Familial chondrocalcinosis, left hip

This code signifies a genetic disorder characterized by the deposition of calcium pyrophosphate dihydrate crystals within the cartilage of the left hip joint. This crystal deposition leads to inflammation, pain, and degenerative changes in the joint, often mimicking osteoarthritis.

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

• Ensure the documentation specifies "familial" to differentiate from sporadic chondrocalcinosis.
• Verify the laterality is clearly documented as "left hip"; do not assume.
• Consider co-reporting with codes for associated symptoms like pain (e.g., M25.552) or inflammatory arthritis (e.g., M1A.052) if documented.
