Other chondrocalcinosis, right shoulder

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

Use this code when documentation explicitly states "chondrocalcinosis" or "CPPD" affecting the right shoulder, and the specific type is not otherwise specified (e.g., familial, post-traumatic). Supporting documentation includes imaging reports (X-ray, ultrasound, MRI) showing calcification within the joint cartilage or synovial fluid analysis confirming CPPD crystals.

• Ensure laterality is clearly documented as "right shoulder" to support this specific code.
• Distinguish from gout (M10.-) or other crystal arthropathies; chondrocalcinosis involves CPPD crystals, not urate crystals.
• Code any associated manifestations, such as synovitis or effusion, with additional codes if documented.
