Obesity complicating pregnancy, third trimester

This code signifies the presence of obesity in a pregnant patient during her third trimester, where the obesity is considered a complicating factor for the pregnancy. It indicates that the patient's elevated body mass index (BMI) is impacting the management or outcome of the current gestation.

Apply this code when a pregnant patient in her third trimester has a documented diagnosis of obesity that is noted by the provider as complicating the pregnancy. Documentation should clearly link the obesity to the pregnancy, such as "obesity complicating pregnancy" or "morbidly obese patient in third trimester with increased risk factors due to weight."

• Always sequence this code after the primary obstetric code (e.g., O80, O09.-).
• Ensure the medical record explicitly states the trimester of pregnancy.
• Do not use this code if obesity is merely noted but not documented as complicating the pregnancy.
