Dementia ICD-10 Code (F03.90) Documentation Guide

F03.90 supports documentation for unspecified dementia without listed disturbances

F03.90 is an ICD-10-CM code used for unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety. In behavioral health documentation, this code may appear in intake notes, progress notes, treatment plans, care coordination records, and insurance-related clinical documentation.

For therapists, counselors, social workers, psychologists, psychiatrists, and other behavioral health professionals, the key task is not simply recording the code. The note should show the clinical picture that supports the documented diagnosis, the client’s current functioning, the services provided, and the clinician’s plan. Diagnosis selection remains the clinician’s responsibility. AutoNotes can help draft structured documentation from clinician-provided session details, but it does not assign diagnoses or replace clinical judgment.

F03.90 is most relevant when the record reflects dementia but does not specify a known etiology, severity level, or associated behavioral, psychotic, mood, or anxiety disturbance. Coding requirements can vary by payer, setting, and current ICD-10-CM updates, so clinicians should confirm diagnosis coding expectations through their billing process, EHR, supervising organization, or coding resource.

Clinical context that often appears with F03.90

Dementia documentation often includes more than memory concerns. A clinically useful note describes how cognitive changes affect daily life, relationships, decision-making, safety, emotional functioning, and treatment participation. For example, a client may miss appointments, repeat questions during session, struggle to manage medications, become disoriented in familiar settings, or rely heavily on a spouse or adult child for reminders.

Behavioral health clinicians may encounter F03.90 in several common scenarios:

• A client has an established dementia diagnosis from a medical provider, but the behavioral health record does not specify the dementia type.
• The client is receiving therapy for adjustment, grief, depression symptoms, caregiver conflict, or anxiety related to cognitive decline.
• A caregiver participates in sessions to support treatment follow-through, safety planning, or communication strategies.
• The clinical record does not document behavioral disturbance, psychotic disturbance, mood disturbance, or anxiety as part of the dementia diagnosis.

The note should avoid vague statements such as “client has dementia symptoms” without further detail. A stronger note describes observable concerns, client or collateral report, functional impact, and how the session addressed treatment goals.

What clinicians may need to document

Good dementia-related documentation helps another qualified professional understand the client’s presentation without guessing. It should connect the diagnosis, session focus, interventions, client response, and plan for continued care.

Presenting concerns and functional impact

Document the concerns that brought the client to treatment or shaped the current session. Include concrete examples when possible. “Client reports increased forgetfulness” is less useful than “Client reports forgetting to turn off the stove twice in the past month and now relies on daughter for meal preparation.”

Functional details may include:

• Memory, attention, language, orientation, or problem-solving concerns observed or reported
• Impact on activities of daily living, medication adherence, finances, transportation, or home safety
• Changes in social engagement, independence, family roles, or participation in treatment
• Collateral information from caregivers, medical providers, or case managers when clinically appropriate

Symptoms absent from the documented code

Because F03.90 indicates unspecified dementia without the listed disturbances, documentation should be clear when the session does or does not include behavioral, psychotic, mood, or anxiety symptoms. This does not mean every note needs a long checklist. It does mean the note should not contradict the code.

For example, if the note describes agitation, wandering, hallucinations, significant anxiety, or depressive symptoms connected to the dementia presentation, the clinician may need to review whether the current diagnosis code still matches the documented clinical picture. The clinician, not the documentation software, makes that determination.

Risk, safety, and level of support

Dementia documentation often benefits from a brief safety and support section. This is especially relevant when cognitive impairment affects driving, cooking, medication management, fall risk, financial vulnerability, or the ability to follow a crisis plan.

Depending on the session, the note may describe who is involved in care, what safeguards are in place, and what referrals or coordination steps were discussed. Keep the language factual. Avoid overstating risk if it was not assessed, and document any limitations in the available information.

Progress note elements for dementia-related sessions

A progress note for a client with F03.90 should still follow the same clinical logic as any other behavioral health note: what happened, why it mattered, how the client responded, and what happens next. SOAP, DAP, BIRP, GIRP, and narrative formats can all work if the note is specific and clinically coherent.

Useful elements include the session focus, interventions used, client response, progress toward treatment goals, caregiver participation when applicable, and the plan for follow-up. The note should also reflect any barriers caused by cognitive impairment, such as difficulty retaining coping strategies between sessions or needing written reminders.

Example SOAP note language

The following sample is for documentation style only. It is not a diagnosis recommendation, and clinicians should edit any note to match the actual session.

Diagnosis: F03.90 - Unspecified dementia, unspecified severity, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety

S: Client reported frustration with increased forgetfulness, including misplacing household items and missing two scheduled phone calls this week. Client’s spouse attended part of session and reported client benefits from written reminders.

