About coding Knowledge acquisition disability
The ICD-10-CM code for Knowledge acquisition disability is F81.9 (Developmental disorder of scholastic skills, unspecified).
Within F81, choose F81.9 (Developmental disorder of scholastic skills, unspecified) only when documentation doesn't support a more specific option: specific reading disorder (F81.0), Mathematics disorder (F81.2) and other developmental disorders of scholastic skills (F81.8).
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 886 (Behavioral and Developmental Disorders, relative weight 1.8678), 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.
