F98.9 Diagnosis Code: Unspecified behavioral and emotional disorders with onset usually occurring in childhood and adolescence
The ICD-10 F98.9 diagnosis code designates Unspecified behavioral and emotional disorders with onset usually occurring in childhood and adolescence. This is meant to be used on a patient confirmed to have a behavioral or emotional condition that started back in their childhood or adolescence.
It’s part of the ICD-10 code group that includes ICD-10 codes for the following:
- Enuresis
- Encopresis
- Other feeding disorders
- Rumination disorder of infancy
- Pica of infancy
- Stereotyped movement disorders
- Adult onset fluency disorder
- Other behavioral and emotional disorders
Since this ICD-10 code has an unspecified label, you can only use it if you haven’t determined your patient's specific behavioral and/or emotional disorder(s).
Once you’ve determined the specific behavioral/emotional disorder, you need to pick a more specific ICD-10 code.
