Unspecified premature depolarization

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

What This Code Means

This code describes an irregular heartbeat where the heart's electrical system triggers a beat earlier than expected, but the specific type or location of this early beat is not specified. It's a rhythm disturbance that can cause palpitations or other cardiac symptoms.

Coding Tips

  • •Use this code only when the documentation indicates premature depolarization but does not specify whether it's atrial (PAC), ventricular (PVC), or junctional in origin
  • •If the type of premature depolarization is documented (such as premature atrial contractions or premature ventricular contractions), use the more specific codes I49.1 or I49.2 instead
