Pericarditis in diseases classified elsewhere (I32) ICD-10-CM
The I32 code range covers pericarditis in diseases classified elsewhere with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- underlying disease
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the I32 Code Range
The ICD-10 code I32 is used to classify cases of pericarditis that occur as part of other diseases rather than as isolated conditions. This code captures pericarditis related to a variety of underlying causes, making it essential for accurately coding secondary pericardial inflammation.
Pericarditis in diseases classified elsewhere (I32) covers inflammation of the pericardium linked to specific conditions such as familial Mediterranean fever, post-cardiac injury syndrome, various forms of histoplasmosis (including Histoplasma capsulatum and Histoplasma duboisii infections), uremia-related pericarditis, and complications from trauma or chronic diseases like myxedema and severe anemia. Common synonyms like post-traumatic pericarditis and acute or chronic pericarditis secondary to systemic illnesses clarify that this code is appropriate when the pericardial inflammation is a consequence of another disease process. For medical coders and healthcare providers, knowing the ICD-10 code for pericarditis due to other illnesses ensures proper documentation and helps distinguish these cases from primary pericarditis, aiding in precise clinical classification and billing accuracy.
