Adenopathy due to secondary syphilis

This code signifies the presence of swollen lymph nodes (adenopathy) that are a direct manifestation of secondary syphilis. Secondary syphilis is a systemic stage of the infection, often characterized by a rash, fever, and generalized lymphadenopathy.

Apply this code when documentation explicitly states adenopathy as a symptom of secondary syphilis. This typically occurs after the primary chancre has healed and the spirochetes have disseminated throughout the body. Supporting documentation would include a positive syphilis serology (e.g., RPR, VDRL, FTA-ABS) and clinical findings consistent with secondary syphilis.

• Always code the underlying infectious disease (syphilis) first, followed by the manifestation.
• Do not use this code for adenopathy due to other causes or for primary/tertiary syphilis.
• Ensure the medical record clearly links the adenopathy to the secondary stage of syphilis.
