A52.77

What This Code Means

This code describes syphilis that has spread to the bones and joints, causing inflammation and damage to these structures. It represents a late-stage manifestation of untreated syphilis infection.

Coding Tips

• •Verify documentation specifies bone and/or joint involvement from syphilis; do not use this code for other causes of bone or joint disease
• •This code is typically used for late syphilis (tertiary stage); ensure the stage of syphilis is documented and consider if additional codes for specific bone/joint sites are needed
