Familial chondrocalcinosis, right shoulder

This code signifies a genetic disorder characterized by the deposition of calcium pyrophosphate dihydrate crystals within the cartilage of the right shoulder joint. This crystal deposition leads to inflammation, pain, and degenerative changes, often mimicking osteoarthritis. It is distinct from sporadic chondrocalcinosis due to its inherited nature.

Apply this code when documentation explicitly states a diagnosis of familial chondrocalcinosis affecting the patient's right shoulder. This diagnosis should be supported by clinical findings, imaging (e.g., radiography showing chondrocalcinosis), and a family history consistent with the inherited form of the condition.

• Ensure documentation specifies "familial" to differentiate from other forms of chondrocalcinosis.
• Verify the laterality is explicitly stated as "right shoulder" to avoid incorrect assignment.
• Consider co-reporting with codes for associated symptoms like arthralgia (M25.511) or effusion (M25.411) if documented.
