Familial chondrocalcinosis, unspecified elbow

This code identifies a genetic disorder characterized by the deposition of calcium pyrophosphate crystals within the cartilage of joints, specifically affecting an unspecified elbow. This crystal deposition leads to inflammation, pain, and degenerative changes in the joint. It is distinct from sporadic chondrocalcinosis as it has a clear hereditary pattern.

Apply this code when documentation confirms a diagnosis of familial chondrocalcinosis impacting the elbow, but the specific laterality (right or left) is not specified. This diagnosis is typically supported by imaging studies showing chondrocalcinosis and a family history consistent with the inherited form of the condition.

• Ensure documentation explicitly states "familial" to differentiate from other forms of chondrocalcinosis.
• If laterality is documented (right or left elbow), use the more specific codes M11.121 or M11.122.
• Consider sequencing this code with codes for associated symptoms like arthropathy or pain, if applicable and documented.
