Hearing Impairment
SNOMED CT concept for Hearing Impairment
In SNOMED CT, hearing impairment is the concept Hearing impairment (disorder), identifier 15188001 — a finding/disorder-axis term subsuming graded, sensorineural, conductive and mixed hearing loss. It maps to the WHO ICD-11 ear-disorder block for statistical reporting, preserving degree, type and laterality qualifiers for interoperable records.
Clean terminology mapping is the quiet backbone of every interoperable developmental record — and hearing impairment is one of the most clinically consequential codes to get right.
In short
In SNOMED CT, hearing impairment is represented by the concept Hearing impairment (disorder), SNOMED CT identifier 15188001 (a subtype of Disorder of hearing). It is a finding/disorder-axis concept describing reduced auditory function, and it subsumes a graded family of more specific concepts — for example Mild/Moderate/Severe/Profound hearing loss, Sensorineural hearing loss (disorder) and Conductive hearing loss (disorder). For statistical and epidemiological coding it maps to the WHO ICD-11 block for diseases of the ear (conductive, sensorineural and mixed hearing impairment), so a child's record can move cleanly between clinical and reporting systems.Why the distinction matters clinically
SNOMED CT is the reference clinical terminology for capturing what was found at the point of care, with rich hierarchical and relationship semantics; ICD-11 is the classification for counting and reporting. Using the disorder concept rather than free text preserves the laterality, degree and type qualifiers an audiologist or paediatrician documents — which is precisely what downstream speech-language and developmental teams need. In early childhood, a confirmed or suspected hearing impairment is also a critical differential: it must be actively excluded before attributing a language or social-communication delay to another cause, because untreated hearing loss masquerades as — and compounds — developmental delay.At the point of care
When coding, pair the disorder concept with its qualifiers (degree, type, laterality) rather than defaulting to the parent term alone, and ensure newborn hearing-screening outcomes are recorded discretely. Any infant who fails screening, any child with parental concern about hearing, or any unexplained speech-language delay warrants prompt audiological referral — diagnostic ABR/audiometry, not a watch-and-wait posture.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 lookup or an online form. For children where hearing impacts communication, our teams coordinate audiology findings with a structured developmental profile so the speech therapy plan reflects true auditory access.

What to watch
Failed newborn hearing screen, parental concern about hearing, inconsistent response to name or sound, or unexplained speech-language delay — each warrants prompt audiological referral rather than watch-and-wait.
Try this at home
When coding, attach degree, type and laterality qualifiers to the disorder concept rather than relying on the parent term alone, and record newborn screening outcomes as discrete data.

Frequently asked
What is the SNOMED CT concept and identifier for hearing impairment?
It is Hearing impairment (disorder), SNOMED CT identifier 15188001 — a disorder-axis concept under Disorder of hearing that subsumes graded and type-specific hearing-loss concepts.
How does it differ from ICD-11?
SNOMED CT captures the granular clinical finding at the point of care with degree, type and laterality semantics; ICD-11 classifies the condition within its ear-disorder block for statistical and epidemiological reporting. Both are used together for interoperable records.
Why exclude hearing impairment before attributing developmental delay?
Untreated hearing loss mimics and compounds speech-language and social-communication delay. Audiological status must be confirmed before a delay is attributed to another cause, which is why failed screening or parental concern warrants prompt referral.
