About I47.2

I47.2 is the ICD-10-CM diagnosis code for ventricular tachycardia. It belongs to category I47 (paroxysmal tachycardia), block I30-I5A (other forms of heart disease) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within I47 (paroxysmal tachycardia), I47.2 is specifically for ventricular tachycardia. Related codes cover Re-entry ventricular arrhythmia (I47.0), supraventricular tachycardia (I47.1) and unspecified (I47.9).

To report this condition, pick the subcode that matches the documentation: I47.20 (unspecified), I47.21 (pointes), I47.22 ([CPVT]) and I47.29 (tachycardia).

Code first tachycardia complicating: abortion or ectopic or molar pregnancy (O00-O07, O08.8) and obstetric surgery and procedures (O75.4).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2023 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 427.1 (paroxysmal ventricular tachycardia).
