Operation Definition
Restoring, to the extent possible, a body part to its normal anatomic structure and function
Procedure Overview
Repair is the default root operation for fixing an abnormality of the heart or great vessels when no more specific term - like Replacement, Occlusion, or Restriction - describes what was done. It covers a wide range of interventions, from suturing a traumatic tear in the aorta to closing a congenital defect with the patient's own tissue rather than a device, to correcting an abnormal connection between vessels.
Because Repair is the catch-all category in this body system, it is used for many congenital heart surgeries in children, trauma repairs after chest injury, and corrections of structural problems that don't fit the more specialized definitions elsewhere in the classification. The unifying idea is restoring the anatomy toward its normal form and function using general surgical techniques such as suturing, patching with the patient's own tissue, or reconstructing shape.
Anatomy & Axis Detail
Coronary Artery, Four or More Arteries
This value captures repair of four or more coronary arteries in a single operative encounter, the most extensive tier of the coronary artery count classification. Such extensive multi-vessel repair is uncommon and typically reflects diffuse pathology affecting nearly the entire epicardial coronary tree, as can occur with extensive traumatic disruption, certain vasculitic processes, or widespread iatrogenic injury following complex catheter-based procedures. Each artery may require a different repair strategy, from direct suture to patch angioplasty, depending on the character and extent of the individual lesion, and the surgeon must protect myocardial perfusion across the full territory these vessels supply while working through what is often a technically demanding, prolonged bypass run. Operative documentation should enumerate all vessels repaired so the count of four or more is clearly supported rather than inferred.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Coding & Documentation
Coders should only reach for Repair after ruling out every more specific root operation that fits the documented objective, since ICD-10-PCS convention states a more precise term always takes priority over Repair when both could apply. This makes accurate code assignment dependent on close reading of the operative note for words like "patch," "suture," or "reconstruct" versus terms suggesting occlusion, replacement, or restriction. A common mistake is defaulting to Repair out of convenience when a synthetic patch or device was actually used, which should instead point toward Supplement or Replacement depending on the material and intent.
