Is this inaccurate? Email us. Bill items making up each situation are determined from Goodbill's proprietary claims dataset. Insured rates are calculated using median commercial negotiated rates. Uninsured rates are calculated using cash prices.
All prices are calculated using pricing data published by hospitals in machine-readable files per the Hospital Price Transparency Final Rule. Not all hospitals are compliant with this regulation, which results in "Incomplete data". Want to promote compliance? File a complaint.
These are estimates purely for informational purposes and may be different than what you might ultimately be charged. All prices and ratings are subject to change.
