About F98.8
F98.8 is the ICD-10-CM diagnosis code for other specified behavioral and emotional disorders with onset usually occurring in childhood and adolescence. It belongs to category F98 (other behavioral and emotional disorders with onset usually occurring in childhood and adolescence), block F90-F98 (behavioral and emotional disorders with onset usually occurring in childhood and adolescence) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 313.89 (other emotional disturbances of childhood or adolescence).
