ICD-10 Code A66.7 – Other manifestations of yaws (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A66.7 – Other manifestations of yaws
What it is
A66.7 identifies other clinical manifestations of yaws, a treponemal infection. Use it when documentation specifies yaws-related findings that do not fit a more specific yaws code.
Clinical signs
Clinical features vary; refer to documentation. Yaws may involve skin, bone, or soft tissue findings, and the record should support that the manifestation is attributable to yaws.
When to use this code
Use A66.7 when the provider documents a yaws manifestation that is not better described by another A66 code. It is appropriate when the note links the finding to yaws and does not identify a more specific category. Check documentation if the manifestation is unclear.
Do not use for
Do not use this code for yaws cases that have a more specific ICD-10-CM code. Do not assign it for unrelated skin, bone, or infectious conditions without documentation connecting them to yaws.
Coding tip
Confirm that the chart explicitly ties the manifestation to yaws before assigning A66.7.
