Pregnancy related exhaustion and fatigue, first trimester

This code signifies significant and persistent tiredness or lack of energy experienced by a pregnant patient during her first trimester, directly attributable to the physiological changes of pregnancy. It represents a common, non-pathological symptom that impacts daily functioning.

Assign this code when documentation explicitly states "pregnancy-related exhaustion" or "fatigue due to pregnancy" occurring in the first trimester. This code is appropriate for patients presenting with debilitating fatigue not otherwise explained by anemia, thyroid dysfunction, or other medical conditions.

• Ensure documentation specifies "first trimester" for accurate code assignment.
• Do not use this code if the fatigue is due to an underlying medical condition; code the specific condition instead.
• This code is typically a secondary diagnosis, following the primary code for the pregnancy itself (e.g., Z3A.00 for unspecified weeks of gestation).
