Yaws of bones
ICD-10 A66.4 is a billable code used to indicate a diagnosis of yaws of bones.
Yaws is a chronic infectious disease caused by the spirochete Treponema pallidum pertenue, primarily affecting the skin, bones, and cartilage. Yaws of bones specifically refers to the involvement of the skeletal system, leading to painful lesions and deformities. The disease is endemic in tropical regions, particularly in parts of Africa, Asia, and the Pacific Islands. It is transmitted through direct skin contact with the lesions of an infected person, making it more prevalent in communities with poor sanitation and limited access to healthcare. Clinical manifestations include bone pain, swelling, and deformities, often resembling other conditions such as osteomyelitis or syphilis. Diagnosis is typically made through clinical evaluation and serological tests. Treatment involves the administration of antibiotics, primarily benzathine penicillin, which is effective in curing the infection and preventing further complications. Early detection and treatment are crucial to prevent long-term skeletal damage and disability.
Detailed clinical history, laboratory results, and treatment plans.
Patients presenting with chronic skin lesions and bone pain in endemic areas.
Ensure accurate serological testing results are included in documentation.
Radiological findings, surgical notes if applicable, and follow-up care documentation.
Patients with bone deformities or pain attributed to yaws.
Document any differential diagnoses considered during evaluation.
Used to confirm diagnosis of yaws in patients presenting with symptoms.
Document the reason for testing and results.
Infectious disease specialists should ensure comprehensive testing is performed.
Common symptoms include skin lesions, bone pain, and deformities. Lesions may appear as nodules or ulcers on the skin, and bone involvement can lead to swelling and pain in affected areas.
