BillingBench: the denial management reference for billing professionals

BillingBench is a verified billing intelligence toolkit for medical billing staff, revenue cycle teams, and independent practices. It provides denial code references, verified appeal pathways, prior authorization requirements, payer timely filing deadlines, specialty benchmarks, and financial calculators. Every policy claim cites a primary source with a verification date.

The toolkit is built and maintained by an MD candidate, MS, MPH, so the denial logic and appeal arguments reflect the clinical rationale behind each procedure, not only the billing code. Tools include the denial code reference, Appeal Builder, timely filing calculator, 835 ERA parser, interest calculator, and payer intelligence and specialty guides.
