I47.20 is a billable diagnosis code used to specify a medical diagnosis of ventricular tachycardia, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like I47.20 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

EKG ventricular tachycardia monomorphic
EKG ventricular tachycardia polymorphic
EKG: ventricular tachycardia
EKG: ventricular tachycardia
Familial ventricular tachycardia
Fascicular ventricular tachycardia

Idiopathic fascicular ventricular tachycardia
Idiopathic ventricular tachycardia
Incessant infant ventricular tachycardia
Induced ventricular tachycardia
Left outflow tract ventricular tachycardia
Narrow QRS ventricular tachycardia
Nonsustained paroxysmal ventricular tachycardia
Nonsustained ventricular tachycardia
Paroxysmal ventricular tachycardia
Pulseless ventricular tachycardia
Recurrent ventricular tachycardia
Right ventricular outflow tract ventricular tachycardia
Sustained ventricular tachycardia

Ventricular tachycardia with normal heart
Ventricular tachycardia, monomorphic
Ventricular tachycardia, polymorphic
Ventricular tachycardia, polymorphic without Q-T prolongation
Wide QRS ventricular tachycardia

CCSR Category Code: CIR017
Inpatient Default CCSR: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

I47.20 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
308	CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH MCC	05	1.2022
309	CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITH CC	05	0.7447
310	CARDIAC ARRHYTHMIA AND CONDUCTION DISORDERS WITHOUT CC/MCC	05	0.553

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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
