SNOMED CT concept for Developmental Language Disorder

A precise code keeps a child's record interoperable — DLD must map cleanly from ICD-11 to SNOMED CT for clinical exchange.

In short

Developmental Language Disorder (DLD) is represented in SNOMED CT by the concept Developmental language disorder (disorder), SCTID 702988008. In the WHO classification it sits at ICD-11 6A01.2 — Developmental language disorder, within developmental speech or language disorders. SNOMED CT is the structured clinical terminology used for EHR documentation and interoperability, while ICD-11 serves statistical and morbidity classification; the two are complementary, not interchangeable. Always confirm the SCTID against your current SNOMED CT International or India edition release, as concepts are versioned and may be refined.

The terminology, briefly

DLD denotes a persistent difficulty acquiring and using language — expressive, receptive, or both — that is not attributable to hearing loss, intellectual disability, neurological injury or an associated biomedical condition. When DLD co-occurs with a known differentiating condition (e.g. autism, sensorineural hearing loss), the construct is more precisely termed Language Disorder associated with that condition, per the CATALISE consensus. In SNOMED CT this maps to descendants under developmental language disorder; in ICD-11, qualifiers within the 6A01 block capture associated features. For coding workflows: use SNOMED CT at the point of care for granularity and post-coordination, and the ICD-11 6A01.2 stem for reporting. Verify mappings via the official SNOMED-ICD map files rather than assuming a one-to-one correspondence.

When this matters clinically

• Documentation — record the SNOMED concept alongside the functional profile, not in place of it.
• Referral & data exchange — consistent coding enables longitudinal tracking across speech-language pathology, audiology and paediatric services.
• Differential — exclude hearing impairment and global developmental delay before applying the DLD construct.

The Pinnacle way

Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — coding follows clinical formulation, never the reverse. Our speech therapy teams document against recognised terminologies so that a child's record travels cleanly between services. Learn how we establish a baseline via the clinician-administered AbilityScore®, part of how Pinnacle supports every family's journey.
