Specific code 2014 ICD-9-CM Diagnosis Code 427.41
Ventricular fibrillation
  • Billable Code
  • ICD-9-CM 427.41 will be replaced by an equivalent ICD-10-CM code (or codes) when the United States transitions from ICD-9-CM to ICD-10-CM on October 1, 2015.
  • ICD-9-CM 427.41 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.
Disease Synonyms
  • VENTRICULAR FIBRILLATION
Clinical Information
  • A cardiac rhythm characterized by rapid, usually more than 300 bpm (cycle length: 180 ms or less), grossly irregular ventricular rhythm with marked variability in qrs cycle length, morphology, and amplitude.
  • A disorder characterized by a dysrhythmia without discernible qrs complexes due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricles.
  • 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.
  • An arrhythmia characterized by an irregular pattern of high or low-amplitude waves that cannot be differentiated into qrs complexes or t waves. These electrocardiographic waves occur as a result of fibrillary contractions of the ventricular muscle due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricle.

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 427.41 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
