Atrial premature depolarization

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

What This Code Means

Atrial premature depolarization is a condition where the heart's upper chambers (atria) beat earlier than expected, causing an irregular heartbeat. This extra heartbeat occurs before the normal heartbeat should happen.

Coding Tips

  • •Verify documentation specifies atrial origin (not ventricular) to distinguish from V.P.C.s; atrial premature depolarizations are also called PACs or APCs
  • •Do not assign this code if the condition is secondary to another documented arrhythmia or acute cardiac event; code the primary condition instead
