F98.9 is a billable ICD-10 code used to specify a medical diagnosis of unspecified behavioral and emotional disorders with onset usually occurring in childhood and adolescence. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

Unspecified diagnosis codes like F98.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Patient Education


Child Behavior Disorders

All kids misbehave some times. And some may have temporary behavior problems due to stress. For example, the birth of a sibling, a divorce, or a death in the family may cause a child to act out. Behavior disorders are more serious. They involve a pattern of hostile, aggressive, or disruptive behaviors for more than 6 months. The behavior is also not appropriate for the child's age.

Warning signs can include:

If you see signs of a problem, ask for help. Poor choices can become habits. Kids who have behavior problems are at higher risk for school failure, mental health problems, and even suicide. Classes or family therapy may help parents learn to set and enforce limits. Talk therapy and behavior therapy for your child can also help.
