Unsp comp of anesthesia during pregnancy, third trimester

This code signifies an adverse event or undesirable outcome related to the administration of anesthesia during the third trimester of pregnancy, where the specific nature of the complication is not documented. It covers any unstated issue arising from anesthetic agents or techniques used for procedures or pain management in the late stages of gestation.

Apply this code when documentation clearly indicates an anesthesia-related complication occurred during the third trimester, but the provider has not specified the exact type of complication (e.g., "anesthesia complication during third trimester"). This code is appropriate when more specific codes for anesthesia complications are not supported by the clinical record.

• Always attempt to query the provider for a more specific diagnosis if the documentation is vague.
• Do not use this code if the complication is known and a more specific ICD-10-CM code exists (e.g., O29.2x for respiratory complications).
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the pregnancy or the procedure for which anesthesia was administered.
