All-in range = facility cash price + professional (doctor) fee range. “from file” = 10th–90th percentile of the professional rates this hospital posts in its own price file. “ESTIMATE” = no professional rates in the hospital file; range is roughly Medicare’s physician fee for Minnesota up to 3×, not this hospital’s bill. Facility price = hospital-fee rows only (no “professional” billing class, no modifier 26; where a hospital labels every row professional, the technical/global non-26 rate is used). Re-extracted Oct 30, 2026. Anesthesia, pathology, and contrast are not in this table; for colonoscopy see the statewide colonoscopy page, which adds anesthesia (ESTIMATE) and pathology (only if a biopsy is taken, FROM FILE or ESTIMATE). Your actual bill depends on your plan and the physician group — ask for a Good Faith Estimate. How we estimate
