What This Code Means
R87.7 is the ICD-10-CM diagnosis code for abnormal histological findings in specimens from female genital organs. Abnormal tissue findings from a biopsy or tissue sample taken from female genital organs, indicating unusual cellular structure or composition. R87.7 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering abnormal findings on examination of other body fluids, substances and tissues, without diagnosis (r83-r89).
R87.7 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This code is for histology (tissue examination) results, not cytology (cell examination); ensure the specimen type is correctly identified.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R87.7 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code is for histology (tissue examination) results, not cytology (cell examination); ensure the specimen type is correctly identified
