What This Code Means

A condition where a newborn has abnormally high levels of potassium in their blood, which can affect heart rhythm.

Coding Tips

  • •Document associated findings such as cardiac arrhythmias or EKG changes, and identify underlying causes like renal dysfunction or tissue breakdown
