Hydroxyapatite deposition disease, left hip

This code signifies a condition where calcium hydroxyapatite crystals deposit in and around the soft tissues of the left hip joint, leading to pain, inflammation, and restricted movement. It is a form of crystal arthropathy, distinct from other types of arthritis.

Apply this code when documentation explicitly states a diagnosis of hydroxyapatite deposition disease affecting the left hip. Supporting clinical evidence typically includes imaging findings (e.g., X-rays showing calcifications) and patient symptoms localized to the left hip.

• Ensure the documentation specifies "hydroxyapatite" and not another type of crystal deposition (e.g., gout, pseudogout).
• Verify the laterality is clearly documented as "left hip" to avoid incorrect coding.
• Do not use this code for general calcific tendinitis or bursitis without specific mention of hydroxyapatite deposition disease.
