F82 vs R26
F82 (Specific developmental disorder of motor function) compared with R26 (Abnormalities of gait and mobility), 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. F82 carries an Excludes1 note covering R26: “abnormalities of gait and mobility (R26.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
