I47

Header — not billable

Paroxysmal tachycardia

The ICD-10 code for paroxysmal tachycardia is I47.

I47 is a non-billable header code. It groups related conditions but cannot be used on its own for reimbursement — select one of the 4 more specific codes below.

Clinical notes

Code first

This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.

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

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

tachycardia NOS (R00.0)
sinoauricular tachycardia NOS (R00.0)
sinus [sinusal] tachycardia NOS (R00.0)

•Confirm the excluded condition(s) listed above are not also present — Excludes1 conditions cannot be coded together with this one.
