Cerebral anoxia due to anesth during preg, second trimester

This code signifies a lack of oxygen to the brain resulting from complications of anesthesia administered during the second trimester of pregnancy. This anoxic event leads to cerebral dysfunction or damage in the pregnant patient.

Apply this code when documentation clearly states cerebral anoxia occurred as a direct consequence of anesthesia during the second trimester of gestation. Supporting documentation should detail the anoxic event, the anesthetic agent or procedure involved, and the gestational period.

• Ensure the anoxia is explicitly linked to anesthesia and not another cause.
• Verify the anoxic event occurred specifically during the second trimester (weeks 14-27).
• Sequence this code after the primary obstetric code indicating the pregnancy complication.
