Other specified crystal arthropathies, right wrist

This code signifies a non-gouty, non-CPPD (calcium pyrophosphate dihydrate) crystal deposition disease affecting the right wrist joint. It encompasses various less common crystal-induced arthropathies, such as those caused by calcium oxalate or hydroxyapatite, leading to inflammation and pain.

Apply this code when documentation clearly indicates a crystal arthropathy of the right wrist that is not identified as gout or pseudogout. Supporting documentation should include imaging findings (e.g., radiography, ultrasound) demonstrating crystal deposits, and/or synovial fluid analysis confirming the presence of specific crystals other than urate or CPPD.

• Ensure the specific crystal type is documented if known, even if it falls under "other specified."
• Verify laterality; this code is specific to the right wrist.
• Do not use for gout (M10.-) or pseudogout (M11.1-) of the wrist.
