Leakage of coronary artery bypass graft, initial encounter

This code signifies the escape of blood or fluid from a coronary artery bypass graft (CABG) during the initial period of treatment. This leakage indicates a failure or complication of the surgical connection, potentially leading to bleeding or insufficient blood flow through the graft.

Use this code when a patient presents with signs or symptoms of a leaking CABG, such as hematoma, active bleeding, or hemodynamic instability, and it is the first time this specific complication is being addressed. This applies to the immediate post-operative period or during the initial hospitalization for the complication.

• Ensure documentation clearly specifies "leakage" of the graft, not just general bleeding.
• Confirm this is the "initial encounter" for the treatment of this specific leakage. Subsequent encounters would use a different seventh character.
• Always code the underlying reason for the CABG (e.g., coronary artery disease) as a secondary diagnosis.
