Medicare rate (2026)$278.89 — Medicare’s published national payment rate for this procedure (CMS Hospital Outpatient Prospective Payment System).

Insurance-negotiated range$24.83 – $382 — the lowest and highest rates this hospital has negotiated with insurance plans for this procedure, as published in its file.
