About coding hemopericardium

The ICD-10-CM code for hemopericardium is I31.2 (Hemopericardium, not elsewhere classified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I31.2.

Within I31 (other diseases of pericardium), I31.2 is specifically for hemopericardium, not elsewhere classified. Related codes cover chronic adhesive pericarditis (I31.0), chronic constrictive pericarditis (I31.1), pericardial effusion (noninflammatory) (I31.3), cardiac tamponade (I31.4), other specified diseases of pericardium (I31.8) and disease of pericardium, unspecified (I31.9).

Don't report I31.2 together with the conditions in its Excludes1 note: hemopericardium as current complication following acute myocardial infarction (I23.0) and malignant pericardial effusion (I31.31).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

Don't confuse with (Excludes1 for I31.2)

  • hemopericardium as current complication following acute myocardial infarction (I23.0)
