Cerebral anoxia due to anesth during preg, first trimester

This code signifies a condition where a pregnant patient in her first trimester experiences a lack of oxygen to the brain (cerebral anoxia) specifically caused by the administration of anesthesia. This is a serious complication that can lead to neurological damage.

This code is appropriate when documentation clearly links cerebral anoxia to an anesthetic event occurring during the first trimester of pregnancy. It should be used when the anoxia is a direct consequence of the anesthesia, not from other causes.

• Ensure documentation explicitly states the anoxia is "due to anesthesia" and specifies the "first trimester."
• Do not use this code if the anoxia is due to other obstetric complications or non-anesthesia related events.
• Sequence this code as a primary diagnosis when it is the main reason for the encounter, followed by codes for any resulting neurological deficits.
