In the Alphabetic Index, the different types of atrial fibrillation all appear at the same indentation level under “Fibrillation, atrial.” If a provider documents various types of atrial fibrillation, such as chronic, persistent, and permanent, would separate codes be assigned for each type of atrial fibrillation?
Assign only one code for the specific type of atrial fibrillation (AF), since some of the terms are less specific, such as chronic AF, and some of the different types of AF cannot clinically occur at the same time. For example, if the provider documents both chronic and persistent AF, assign only code I48.1, Persistent atrial fibrillation. Persistent atrial fibrillation typically may require repeat pharmacological or electrical cardioversion and does not stop within seven days. Longstanding persistent atrial fibrillation is persistent and continuous lasting longer than one year. Permanent atrial fibrillation is longstanding persistent atrial fibrillation where cardioversion is not indicated or cannot be performed.
