Yaws, unspecified

This code represents yaws, a chronic tropical infection caused by the spirochete Treponema pallidum pertenue, when the specific stage or manifestation of the disease is not documented. Yaws primarily affects the skin, bones, and joints, typically presenting with characteristic lesions. It is a non-venereal treponematosis.

Use this code when the medical record clearly indicates a diagnosis of yaws, but lacks specific details regarding its stage (e.g., primary, secondary, tertiary) or the particular anatomical site affected. This code is appropriate when the documentation only states "yaws" without further elaboration.

• Avoid using this code if more specific documentation is available; always query for greater specificity if possible.
• This code is for an unspecified presentation of yaws; differentiate from other treponematoses like syphilis (ICD-9-CM 090-097) or pinta (ICD-9-CM 103.x).
• Ensure the documentation supports a confirmed diagnosis of yaws, not merely a suspected case.
