Tachycardia ICD-10-CM codes

R00.0 (tachycardia, unspecified) is the code for tachycardia NOS and sinus tachycardia. It is a symptom code from chapter 18 and is not reported when a specific arrhythmia is diagnosed. Inappropriate sinus tachycardia, when stated as such, is I47.11, and paroxysmal sinus tachycardia is I47.19.

Supraventricular tachycardia is I47.10 when unspecified and I47.19 for specified types such as AVNRT, atrial tachycardia, and junctional tachycardia. Ventricular tachycardia is I47.20, with I47.21 for torsades de pointes, I47.22 for CPVT, and I47.29 for other types. I47.9 is paroxysmal tachycardia, unspecified.

Postural orthostatic tachycardia syndrome (POTS) is G90.A. Tachy-brady syndrome is I49.5, and atrial fibrillation with rapid ventricular response is coded to atrial fibrillation, such as I48.91, not to R00.0. Neonatal tachycardia is P29.11.
