Angina pectoris with documented spasm

This code signifies chest pain or discomfort (angina pectoris) that is specifically attributed to a spasm of the coronary arteries. This spasm temporarily narrows the arteries, reducing blood flow to the heart muscle, even in the absence of significant atherosclerotic blockages. It is often referred to as vasospastic angina or Prinzmetal's angina.

Use this code when the patient presents with anginal symptoms and diagnostic testing, such as angiography with provocative testing or Holter monitoring, confirms the presence of coronary artery spasm. Documentation should clearly state "vasospastic angina," "Prinzmetal's angina," or "angina with documented spasm."

• Ensure documentation explicitly states "documented spasm" to support this specific code.
• Do not use this code for angina due to fixed atherosclerotic disease without evidence of spasm.
• Consider sequencing this code as the primary diagnosis if the spasm is the sole cause of the angina, or as a secondary diagnosis if it coexists with other coronary artery disease.
