R41.84Other specified cognitive deficit

R41.84 is the ICD-10-CM diagnosis code for other specified cognitive deficit. 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 5 subcodes must be used instead.

Within R41.8, choose R41.84 (Other specified cognitive deficit) only when documentation doesn't support a more specific option: age-related cognitive decline (R41.81), Altered mental status, unspecified (R41.82), borderline intellectual functioning (R41.83), Anosognosia (R41.85) and other symptoms and signs involving cognitive functions and awareness (R41.89).

To report this condition, pick the subcode that matches the documentation: R41.840 (deficit), R41.841 (deficit), R41.842 (deficit), R41.843 (deficit) and R41.844 (deficit).

Don't report R41.84 together with the conditions in its Excludes1 note: cognitive deficits as sequelae of cerebrovascular disease (I69.01-, I69.11-, I69.21-, I69.31-, I69.81-, I69.91-).

Code first the underlying condition, if known, such as: schizophrenia (F20.-).

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