Code Description

ICD-10 N93.9 is a billable code used to indicate a diagnosis of abnormal uterine and vaginal bleeding, unspecified.

Key Diagnostic Point:

Abnormal uterine and vaginal bleeding encompasses a range of conditions characterized by bleeding that deviates from the normal menstrual cycle. This can include heavy menstrual bleeding (menorrhagia), bleeding between periods (intermenstrual bleeding), or postmenopausal bleeding. The causes of abnormal bleeding can be multifactorial, including hormonal imbalances, structural abnormalities such as fibroids or polyps, infections, and malignancies. In the context of menstrual disorders, abnormal bleeding can significantly impact a woman's quality of life and may be associated with conditions like polycystic ovary syndrome (PCOS) or endometriosis. Menopausal disorders may also present with abnormal bleeding patterns as women transition through perimenopause to menopause. In cases of female infertility, abnormal bleeding can complicate the assessment of ovulatory function and overall reproductive health. Additionally, complications arising from artificial fertilization procedures may lead to abnormal bleeding, necessitating careful evaluation and management. Accurate diagnosis and treatment are essential to address the underlying causes and improve reproductive outcomes.
