Diagnosis Code Designated for Refractory Angina Pectoris

October 20, 2022—The Society for Cardiovascular Angiography & Interventions (SCAI) recently announced that new ICD-10-CM codes have been added to properly reflect and document the condition of refractory angina pectoris. The chronic condition of angina in the setting of coronary artery disease that cannot be controlled by multiple treatment options has not had a dedicated diagnosis code, noted SCAI.

The changes for ICD-10-CM diagnosis codes in the 2023 code book are effective as of October 1, 2022.

The new code has been added to the I20 angina pectoris category as:

• I20.2 Refractory angina pectoris.

Additionally, SCAI advised that the I25 atherosclerosis category has been updated to include refractory angina. These new codes are:

• I25.112 Atherosclerosis heart disease of native coronary artery with refractory angina pectoris
• I25.702 Atherosclerosis of coronary artery bypass graft(s), unspecified, with refractory angina pectoris
• I25.712 Atherosclerosis of autologous vein coronary artery bypass graft(s) with refractory angina pectoris
• I25.722 Atherosclerosis of autologous artery coronary artery bypass graft(s) with refractory angina pectoris
• I25.732 Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with refractory angina pectoris
• I25.752 Atherosclerosis of native coronary artery of transplanted heart with refractory angina pectoris
• I25.762 Atherosclerosis of bypass graft of coronary artery of transplanted heart with refractory angina pectoris
• I25.792 Atherosclerosis of other coronary artery bypass graft(s) with refractory angina pectoris
