R41Other symptoms and signs involving cognitive functions and awareness

R41 is the ICD-10-CM diagnosis code for other symptoms and signs involving cognitive functions and awareness. 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R41.0 (unspecified), R41.1 (amnesia), R41.2 (amnesia), R41.3 (amnesia), R41.4 (syndrome), R41.8 (awareness) and R41.9 (awareness).

Don't report R41 together with the conditions in its Excludes1 note: dissociative [conversion] disorders (F44.-) and mild cognitive impairment of uncertain or unknown etiology (G31.84).

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