Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Excessive uterine bleeding during MENSTRUATION.
Menstruation

About the N93 Code Range
ICD-10 code N93 and its specific subcodes classify various types of abnormal uterine and vaginal bleeding that do not fall under more common menstrual disorders. These codes are used to identify unusual bleeding patterns such as bleeding after intercourse, in young children before puberty, or unspecified abnormal bleeding.
N93.0 covers postcoital and contact bleeding, often referred to by terms like "postcoital bleeding" or "postmenopausal bleeding," helping clinicians document bleeding related to sexual activity or menopausal status. N93.1 is specific for pre-pubertal vaginal bleeding, indicating bleeding in girls who have not yet begun menstruation. The N93.8 category includes various specified abnormal uterine or vaginal bleeding causes such as bleeding due to uterine fibroids, endometrial disorders, or clot passage, with synonyms including "menorrhagia," "mid-cycle bleeding," and "anovular menstruation." Lastly, N93.9 is used for unspecified abnormal uterine and vaginal bleeding, capturing cases without a precise diagnosis and covering terms like "heavy vaginal bleeding" and "non-menstrual vaginal bleeding." These ICD-10 codes support accurate coding for less common or unclear abnormal bleeding scenarios encountered in gynecologic practice.
