International Classification of Diseases

Last updated: 3/13/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

Paroxysmal atrial fibrillation is a type of irregular heart rhythm where the upper chambers of your heart (atria) beat irregularly and often rapidly. 'Paroxysmal' means this irregular heartbeat comes and goes - it starts suddenly, lasts for a period of time (usually less than 7 days), and then stops on its own, returning to normal rhythm. During episodes, you may feel your heart racing, fluttering, or skipping beats, and you might experience symptoms like shortness of breath, chest discomfort, or fatigue.

Additional Information

This is a specific type of atrial fibrillation that is episodic in nature, as opposed to persistent or chronic forms. It falls under the broader category of heart rhythm disorders.
