What are Abnormal Uterus Bleeding ICD-10-CM Codes?

Abnormal uterine bleeding refers to irregular or excessive bleeding from the female genital tract, particularly the uterus, outside of a normal menstrual cycle. Hormonal imbalances, structural abnormalities, or noninflammatory disorders of the female genital organs can cause this condition. Below are the most commonly used ICD-10-CM codes for abnormal uterine and vaginal bleeding:

  • N93.9 – Abnormal uterine and vaginal bleeding, unspecified
    Used when there is vaginal bleeding unspecified in origin or cause. This may involve contact bleeding, irregular menstruation, or bleeding not clearly linked to the menstrual cycle.
  • N92.4 – Excessive bleeding in the premenopausal period
    Applicable to frequent menstruation or excessive bleeding in women who have not yet reached menopause. This often indicates a perimenopausal disorder or other functional uterine condition.

Which Abnormal Uterus Bleeding ICD-10-CM Codes are billable?

Each of the ICD-10-CM codes listed above is billable and valid for clinical documentation and insurance claims involving abnormal uterine and vaginal bleeding:

  • N93.9 is used when there is abnormal bleeding without a definitive diagnosis, covering a wide range of uterine and vaginal bleeding disorders.
  • N92.4 applies to patients with excessive bleeding during the premenopausal period, which may suggest a disorder of the female genital organs.

Clinical information

Abnormal uterine bleeding (AUB) is defined as bleeding that occurs outside of normal menstruation patterns. This can involve postcoital and contact bleeding, spotting between periods, or bleeding after menopause. Here are key clinical notes:

  • AUB may occur due to functional uterine disorders, hormonal fluctuations, female infertility, or structural issues in the female genital or genitourinary system.
  • Symptoms can include frequent, heavy, or prolonged bleeding, which may require evaluation for diseases such as fibroids, polyps, or cancer.
  • Management varies based on age, reproductive goals, and severity. Treatments can include hormonal therapy, surgical interventions, or watchful waiting in milder cases.

These abnormal uterus bleeding ICD-10 codes are particularly important for diagnosing and treating issues not caused by pregnancy or infection but still significantly affecting the patient's quality of life. They help document other conditions of the female genital tract, especially when linked to excessive and frequent menstruation, vaginal bleeding, or unspecified uterine symptoms.

By using accurate ICD-10-CM codes, providers can ensure proper diagnosis, support correct billing, and offer appropriate care for women experiencing abnormal uterine and vaginal bleeding.
