Permanent atrial fibrillation
ICD-10 I48.21 is a billable code used to indicate a diagnosis of permanent atrial fibrillation.
Permanent atrial fibrillation (AF) is a type of arrhythmia characterized by a sustained irregular heartbeat due to disorganized electrical activity in the atria. Clinically, patients may present with symptoms such as palpitations, fatigue, shortness of breath, and an increased risk of thromboembolic events, particularly stroke. The anatomy involved includes the atria of the heart, where the electrical signals that control heartbeats become chaotic. Over time, permanent AF can lead to structural changes in the heart, including atrial dilation and fibrosis, which can exacerbate heart failure and other cardiovascular complications. Diagnosis typically involves an electrocardiogram (ECG) to confirm the presence of AF and may require additional tests such as echocardiography to assess cardiac function and structure. Management strategies often include anticoagulation therapy to prevent stroke, rate control, and rhythm control strategies, which may involve medications or procedures such as catheter ablation. Understanding the progression from paroxysmal to permanent AF is crucial for effective treatment planning.

I48.21 specifically covers permanent atrial fibrillation, which is characterized by a continuous and sustained irregular heartbeat. It is differentiated from paroxysmal and persistent forms of AF, which may resolve spontaneously or require intervention.
I48.21 should be used when the atrial fibrillation is confirmed to be permanent, meaning it has lasted for more than 12 months and is not expected to revert to normal sinus rhythm. This is in contrast to I48.0 for paroxysmal AF or I48.2 for persistent AF.
Documentation should include a clear diagnosis of permanent atrial fibrillation, evidence of ECG findings, and a treatment plan that outlines management strategies such as anticoagulation and rate control. Clinical notes should reflect the chronic nature of the condition.
