Secondary osteoarthritis, left elbow

This code signifies degenerative joint disease affecting the left elbow, which has developed as a consequence of another underlying condition or injury, rather than primary idiopathic osteoarthritis. This secondary form of osteoarthritis results in cartilage breakdown, pain, stiffness, and reduced range of motion in the elbow joint.

Apply this code when documentation clearly states "secondary osteoarthritis of the left elbow" or when osteoarthritis of the left elbow is explicitly linked to a prior trauma (e.g., fracture, dislocation) or systemic condition (e.g., rheumatoid arthritis, gout). The medical record must specify the left side and indicate a secondary etiology.

• Ensure the documentation specifies "secondary" and not "primary" osteoarthritis.
• Always code the underlying cause of the secondary osteoarthritis first, if known and actively treated.
• Verify laterality; this code is specific to the left elbow.
