Other chondrocalcinosis, left elbow

This code signifies the presence of calcium pyrophosphate dihydrate (CPPD) crystal deposition in the cartilage of the left elbow joint, leading to inflammation and degenerative changes. It represents a form of crystal arthropathy distinct from gout, characterized by the accumulation of these specific crystals.

Use this code when documentation explicitly states "chondrocalcinosis" or "CPPD deposition disease" affecting the left elbow. This diagnosis is typically confirmed by imaging (e.g., X-ray showing chondrocalcinosis) or synovial fluid analysis identifying CPPD crystals.

• Ensure laterality is clearly documented as "left elbow" to support this specific code.
• Distinguish from gout (M10.-) or other arthropathies; chondrocalcinosis involves CPPD crystals, not urate.
• Code any associated symptoms, such as acute pseudogout flare (M11.122), as additional diagnoses.
