Estimated using RAND 2024 commercial-to-Medicare ratios. Actual prices vary by insurer, plan, and facility.
How we estimate these prices
These estimates are based on the RAND Hospital Price Transparency Study (4th Edition, 2024). We map each PlainProcedure category onto a RAND CPT-section bucket (Surgery, Radiology, Pathology and Laboratory, Medicine, Anesthesia, Evaluation and Management) or fall back to the national average when no bucket matches. For Laboratory, the applied ratio is 1.85x Medicare (RAND 2024 Pathology and Laboratory bucket (1.85x) + CMS Medicare baseline). Cash/self-pay estimates blend typical cash discounts (55% of billed charges) with Medicare-based estimates (150% of allowed amounts). These are statistical estimates, not quotes. Contact your insurer or provider for actual costs.
