R41.8Other symptoms and signs involving cognitive functions and awareness

R41.8 is the ICD-10-CM diagnosis code for other symptoms and signs involving cognitive functions and awareness. It belongs to category R41 (other symptoms and signs involving cognitive functions and awareness), 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.

Within R41, choose R41.8 (Other symptoms and signs involving cognitive functions and awareness) only when documentation doesn't support a more specific option: Disorientation, unspecified (R41.0), Anterograde amnesia (R41.1), retrograde amnesia (R41.2), other amnesia (R41.3), neurologic neglect syndrome (R41.4) and unspecified symptoms and signs involving cognitive functions and awareness (R41.9).

To report this condition, pick the subcode that matches the documentation: R41.81 (decline), R41.82 (unspecified), R41.83 (functioning), R41.84 (deficit), R41.85 (Anosognosia) and R41.89 (awareness).

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