Oth pulmonary comp of anesth during preg, first trimester

This code signifies any non-specific pulmonary complication arising from anesthesia administered during the first trimester of pregnancy. This includes adverse respiratory events such as atelectasis, aspiration pneumonitis, or bronchospasm that are directly attributable to the anesthetic agent or procedure, excluding those with more specific ICD-10-CM codes.

Use this code when documentation clearly links a pulmonary complication to anesthesia during the first trimester of pregnancy, and a more specific code for the complication (e.g., O29.011 for aspiration pneumonitis) is not available or appropriate. This code is applicable when the specific nature of the pulmonary complication is not fully elucidated but is confirmed to be anesthesia-related.

• Always sequence this code after the primary obstetric code (e.g., O09.- for supervision of high-risk pregnancy).
• Ensure documentation explicitly states the pulmonary complication is due to anesthesia and occurred during the first trimester.
• Differentiate from O29.092 (second trimester) and O29.093 (third trimester) based on the gestational period.
