Primary osteoarthritis, left wrist

This code signifies degenerative joint disease affecting the left wrist, not caused by trauma, infection, or other underlying conditions. It represents the chronic breakdown of cartilage and bone within the left wrist joint, leading to pain, stiffness, and reduced range of motion.

Apply this code when documentation explicitly states primary osteoarthritis of the left wrist. This diagnosis is typically supported by clinical examination findings (e.g., crepitus, tenderness, swelling) and imaging studies (e.g., X-rays showing joint space narrowing, osteophytes).

• Ensure the documentation specifies "primary" osteoarthritis to differentiate from secondary forms.
• Verify the laterality is clearly documented as "left wrist."
• Do not use this code if the osteoarthritis is a result of a previous injury or another systemic condition; instead, look for codes indicating secondary osteoarthritis.
