F80.0 vs R48.2
F80.0 (Phonological disorder) compared with R48.2 (Apraxia), 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. F80.0 carries an Excludes1 note covering R48.2: “speech articulation impairment due to apraxia (R48.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
