Hydroxyapatite deposition disease, right wrist

This code signifies a condition where calcium hydroxyapatite crystals deposit in the soft tissues around the right wrist joint, leading to inflammation, pain, and restricted movement. It is a form of crystal arthropathy, distinct from gout or pseudogout.

Apply this code when documentation explicitly states hydroxyapatite deposition disease affecting the right wrist. This diagnosis is typically confirmed by imaging studies (e.g., X-ray showing calcifications) and clinical presentation of acute or chronic wrist pain.

• Ensure laterality is clearly documented (right wrist in this case).
• Do not confuse with other crystal arthropathies like gout (M10.-) or calcium pyrophosphate deposition disease (M11.1-).
• Look for associated symptoms or complications (e.g., M25.531 for right wrist pain) to code additionally if documented.
