Large price discrepancies exist between what private health plans pay for hospital services and what Medicare pays. RAND Corporation researchers used data from three sources — self-insured employers, state-based all-payer claims databases, and health plans — to assess $13 billion in hospital spending in terms of hospital price levels, variation, and trends from 2015 through 2017 in 25 states. In this report, prices reflect the negotiated allowed amount paid per service, including amounts from both the health plan and the patient, with adjustments for the intensity of services provided. These negotiated prices are then compared with Medicare reimbursement rates for the same procedures and facilities to determine relative prices.
This is the first broad-based study that reports prices paid by private health plans to hospitals identified by name and to groups of hospitals under joint ownership (hospital systems) identified by name.
