33315 vs 33310

Date: Feb 8, 2023

Question:

This pt had a CAGB 33533 and thru a separate incision, had a thrombus removed from the LT atrial appendage. The physician billed 33315. I was just wondering if 33310 is more appropriate because with 33315 aren’t we charging for CPB twice? Here is the op note portion of 33315: I began the operation by lifting the heart, exposing the left atrial appendage. This was opened. The clot was removed and passed off the table as a specimen. The opening was oversewn with a 5-0 Prolene suture in 2 layers.

Thank you.
