R22 vs R90
R22 (Localized swelling, mass and lump of skin and subcutaneous tissue) compared with R90 (Abnormal findings on diagnostic imaging of central nervous system), 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. R22 carries an Excludes1 note covering R90: “abnormal findings on diagnostic imaging (R90-R93)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
