What 93593 covers
This diagnostic catheterization evaluates right-heart hemodynamics in a patient with congenital heart disease and normal native connections. A cardiologist or other qualified physician advances a catheter through the venous circulation into the right heart and pulmonary arteries to assess pressures and related hemodynamic measurements. The service is typically performed in a cardiac catheterization laboratory.
Medicare assigns status C: CMS publishes no national payment, and the local Medicare Administrative Contractor sets payment for each claim. The service has a 0-day global period. Modifier 26 identifies the professional interpretation, modifier TC the technical service, and no modifier represents the global service. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Bilateral reporting is inappropriate; assistant-at-surgery payment requires medical-necessity documentation, and co-surgeons and team surgery are not permitted.
