SVT ICD-10 Code: I47.1
Last updated: January 4, 2026
The ICD-10 code for SVT (supraventricular tachycardia) is I47.1. This includes paroxysmal SVT, AVNRT, AVRT, and atrial tachycardia.
SVT and Related Arrhythmia Codes
| Code | Description | Use When |
|---|---|---|
| I47.1 | Supraventricular tachycardia | SVT, PSVT, AVNRT, AVRT |
| I47.10 | Supraventricular tachycardia, unspecified | Type not specified |
| I47.11 | Inappropriate sinus tachycardia | IST documented |
| I47.19 | Other supraventricular tachycardia | Other specified SVT |
| I47.2 | Ventricular tachycardia | VT (different from SVT) |
| I48.0 | Paroxysmal atrial fibrillation | Afib (not SVT) |
Terminology Mapping
| Clinical Term | ICD-10 Code |
|---|---|
| SVT | I47.1x |
| PSVT (Paroxysmal SVT) | I47.1x |
| AVNRT | I47.1x |
| AVRT | I47.1x |
| Atrial tachycardia | I47.1x |
| WPW with SVT | I45.6 + I47.1x |
| NSVT | I47.2 (ventricular, not SVT) |
Coding Tips
- SVT vs VT: SVT is I47.1, VT is I47.2. Verify documentation
- Paroxysmal SVT: Code as I47.1x (paroxysmal is implied)
- WPW syndrome: Add I45.6 if WPW is underlying cause
- NSVT ≠ SVT: NSVT is non-sustained VT (I47.2), not supraventricular

Frequently Asked Questions
What is the ICD-10 code for SVT?
I47.1 (Supraventricular tachycardia) is the ICD-10 code for SVT. This includes PSVT, AVNRT, AVRT, and atrial tachycardia.
What's the difference between SVT and VT codes?
SVT (supraventricular tachycardia) is I47.1. VT (ventricular tachycardia) is I47.2. The origin of the arrhythmia determines the code.
How do I code SVT with WPW syndrome?
Code both I45.6 (Pre-excitation syndrome/WPW) and I47.1 (Supraventricular tachycardia). The WPW code captures the underlying substrate.