O: Client was alert and cooperative. Client repeated one question multiple times during session and required redirection to return to topic. No behavioral disturbance, psychotic symptoms, mood disturbance, or anxiety symptoms were documented during this session.

A: Cognitive changes continue to affect daily routine and follow-through with coping strategies. Client engaged with session structure and was receptive to use of a written checklist. Spouse demonstrated understanding of reminder strategy.

P: Continue supportive therapy focused on adjustment to cognitive changes, caregiver communication, and use of external memory aids. Client and spouse will practice a daily written schedule before next session. Clinician will coordinate with medical provider as authorized by release of information.

This type of note gives a reviewer more than a code. It shows current symptoms, functional impact, intervention, response, and next steps.

Treatment planning considerations for clients with dementia

Treatment planning for dementia-related behavioral health services should be realistic, measurable, and tied to the client’s current cognitive capacity. The plan may focus on adjustment, emotional support, communication, caregiver involvement, safety, routine building, or coordination with medical and community supports.

Goals often need to be concrete. Instead of “improve coping,” a treatment plan might state, “Client will use a written daily schedule with caregiver support at least five days per week to reduce missed appointments and increase routine consistency.” This gives the clinician something observable to review in later sessions.

Common treatment plan areas include:

• Adjustment and emotional support: Processing grief, frustration, identity changes, or loss of independence related to cognitive decline.
• Memory support strategies: Practicing calendars, written reminders, labels, phone alerts, or caregiver-supported routines.
• Caregiver communication: Helping family members use clear prompts, reduce conflict, and support client autonomy where possible.
• Care coordination: Documenting releases, referrals, provider communication, and recommendations for additional medical or community support.

Progress should be measured against the client’s baseline and treatment goals. For some clients, maintaining routine participation, reducing distress during transitions, or improving caregiver follow-through may be clinically meaningful even if cognitive symptoms continue.

Common documentation problems to avoid

Dementia notes can become too brief, too general, or too focused on diagnosis labels. A note that says “worked on coping skills” does not explain what the clinician did or how the client responded. A note that lists severe symptoms without updating assessment, plan, or risk considerations may create confusion.

Watch for these documentation gaps:

• Code-note mismatch: The note describes agitation, hallucinations, major mood symptoms, or anxiety tied to dementia while the diagnosis code remains unchanged without explanation.
• No functional detail: The note mentions memory loss but does not describe how it affects daily living, relationships, safety, or treatment participation.
• Missing caregiver context: A caregiver participates in care, but the note does not identify their role, input, or interventions provided.
• Unclear medical coordination: The note references medical concerns but does not document releases, referrals, or coordination limits.

Another common issue is copying the same dementia-related language into every note. Repeated text can miss changes in presentation. Each session note should reflect what happened that day, even if the overall treatment focus remains stable.

How AutoNotes supports dementia documentation workflows

AutoNotes helps clinicians create structured, editable progress note drafts based on the information they provide. For dementia-related sessions, that can mean a clearer starting point for documenting cognitive concerns, caregiver input, interventions, client response, treatment goal progress, and follow-up plans.

The clinician remains in control. AutoNotes does not determine whether F03.90 is appropriate, assign a diagnosis, or finalize the clinical record. Instead, it supports the documentation process by organizing session details into formats clinicians already use, such as SOAP, DAP, intake, assessment, and treatment planning templates.

For a therapist who sees six clients in a day, this can reduce the friction of starting each note from a blank page. The clinician can enter session details, generate a draft, review the wording, correct anything that does not match the session, and finalize the note according to their professional standards and practice requirements.

A practical F03.90 documentation checklist

Before finalizing a dementia-related note, clinicians can use a short review process. The goal is not to make the note longer. The goal is to make it clearer.

1. Confirm that the documented diagnosis code matches the clinical record and current coding expectations.
2. Describe current cognitive or functional concerns with at least one concrete example when available.
3. Document interventions provided during the session and the client’s response.
4. Include caregiver participation, collateral input, or care coordination when relevant.

After that, check the plan. A strong plan should tell the next treating clinician what will happen next: continue weekly therapy, practice written reminders, obtain a release for provider coordination, monitor safety concerns, involve caregiver in next session, or review treatment goals at the next appointment.

Build clearer dementia notes with clinician-controlled AI drafts

F03.90 documentation should support the clinical story: the client’s cognitive and functional presentation, the services provided, the client’s response, and the plan for continued care. The code alone is not enough.

AutoNotes gives behavioral health clinicians a faster way to draft structured notes while preserving clinician review and decision-making.
