ICD-10 Code for Tachycardia
The ICD-10-CM code for tachycardia is R00.0 — Tachycardia, unspecified. This is the code the Alphabetic Index gives for tachycardia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
R00.0 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which tachycardia code should you use?
The Alphabetic Index lists 13 codes under Tachycardia. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
By type
| atrial | I47.19 | Other supraventricular tachycardia | |
| auricular | I47.19 | Other supraventricular tachycardia | |

| newborn | P29.11 | Neonatal tachycardia | |
| nodal | I47.19 | Other supraventricular tachycardia | |
| non-paroxysmal AV nodal | I45.89 | Other specified conduction disorders | |
| paroxysmal | I47.9 | Paroxysmal tachycardia, unspecified | |

| sick sinus | I49.5 | Sick sinus syndrome | |
| sinoauricular NOS | R00.0 | Tachycardia, unspecified | |
| sinus [sinusal] NOS | R00.0 | Tachycardia, unspecified | |
| supraventricular | I47.10 | Supraventricular tachycardia, unspecified | |
| ventricular | I47.20 | Ventricular tachycardia, unspecified |
