Endo, nutritional and metab diseases comp preg, third tri

This code signifies the presence of an endocrine, nutritional, or metabolic disorder that is adversely affecting a pregnancy during the third trimester. These conditions can include, but are not limited to, thyroid disorders, diabetes (excluding gestational diabetes), obesity, or nutritional deficiencies, which are pre-existing or arise during pregnancy and impact maternal or fetal health.

Apply this code when documentation clearly indicates a pre-existing or newly diagnosed endocrine, nutritional, or metabolic disease is complicating a pregnancy that is currently in the third trimester. This requires physician documentation explicitly linking the condition as a complication of the pregnancy during this specific trimester.

• Always sequence this code after the primary code for the specific endocrine, nutritional, or metabolic condition (e.g., E05.90 for thyrotoxicosis).
• Do not use for gestational diabetes; refer to codes in the O24.4- category.
• Ensure the medical record specifies "third trimester" for accurate application of this trimester-specific code.
