No CPT code was found for "craniotomy clipping of right posterior communicating artery aneurysm."
Non ruptured aneurysm is 437.3 and ruptured is 430
The right side of the heart receives blood from the right coronary artery and the posterior descending artery.
right coronary artery
The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.
right coronary artery
They are right behind (directly posterior to) the tibial malleolus on the medial side
They branch off from the right coronary artery which arises from the aorta.
It connects left and right anterior cerebral arteries
The left coronary artery branches into the anterior interventricular artery which supplies blood to the interventricular septum and anterior walls of both ventricles and the circumflex artery which supplies the left atrium and the posterior walls of the left ventricle. The right coronary artery branches into the right marginal artery which serves the myocardium of the lateral right side of the heart and the posterior interventricular artery which supplies the posterior ventricular walls.Reference: Marieb, Elain N.

No need, the left coronary arises from the left posterior sinus of the ascending aorta.
The coronary sinus runs in the posterior coronary sulcus. In the anterior coronary sulci the stems of the coronary artery run. The circumflex branch of the left and the extension of the right coronary artery that becomes the posterior descending artery run around the coronary sulcus from front to back
