427.xx: Which Code(s) Describe AFib With RVR?

Question: What is the correct diagnosis code for atrial fibrillation with rapid ventricular response?

Answer: You should report 427.31 (Atrial fibrillation) for this diagnosis, which you may see documented as Afib with RVR.

Codes 427.41 (Ventricular fibrillation) and 427.42 (Ventricular flutter) are specific to fibrillation and flutter respectively, so you should not use those codes without supporting documentation.
