R44Other symptoms and signs involving general sensations and perceptions

R44 is the ICD-10-CM diagnosis code for other symptoms and signs involving general sensations and perceptions. It belongs to block R40-R46 (symptoms and signs involving cognition, perception, emotional state and behavior) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R44.0 (hallucinations), R44.1 (hallucinations), R44.2 (hallucinations), R44.3 (unspecified), R44.8 (perceptions) and R44.9 (perceptions).

Don't report R44 together with the conditions in its Excludes1 note: alcoholic hallucinations (F10.151, F10.251, F10.951), hallucinations in drug psychosis (F11-F19 with fifth to sixth characters 51), hallucinations in mood disorders with psychotic symptoms (F30.2, F31.5, F32.3, F33.3) and hallucinations in schizophrenia, schizotypal and delusional disorders (F20-F29).

The conditions in its Excludes2 note aren't part of R44, but may be coded alongside it if the patient has both: disturbances of skin sensation (R20.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
