Primary osteoarthritis, right wrist

This code signifies degenerative joint disease affecting the right wrist, characterized by cartilage breakdown and bone spur formation, without a known underlying cause. It represents the initial or idiopathic form of osteoarthritis specifically impacting the radiocarpal or intercarpal joints of the right hand.

Apply this code when documentation clearly states "primary osteoarthritis of the right wrist" or "idiopathic osteoarthritis of the right wrist." This diagnosis is typically supported by imaging findings (e.g., X-rays showing joint space narrowing, osteophytes) and clinical symptoms such as pain, stiffness, and reduced range of motion in the right wrist.

• Ensure laterality is explicitly documented as "right wrist"; avoid using for unspecified or bilateral cases.
• Distinguish from secondary osteoarthritis, which would require an additional code for the underlying cause.
• Do not use if the osteoarthritis is due to trauma, infection, or another systemic condition.
