N85 vs N86
N85 (Other noninflammatory disorders of uterus, except cervix) compared with N86 (Erosion and ectropion of cervix uteri), 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. N85 carries an Excludes1 note covering N86: “noninflammatory disorders of cervix, except malposition (N86-N88)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
