A50.56

What This Code Means

This is a bone and cartilage disease that develops in children born with syphilis, occurring years after birth as a late manifestation of the infection passed from mother to child. It causes damage to the bones and joints, particularly affecting the long bones of the legs.

Coding Tips

• •This code requires documentation confirming late congenital syphilis with skeletal involvement; verify the patient's age and maternal syphilis history in the medical record
• •Do not use this code for early congenital syphilis or acquired syphilis; ensure the osteochondropathy is specifically documented as a late manifestation of congenital syphilis
