Bone and joint lesions due to yaws

This code describes bone and joint manifestations resulting from yaws, a chronic tropical infection caused by the bacterium Treponema pallidum pertenue. These lesions can include periostitis, osteitis, and dactylitis, leading to pain, swelling, and deformity, particularly in the long bones and joints.

Use this code when documentation explicitly links bone and joint pathology to a confirmed diagnosis of yaws. This applies to patients presenting with skeletal pain, swelling, or deformities where yaws is identified as the underlying etiology. Ensure the medical record clearly states the connection between the yaws infection and the musculoskeletal involvement.

• Always confirm the causal link between yaws and the bone/joint lesions; do not assume.
• Consider co-reporting with codes for active yaws infection if still present.
• Differentiate from other infectious or inflammatory arthropathies not caused by yaws.
