Pressr collapse of lung due to anesth during preg, third tri

This code signifies a collapsed lung (pneumothorax or atelectasis) occurring as a direct result of anesthetic administration during the third trimester of pregnancy. The collapse is specifically attributed to pressure changes or complications related to the anesthesia, rather than an underlying lung disease or trauma.

Apply this code when documentation clearly links a pressure-induced lung collapse to anesthesia given during the third trimester of pregnancy. This typically involves scenarios where positive pressure ventilation or other anesthetic techniques lead to barotrauma or atelectasis in the pregnant patient. Supporting documentation should include details of the anesthetic procedure, the onset of respiratory distress, and diagnostic imaging confirming lung collapse.

• Ensure the documentation explicitly states the lung collapse is "due to anesthesia" and specifies "pressure collapse."
• Verify the pregnancy trimester is documented as the third trimester.
• Sequence this code as a secondary diagnosis if the primary reason for the encounter is the delivery or other obstetric complication.
