I25.710 Atherosclerosis of autologous vein coronary artery bypass graft(s) with unstable angina…

Coding notes

From the ICD-10-CM FY2027 (effective October 1, 2026) tabular list. Notes on a parent code or category apply here too.

Excludes1

Not coded together with this code. The exception is when the two conditions are unrelated to each other.

• unstable angina without atherosclerosis of autologous vein coronary artery bypass graft(s) (I20.0)
• atherosclerosis of bypass graft(s) of transplanted heart without angina pectoris (I25.812)
• atherosclerosis of coronary artery bypass graft(s) without angina pectoris (I25.810)
• atherosclerosis of native coronary artery of transplanted heart without angina pectoris (I25.811)

Excludes2

Not part of this code, but both can be coded when both are documented.

• embolism or thrombus of coronary artery bypass graft(s) (T82.8-)
• non-ischemic myocardial injury (I5A)

Use additional code

Add a second code for the following, when documented.

• code, if applicable, to identify:
• coronary atherosclerosis due to calcified coronary lesion (I25.84)
• coronary atherosclerosis due to lipid rich plaque (I25.83)
• code to identify:
• chronic total occlusion of coronary artery (I25.82)
• exposure to environmental tobacco smoke (Z77.22)
• history of tobacco dependence (Z87.891)
• occupational exposure to environmental tobacco smoke (Z57.31)
• tobacco dependence (F17.-)
• tobacco use (Z72.0)

Code also

A second code may be needed. Sequencing depends on the encounter.

• the presence of hypertension (I10-I1A)
