Problem: A patient with severe arteriosclerotic heart disease (ASHD) of native arteries, unstable angina and severe COPD was admitted for a coronary artery bypass graft (CABG). An open 3-vessel CABG with the left internal mammary artery anastomosed to the left anterior descending coronary artery and separate greater saphenous vein grafts harvested endoscopically from the left leg, to the obtuse marginal branch and posterior descending coronary artery.
What are the both the ICD-10-CM and ICD-10-PCS codes assigned for this patient?
Hint: There are two (2) ICD-10-CM diagnosis codes and three (3) ICD-10-PCS codes.
