2018/2019 ICD-10-CM Diagnosis Code I49.01
2016 2017 2018 2019 Billable/Specific Code
- I49.01 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
- The 2018/2019 edition of ICD-10-CM I49.01 became effective on October 1, 2018.
- This is the American ICD-10-CM version of I49.01 - other international versions of ICD-10 I49.01 may differ.

that may be applicable to I49.01
ICD-10-CM I49.01 is grouped within Diagnostic Related Group(s) (MS-DRG v36.0):
- 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.
- Arrhythmia characterized by fibrillary contractions of the ventricular muscle due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricle.
