Other specified diseases of pericardium

This code represents various uncommon or less precisely defined conditions affecting the pericardium, the sac surrounding the heart, that are not classified under more specific ICD-9 codes. These conditions involve inflammation, fluid accumulation, or structural changes to the pericardium that don't fit into categories like acute pericarditis, chronic constrictive pericarditis, or pericardial effusion of specified etiology.

Use this code when documentation clearly indicates a pericardial disease that doesn't have a more specific ICD-9 code. This might include conditions like idiopathic recurrent pericarditis, certain types of adhesive pericarditis, or other rare or atypical pericardial disorders where the specific cause or presentation is not fully captured by other codes. Ensure the physician's notes explicitly state a diagnosis of "other specified disease of pericardium" or describe a condition that precisely matches this residual category.

• Avoid using this code if a more specific ICD-9 code for pericardial disease exists (e.g., acute pericarditis, pericardial effusion).
• Always review the physician's documentation for precise diagnostic statements to ensure this "other specified" code is appropriate.
• Consider if an underlying systemic disease is causing the pericardial involvement; if so, code the underlying disease first, if applicable, and then this code.
