Familial chondrocalcinosis, unspecified hand

This code identifies a genetic disorder characterized by the deposition of calcium pyrophosphate crystals in the cartilage of joints, specifically affecting an unspecified hand due to familial inheritance. This crystal deposition leads to inflammation, pain, and degenerative changes within the joint. It is a form of pseudogout with a hereditary component.

Use this code when documentation confirms a diagnosis of familial chondrocalcinosis affecting the hand, but the specific laterality (right or left) is not specified. This diagnosis is typically supported by imaging studies showing chondrocalcinosis and a family history consistent with the condition. It is appropriate when the provider has not indicated a more specific anatomical site within the hand.

• Ensure documentation explicitly states "familial" to differentiate from idiopathic or secondary chondrocalcinosis.
• Avoid using this code if the specific hand (right or left) is documented; instead, use the more specific M11.141 or M11.142.
• Consider co-reporting with codes for associated symptoms like joint pain (M25.54-) or arthritis (M19.-) if documented.
