F91 codes support conduct disorder documentation
The F91 ICD-10 code family is used for conduct disorders, including conduct disorder confined to family context, childhood-onset type, adolescent-onset type, other conduct disorders, and unspecified conduct disorder. These codes help describe clinical presentations involving repeated behavioral patterns that may violate rules, expectations, or the rights of others.
This guide is for documentation support. It does not assign a diagnosis, replace diagnostic assessment, or determine medical necessity. Diagnosis selection remains the clinician’s responsibility. A therapist, counselor, psychologist, psychiatrist, social worker, or other qualified behavioral health professional should select the code that best matches the client’s presentation, clinical history, assessment findings, and payer or organizational requirements.
For documentation, the goal is not just to list an ICD-10 code. The clinical record should show why the diagnosis is being addressed in treatment, how symptoms affect functioning, what interventions were provided, how the client responded, and what will happen next.
Common F91 ICD-10 codes clinicians may document
The F91 family includes several related codes. Clinicians should verify the current code set used by their organization or payer before finalizing a diagnosis in the record.
- F91.0: Conduct disorder confined to family context
- F91.1: Conduct disorder, childhood-onset type
- F91.2: Conduct disorder, adolescent-onset type
- F91.3: Oppositional defiant disorder
Additional related options may include F91.8 for other conduct disorders and F91.9 for conduct disorder, unspecified. These codes may appear in documentation when the available clinical information does not support a more specific code, or when the presentation does not fit another listed option.
Code specificity matters because it helps connect assessment findings, symptoms, treatment goals, and interventions. For example, documentation for a youth whose disruptive behavior occurs primarily at home may look different from documentation for a youth whose behavior occurs across home, school, peer, and community settings.
How F91.0 differs from the broader F91 family
F91.0 refers to conduct disorder confined to family context. In practical documentation terms, this means the clinical record should clearly describe behavior patterns that are primarily reported or observed in the family setting. That may include conflict with caregivers, aggression toward siblings, property damage at home, repeated violation of household rules, or other family-based behavioral concerns.
The phrase “confined to family context” should not be treated as a shortcut. If a clinician documents F91.0, the note should support why the family context is central to the case. For example, a progress note may reference caregiver reports, family session observations, home routines, sibling interactions, safety planning, or parent management strategies.
If similar behaviors are also occurring at school, in the community, online, or with peers, the clinician may need to reassess whether another code better reflects the presentation. AutoNotes can help organize the note draft around the details you enter, but the clinician remains responsible for reviewing the record and choosing the appropriate diagnosis.
Clinical details that strengthen F91 documentation
Strong conduct disorder documentation is specific. Instead of writing “client had behavior problems,” the note should describe what happened, where it happened, how often it occurs, who was affected, and how it relates to treatment goals.
Helpful details may include:
- Behavior description: aggression, threats, property damage, deceitfulness, serious rule violations, or conflict with caregivers.
- Context: home, school, community, peer group, sibling interactions, or family routines.
- Frequency and duration: how often behaviors occur and how long the pattern has been present.
- Functional impact: family disruption, school discipline, safety concerns, legal involvement, or strained relationships.
Documentation should also reflect the clinician’s observations when available. In family therapy, this may include how the client responds to limits, communicates with caregivers, accepts redirection, or escalates during conflict. In individual therapy, it may include insight, impulse control, emotional regulation, accountability, and willingness to practice replacement behaviors.
Collateral information can be clinically useful when appropriate and authorized. Caregiver reports, school communication, prior evaluations, crisis records, and treatment history may help clarify the pattern of behavior. The note should identify the source of information rather than presenting collateral reports as direct observation.
Assessment documentation for conduct-related presentations
Assessment notes for F91-related diagnoses often need more detail than a routine progress note. The clinician may be documenting presenting concerns, history, risk factors, strengths, family context, school functioning, prior services, and treatment recommendations.
A clear assessment section may address the following areas:
- Presenting problem: the specific conduct-related behaviors that led to referral or treatment.
- Onset and course: when symptoms began and whether they have changed over time.
- Settings affected: whether concerns occur at home only or across multiple environments.
- Risk and safety: threats, aggression, access to weapons, self-harm concerns, victimization, or unsafe supervision issues.
The assessment should also include relevant strengths. A youth may have a supportive caregiver, positive response to structured routines, interest in sports, connection with a mentor, or ability to de-escalate when given space. These details can guide treatment planning and avoid a record that only lists problem behaviors.
For differential diagnosis, clinicians may consider whether symptoms are better explained by trauma exposure, mood symptoms, substance use, neurodevelopmental concerns, family stress, grief, anxiety, or environmental instability. The note does not need to over-explain every possibility, but it should show the clinical reasoning that supports the diagnosis being used.
Progress note elements for F91 treatment sessions
Progress notes should connect the session content to the diagnosis and treatment plan. A strong note usually includes the session focus, interventions, client response, progress toward goals, and next steps.
For a conduct disorder-related session, interventions may include parent management strategies, problem-solving skills, anger regulation, communication practice, safety planning, impulse-control work, motivational interviewing, family role clarification, or coordination with school staff when clinically appropriate.
Client response should be concrete. Rather than “client participated,” the note might state that the client identified two triggers for aggressive outbursts, practiced a time-out plan with caregiver support, denied intent to harm a sibling, or became guarded when discussing restitution for property damage.
