Infective pericarditis

This code represents inflammation of the pericardium (the sac surrounding the heart) caused by an infectious agent. This can be bacterial, viral, fungal, or parasitic in origin, leading to symptoms such as chest pain, fever, and shortness of breath.

Assign this code when documentation clearly indicates pericarditis due to an identified or presumed infectious etiology. This includes cases of purulent, viral, or tuberculous pericarditis. Supporting documentation should specify the infectious nature of the pericardial inflammation.

• Differentiate from non-infective forms of pericarditis (e.g., I30.0, I30.8).
• Code the underlying infectious organism (e.g., B95-B97) as an additional diagnosis, if known and documented.
• Ensure documentation specifies "infective" or an infectious cause; otherwise, a non-infective pericarditis code may be more appropriate.
