ICD-10 Code I31.2 – Hemopericardium, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I31.2 – Hemopericardium, not elsewhere classified
What it is
I31.2 identifies blood in the pericardial sac, the space around the heart, when it is not classified elsewhere. Use it when documentation clearly states hemopericardium.
Clinical signs
Clinical features vary; refer to documentation. Findings may include pericardial effusion with evidence of blood, often confirmed by imaging, procedure results, or operative notes.
When to use this code
Use I31.2 when the provider documents hemopericardium as the diagnosis and no more specific cause or category is assigned. It may appear after trauma, procedures, or other cardiac conditions, but you should code only what is documented.
If the record describes pericardial bleeding without a clearer alternate code, this code may fit. Check documentation for the underlying cause and any additional required codes.
Do not use for
Do not use this code for simple pericardial effusion without blood, or when another specific diagnosis better describes the condition. Do not assume hemopericardium without documentation.
Coding tip
Verify the source note or procedure report for explicit mention of blood in the pericardial space before assigning I31.2.
