ICD-10 F94.1 / F94.2: Reactive Attachment and DSED Billing Guide

ICD-10 F94.1 and F94.2 cover Reactive Attachment Disorder (RAD) and Disinhibited Social Engagement Disorder (DSED) — two childhood-onset attachment diagnoses that typically arise in the context of neglect or early institutional care. These codes present specific billing considerations around child therapy CPT codes, family and caregiver session codes, and documentation of developmental history.

What Do F94.1 and F94.2 Mean?

F94.1 and F94.2 both map to DSM-5 diagnoses that result from insufficient caregiving (neglect, repeated changes of primary caregiver, or institutional rearing) in early childhood. They represent two distinct but related attachment-based disorders:

• F94.1 — Reactive Attachment Disorder (RAD): Inhibited pattern. Child rarely or minimally seeks or responds to comfort when distressed. Persistent social and emotional disturbance (minimal social and emotional responsiveness, limited positive affect, unexplained irritability/sadness/fearfulness). Must be present before age 5; child must have experienced extremes of insufficient care.
• F94.2 — Disinhibited Social Engagement Disorder (DSED): Uninhibited pattern. Child actively approaches and interacts with unfamiliar adults; reduced or absent reticence with strangers; willingness to go off with an unfamiliar adult. Also results from pathogenic care; can persist even after adequate caregiving is established.

Child Therapy Context: What These Diagnoses Look Like in Practice

RAD and DSED are exclusively childhood diagnoses — they cannot be first diagnosed in adulthood. In clinical practice, these clients are typically:

• Adopted children or children in foster care with early neglect histories
• Children who spent early years in institutional settings
• Children with a documented history of abuse or severe neglect prior to age 5

Treatment is typically caregiver-focused as much as child-focused. Dyadic therapy (therapist + child + caregiver together), parent-child interaction therapy (PCIT), and Attachment and Biobehavioral Catch-up (ABC) are evidence-based approaches. This treatment structure has direct implications for which CPT codes are billed.

How to Bill F94.1 / F94.2 on a Superbill

Unlike most adult diagnoses, attachment disorder treatment frequently involves multiple billing codes across sessions:

• Sessions with the child only → 90837 or 90834 (individual psychotherapy; the child is the identified patient)
• Sessions with child + caregiver together → 90847(family psychotherapy with client present). The child is still the identified patient; the caregiver's participation is part of the treatment for the child's condition.
• Sessions with caregiver only (parent coaching without the child) → 90846(family psychotherapy without the patient present). This is billable when the session is focused on the child's treatment goals, not the caregiver's own mental health.
• Initial assessment → 90791 (psychiatric diagnostic evaluation). The identified patient is the child; document the developmental history, attachment observations, and caregiver interaction patterns.

CPT Codes Commonly Paired With F94.1 / F94.2

• 90837 — 60-minute individual psychotherapy with child. Appropriate for play therapy, trauma-informed work, and child-directed attachment-building sessions.
• 90791 — Psychiatric diagnostic evaluation. Document full developmental history including early care environment, placement history, and attachment observations.
• 90847 — Family therapy with identified patient present. Dyadic therapy sessions (child + caregiver) — the workhorse code for attachment disorder treatment.
• 90846 — Family therapy without the patient present. Caregiver-only coaching sessions, parent psychoeducation about attachment, and caregiver skill-building without the child present.

Documentation Requirements

• Developmental history: early caregiving environment documented (neglect, abuse, institutional care, multiple placements, adoption history)
• Age of onset: symptoms present before age 5 required for both RAD and DSED
• Inhibited vs uninhibited pattern clearly documented to support F94.1 vs F94.2 code selection
• Observation of attachment behaviors: child's response to distress, response to unfamiliar adults, response to caregiver — documented from clinical observation or caregiver report
• Identified patient is the child — superbill should reflect the child's name, DOB, and diagnosis; caregiver is not a co-patient on the child's superbill
• Treatment modality and goals: dyadic therapy, PCIT, ABC, or other evidence-based approach named in the treatment plan
• For 90846 (parent-only sessions): note that session is in service of the child's treatment goals, not the parent's own therapy

Common Denial Reasons

• Identified patient confusion:Billing 90847 with the caregiver's name and insurance ID rather than the child's creates claim errors. The child is the patient; the superbill must use the child's information.
• 90846 without child treatment context:Parent-only sessions billed without documenting their connection to the child's treatment may be denied as individual adult therapy (which may not be covered under the child's policy).
• Lack of developmental history: RAD and DSED claims without documentation of the pathogenic care history may trigger medical necessity reviews, as the diagnosis requires this etiological context.
• Age criteria: These diagnoses require childhood onset. If a client is an adult, RAD/DSED cannot be newly diagnosed; document the childhood onset history explicitly.
