Unsp comp of anesthesia during pregnancy, second trimester

This code signifies an adverse event or undesirable outcome related to anesthesia administration that occurred during the second trimester of a pregnancy, where the specific nature of the complication is not documented. It indicates a general anesthetic complication without further detail regarding its type or manifestation.

This code is appropriate when documentation clearly states an anesthesia-related complication during the second trimester of pregnancy, but the physician's notes lack specificity regarding the exact type of complication (e.g., "anesthesia complication during pregnancy, second trimester"). It should be used when no more specific code for an anesthesia complication can be assigned.

• Always attempt to query for a more specific anesthesia complication if documentation is vague.
• Ensure the complication explicitly occurred during the second trimester of pregnancy.
• Do not use if the complication is known and a more specific O29.x code is available.
