A52.09

What This Code Means

This code describes syphilis that affects the heart and blood vessels in ways other than the more common forms like aortic aneurysm or aortic regurgitation. It represents late-stage syphilis complications involving the cardiovascular system.

Coding Tips

• •Verify the specific cardiovascular manifestation in the medical record (such as myocarditis, pericarditis, or coronary artery involvement) to ensure A52.09 is the most appropriate code rather than a more specific cardiovascular syphilis code
• •Confirm the stage of syphilis (late/tertiary) is documented, as cardiovascular involvement typically occurs in late syphilis; coordinate with the primary syphilis diagnosis code if applicable
