Cardiac failure due to anesth during preg, unsp trimester

This code signifies a diagnosis of heart failure that develops as a direct consequence of anesthesia administered during pregnancy. It indicates that the specific trimester of pregnancy when this complication occurred is not documented or is unknown. This is a serious obstetric complication requiring immediate medical attention.

Apply this code when documentation clearly links the onset of cardiac failure to anesthetic agents or procedures performed during pregnancy, and the specific trimester is not specified. This diagnosis should be supported by physician notes detailing the temporal relationship between anesthesia and the development of heart failure symptoms and signs.

• Always attempt to identify the specific trimester if possible, as more specific codes exist.
• Ensure documentation explicitly states "due to anesthesia" to differentiate from pre-existing cardiac conditions or other causes of heart failure in pregnancy.
• Sequence this code as a secondary diagnosis following the primary obstetric code for the pregnancy.
