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

Mitral Valve

The mitral valve sits between the left atrium and left ventricle, and its two leaflets, chordae tendineae, and annulus must close tightly to keep oxygenated blood moving forward into the aorta rather than backward into the lungs. Repair here typically addresses degenerative prolapse, annular dilation, or ischemic tethering of the leaflets, and surgeons favor conservative reconstruction over replacement whenever the native tissue allows, since preserving the patient's own valve and subvalvular apparatus better protects long-term left ventricular function. Techniques range from leaflet resection and chordal transfer to annuloplasty ring placement, often performed on cardiopulmonary bypass through a median sternotomy or minimally invasive thoracotomy. Documentation should capture the specific defect corrected and whether a ring or band was implanted, since that detail can shift code selection toward a device-bearing value.

Approach: Percutaneous

Percutaneous describes entry by needle or instrument puncture through the skin or mucous membrane to reach the site of the procedure, without cutting the tissue open or using a visualizing scope. It differs from Open in that the site itself is never exposed, and from Percutaneous Endoscopic in that no endoscope is used to see internal structures. Common examples include needle biopsies and injections.

Qualifier: Atrioventricular Valve, Left

This qualifier identifies the left atrioventricular valve, functionally equivalent to the mitral valve, especially in complex congenital anatomy where standard valve names may not apply. It is distinguished from the right atrioventricular valve qualifier by side, and from the common atrioventricular valve qualifier, which applies only when the valve remains undivided.

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.

Commonly Confused With

SupplementSupplement is frequently confused with Repair because both can involve patch material, but Supplement applies when reinforcing material is added to an existing structure without cutting out the abnormal tissue, while Repair implies restoring the structure itself, often by suturing tissue back together.
RestrictionRestriction and Occlusion can also overlap with Repair when a defect is closed, but those terms apply specifically when the objective is narrowing or completely closing a lumen or orifice, which are more precise than the general restoration described by Repair.
