Secondary syphilitic female pelvic disease

This code signifies inflammatory conditions of the female pelvic organs, such as salpingitis, oophoritis, or pelvic peritonitis, that are a direct manifestation of secondary syphilis. It indicates that the pelvic disease is a systemic complication of the spirochete infection, not a primary gynecological issue.

Apply this code when documentation clearly links a diagnosis of female pelvic inflammatory disease (PID) to a confirmed secondary syphilis infection. This typically occurs during the disseminated stage of syphilis, following the primary chancre. Documentation should specify both the pelvic disease and the syphilitic etiology.

• Always sequence the syphilis code (A51.-) first, followed by this code, to indicate the underlying systemic infection.
• Distinguish from other causes of PID (e.g., N70.-) where syphilis is not the causative agent.
• Ensure the medical record explicitly states "secondary syphilis" as the cause of the pelvic disease.
