Other hallucinations

This code signifies the presence of sensory perceptions that occur in the absence of an external stimulus, which are not otherwise specified as auditory, visual, or olfactory. It encompasses various types of hallucinations, such as tactile (e.g., feeling bugs crawling on skin) or gustatory (e.g., tasting something that isn't there), when a more specific code is not available.

Apply this code when documentation clearly indicates a patient is experiencing hallucinations that do not fit the criteria for auditory, visual, or olfactory types. This is appropriate for conditions like delirium, substance-induced psychosis, or certain neurological disorders where the specific hallucinatory modality is non-standard or unspecified. Ensure the medical record explicitly states "other hallucinations" or describes a type not covered by more specific R44 codes.

• Do not use this code if the hallucination type (auditory, visual, olfactory) is clearly documented; instead, use the more specific R44.0, R44.1, or R44.3.
• Always sequence this code after the definitive diagnosis for the underlying condition causing the hallucinations, if known.
• Avoid using this code for illusions, which are misinterpretations of real external stimuli, as these are distinct from hallucinations.
