Oth pulmonary comp of anesth during preg, second trimester

This code signifies a non-specific pulmonary complication arising from anesthesia administered during the second trimester of pregnancy. It covers various adverse respiratory events, such as aspiration pneumonitis, atelectasis, or bronchospasm, that are directly attributable to the anesthetic agent or technique.

Use this code when the patient experiences a pulmonary complication during the second trimester of pregnancy that is clearly documented as a direct result of anesthesia. This applies to complications occurring during or immediately following an anesthetic procedure, such as for surgery or pain management. Documentation should explicitly link the pulmonary issue to the anesthesia.

• Ensure documentation specifies "second trimester" to support this code.
• Do not use if a more specific pulmonary complication code related to anesthesia is available (e.g., O29.01x for aspiration pneumonitis).
• Always sequence this code after the primary obstetric code and the code for the specific pulmonary complication, if known.
