ICD-10 Code I24.1 – Dressler’s syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I24.1 – Dressler’s syndrome
What it is
I24.1 identifies Dressler’s syndrome, a post-infarction pericarditis syndrome that can occur after myocardial injury. It reflects inflammation of the pericardium following cardiac damage, not routine chest pain or uncomplicated heart attack recovery.
Clinical signs
Typical findings include chest pain that may worsen with breathing or lying flat, pericardial friction rub, and evidence of pericardial inflammation. Clinical features vary; refer to documentation.
When to use this code
Use I24.1 when the provider documents Dressler’s syndrome, post-myocardial infarction pericarditis, or a similar post-cardiac injury inflammatory pericardial syndrome. Code it only when the condition is specifically identified in the record. Check documentation if the note mentions pericarditis without a clear post-infarction link.
Do not use for
Do not use this code for uncomplicated acute myocardial infarction, nonspecific chest pain, or pericarditis without documentation of Dressler’s syndrome. Check documentation for the exact diagnosis.
Coding tip
Match I24.1 only to documented post-infarction pericarditis, and confirm the provider’s wording before assigning the code.
