Store description excerpt
A long-term place for every hospital and outpatient charge you may have to prove later. A $4,500 emergency-room estimate becomes a $28,000 hospital bill three weeks after discharge. An out-of-network anesthesiologist independently bills $3,200 from a surgery the patient was told was in-network. The same lab panel appears on three statements. CPT 99284 is upcoded to 99285, a $400 swing the patient never sees. BillWitness is built for the 145 million Americans who receive medical bills every year: high-deductible plan members, chronic-illness households, families digging out from a hospitalization, and patients navigating the No Surprises Act. They all need the same thing: a structured, on-device place to put every line that crosses the kitchen table, and a way to reach for it years from now. How BillWitness handles a bill Every charge anchors to a provider, identified by NPI, and tracks across years. Hospitals, physician groups, anesthesia, pathology, radiology, ER physicians, specialists, each becomes a row in the long-term audit. Each itemized line (CPT or HCPCS code, quantity, modifiers, charge) is logged and screened against eight common error patterns: duplicate, upcoding, unbundling, phantom, wrong CPT, quantity error, wrong provider, wrong insurance. Bill, EOB, and patient-payment reconcile three ways. Six discrepancy categories are flagged automatically. Surprise-bill protections under the No Surprises Act are tracked via an IDR module with a 120-day countdown and the open-negotiation clock. Where your records live Open the app and start. No account.
