2022 ICD-10-CM Code I49.01
Ventricular fibrillation
Code Classification
I49.01 is a billable diagnosis code used to specify a medical diagnosis of ventricular fibrillation. The code I49.01 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I49.01 might also be used to specify conditions or terms like idiopathic ventricular fibrillation not brugada type, paroxysmal familial ventricular fibrillation, sustained ventricular fibrillation, ventricular fibrillation, ventricular fibrillation and flutter , ventricular flutter, etc.
The code is commonly used in cardiology medical specialties to specify clinical concepts such as cardiac arrhythmias (other).

Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Idiopathic ventricular fibrillation not Brugada type
- Paroxysmal familial ventricular fibrillation

- Ventricular fibrillation
- Ventricular fibrillation and flutter
- Ventricular flutter
Clinical Information
- VENTRICULAR FIBRILLATION-. a potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses 400 600/min in heart ventricles. such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness syncope. it is one of the major electrocardiographic patterns seen with cardiac arrest.
- ROMANO WARD SYNDROME-. a form of long qt syndrome that is without congenital deafness. it is caused by mutation of the kcnq1 gene which encodes a protein in the voltage gated potassium channel.
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code I49.01 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 308 | CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH MCC | 05 | 1.1993 |
| 309 | CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH CC | 05 | 0.7494 |
| 310 | CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITHOUT CC/MCC | 05 | 0.5584 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Information for Patients
Arrhythmia
An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.
Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.
Symptoms of arrhythmias include
- Fast or slow heart beat
- Skipping beats
- Lightheadedness or dizziness
- Chest pain
- Shortness of breath
- Sweating
Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.
