Hearing Impairment and its ICD-11 features in early childhood
Hearing impairment is reduced hearing sensitivity (conductive, sensorineural or mixed) classified in ICD-11 under ear diseases (AB50–AB5Z) by type, severity and laterality. In early childhood it threatens spoken-language acquisition, so failed newborn screens, absent orienting to sound, babble plateau and absent words by 16 months warrant prompt diagnostic audiology and early intervention.

A baby who does not turn to your voice is not ignoring you — they may simply not be hearing it, and the earliest months matter most.
In short
Hearing impairment is any reduction in hearing sensitivity — conductive, sensorineural or mixed — that limits a child's access to sound and, critically in early childhood, to spoken language. In ICD-11 it is classified under diseases of the ear (block AB50–AB5Z, Hearing impairment), graded by degree (mild to profound) and laterality. Because the first three years are the window for auditory-driven language acquisition, undetected loss carries disproportionate developmental cost — making newborn screening and prompt confirmation non-negotiable.
ICD-11 features in early childhood
ICD-11 frames hearing impairment by type, severity and configuration, mapped functionally to the ICF. In infancy the clinically meaningful features are:
- Failed or referred newborn screen (OAE/AABR) requiring diagnostic ABR confirmation
- Absent or reduced startle/orienting to sound; no turn to voice by ~6 months
- Babble that plateaus or regresses and limited consonant variety after 6–9 months
- No single words by 16 months, or vocabulary not building — a language delay that may be the first audible sign
- Risk markers: NICU stay, hyperbilirubinaemia, ototoxic exposure, congenital CMV, family history
Distinguish from global delay and ASD — though these co-occur and audiology must precede behavioural attribution.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an app or checklist. For confirmed loss, structured audiology-informed listening and spoken-language therapy is most effective when begun early; learn more on Hearing Impairment and how baseline functioning is measured via the AbilityScore®.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Failed or referred newborn hearing screen, no turn to voice by ~6 months, babble that plateaus or regresses, and no single words by 16 months — always order diagnostic audiology before attributing language delay to behaviour.
In everyday life
Advise parents that any persistent worry about a baby not responding to sound deserves a hearing check — a normal newborn screen does not rule out later or progressive loss.

How does ICD-11 classify hearing impairment?
ICD-11 places hearing impairment within diseases of the ear (block AB50–AB5Z), graded by type (conductive, sensorineural, mixed), degree (mild to profound) and laterality, with functioning mapped to the WHO ICF framework.
Why is early childhood the critical window?
The first three years are when auditory input drives spoken-language development. Undetected loss in this period disproportionately delays speech, language and learning, which is why newborn screening and rapid confirmation are essential.
Does a normal newborn screen rule out hearing loss?
No. Some losses are progressive, late-onset or acquired after the neonatal period. Persistent parental concern or delayed babble and words warrants diagnostic audiology regardless of an earlier passed screen.
