Familial chondrocalcinosis, left hand

This code signifies a genetic disorder characterized by the abnormal deposition of calcium pyrophosphate crystals within the cartilage of the left hand joints. 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 left hand. This diagnosis is typically confirmed through imaging (e.g., X-ray showing chondrocalcinosis) and a family history consistent with the inherited condition.

• Ensure documentation specifies "familial" to differentiate from idiopathic or secondary chondrocalcinosis.
• Laterality (left hand) must be clearly documented; do not use for bilateral or unspecified hand involvement.
• Code any associated arthropathy or other manifestations of chondrocalcinosis separately if documented.
