Questions About I30Overview

What is the ICD-10 code for acute pericarditis?

I30 is the ICD-10-CM category for acute pericarditis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is I30 (Acute pericarditis) a billable code?

No. This is a category header that groups the codes for acute pericarditis, and headers cannot be submitted on claims. Claims for acute pericarditis need a more specific code from this category, such as I30.0, I30.1, and I30.8.

Can I30 be reported with I24.1?

Not as a rule. The Excludes1 note on I30 lists "Dressler's syndrome (I24.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
