About coding attention and concentration deficit
The ICD-10-CM code for attention and concentration deficit is R41.840 (Attention and concentration deficit). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R41.840.
Within R41.84 (other specified cognitive deficit), R41.840 is specifically for attention and concentration deficit. Related codes cover cognitive communication deficit (R41.841), Visuospatial deficit (R41.842), psychomotor deficit (R41.843) and frontal lobe and executive function deficit (R41.844).
Don't report R41.840 together with the conditions in its Excludes1 note: attention-deficit hyperactivity disorders (F90.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
