that hire a vendor and then ignore the relationship typically discover, 18 months later, that net collection rate has drifted from 96 percent to 90 percent and they have left meaningful money on the table. Treat the vendor as a partner that needs management, not a black box.
