N89 vs R87.7
N89 (Other noninflammatory disorders of vagina) compared with R87.7 (Abnormal histological findings in specimens from female genital organs), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. R87.7 carries an Excludes1 note covering N89: “dysplasia (mild) (moderate) of vagina (histologically confirmed) (N89.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
