F93.0Separation anxiety disorder of childhood

F93.0 is the ICD-10-CM diagnosis code for separation anxiety disorder of childhood. It belongs to category F93 (emotional disorders with onset specific to childhood), 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 F93 (emotional disorders with onset specific to childhood), F93.0 is specifically for separation anxiety disorder of childhood. Related codes cover other childhood emotional disorders (F93.8) and childhood emotional disorder, unspecified (F93.9).

The conditions in its Excludes2 note aren't part of F93.0, but may be coded alongside it if the patient has both: mood [affective] disorders (F30-F39), nonpsychotic mental disorders (F40-F48), phobic anxiety disorder of childhood (F40.8) and social phobia (F40.1).

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 882 (Neuroses Except Depressive, relative weight 0.9952), 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 309.21 (separation anxiety disorder).
