    ICD-10-CM Code For Dysplasia Of Cervix Uteri: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N87 includes cervical epithelial dysplasia diagnoses, covering mild, moderate, and severe intraepithelial neoplasia of the cervix uteri as well as unspecified dysplasia. These ICD-10-CM diagnosis codes are used to document abnormal cervical cellular changes detected on cytology or histology, capturing disease severity and lesion extent relevant to patient management. Accurate coding within the ICD-10-CM N87 group supports proper claim adjudication and complete clinical documentation and appropriate reimbursement.

    ICD-10-CM N87: Dysplasia Of Cervix Uteri Overview

    The ICD-10-CM N87 group represents cervical epithelial dysplasia, including mild, moderate, and severe intraepithelial neoplasia of the cervix uteri affecting the female reproductive system. These codes capture noninflammatory abnormal cellular changes of the cervix that may require surveillance or intervention. Accurate coding is important for clinical tracking, appropriate claim processing, and supporting medical necessity for diagnostic and therapeutic services.

    When to Use

    Use a code from this group when documentation indicates cervical epithelial dysplasia, with coding selected to reflect the stated grade or whether the dysplasia is unspecified. Select the specific code when pathology or clinical records specify mild, moderate, or severe intraepithelial neoplasia to accurately reflect disease severity.

    Typical Clinical Scenarios

    • A 24-year-old woman attends a routine well-woman visit after an abnormal Pap test showing high-grade squamous intraepithelial lesion (HSIL). Colposcopy with directed biopsy confirms moderate dysplasia (CIN 2) of the cervix; the visit documents the dysplastic lesion as the reason for planned excisional treatment. Typical codes: N87.1
    • A 38-year-old woman with a history of serial abnormal cervical cytology presents for follow-up surveillance; recent cervical biopsy demonstrates mild dysplasia (CIN 1) without evidence of invasive disease, and a conservative management plan with repeat cytology and colposcopy is arranged. Typical codes: N87.0
    • A 52-year-old perimenopausal woman presents with postcoital bleeding and a prior unknown Pap history; biopsy from colposcopy shows cervical epithelial dysplasia that is not specified as mild or moderate on the pathology report, and the clinician documents dysplasia of the cervix as a contributing diagnosis while evaluating for definitive treatment. Typical codes: N87.9
