Cardiac failure due to anesth during preg, second trimester

This code signifies a diagnosis of cardiac decompensation or pump failure occurring as a direct consequence of anesthetic agents administered during the second trimester of pregnancy. It indicates a severe adverse reaction to anesthesia impacting the heart's ability to effectively circulate blood.

Apply this code when a pregnant patient in her second trimester experiences new-onset or exacerbated heart failure directly attributable to anesthesia. Documentation should clearly link the cardiac event to the anesthetic administration, specifying the trimester and the nature of the cardiac failure.

• Requires physician documentation explicitly stating "cardiac failure due to anesthesia" and the "second trimester."
• Do not use for cardiac arrest; this code is specific to cardiac failure.
• Sequence this code after the primary obstetric code (e.g., O09.- for supervision of high-risk pregnancy, if applicable) or as the principal diagnosis if the cardiac failure is the reason for the encounter.
