0.000What This Code Means
Plaque buildup in an autologous artery bypass graft causing chest pain, but the specific type of angina is not specified.
Coding Tips
- •Use this code only when atherosclerosis of the graft is documented but the angina type is unclear or not specified
- •Review documentation to determine if a more specific code (720, 721, or 722) should be used instead
Clinical Significance
This code captures atherosclerosis of an autologous artery coronary bypass graft with angina pectoris where the specific type of angina is not documented. While it establishes graft disease with ischemic symptoms, the unspecified angina designation represents a documentation opportunity. Querying the provider for the angina pattern could improve coding specificity and, in the case of unstable angina, impact risk adjustment.
Documentation Requirements
- ✓History of CABG with autologous artery graft (internal mammary or radial artery) specified
- ✓Evidence of atherosclerosis in the arterial graft
- ✓Documentation of angina symptoms present even though specific type is not characterized
- ✓Provider query attempted to determine angina classification
- ✓Treatment plan for graft disease and angina management
Excludes 1 — Do NOT code together
- unspecified angina pectoris without atherosclerosis of autologous artery coronary artery bypass graft(s) (I20.9)
Commonly Confused Codes
I25.720 — Autologous artery CABG with unstable angina; use when unstable pattern is documentedI25.728 — Autologous artery CABG with other forms of angina; use when angina type is documented but doesn't fit specific categoriesI25.709 — CABG atherosclerosis with unspecified angina, graft type unspecified; less specific on graft typeI25.810 — CABG atherosclerosis without angina; no angina component
