I20 vs I25.7
I20 (Angina pectoris) compared with I25.7 (Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. I20 carries an Excludes1 note covering I25.7: “atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris (I25.7-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
