Within R87.62 (abnormal cytological findings in specimens from vagina), R87.620 is specifically for atypical squamous cells of undetermined significance on cytologic smear of vagina (ASC-US). Related codes cover atypical squamous cells cannot exclude high grade squamous intraepithelial lesion on cytologic smear of vagina (ASC-H) (R87.621), low grade squamous intraepithelial lesion on cytologic smear of vagina (LGSIL) (R87.622), high grade squamous intraepithelial lesion on cytologic smear of vagina (HGSIL) (R87.623), cytologic evidence of malignancy on smear of vagina (R87.624), unsatisfactory cytologic smear of vagina (R87.625), other abnormal cytological findings on specimens from vagina (R87.628) and unspecified abnormal cytological findings in specimens from vagina (R87.629).
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 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 760 (Menstrual and Other Female Reproductive System Disorders with CC/MCC, relative weight 1.0129) and DRG 761 (Menstrual and Other Female Reproductive System Disorders without CC/MCC, relative weight 0.7041), in MDC 13 (Diseases and Disorders of the Female Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
