Cardiac failure due to anesth during preg, first trimester

This code signifies the development of cardiac failure in a pregnant patient during her first trimester, directly attributable to the administration of anesthesia. This represents a serious adverse event where the heart's ability to pump blood effectively is compromised due to anesthetic agents.

Apply this code when documentation clearly links the onset of cardiac failure to anesthesia administered during the first trimester of pregnancy. This typically occurs in scenarios such as surgical procedures or pain management interventions requiring anesthesia. Supporting documentation should include details of the anesthetic agent, the timing of its administration, and the subsequent diagnosis of cardiac failure.

• Ensure the documentation explicitly states a causal link between anesthesia and cardiac failure.
• Verify the trimester of pregnancy; this code is specific to the first trimester.
• Sequence this code as a secondary diagnosis following the code for the underlying reason for anesthesia, if applicable.
