Other specified irregular menstruation

This code represents menstrual irregularities that do not fit into more specific categories of abnormal uterine bleeding, such as menorrhagia, metrorrhagia, or polymenorrhea. It encompasses various patterns of irregular menstruation that are explicitly documented as "other specified" by the provider, indicating a deviation from the normal menstrual cycle without a more precise diagnostic term.

This code is appropriate when the physician's documentation clearly states an irregular menstrual pattern that doesn't align with more specific ICD-10-CM codes for menstrual disorders but is still clinically defined. Examples include documented "irregular periods, unspecified type," "unpredictable menstrual cycles," or "menstrual dysfunction, not otherwise classified." Documentation should specify the irregular nature of the bleeding.

• Do not use this code if a more specific code for abnormal uterine bleeding (e.g., N92.0-N92.4, N92.6) can be assigned based on documentation.
• Ensure the medical record explicitly states "other specified irregular menstruation" or provides a description that clearly falls into this "other specified" category.
• Always review for underlying causes of irregular menstruation (e.g., endocrine disorders, uterine pathology) and code them additionally if documented.
