R90.0 vs R93.0
R90.0 (Intracranial space-occupying lesion found on diagnostic imaging of central nervous system) compared with R93.0 (Abnormal findings on diagnostic imaging of skull and head, not elsewhere classified), 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. R93.0 carries an Excludes1 note covering R90.0: “intracranial space-occupying lesion found on diagnostic imaging (R90.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
