Billable

What This Code Means

A birth defect where the heart has three chambers instead of four because an extra tissue wall divides one of the chambers.

Coding Tips

  • •Cor triatriatum typically affects the left atrium, creating a membrane that divides it into two chambers
  • •Echocardiography findings should be documented to confirm the diagnosis
