Selective Mutism
ICHI interventions for selective mutism in young children
ICHI has no single selective-mutism code; applicable interventions are assembled across its Target–Action–Means axes — graded exposure-based behavioural therapy for anxiety, communication support, caregiver and educator training, and education-setting accommodations. Coding combines relevant components, with anxiety reduction prioritised over eliciting speech.
Selective mutism rarely sits in one box — its intervention map spans communication, behaviour and family environment, and ICHI gives us a shared language for it.
In short
Selective Mutism (ICD-11 6B06) is an anxiety-based condition where a child consistently does not speak in specific social settings — typically school — despite speaking fluently at home. WHO's ICHI (International Classification of Health Interventions) does not list a single "selective mutism" code; instead, the applicable interventions are assembled across its Target–Action–Means axes — psychological and behavioural interventions on communication and anxiety functions, training and counselling delivered to the child and the family, and environmental adjustments in the educational setting. The practical map is graded exposure-based behavioural therapy, caregiver and school mediation, and communication support — never coercion to speak.The ICHI intervention map, briefly
Mapped against ICHI's structured axes, the interventions clinicians draw on for young children with selective mutism cluster as:- Psychological/behavioural interventions targeting anxiety and emotional functions — graded exposure (stimulus fading, shaping, the "sliding-in" technique), positive reinforcement of communicative attempts, and anxiety-management strategies appropriate to age.
- Interventions targeting voice and speech / communication functions — supporting nonverbal-to-verbal transition, augmentative bridges, and reducing performance pressure rather than drilling articulation (the child's speech mechanism is typically intact).
- Training and counselling provided to caregivers and educators — equipping parents and teachers to lower demand, avoid reinforcing avoidance, and create low-pressure opportunities to communicate across settings.
- Environmental and education-setting interventions — classroom accommodations, structured peer interaction, and transition planning so that gains generalise from home to school.
Because selective mutism is generalised across two or more axes, accurate coding requires combining the relevant ICHI components rather than seeking one label — and the clinical priority is anxiety reduction and graded exposure, not eliciting speech on demand.
When to refer
Refer when a child speaks competently in some settings but consistently fails to speak in others for more than one month (beyond the first month of school), where it is not explained by lack of language knowledge, hearing loss, or a communication disorder, and where it interferes with education or social participation. Early intervention markedly improves outcomes; co-occurring social anxiety and language difficulties should be screened.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form, a code list, or an app. Our clinicians translate the ICHI intervention map into a graded, family-and-school-mediated plan through speech therapy and behaviour therapy, benchmarked with the AbilityScore®.

What to watch
Consistent failure to speak in specific settings (e.g. school) for over a month, with fluent speech elsewhere; rising avoidance or distress; co-occurring social anxiety or language difficulty.
Try this at home
Never pressure or bribe a child to speak. Reduce the spotlight, allow nonverbal responses first, and reinforce any brave communicative attempt — a nod, a whisper, a gesture — so confidence builds before words follow.

Frequently asked
Is there a single ICHI code for selective mutism?
No. ICHI uses a Target–Action–Means structure rather than condition labels, so interventions for selective mutism are assembled by combining relevant components — psychological/behavioural interventions on anxiety and communication functions, caregiver and educator training, and education-setting environmental interventions.
What is the first-line intervention approach?
Graded exposure-based behavioural therapy (stimulus fading, shaping, the sliding-in technique) that reduces anxiety and rewards communicative attempts, combined with caregiver and school mediation. The goal is lowering performance pressure, not forcing speech.
When should a young child be referred?
When a child speaks fluently in some settings but consistently does not speak in others for more than a month (beyond the initial month of school), it is not explained by hearing loss or lack of language knowledge, and it interferes with education or social participation.
