"These gross prices are listed on spreadsheets called chargemasters, and are typically used as a starting point in negotiations over fees in much the same way the sticker price of a car is the initial bargaining point at an auto dealership. The chargemaster prices are typically negotiated downward to reasonable reimbursement rates for private insurers and public programs such as Medi-Cal and Medicare, according to the suit. Not so for uninsured patients of Sutter hospitals , who are billed the full sticker price, which can be 80 percent higher than the industry standard, according to the suit."
