What this is
This is an anesthesia service billed alongside a surgery or procedure. Anesthesia is charged by time and complexity, not as a flat fee.
What affects the price
Because anesthesia is time-based and billed separately from the procedure, it is a common source of surprise charges. Always ask for the anesthesia estimate together with the procedure estimate.
