What This Code Means
F94.1 is the ICD-10-CM diagnosis code for reactive attachment disorder of childhood. A disorder in young children characterized by minimal emotional responsiveness, limited social interaction, and reduced comfort-seeking behavior toward caregivers, typically resulting from severe neglect or deprivation. F94.1 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering behavioral and emotional disorders with onset usually occurring in childhood and adolescence (f90-f98).
F94.1 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Document evidence of inadequate care, neglect, or deprivation in the child's history.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for F94.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
