0.000What This Code Means
Narrowing of other coronary artery bypass grafts with unspecified or undocumented chest pain.
Coding Tips
- •This is the least specific code in the series; use only when angina type is not documented
- •Query provider if angina characteristics are documented but not specified in the code selection
Clinical Significance
This code represents atherosclerosis in other coronary bypass graft types with unspecified angina. Both the 'other' graft designation and 'unspecified' angina type indicate documentation limitations. This code should prompt a thorough review of operative reports for graft type and clinical notes for angina characterization to achieve optimal coding specificity.
Documentation Requirements
- ✓History of CABG with graft type that cannot be classified as autologous vein/artery or nonautologous biological
- ✓Evidence of atherosclerotic disease in the graft
- ✓Angina symptoms documented without specific type characterization
- ✓Provider query attempted for both graft type and angina classification
- ✓Treatment plan for graft disease and angina management
Excludes 1 — Do NOT code together
- unspecified angina pectoris without atherosclerosis of other coronary artery bypass graft(s) (I20.9)
Commonly Confused Codes
I25.790 — Other CABG with unstable angina; more specific when unstable documentedI25.798 — Other CABG with other forms of angina; use when angina is characterizedI25.709 — Unspecified CABG with unspecified angina; even less specific on graft typeI25.810 — CABG atherosclerosis without angina; no angina present
