Osteochondrosis (juvenile) of carpal lunate, right hand

This code signifies Kienbock's disease affecting the lunate bone in the right hand. Kienbock's disease is a rare, progressive osteonecrosis (avascular necrosis) of the carpal lunate, leading to fragmentation and collapse of the bone. This condition primarily affects adolescents and young adults.

Apply this code for documented cases of juvenile osteochondrosis specifically involving the lunate bone of the right hand. This diagnosis is typically supported by imaging studies such as X-rays, MRI, or CT scans demonstrating lunate sclerosis, fragmentation, or collapse, along with clinical findings of wrist pain and stiffness.

• Ensure documentation specifies "juvenile" osteochondrosis and clearly identifies the right hand.
• Distinguish from other forms of wrist osteochondrosis or general wrist pain; this code is highly specific to Kienbock's disease of the lunate.
• Consider sequencing with codes for associated symptoms like wrist pain (e.g., M25.531) or functional impairment, if applicable and documented.
