Superior sinus venosus atrial septal defect

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A birth defect where there is an abnormal opening in the wall between the upper heart chambers located in the upper part of the sinus venosus, the vein that returns blood to the right atrium.

Coding Tips

  • •This is the most common type of sinus venosus ASD; document the superior location to differentiate from inferior sinus venosus defects
  • •Often associated with partial anomalous pulmonary venous return; review documentation for additional cardiac anomalies
