Ask Dr. Z

How would you code this since 93566 and 93567 are add-on codes? "Procedure: The patient was brought to the hybrid catheterization laboratory from the PCICU on ECMO support. The chest was sterilely prepped and draped, the silastic skin patch was removed, and the chest was explored. A 5 French sheath was directly inserted in the RV through a purse string. A 5 French Berman was advanced via the sheath to the RVOT and AAO, and angiograms were performed. The catheter and sheath were removed, then proceeded with repeat surgery to address the RVOT obstruction. Angiograms 1. AAO-the aortic arch is patent, there is no recurrent coarctation 2,3. RV-there is severe narrowing just below the aortic valve."
