F20 vs R44

F20 (Schizophrenia) compared with R44 (Other symptoms and signs involving general sensations and perceptions), 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. R44 carries an Excludes1 note covering F20: “hallucinations in schizophrenia, schizotypal and delusional disorders (F20-F29)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
