About N87
N87 is the ICD-10-CM diagnosis code for dysplasia of cervix uteri. It belongs to block N80-N98 (noninflammatory disorders of female genital tract) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: N87.0 (dysplasia), N87.1 (dysplasia) and N87.9 (unspecified).
Don't report N87 together with the conditions in its Excludes1 note: abnormal results from cervical cytologic examination without histologic confirmation (R87.61-), carcinoma in situ of cervix uteri (D06.-), cervical intraepithelial neoplasia III [CIN III] (D06.-), HGSIL of cervix (R87.613) and 1 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
