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 right ventricle then pumps blood through the pulmonary artery into the lungs. 4. In the lungs, tiny blood vessels called capillaries absorb carbon diox-ide from the blood and replace it with oxygen. 5. Oxygenated blood then flows through the pulmonary vein and into the left atrium.
