A66.9 is a billable ICD-10 code used to specify a medical diagnosis of yaws, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like A66.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Secondary lesion of yaws
- Secondary stage of yaws
- Tertiary lesion of yaws
- Yaws-. a systemic non-venereal infection of the tropics caused by treponema pallidum subspecies pertenue.
- Treponema pallidum-. the causative agent of venereal and non-venereal syphilis as well as yaws.
- Early Yaws-. early yaws includes primary and secondary stages of yaws, endemic tropical treponemal nonvenereal infection: development of initial lesion at inoculation site followed by widespread dissemination of treponemes and generalized secondary granulomatous lesions that may relapse repeatedly.
- Late Yaws-. late yaws is the tertiary, non-contagious stage of yaws, endemic tropical treponemal nonvenereal infection. late yaws is characterized by destructive and deforming lesions of the skin, bones, and joints.
- Yaws-. an endemic, infectious, nonvenereal disease in humans that presents mainly in children younger than 15 years. the disease occurs primarily in warm, humid, tropical areas of africa, asia, south america, and oceania, among poor rural populations where conditions of overcrowding and poor sanitation prevail. infection with treponema pertenue, a subspecies of treponema pallidum, causes the disease.

Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods, or spirals. They are so small that a line of 1,000 could fit across a pencil eraser. Most types of don't make you sick. Many types are helpful. Some of them help to digest food, destroy disease-causing cells, and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese.
But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.
Antibiotics are the usual treatment. When you take antibiotics, follow the directions carefully. Each time you take antibiotics, you increase the chances that bacteria in your body will learn to resist them causing antibiotic resistance. Later, you could get or spread an infection that those antibiotics cannot cure.
