About the N87 Code Range
ICD-10 code N87 covers the classification of dysplasia of the cervix uteri, a condition where abnormal cells are found on the surface of the cervix. This section is used to identify and code varying degrees of cervical cell changes ranging from mild to moderate and unspecified dysplasia.
The codes include N87.0 for mild cervical dysplasia, often referred to as cervical intraepithelial neoplasia grade 1 or low grade cervical glandular intraepithelial neoplasia. Code N87.1 details moderate cervical dysplasia, corresponding to cervical intraepithelial neoplasia grade 2. Unspecified cervical dysplasia is coded under N87.9, which covers broader terms such as cervical atypism, hyperplasia, and various surgical margin findings related to intraepithelial neoplasia. Using the correct ICD-10 code for cervical dysplasia helps healthcare professionals accurately document the severity and specific diagnosis, aiding in patient care and medical record keeping.
