Secondary osteoarthritis, right wrist

This diagnosis code signifies degenerative joint disease affecting the right wrist, which has developed as a consequence of another underlying condition or injury rather than primary age-related wear and tear. It indicates cartilage breakdown and bone changes in the radiocarpal or intercarpal joints of the right hand, stemming from a known secondary cause.

This code is appropriate when documentation specifies osteoarthritis of the right wrist and explicitly links it to a secondary etiology, such as a previous fracture, inflammatory arthritis (e.g., rheumatoid arthritis), or metabolic disorder. Supporting documentation should clearly state "secondary osteoarthritis" or provide a causal link between an underlying condition and the wrist's degenerative changes.

• Ensure the medical record clearly distinguishes between primary and secondary osteoarthritis; if the cause is not specified, a primary osteoarthritis code may be more appropriate.
• Always code the underlying cause of the secondary osteoarthritis first, if known and actively treated or relevant to the current encounter.
• Differentiate from post-traumatic osteoarthritis; while post-traumatic is a type of secondary OA, specific codes exist for it if the trauma is the direct cause.
