About coding executive function deficit
The ICD-10-CM code for executive function deficit is R41.844 (Frontal lobe and executive function 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 R41.844.
Within R41.84 (other specified cognitive deficit), R41.844 is specifically for frontal lobe and executive function deficit. Related codes cover attention and concentration deficit (R41.840), cognitive communication deficit (R41.841), Visuospatial deficit (R41.842) and psychomotor deficit (R41.843).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 884 (Organic Disturbances and Intellectual Disability, relative weight 1.6001), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
