Familial chondrocalcinosis, right wrist

This code signifies a genetic disorder characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals within the cartilage of the right wrist joint. This crystal deposition leads to inflammation, pain, and degenerative changes, often mimicking osteoarthritis.

Apply this code when documentation explicitly states a diagnosis of familial chondrocalcinosis affecting the right wrist. Supporting documentation should include a family history of CPPD disease, imaging findings (e.g., radiography showing chondrocalcinosis), and clinical symptoms localized to the right wrist.

• Ensure "familial" is documented; otherwise, consider M11.231 for other chondrocalcinosis.
• Laterality is crucial; verify "right wrist" is clearly stated in the medical record.
• Do not confuse with gout (M10.-) or other crystal arthropathies without specific CPPD documentation.
