Absence of menstruation

This code signifies the cessation or absence of menstrual periods in a female. It encompasses both primary amenorrhea (menstruation never started) and secondary amenorrhea (menstruation started but later stopped). This condition can be a symptom of various underlying physiological or pathological processes.

Use this code when documentation clearly indicates a patient is experiencing amenorrhea, whether primary or secondary. This code is appropriate for initial evaluations, follow-up visits, and when amenorrhea is the primary reason for the encounter. Supporting documentation should include patient history regarding menstrual cycles and physician assessment.

• Always code the underlying cause of amenorrhea if known and documented (e.g., polycystic ovarian syndrome, pituitary disorders).
• Distinguish between primary and secondary amenorrhea if specified in the documentation, although this code covers both.
• Do not use this code for normal physiological absence of menses, such as during pregnancy or post-menopause, unless specifically noted as abnormal.
