ICD-10 Code I09.2 – Chronic rheumatic pericarditis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I09.2 – Chronic rheumatic pericarditis
What it is
I09.2 identifies chronic pericardial inflammation due to rheumatic heart disease. Use it when the record describes ongoing or residual pericarditis linked to a rheumatic process.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe persistent pericardial involvement in the setting of rheumatic disease, often alongside other rheumatic cardiac findings.
When to use this code
Use this code when the provider documents chronic rheumatic pericarditis, rheumatic pericardial disease, or chronic pericardial inflammation attributed to rheumatic fever. It may appear with other rheumatic heart disease codes when the chart supports multiple cardiac manifestations. Check documentation if the cause is unclear or only acute pericarditis is described.
Do not use for
Do not use I09.2 for acute pericarditis, nonrheumatic pericarditis, or nonspecific chest pain. If the record does not link the pericarditis to rheumatic disease, check documentation.
Coding tip
Confirm that the note documents both chronic pericarditis and a rheumatic etiology before assigning I09.2.
