Mech compl of coronary artery bypass graft, init encntr

This code signifies a mechanical issue, other than infection or hemorrhage, affecting a coronary artery bypass graft (CABG). This could include problems like kinking, obstruction, or displacement of the graft itself. It specifically denotes the initial encounter for this complication.

Use this code when a patient presents with symptoms directly attributable to a mechanical malfunction of their CABG, such as new or worsening angina, dyspnea, or signs of myocardial ischemia, and the cause is determined to be a structural problem with the graft. This applies to the first time the patient is seen for this specific complication.

• Ensure documentation clearly specifies a mechanical complication of the graft, not a disease process like atherosclerosis.
• Verify that this is indeed the initial encounter for this specific complication; subsequent encounters would use the appropriate subsequent encounter code.
• Always code the underlying cause or nature of the mechanical complication if further specified (e.g., kinking, obstruction).
