Familial chondrocalcinosis, left ankle and foot

This code signifies a genetic disorder characterized by the deposition of calcium pyrophosphate crystals in the cartilage of the left ankle and foot joints. This crystal deposition leads to inflammation, pain, and degenerative changes within the affected joint structures. It represents a specific manifestation of chondrocalcinosis with a familial predisposition.

Apply this code when documentation explicitly states a diagnosis of familial chondrocalcinosis affecting the left ankle and/or foot. This diagnosis is typically confirmed through imaging studies (e.g., X-ray showing chondrocalcinosis) and a family history suggestive of the condition. Use this code for patients presenting with symptoms such as pain, swelling, and stiffness in the left ankle and foot, where familial chondrocalcinosis has been established as the etiology.

• Ensure documentation specifies "familial" chondrocalcinosis; otherwise, a non-familial code may be more appropriate.
• Verify the laterality (left) and specific anatomical site (ankle and foot) are clearly documented.
• Do not confuse with other forms of arthropathy or crystal deposition diseases without the familial component.
