About I47.1

I47.1 is the ICD-10-CM diagnosis code for supraventricular 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 3 subcodes must be used instead.

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

To report this condition, pick the subcode that matches the documentation: I47.10 (unspecified), I47.11 (stated) and I47.19 (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 FY2024 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 427.0 (paroxysmal supraventricular tachycardia).
