Short answer · Medically reviewed summary · Last updated: 2026-05-08
Kienböck disease, also known as lunatomalacia, is classified under ICD-10 code M93.1 (Kienböck's disease of adult) and historically under ICD-9 code 732.3. These codes are essential for medical billing and clinical documentation to track this condition, which involves the progressive avascular necrosis of the lunate bone in the wrist. What is the clinical significance of Kienböck disease? Kienböck disease is a rare disorder characterized by the loss of blood supply to the lunate bone, leading to its collapse and subsequent wrist pain, stiffness, and weakness.

What is the clinical significance of Kienböck disease?
Kienböck disease is a rare disorder characterized by the loss of blood supply to the lunate bone, leading to its collapse and subsequent wrist pain, stiffness, and weakness. Within our DiseaseMaps community, 186 people with Kienböck disease have shared their experiences, highlighting the importance of early detection to prevent secondary osteoarthritis. Understanding the classification of Kienböck disease through its ICD codes helps clinicians standardize treatment pathways.
How is Kienböck disease diagnosed?
Diagnosis of Kienböck disease typically involves a combination of clinical assessment and advanced imaging. Physicians look for specific patterns of bone density changes and fragmentation. The following diagnostic tools are commonly utilized:
- X-ray imaging: Used to identify the Lichtman stage of Kienböck disease.
- MRI scans: Essential for early detection of ischemia before structural collapse occurs.
- CT scans: Helpful in assessing the extent of bone fragmentation in advanced Kienböck disease.
Is Kienböck disease hereditary?
There is no evidence that Kienböck disease is a strictly hereditary or genetic condition. Instead, the development of Kienböck disease is often linked to anatomical variations, such as ulnar variance (where the ulna is shorter than the radius), which places abnormal stress on the lunate bone.
