Bariatric surgery status comp pregnancy, first trimester

This code signifies a pregnant patient in her first trimester who has a history of bariatric surgery, and this surgical history is causing complications during the current pregnancy. These complications can include nutritional deficiencies, malabsorption issues, or other adverse effects directly attributable to the prior bariatric procedure.

Use this code when documentation clearly indicates that a patient's previous bariatric surgery is impacting her current first-trimester pregnancy. This applies to scenarios where the bariatric surgery is identified as a contributing factor to pregnancy-related issues, such as severe nausea and vomiting exacerbated by altered anatomy, or the need for specialized nutritional monitoring due to malabsorption.

• Always sequence this code after the primary obstetric code (e.g., O09.- for supervision of high-risk pregnancy).
• Ensure documentation specifies "complicating pregnancy" and the trimester. If no complication is noted, O99.84- is not appropriate.
• Do not confuse with codes for current bariatric surgery during pregnancy, which would be coded differently.
