Other chondrocalcinosis, left hand

This code signifies the presence of calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, also known as pseudogout, affecting the left hand. This condition leads to inflammation and pain in the joints due to the accumulation of these crystals in the cartilage.

Apply this code when documentation confirms chondrocalcinosis in the left hand, specifically when the type is not specified as familial or due to trauma. Supporting documentation should include physician notes detailing the diagnosis of CPPD in the left hand, often confirmed by imaging (e.g., X-ray showing chondrocalcinosis) or synovial fluid analysis.

• Ensure the laterality (left hand) is clearly documented and matches the code.
• Differentiate from M11.1- (familial chondrocalcinosis) or M11.8- (other specified chondrocalcinosis) if the cause is known.
• Code any associated arthritis or other joint conditions separately if documented.
