Breakdown (mechanical) of coronary artery bypass graft, subs

This code signifies a mechanical failure or malfunction of a coronary artery bypass graft (CABG) that has been previously implanted. This breakdown is not due to a biological process like restenosis, but rather a structural issue with the graft itself. The patient is currently receiving routine care during the healing or recovery phase of the initial treatment for the breakdown.

Use this code when a patient presents for follow-up care, such as an office visit or hospital readmission, after an initial intervention to address a mechanical breakdown of their CABG. This applies to situations like a dislodged, fractured, or kinked graft, where the patient is no longer in the acute phase of treatment for the breakdown.

• Ensure the documentation clearly specifies a mechanical breakdown, not a biological complication.
• Confirm the encounter is for subsequent care, meaning the initial treatment for the breakdown has already occurred.
• Distinguish from initial encounter (A) or sequela (S) codes for the same condition.
