Coding tip: Correctly sequence CPT codes on claim forms. Ambulatory Surgery Reimbursement Update, May 29, 2007. You should sequence CPT codes on Medicare claims from highest to lowest payment groupings. You should follow the same sequencing on claims from payers with which your ASC facility is contracted who also use groupers.
In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle. It is short and wideâapproximately 5 centimetres (2.0 in) in length and 3 centimetres (1.2 in) in diameter.he pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.
Answer by Andrew Lardie. Confidence votes 8. The pulmonary artery is the blood vessel that leads away from the heart (Artery=Away), toward the lungs. It is pumping blood to that lungs that just returned from the body (via the vena cava, into the right atrium).So the blood in the pulmonary artery has the lowest concentration of O2 and the highest concentration of CO2. It is just about to pick up lots of oxygen, once it gets to the lungs.t is pumping blood to that lungs that just returned from the body (via the vena cava, into the right atrium). So the blood in the pulmonary artery has the lowest concentration of O2 and the highest concentration of CO2.
