Other chondrocalcinosis, right wrist

This code signifies the presence of calcium pyrophosphate dihydrate (CPPD) crystal deposition in the cartilage and/or synovium of the right wrist, leading to joint inflammation and degeneration. It represents a form of pseudogout affecting this specific joint, distinct from primary or secondary forms of chondrocalcinosis.

Use this code when documentation explicitly states "other chondrocalcinosis" or "pseudogout" affecting the right wrist. This diagnosis is typically supported by imaging findings (e.g., radiography showing chondrocalcinosis) and/or synovial fluid analysis confirming CPPD crystals.

• Differentiate from M11.1- (familial chondrocalcinosis) and M11.0- (hereditary chondrocalcinosis) based on documented etiology.
• Ensure laterality is clearly specified in the medical record for the right wrist.
• Consider sequencing this code after any underlying conditions contributing to secondary chondrocalcinosis, if applicable and documented.
