Hydroxyapatite deposition disease, right hand

This code signifies a condition characterized by the abnormal deposition of calcium hydroxyapatite crystals within the soft tissues of the right hand, often leading to pain, inflammation, and impaired function. It is a form of crystal deposition arthropathy, distinct from gout or pseudogout.

Apply this code when documentation explicitly states hydroxyapatite deposition disease affecting the right hand. Supporting clinical notes should include findings such as calcific deposits on imaging (e.g., X-ray, ultrasound) and symptoms localized to the right hand.

• Ensure laterality is clearly documented as "right hand" to support this specific code.
• Do not confuse with other crystal arthropathies like gout (M10.-) or calcium pyrophosphate deposition disease (M11.1-).
• Look for specific mention of "hydroxyapatite" or "calcific tendinitis/bursitis" in the context of the right hand.
