2025 ICD-10-CM code A66.7

Other manifestations of yaws.This includes manifestations like juxta-articular nodules and mucosal yaws.

Code A66.7 should be used when the manifestation of yaws is not covered by a more specific code within the A66 category.It is important to distinguish yaws from other skin conditions and other treponemal diseases like syphilis.

Medical necessity for the treatment of yaws is established by the presence of characteristic lesions and/or positive diagnostic tests. Treatment is necessary to prevent further progression of the disease, including bone and joint damage, and to prevent transmission to others.

A patient with yaws usually develops a red or tan, itchy, generally painless, raspberry–looking skin lesion (mother yaw) at the site of entry a few weeks after infection followed by more sores, bone pain, scarring, and bone and finger swelling as well as other symptoms associated with the other named manifestation. In severe or untreated cases, the patient may develop skin or bone disfigurement, leading to disability. Providers diagnose the condition based on the patient’s symptoms, exposure history, physical examination, and environmental conditions. Dark–field microscopic testing of the patient’s skin lesion sample can detect the organism. Treatment includes antibiotics, most commonly penicillin; antibiotics such as tetracycline, erythromycin, or doxycycline may be given to patients allergic to penicillin.

In simple words: This code represents other symptoms of yaws, a skin infection, not covered by other codes.This could include sores near joints or on mucous membranes.

Other manifestations of yaws refer to a clinical presentation of yaws not represented by another code in this category, such as yaws nodules next to joints (juxta-articular) and on the mucosa. Yaws is a chronic infectious disease caused by the bacterium Treponema pallidum pertenue, which usually affects children living in poor hygiene areas with warm, tropical climates, typically transmitted via cuts in the skin after contact with an infected person’s skin.

Example 1: A patient presents with yaws nodules located next to the joints of the hand.This unusual presentation is classified as A66.7., A child from a tropical region presents with mucosal lesions consistent with yaws, but without the typical "mother yaw" lesion. The mucosal involvement warrants the use of code A66.7., A patient with a history of yaws develops painful bone lesions years after the initial infection. While bone involvement can occur in secondary yaws, if it's a late manifestation with unusual features, A66.7 is appropriate.

Documentation should clearly describe the specific manifestation of yaws, its location (e.g., juxta-articular, mucosal), and any associated symptoms. Any diagnostic testing performed (e.g., dark-field microscopy) should also be documented. The patient's travel history and possible exposure to the bacteria should be noted.

** Yaws, although similar to syphilis, is not a sexually transmitted infection.It is spread through direct contact with infected lesions, primarily among children in tropical regions with poor sanitation.
