About R87.618

R87.618 is the ICD-10-CM diagnosis code for other abnormal cytological findings on 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within R87.61, choose R87.618 (Other abnormal cytological findings on specimens from cervix uteri) only when documentation doesn't support a more specific option: atypical squamous cells of undetermined significance on cytologic smear of cervix (ASC-US) (R87.610), atypical squamous cells cannot exclude high grade squamous intraepithelial lesion on cytologic smear of cervix (ASC-H) (R87.611), low grade squamous intraepithelial lesion on cytologic smear of cervix (LGSIL) (R87.612), high grade squamous intraepithelial lesion on cytologic smear of cervix (HGSIL) (R87.613), cytologic evidence of malignancy on smear of cervix (R87.614), unsatisfactory cytologic smear of cervix (R87.615), Satisfactory cervical smear but lacking transformation zone (R87.616) and unspecified abnormal cytological findings in specimens from cervix uteri (R87.619).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 795 (Normal Newborn, relative weight 0.2022), DRG 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 795.4 (other nonspecific abnormal histological findings).
