0.000What This Code Means
Plaque buildup in coronary artery bypass grafts causing chest pain, but the specific type of angina is not specified in the medical record.
Coding Tips
- •This is a default code when angina is present but type is not documented
- •Query the provider if possible to obtain more specific angina classification for accurate coding
Clinical Significance
This code captures coronary artery bypass graft atherosclerosis with angina pectoris where neither the graft type nor angina type is specified. It reflects ongoing ischemic heart disease in a post-surgical patient, indicating graft degeneration and persistent symptomatology. Documentation of the specific graft type and angina classification should be pursued to achieve optimal code specificity.
Documentation Requirements
- ✓History of coronary artery bypass graft surgery with graft type identified if possible
- ✓Clinical evidence of atherosclerotic disease within the bypass graft (catheterization, CT angiography, or clinical diagnosis)
- ✓Documentation of angina symptoms — chest pain character, frequency, triggers, and relief measures
- ✓Current treatment plan including anti-anginal medications
- ✓Provider assessment linking angina to graft atherosclerosis
Excludes 1 — Do NOT code together
- unspecified angina pectoris without atherosclerosis of coronary artery bypass graft (I20.9)
Commonly Confused Codes
I25.119 — Atherosclerosis of native coronary artery with unspecified angina; use when disease is in native vessels, not bypass graftsI25.710 — Atherosclerosis of autologous vein CABG with unstable angina; more specific graft type and unstable angina patternI25.10 — Atherosclerotic heart disease of native coronary artery without angina; lacks the angina componentI20.9 — Angina pectoris, unspecified; does not capture the underlying graft atherosclerosis
