Other chondrocalcinosis, right hand

This code signifies the presence of calcium pyrophosphate dihydrate (CPPD) crystal deposition disease, also known as pseudogout, affecting the right hand. It indicates a form of arthritis caused by these crystal deposits within the joint cartilage and surrounding tissues, leading to inflammation and pain.

Apply this code when documentation explicitly states a diagnosis of chondrocalcinosis or pseudogout specifically located in the right hand, and the type is not specified as familial or due to trauma. Supporting documentation would include imaging reports (e.g., X-rays showing chondrocalcinosis) and physician notes detailing symptoms and diagnosis in the right hand.

• Ensure the documentation clearly specifies "right hand" to avoid laterality errors.
• Distinguish from M11.1- (familial chondrocalcinosis) and M11.0- (familial chondrocalcinosis due to trauma) if the cause is known.
• Code any associated acute pseudogout flare (M11.841) separately if present and documented.
