CIRCC Cardiac Cath Coding (30+ CPT Codes) – LHC, RHC, Coronary Angiography, Bypass, Hemodynamics | 2025/2026

This highly specialized CPT code reference features 30+ interventional cardiology procedure codes used in CIRCC (Certified Interventional Radiology Cardiovascular Coder) practice, focused on cardiac catheterization and angiographic studies. Updated for 2025/2026, this coding list helps cardiovascular coders, cath lab staff, and coding students correctly assign combinations of left/right heart caths (LHC/RHC), coronary angiography, bypass graft visualization, and hemodynamic studies. Key content includes: LHC and RHC combinations: 93451: RHC only 93452: LHC without coronaries 93453: LHC + RHC 93460: LHC + coronaries + RHC Coronary angiography and bypass graft codes: 93454–93459 for coronaries with or without LHC, bypass grafts 93566–93568 for selective right/left ventricle, aortic, and pulmonary angiography Congenital heart caths & selective injections: +93563, +93564, +93565: Used only with congenital studies +93566, +93567, +93568: Add-on codes for cath injections across ventricles, atria, and pulmonary arteries Advanced cath techniques: 93462: Transseptal or transapical puncture 93463–93464: Pharmacologic agent use and exercise-induced hemodynamic measurements RHC variations: 93530–93533 for alternative LHC access techniques (retrograde, transseptal, pre-existing openings) Perfect for: CIRCC-certified coders and those in training Cardiac cath lab coding specialists Medical coding students focusing on interventional radiology or cardiology Instructors building cath procedure training modules Keywords: CIRCC, cardiac catheterization, LHC, RHC, coronary angiography, bypass grafts, CPT codes, congenital heart cath, hemodynamic study, transseptal puncture, pharmacologic testing, pulmonary angiography, aortography, interventional cardiology coding, cath lab codes
