ICHI interventions for speech and language delay
ICHI does not give speech delay one code; it classifies the actions delivered — assessment of communication functions, speech-production training, language training, social-communication work, AAC provision and caregiver coaching. For ICD-11 6A01, pair an ICD-11 diagnosis with an ICF functioning profile and ICHI intervention language so the whole team reads one shared map.

A speech-and-language delay rarely needs a single intervention — it needs a coherent package, and ICHI gives us the shared vocabulary to name each component.
In short
ICHI (the WHO International Classification of Health Interventions) does not assign one code to "speech delay"; instead it describes the actions we deliver, classified along its Target–Action–Means axis. For a young child mapped to ICD-11 6A01 (developmental speech or language disorders), the relevant interventions cluster around assessment of communication functions, direct training of speech production and expressive/receptive language, training in social-communication and pragmatic skills, provision of augmentative and alternative communication (AAC), and parent/caregiver coaching. These map cleanly onto ICF activity-and-participation domains, which is exactly why we pair an ICD-11 diagnostic frame with an ICF functioning profile in practice.
The intervention set, by ICHI logic
Think in terms of what is being acted on (the Target), what is done (the Action), and how (the Means):
- Assessment & evaluation of communication functions — structured appraisal of expressive language, receptive language, speech-sound production, fluency and pragmatic use; establishes the baseline and rules out hearing loss or oromotor contributors.
- Training in speech production / articulation — therapist-delivered intervention targeting phonology, intelligibility and oromotor coordination.
- Training in language functions — building vocabulary, syntax, and receptive comprehension through play-based and elicited practice.
- Training in interpersonal & social-communication skills — joint attention, turn-taking, gesture and conversational pragmatics.
- Provision of AAC — picture-based or device-supported systems where verbal output is limited, supporting communication while speech develops.
- Caregiver/parent training & advisory interventions — coaching families to embed responsive language strategies into daily routines, which is the single highest-yield lever in this age band.
In day-to-day records, the practical discipline is: code the diagnosis in ICD-11, describe functioning in ICF, and select intervention language from ICHI so referrers, therapists and funders read the same map. Always confirm hearing status before attributing delay to a primary language disorder.
When to refer
Refer for formal speech-language assessment with no babble or gesture by 12 months, no single words by 16 months, no two-word phrases by 24 months, any loss of previously acquired words, or persistent parental concern at any age. Audiology review should run in parallel.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online form or this overview. Across 70+ centres with 700+ therapists, we translate this ICHI-aligned intervention set into an individualised plan.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
No babble or gesture by 12 months, no single words by 16 months, no two-word phrases by 24 months, or any loss of acquired words — refer for speech-language assessment with parallel audiology review.
In everyday life
Code diagnosis in ICD-11, describe functioning in ICF, and select intervention language from ICHI — one child, three complementary classifications, one shared plan.

Bring your questions to a first visitQuestions families ask
Is there a single ICHI code for speech delay?
No. ICHI classifies interventions, not conditions. A child with developmental speech or language disorder (ICD-11 6A01) will have several applicable intervention descriptors — assessment of communication functions, speech-production and language training, social-communication work, AAC provision and caregiver coaching — selected along the Target–Action–Means axis.
How do ICD-11, ICF and ICHI fit together here?
ICD-11 names the diagnosis (6A01), ICF describes functioning and participation, and ICHI describes the interventions delivered. Using all three keeps referrers, therapists and funders working from the same map.
Should hearing be checked before attributing delay to a language disorder?
Yes. Confirm hearing status through audiology before attributing delay to a primary speech or language disorder, as undetected hearing loss is a common and treatable contributor.
