CD73 deficiency causing arterial calcification

This code identifies arterial calcification that is specifically caused by a deficiency in CD73 (ecto-5'-nucleotidase). This is a rare genetic disorder characterized by the abnormal deposition of calcium in the arterial walls, leading to vascular stiffness and potential cardiovascular complications.

Apply this code when documentation clearly links arterial calcification to a confirmed CD73 deficiency. This typically involves genetic testing results confirming the deficiency and imaging studies demonstrating arterial calcification. Use for patients diagnosed with this specific genetic cause of vascular calcification.

• Ensure documentation explicitly states "CD73 deficiency" as the cause of arterial calcification.
• Do not use for arterial calcification of unknown etiology or due to other genetic causes.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, followed by codes for specific manifestations or complications of the arterial calcification.
