0.000What This Code Means
Plaque buildup in an autologous artery bypass graft causing severe, treatment-resistant chest pain.
Coding Tips
- •Verify that the angina is documented as refractory (resistant to standard treatment)
- •Ensure documentation supports that multiple medications have been tried without adequate relief
Clinical Significance
This code captures atherosclerosis in an autologous artery bypass graft with refractory angina — persistent chest pain despite maximized medical therapy. Given that arterial grafts typically have better patency, refractory angina in this setting often indicates severe multi-vessel disease with limited revascularization options. These patients represent a challenging clinical population requiring advanced pain management and possibly experimental therapeutic approaches.
Documentation Requirements
- ✓History of CABG with specific autologous arterial graft type documented
- ✓Evidence of atherosclerotic disease in the arterial graft
- ✓Documentation that angina persists despite optimal medical therapy at maximum tolerated doses
- ✓Documentation that revascularization options have been exhausted or are not feasible
- ✓Ongoing management plan for refractory symptoms including advanced therapies if applicable
Commonly Confused Codes
I25.712 — Autologous vein CABG with refractory angina; vein graft, not arterialI25.720 — Autologous artery CABG with unstable angina; acute instability rather than chronic treatment resistanceI25.728 — Autologous artery CABG with other forms of angina; for characterized angina not meeting refractory criteriaI20.8 — Other forms of angina pectoris; lacks graft-specific context
