Familial chondrocalcinosis, right hand

This code signifies a genetic predisposition to calcium pyrophosphate dihydrate (CPPD) crystal deposition in the cartilage of the right hand, leading to joint inflammation and damage. It represents a specific form of chondrocalcinosis with a hereditary component affecting a particular anatomical site.

Apply this code when documentation explicitly states "familial chondrocalcinosis" affecting the right hand. This diagnosis is typically supported by a family history of CPPD, radiographic evidence of chondrocalcinosis in the right hand, and clinical symptoms consistent with crystal-induced arthritis.

• Ensure documentation specifies "familial" to differentiate from idiopathic or secondary chondrocalcinosis.
• Laterality (right hand) is integral to this code; do not use for bilateral or left-hand involvement.
• Code any associated acute pseudogout flares or chronic arthropathy separately, if documented.
