Familial chondrocalcinosis, left elbow

This diagnosis code signifies a genetic predisposition to calcium pyrophosphate dihydrate (CPPD) crystal deposition in the cartilage of the left elbow joint. This inherited condition leads to joint inflammation and degenerative changes, often resembling osteoarthritis.

Use this code when documentation explicitly states familial chondrocalcinosis affecting the left elbow. This typically occurs in patients with a family history of CPPD disease and confirmed crystal deposition via imaging or synovial fluid analysis in the specified joint.

• Ensure the documentation specifies "familial" to differentiate from idiopathic or secondary chondrocalcinosis.
• Verify the laterality is clearly documented as "left elbow."
• Do not confuse with M11.10 (familial chondrocalcinosis, unspecified site) or M11.121 (familial chondrocalcinosis, right elbow).
