Other chondrocalcinosis, unspecified hand

This code signifies a form of calcium pyrophosphate deposition disease (CPPD) affecting an unspecified hand, where the calcium crystals accumulate in the cartilage. It represents a chronic arthropathy characterized by crystal deposition, leading to inflammation and degenerative changes in the joint.

Use this code when documentation indicates chondrocalcinosis in the hand, but the specific type (e.g., familial, post-traumatic) is not specified. It is appropriate when the provider has diagnosed chondrocalcinosis of the hand, and imaging (e.g., X-ray showing chondrocalcinosis) or synovial fluid analysis confirms the presence of calcium pyrophosphate crystals.

• Ensure the documentation clearly specifies "chondrocalcinosis" and "hand" as the affected site.
• Avoid using this code if a more specific type of chondrocalcinosis (e.g., M11.1- for familial) is documented.
• Always code to the highest level of specificity; if the laterality (right or left hand) is known, a more specific code should be used.
