Endo, nutritional and metab diseases comp preg, second tri

This code signifies a pre-existing or new endocrine, nutritional, or metabolic disorder that is adversely affecting a pregnancy during the second trimester. This includes conditions such as gestational diabetes, thyroid disorders, or nutritional deficiencies that are impacting maternal or fetal health.

Apply this code when a pregnant patient in her second trimester is diagnosed with an endocrine, nutritional, or metabolic condition that complicates her pregnancy. Documentation should clearly state the specific disorder and its impact on the pregnancy, along with the gestational age or trimester.

• Always sequence this code after the primary obstetric code (e.g., O09.- for supervision of high-risk pregnancy).
• Ensure the medical record explicitly states "second trimester" or provides gestational weeks falling within the second trimester (typically weeks 14-27).
• Do not use for conditions that are not complicating the pregnancy; use a code from the endocrine, nutritional, and metabolic chapter (E00-E89) instead.
