Stop letting hospitals
overcharge your patients.
Medical bills are the #1 source of consumer billing fraud in America. Upcoding, unbundling, surprise billing, and duplicate charges cost patients billions every year. Warnvo catches them all.
What you're dealing with every day
The billing fraud and overcharge patterns that cost your clients money — and your practice time.
Upcoding
Providers bill for a higher-complexity service than was actually performed. A routine visit coded as a complex ER visit can add $500–$1,500 to a bill.
Unbundling
Procedures that should be billed together are split into separate line items to maximize reimbursement — a practice explicitly prohibited by CMS.
Surprise billing
Patients receive bills from out-of-network providers at in-network facilities. The No Surprises Act (2022) prohibits this in most cases.
Duplicate charges
The same procedure, test, or medication appears multiple times on the same bill — often caught only by a line-by-line review.
Balance billing
In-network providers bill patients for the difference between their charge and the insurance payment — prohibited for most in-network services.
Facility fees
Hospital-owned clinics charge facility fees on top of physician fees — often undisclosed and sometimes illegal under state consumer protection laws.
