Familial chondrocalcinosis, unspecified wrist

This code signifies a genetic predisposition to calcium pyrophosphate dihydrate (CPPD) crystal deposition in the cartilage and soft tissues of the wrist, leading to inflammation and joint damage. It represents a form of pseudogout that is inherited, specifically affecting an unspecified wrist joint.

Apply this code when documentation confirms a diagnosis of familial chondrocalcinosis affecting the wrist, and the specific wrist (left or right) is not documented. This diagnosis is typically supported by patient history, imaging (e.g., X-rays showing chondrocalcinosis), and genetic testing if available.

• Ensure documentation explicitly states "familial" to differentiate from idiopathic or secondary chondrocalcinosis.
• Avoid using this code if the laterality (left or right wrist) is specified; use the more specific codes M11.131 or M11.132.
• Consider co-reporting with codes for associated symptoms like wrist pain (e.g., M25.53-) or inflammatory arthritis (e.g., M05.9) if documented.
