I30 — Acute pericarditis

Non-billable headerICD-10-CM

I30 is a non-billable header ICD-10-CM code for acute pericarditis. 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.

Dressler's syndrome (I24.1)
rheumatic pericarditis (acute) (I01.0)
viral pericarditis due to Coxsackie virus (B33.23)

Includes

Conditions this code covers.

acute mediastinopericarditis
acute myopericarditis
acute pericardial effusion
acute pleuropericarditis
acute pneumopericarditis

Other codes that can never be billed with I30

These codes carry an Excludes1 note pointing at I30. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I30 alone.

I01.0Acute rheumatic pericarditis
I31.3Pericardial effusion (noninflammatory)

Risk adjustment

I30 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 to one of these instead I30

4 child codes. Green means billable.
