About R87.61
R87.61 is the ICD-10-CM diagnosis code for abnormal cytological findings in specimens from cervix uteri. It belongs to category R87 (abnormal findings in specimens from female genital organs), block R83-R89 (abnormal findings on examination of other body fluids, substances and tissues, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.
Within R87.6 (abnormal cytological findings in specimens from female genital organs), R87.61 is specifically for abnormal cytological findings in specimens from cervix uteri. Related codes cover vagina (R87.62) and other female genital organs (R87.69).
To report this condition, pick the subcode that matches the documentation: R87.610 ((ASC-US)), R87.611 ((ASC-H)), R87.612 ((LGSIL)), R87.613 ((HGSIL)), R87.614 (cervix), R87.615 (cervix), R87.616 (zone), R87.618 (uteri) and 1 more.
Don't report R87.61 together with the conditions in its Excludes1 note: abnormal cytological findings in specimens from other female genital organs (R87.69), abnormal cytological findings in specimens from vagina (R87.62-), carcinoma in situ of cervix uteri (histologically confirmed) (D06.-), cervical intraepithelial neoplasia I [CIN I] (N87.0) and 4 more.
The conditions in its Excludes2 note aren't part of R87.61, but may be coded alongside it if the patient has both: cervical high risk human papillomavirus (HPV) DNA test positive (R87.810) and cervical low risk human papillomavirus (HPV) DNA test positive (R87.820).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
