Familial chondrocalcinosis, left wrist

This code describes a genetic disorder characterized by the deposition of calcium pyrophosphate dihydrate crystals in the cartilage of the left wrist. This crystal deposition leads to inflammation and degenerative changes within the joint, often presenting with pain, swelling, and stiffness.

Apply this code when documentation confirms a diagnosis of familial chondrocalcinosis affecting the patient's left wrist. This diagnosis is typically supported by imaging studies (e.g., X-rays showing chondrocalcinosis) and a family history consistent with the inherited condition.

• Ensure the documentation explicitly specifies "familial" chondrocalcinosis and laterality (left wrist).
• Distinguish from acquired or idiopathic chondrocalcinosis, which would be coded differently (e.g., M11.232).
• Code any associated osteoarthritis or other joint pathologies separately, if documented.
