Hydroxyapatite deposition disease, unspecified elbow

This code represents a condition characterized by the deposition of calcium hydroxyapatite crystals in the soft tissues around the elbow joint, leading to pain and inflammation. It is a form of crystal arthropathy, often presenting with acute or chronic discomfort.

Use this code when documentation indicates hydroxyapatite deposition disease affecting the elbow, and the specific laterality (right or left) is not specified. This diagnosis is typically supported by imaging studies (e.g., X-rays showing calcifications) and clinical presentation.

• Ensure documentation clearly states the elbow as the affected joint.
• If laterality is specified (e.g., right elbow), use the more specific code (M11.021 or M11.022).
• Do not confuse with other crystal arthropathies like gout or pseudogout, which have distinct ICD-10-CM codes.
