Familial chondrocalcinosis, right elbow

This code signifies a genetic predisposition to calcium pyrophosphate dihydrate (CPPD) crystal deposition in the cartilage of the right elbow joint. This deposition leads to inflammation and degenerative changes, often mimicking osteoarthritis. It is a chronic, inherited form of chondrocalcinosis.

Apply this code when documentation explicitly states a diagnosis of familial chondrocalcinosis affecting the patient's right elbow. Supporting documentation should include family history of the condition, imaging findings (e.g., radiographs showing chondrocalcinosis), and clinical symptoms localized to the right elbow.

• Ensure "familial" is clearly documented to differentiate from other forms of chondrocalcinosis.
• Verify the laterality (right elbow) is explicitly stated in the medical record.
• Do not confuse with M11.10 (Familial chondrocalcinosis, unspecified site) or M11.221 (Other chondrocalcinosis, right elbow).
