Secondary osteoarthritis, unspecified elbow

This code signifies degenerative joint disease of the elbow that develops as a consequence of another underlying condition, such as trauma, infection, or a metabolic disorder. It indicates the osteoarthritis is not primary (idiopathic) and the specific elbow affected is not documented.

Apply this code when documentation clearly states "secondary osteoarthritis of the elbow" without specifying left or right. This diagnosis is supported by imaging findings (e.g., X-rays showing joint space narrowing, osteophytes) and a history of a predisposing factor leading to the joint degeneration.

• Ensure documentation explicitly states "secondary" to differentiate from primary osteoarthritis.
• If the laterality (left or right elbow) is specified, use the more specific codes (M19.221 or M19.222).
• Always code the underlying cause of the secondary osteoarthritis first, if known and applicable.
