What this is
This is a surgical or procedural code. The published price typically covers the facility/procedure charge for performing it — the operating-room, equipment, and staff resources.
What affects the price
A surgical price almost never includes the separate bills you may receive from the surgeon, anesthesiologist, or pathologist. Ask the hospital for a bundled good-faith estimate that lists every expected charge, not just this one.
