Oth comp of anesthesia during pregnancy, second trimester

This code signifies any adverse event or physiological disturbance arising from anesthetic agents or techniques administered during the second trimester of pregnancy, not otherwise specified. These complications are directly attributable to the anesthesia and impact the pregnant patient.

Apply this code when documentation clearly indicates a complication directly related to anesthesia during the 14th to 27th week of gestation. Examples include unexpected hypotension, respiratory depression, or allergic reactions to anesthetic agents, where the cause is definitively linked to the anesthesia and not an underlying maternal condition or the pregnancy itself.

• Ensure documentation specifies the second trimester and explicitly links the complication to anesthesia.
• Do not use this code for complications of anesthesia during labor and delivery (O74.-) or the puerperium (O89.-).
• Always sequence this code after the primary obstetric code (e.g., the condition for which the anesthesia was administered).
