Other syphilitic heart involvement

This code signifies cardiac complications arising from syphilis, excluding syphilitic aneurysm of the aorta. It encompasses various forms of heart involvement due to chronic syphilitic infection, such as syphilitic myocarditis, endocarditis, or valvular disease. These conditions are a manifestation of tertiary syphilis affecting the cardiovascular system.

Use this code when documentation explicitly states "syphilitic heart disease," "syphilitic myocarditis," "syphilitic endocarditis," or other non-aortic cardiac involvement directly attributed to syphilis. This typically occurs in patients with a confirmed history of syphilis, often in its late or latent stages, presenting with cardiac symptoms.

• Do not use this code for syphilitic aneurysm of the aorta; a more specific code exists for that condition.
• Ensure the documentation clearly links the cardiac involvement to syphilis, not just a co-occurrence.
• Sequence this code after the primary diagnosis if the cardiac involvement is a manifestation of an underlying syphilitic infection being treated.
