About coding attention deficiency
The ICD-10-CM code for attention deficiency is F98.8 (Other specified behavioral and emotional disorders with onset usually occurring in childhood and adolescence).
Within F98, choose F98.8 (Other specified behavioral and emotional disorders with onset usually occurring in childhood and adolescence) only when documentation doesn't support a more specific option: enuresis not due to a substance or known physiological condition (F98.0), Encopresis not due to a substance or known physiological condition (F98.1), other feeding disorders of infancy and childhood (F98.2), Pica of infancy and childhood (F98.3), Stereotyped movement disorders (F98.4), adult onset fluency disorder (F98.5) and unspecified behavioral and emotional disorders with onset usually occurring in childhood and adolescence (F98.9).
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.
