F29 vs R44
F29 (Unspecified psychosis not due to a substance or known physiological condition) 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 F29: “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).
