ICD-10 Code A52.06 – Other syphilitic heart involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A52.06 – Other syphilitic heart involvement
What it is
A52.06 identifies cardiac involvement caused by syphilis that does not fit a more specific syphilitic heart diagnosis. Use it when the record documents heart disease due to syphilis, but the exact cardiac manifestation is not named.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe syphilitic heart disease as cardiac involvement related to tertiary infection, often with evidence of aortic or other cardiac pathology.
When to use this code
Use this code when the provider documents syphilitic heart involvement and does not specify a more precise cardiac condition. It is appropriate for confirmed cardiac disease attributed to syphilis in the record. If the note only says syphilis without heart involvement, do not assign this code.
Do not use for
Do not use for syphilis without cardiac involvement, or when a different syphilitic heart code is documented. Check documentation if the cardiac diagnosis is unclear or if another cause of heart disease is stated.
Coding tip
Verify that the provider links the heart condition to syphilis before assigning A52.06.
