Oth comp of anesthesia during pregnancy, third trimester

This code signifies any adverse event or physiological disturbance arising from the administration of anesthesia during the third trimester of pregnancy, excluding those specifically classified elsewhere. These complications are directly attributable to the anesthetic agent or technique and manifest during the final three months of gestation.

Apply this code when documentation clearly links a complication to anesthesia administered during the third trimester, such as an unexpected severe allergic reaction, prolonged hypotension, or respiratory depression not otherwise specified. The medical record must explicitly state the complication occurred during the third trimester and was a direct result of anesthesia.

• Ensure the documentation specifies "third trimester" and clearly links the complication to anesthesia.
• Do not use this code for complications of anesthesia during labor and delivery (O74.-) or the puerperium (O89.-).
• Always code the specific complication first, if known, followed by this code as a secondary diagnosis.
