Code Description

ICD-10 A52.00 is a billable code used to indicate a diagnosis of cardiovascular syphilis, unspecified.

Key Diagnostic Point:

Cardiovascular syphilis is a late manifestation of syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum. This condition can lead to serious cardiovascular complications, including aortitis, aortic regurgitation, and coronary artery disease. The unspecified designation indicates that the specific cardiovascular manifestations are not detailed in the medical record. Patients may present with symptoms such as chest pain, heart murmurs, or signs of heart failure. Diagnosis typically involves serological testing for syphilis, including non-treponemal tests (e.g., RPR, VDRL) and treponemal tests (e.g., FTA-ABS). Treatment usually involves the administration of benzathine penicillin G, which is effective in eradicating the infection and preventing further complications. Regular follow-up and monitoring are essential to assess treatment efficacy and manage any cardiovascular sequelae. Contact tracing is crucial for preventing further transmission of syphilis, as it is highly contagious and can lead to severe health outcomes if left untreated.
