Other symptoms and signs involving cognitive functions and awareness (R41) ICD-10-CM
The R41 code range covers other symptoms and signs involving cognitive functions and awareness with 19 ICD-10-CM diagnosis codes. 16 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the R41 range.
Akinetic Mutism
A syndrome characterized by a silent and inert state without voluntary motor activity despite preserved sensorimotor pathways and vigilance. Bilateral FRONTAL LOBE dysfunction involving the anterior cingulate gyrus and related brain injuries are associated with this condition. This may result in impaired abilities to communicate and initiate motor activities. (From Adams et al., Principles of Neurology, 6th ed, p348; Fortschr Neurol Psychiatr 1995 Feb;63(2):59-67)
Altered Mental Status
A change to an individual's judgment, orientation (to place, time, and self), intellectual functioning, or mood from their baseline.
Amnesia
Pathologic partial or complete loss of the ability to recall past experiences (AMNESIA, RETROGRADE) or to form new memories (AMNESIA, ANTEROGRADE). This condition may be of organic or psychologic origin. Organic forms of amnesia are usually associated with dysfunction of the DIENCEPHALON or HIPPOCAMPUS. (From Adams et al., Principles of Neurology, 6th ed, pp426-7)
Amnesia, Anterograde
Loss of the ability to form new memories beyond a certain point in time. This condition may be organic or psychogenic in origin. Organically induced anterograde amnesia may follow CRANIOCEREBRAL TRAUMA; SEIZURES; ANOXIA; and other conditions which adversely affect neural structures associated with memory formation (e.g., the HIPPOCAMPUS; FORNIX (BRAIN); MAMMILLARY BODIES; and ANTERIOR THALAMIC NUCLEI). (From Memory 1997 Jan-Mar;5(1-2):49-71)
Amnesia, Retrograde
Loss of the ability to recall information that had been previously encoded in memory prior to a specified or approximate point in time. This process may be organic or psychogenic in origin. Organic forms may be associated with CRANIOCEREBRAL TRAUMA; CEREBROVASCULAR ACCIDENTS; SEIZURES; DEMENTIA; and a wide variety of other conditions that impair cerebral function. (From Adams et al., Principles of Neurology, 6th ed, pp426-9)
Anosognosia
A condition in which a person who suffers illness or disability seems unaware of or denies the existence of the illness or disability.
Confusion
A mental state characterized by bewilderment, emotional disturbance, lack of clear thinking, and perceptual disorientation.
Delirium
A disorder characterized by CONFUSION; inattentiveness; disorientation; ILLUSIONS; HALLUCINATIONS; agitation; and in some instances autonomic nervous system overactivity. It may result from toxic/metabolic conditions or structural brain lesions. (From Adams et al., Principles of Neurology, 6th ed, pp411-2)
About the R41 Code Range
These symptoms involve thinking and awareness. The category includes disorientation, amnesia (memory loss), and other changes in cognitive function.
R41.0 identifies disorientation. R41.1, R41.2, and R41.3 separate named types of amnesia. R41.8 branches into other symptoms, including age-related cognitive decline and altered mental status. Within that branch, R41.84 divides specified cognitive deficits by function, such as attention, communication, and visuospatial ability. R41.9 identifies unspecified symptoms involving cognitive functions and awareness.
