Syphilitic endocarditis

This code represents inflammation of the inner lining of the heart, specifically the heart valves, caused by a Treponema pallidum infection (syphilis). It is a manifestation of tertiary syphilis, occurring years after the initial infection. The condition can lead to significant valvular damage and heart failure.

Use this code when documentation clearly indicates endocarditis as a direct result of syphilis. This typically involves a positive syphilis serology (e.g., RPR, VDRL, FTA-ABS) in conjunction with echocardiographic evidence of endocarditis and clinical signs of cardiac involvement. Documentation should specify the syphilitic etiology.

• Ensure the documentation explicitly links the endocarditis to syphilis; "endocarditis due to syphilis" or "syphilitic endocarditis" is ideal.
• Do not confuse with other forms of endocarditis (e.g., bacterial, fungal) unless syphilis is also confirmed as the causative agent.
• Code also for the specific type of heart failure or valvular disease if present and documented as a consequence.
