Cardiac failure due to anesth during preg, third trimester

This code signifies the development of cardiac failure in a pregnant patient during her third trimester, where the heart's inability to pump sufficient blood is directly attributable to the administration of anesthesia. This represents a serious adverse event related to anesthetic management during late pregnancy.

Apply this code when documentation clearly links the onset or exacerbation of cardiac failure to anesthesia given during the third trimester of pregnancy. This typically occurs in scenarios such as surgical procedures (e.g., C-section) or pain management interventions requiring anesthesia. Supporting documentation should include physician notes detailing the cardiac event, the timing of anesthesia administration, and a causal relationship between the two.

• Always sequence this code after the primary obstetric code (e.g., O80-O82 for delivery, or other O codes for complications of pregnancy).
• Ensure the documentation explicitly states "cardiac failure" and clearly implicates "anesthesia" as the cause.
• Do not use this code for cardiac failure pre-existing the anesthesia or unrelated to its administration.
