Other chondrocalcinosis, unspecified wrist

This code describes a form of crystal deposition arthropathy affecting an unspecified wrist, characterized by the accumulation of calcium pyrophosphate dihydrate (CPPD) crystals in articular cartilage and other periarticular tissues. This leads to inflammation, pain, and degenerative changes within the joint.

Use this code when documentation specifies chondrocalcinosis of the wrist, but the laterality (right or left) is not explicitly stated. This diagnosis is typically supported by radiographic evidence of chondrocalcinosis or aspiration of CPPD crystals from the joint fluid.

• Do not use this code if the laterality of the affected wrist is documented; instead, select the more specific code for right (M11.231) or left (M11.232) wrist.
• Distinguish from gout (M10.-) which involves monosodium urate crystal deposition.
• Consider sequencing this code after a more specific code for the underlying cause if known, such as hemochromatosis or hyperparathyroidism.
