ICD-11 and Non-Verbal / Minimally Verbal Presentation

"Non-verbal" and "minimally verbal" describe how a child communicates today — they are functional descriptors, not diagnoses, and ICD-11 treats them accordingly.

In short

There is no single ICD-11 diagnostic code for "non-verbal" or "minimally verbal" presentation — these are functional descriptors of expressive communication, not standalone disorders. In ICD-11 they are captured in two complementary ways: the underlying condition is coded on the diagnostic axis (for example 6A02 Autism spectrum disorder, with the qualifier for accompanying language impairment; 6A00 Disorders of intellectual development; or 6A01.1 Developmental language disorder), while the degree of spoken-language limitation and its real-world impact is described using the WHO's ICF functioning framework. The phrase therefore signals where a child currently sits on the expressive-communication continuum, prompting a search for the mechanism rather than serving as the endpoint.

The science, briefly

Clinically, "minimally verbal" is conventionally applied to a child who uses few or no spoken words (often operationalised as fewer than around 20–30 functional words) beyond the age at which spoken language would be expected, while "non-verbal" denotes absent functional speech. ICD-11's structure deliberately separates the diagnosis from the functioning profile:

• Diagnostic axis — ICD-11 allows you to record the primary neurodevelopmental condition and, for autism, to specify with or without disorder of intellectual development and with or without impairment of functional language. This preserves clinical precision without forcing a child into a "verbal status" label.
• Functioning axis (ICF) — the WHO International Classification of Functioning, Disability and Health describes communication activity and participation, which is where the non-verbal/minimally verbal presentation is properly situated.

This matters because expressive output is not a fixed trait: a child described as non-verbal may have intact receptive language, may communicate richly through gesture, AAC or device, and frequently develops speech with the right support. Coding the mechanism — rather than the surface — keeps the door open to that trajectory.

When to refer

A child with limited or absent spoken language warrants prompt, structured developmental assessment to (a) exclude or quantify hearing loss, (b) differentiate developmental language disorder, autism spectrum disorder and disorders of intellectual development, and (c) establish a baseline communication profile. Early introduction of speech and communication therapy, including AAC where indicated, should not wait for diagnostic certainty.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a code, a checklist or an app. Our clinician-administered structured assessment profiles receptive and expressive communication together, so a child's presentation is understood as a starting point, not a ceiling. Across 70+ centres, our teams build a communication plan you can follow from day one.
