It reflects impaired planning and sequencing of articulatory movements, distinct from phonological disorder and dysarthria.","answer_md":"*A child who knows exactly what they want to say, yet cannot reliably make the mouth produce it — that is the clinical signature ICD-11 now codes precisely.*\n\n## In short\nIn **ICD-11-MMS**, Childhood Apraxia of Speech (CAS) is classified under **6A01.0 — Developmental speech sound disorder**, within the broader grouping of *Developmental speech or language disorders* (6A01) in the neurodevelopmental disorders block. CAS is the motor-planning subtype: speech production is impaired because of difficulty planning and sequencing the articulatory movements for speech, in the absence of neuromuscular deficit. The code captures a disorder of *praxis for speech*, distinct from phonological disorder or dysarthria.\n\n## The classification, in clinical terms\nICD-11 situates speech sound difficulties under **6A01.0 Developmental speech sound disorder**, the parent category that encompasses the apraxic presentation. The defining features that differentiate CAS from other 6A01.0 presentations are well established in consensus criteria: inconsistent errors on repeated productions of the same word, disrupted coarticulatory transitions between sounds and syllables, and inappropriate prosody — particularly lexical or phrasal stress. These reflect a deficit in the **planning and programming** of speech movements rather than in phonological representation alone.\n\nTwo distinctions matter at the point of coding:\n- **vs phonological/articulation disorder** — errors in CAS are markedly inconsistent and worsen with increasing length and complexity of utterance.\n- **vs dysarthria** — there is no consistent weakness, slowness or incoordination of the speech musculature; non-speech oromotor function is often preserved.\n\nICD-11 deliberately uses the ICF functioning frame, so the code describes impact on communicative participation, not a fixed prognosis.\n\n## When to refer\nRefer to a speech-language pathologist for differential assessment when a child shows groping articulatory behaviour, vowel distortions, inconsistent productions and limited consonant inventory disproportionate to receptive language. Early, intensive, motor-based therapy is the evidence-supported pathway.\n\n## The Pinnacle way\nA clinical **AbilityScore®** and any diagnosis are formed **only at a Pinnacle Blooms Network centre, under qualified clinician care** — never from a code lookup or an online form. Our clinician-administered structured assessment profiles speech-motor planning alongside language and oromotor function so that intervention targets the right level.
