The branches of Coronary Artery
Right Coronary Artery
- Right marginal
- Right posterior descending (PDA)
Left Main Coronary Artery (LMCA)
- Left anterior descending branch (LAD)
- Diagonal
- Septal
- Circumflex (LCX)
- Obtuse marginal (OM)
- Posterior descending
- Posterolateral
*** When there are multiple coronary artery sites (Body Parts) being bypassed, a separate procedure is coded for each coronary artery site that uses a different device and/or a qualifier.
In order to consider that a Device is to be used, this needs to be a material (tissue) used as graft (separated) and not moved over. In the case of using Internal Mammary Artery, it is only loosened from one side and put towards the obstructed coronary artery. The internal mammary artery is not used as “free graft”; therefore, it would be considered no Device.
The selection of Qualifier determines the blood vessel bypassed from.
If an autograft is obtained from a different body part in order to accomplish the bypass procedure, a separate procedure is coded.
If the procedure is also performed with extracorporeal circulation (bypass machine), an additional code should be assigned.
Procedures that are included in bypass operations are not coded separately. These include hypothermia, cardioplegia, intraoperative pacing and chest tube insertions.
Question:
The coronary bypass grafts were performed. First was the use of left internal mammary artery over to the left circumflex coronary artery.
02100A9 is wrong.. The Device character is Z- No device. Please make note that just mover OVER, not dissected, hence NO DEVICE.
Question:
Using an open approach, the surgeon excised the patient’s right greater saphenous vein as graft, bringing blood from the aorta to the obtuse marginal branch, to the diagonal artery and to the proximal PDA.

- 06BP0ZZ, Excision of right greater saphenous vein, open approach
