No. I47 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does I47 sit in the tabular list?

Diseases of the circulatory system (I00-I99), in the block Other forms of heart disease (I30-I5A).

I47

I47 — Paroxysmal tachycardia

Non-billable headerICD-10-CM

I47 is a non-billable header ICD-10-CM code for paroxysmal tachycardia. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

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

Code first

The underlying condition must be sequenced before this code.

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

Other codes that can never be billed with I47

These codes carry an Excludes1 note pointing at I47. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I47 alone.

R00.0Tachycardia, unspecified

Risk adjustment

I47 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

I47 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead I47

4 child codes. Green means billable.
