Secondary osteoarthritis, left wrist

This code signifies degenerative joint disease of the left wrist that develops as a consequence of another underlying condition, such as trauma, infection, or a metabolic disorder. It indicates cartilage breakdown and bone changes in the radiocarpal or intercarpal joints, specifically affecting the patient's left side.

Apply this code when documentation clearly states "secondary osteoarthritis" or "post-traumatic arthritis" of the left wrist. Supporting documentation should identify the underlying cause if known, and specify the affected joint as the wrist.

• Always seek documentation of the underlying cause of the secondary osteoarthritis, if available, and code it first.
• Distinguish carefully between primary (idiopathic) and secondary osteoarthritis; this code is only for secondary forms.
• Ensure the laterality (left) is explicitly documented for accurate code assignment.
