Endo, nutritional and metab diseases comp preg, first tri

This code signifies a pre-existing or newly diagnosed endocrine, nutritional, or metabolic disorder that is adversely affecting a pregnancy during the first trimester. This includes conditions such as diabetes mellitus, thyroid disorders, or nutritional deficiencies that pose a risk to either the mother or the fetus. The complication arises directly from the interplay between the underlying disorder and the physiological changes of early pregnancy.

Apply this code when documentation clearly indicates an endocrine, nutritional, or metabolic disease is complicating a pregnancy that is currently in its first trimester. This is appropriate for conditions like gestational diabetes diagnosed early, pre-existing type 1 or type 2 diabetes, or hyperthyroidism impacting the pregnancy during the initial 14 weeks. Supporting documentation should specify both the complicating condition and the trimester.

• Always sequence the code for the specific endocrine, nutritional, or metabolic condition (e.g., E10.9, E05.90) as a secondary diagnosis.
• Ensure the medical record explicitly states the pregnancy is in the first trimester; otherwise, a different trimester-specific code should be used.
• Do not use this code for conditions that are incidental to pregnancy and not directly complicating it.