Example SOAP note for F91.0 documentation
The example below is for structure only. Clinicians should edit any note to match the actual session, diagnosis, client presentation, and documentation standards.
Date: [Date]
Client: [Client Initials or ID]
Diagnosis: F91.0 - Conduct disorder confined to family context
Service: Family therapy
S: Caregiver reported two verbal altercations between client and sibling during evening routines. Client stated, “I get mad when everyone blames me,” and denied current intent to harm self or others.
O: Client was alert and oriented. Affect was irritable at the start of session but became calmer with redirection. Client interrupted caregiver several times, then practiced waiting to respond during structured communication exercise.
A: Session focused on conflict patterns within the home and progress toward treatment goal of reducing aggressive responses during family disagreements. Client showed partial insight into triggers and was able to identify one replacement behavior. Caregiver demonstrated use of clear limit-setting language during role-play.
P: Continue family therapy next week. Client will practice taking a five-minute break before responding during sibling conflict. Caregiver will track incidents, triggers, and use of replacement behavior.This note supports the F91.0 context by naming the family setting, describing behavior within home routines, documenting the intervention, and connecting the plan to measurable behavior change.
Treatment plan considerations for F91-related diagnoses
Treatment planning should translate the diagnosis into measurable goals and practical interventions. For conduct-related concerns, goals often focus on reducing aggressive or rule-violating behaviors, improving emotional regulation, strengthening family communication, increasing accountability, and improving functioning at home or school.
A treatment plan might include a goal such as: “Client will reduce aggressive responses during family conflict from four times per week to one time per week over the next 12 weeks, based on caregiver report and client self-monitoring.” This is more useful than “Client will behave better,” because it gives the clinician and family a clearer way to monitor change.
Common objectives may include:
- Client will identify three triggers for escalation during family conflict.
- Client will practice two coping strategies before responding aggressively.
- Caregiver will use consistent consequences and reinforcement strategies.
- Family will complete one structured communication exercise each week.
Interventions should match the client’s age, developmental level, culture, family system, and risk profile. For some clients, individual skill-building may be central. For others, family therapy, caregiver coaching, school coordination, or psychiatric evaluation may be clinically appropriate.
Risk, safety, and collateral information in conduct disorder notes
Conduct-related documentation may involve safety concerns. If there are threats, physical aggression, cruelty to animals, weapon access, fire-setting, self-harm concerns, exploitation, abuse, or serious property destruction, the note should reflect assessment and planning within the clinician’s role and setting.
Risk documentation may include the client’s statements, caregiver concerns, observed behavior, protective factors, supervision plan, crisis resources provided, mandated reporting actions when applicable, and referrals or coordination. The level of detail should match the clinical situation. A routine session about arguing with a caregiver will not require the same risk documentation as a session involving threats with a weapon.
Collateral documentation should be clear about who provided the information. For example: “Caregiver reported client left home without permission on two occasions this week,” or “School counselor reported one suspension for fighting, with signed release on file.” This helps separate direct clinical observation from third-party report.
How AutoNotes supports F91 documentation without assigning diagnoses
AutoNotes helps clinicians create structured, editable progress note drafts from session details. For F91-related cases, that can mean organizing information about behaviors, family context, interventions, client response, treatment goals, and follow-up plans into a cleaner draft.
AutoNotes does not choose the diagnosis for you. The clinician reviews the client’s presentation, selects the appropriate ICD-10 code, edits the note, and finalizes the clinical record. This keeps clinical judgment where it belongs: with the provider.
For behavioral health professionals who document conduct-related treatment, AutoNotes can support:
- SOAP, DAP, intake, assessment, and treatment plan drafts
- More consistent documentation of interventions and client response
- Service-specific templates for individual, family, group, and assessment sessions
- Faster movement from session details to an editable clinical note
This can be especially helpful after a full schedule of sessions, when remembering the exact wording for interventions, progress toward goals, and next steps can take extra time. The clinician still reviews every section and adjusts the language to match the actual care provided.
Practical checklist before finalizing an F91 note
Before signing a note that includes an F91 code, clinicians can review a short checklist to make sure the record supports the session and treatment plan.
- Does the note describe specific behaviors rather than broad labels?
- Does it identify the setting, such as family context, school, peers, or community?
- Does it connect interventions to treatment goals?
- Does it document client response and next steps?
If the note includes caregiver or school information, the source should be named. If risk was assessed, the note should reflect the relevant findings and plan. If the diagnosis or code is uncertain, the clinician should review the full clinical picture, organizational policies, and payer requirements before finalizing the record.
For clinicians using AutoNotes, this review step is built into the documentation process. AI-assisted drafts can save time, but the final note should always reflect the clinician’s own assessment, judgment, and edits.
Build clearer conduct disorder notes with less after-hours writing
F91 documentation works best when it is specific, clinically grounded, and connected to the treatment plan. For conduct disorder confined to family context, that means documenting the family setting clearly. For other F91 codes, it means describing onset, settings affected, functional impact, interventions, response, and plan with enough detail to support ongoing care.
AutoNotes gives behavioral health professionals a faster starting point for structured, editable documentation while keeping the clinician in control of diagnosis selection and final note review.
