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.
The pulmonary artery transports blood from the heart to the lungs. While most major arteries branch off from the aorta, the main pulmonary artery extends from the right ventricle of the heart and branches into left and right pulmonary arteries. The left and right pulmonary arteries extend to the left lung and right lungs. The pulmonary arteries are unique in that unlike most arteries which carry oxygenated blood to other parts of the body, the pulmonary arteries carry de-oxygenated blood to the lungs. After picking up oxygen, the oxygen rich blood is returned to the heart via the pulmonary veins. 1 of 1.
