Hydroxyapatite deposition disease, left elbow

This code describes a condition characterized by the deposition of calcium hydroxyapatite crystals in the periarticular soft tissues of the left elbow. This crystalline deposition can lead to inflammation, pain, and restricted movement in the affected joint. It is a form of crystal arthropathy distinct from gout or pseudogout.

Use this code when documentation explicitly states hydroxyapatite deposition disease affecting the left elbow. Clinical scenarios include patients presenting with acute or chronic pain, swelling, and tenderness localized to the left elbow, with imaging (e.g., X-ray) confirming calcific deposits. Documentation should clearly specify the laterality.

• Ensure documentation specifies "hydroxyapatite" to differentiate from other crystal arthropathies.
• Verify laterality; this code is specific to the left elbow.
• Consider sequencing with codes for associated symptoms (e.g., pain, swelling) if they are not integral to the diagnosis.
