Clinical Classification
Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.
They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.
Disruptive, impulse-control and conduct disorders
CCSR Code: MBD008
Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Unsocial unaggress-unsp
ICD-9-CM: 312.10
Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.
Other conduct disorder

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:
- Harming or threatening themselves, other people or pets
- Damaging or destroying property
- Lying or stealing
- Not doing well in school, skipping school
- Early smoking, drinking or drug use
- Early sexual activity
- Frequent tantrums and arguments
- Consistent hostility toward authority figures
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.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
