Valid for Submission
I49.01 is a billable code used to specify a medical diagnosis of ventricular fibrillation. The code is valid for the fiscal year 2021 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).

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
The ICD-10 code I49.01 is grouped in the following groups for version MS-DRG V38.0 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 10/01/2020 through 09/30/2021.
