# What is the SNOMED CT concept for Dyslexia (Reading Impairment)?

Canonical: https://pinnacleblooms.org/ask/what-is-the-snomed-ct-concept-for-dyslexia-reading-impairment
Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

In SNOMED CT, dyslexia maps to concept 84229001 (Dyslexia, disorder), with developmental dyslexia under 192352006; this corresponds to ICD-11 6A03.0, Developmental learning disorder with impairment in reading. SNOMED CT supports granular clinical documentation and ICD-11 supports classification — the two are routinely cross-walked.

*Coding dyslexia correctly across SNOMED CT and ICD-11 is what keeps a child's reading-impairment record interoperable from referral to therapy plan.*

## In short
In **SNOMED CT**, Dyslexia (developmental reading impairment) maps to the clinical finding concept **84229001 — Dyslexia (disorder)**, with the closely related **developmental dyslexia** captured under concept **192352006**. This corresponds to **ICD-11 code 6A03.0 — Developmental learning disorder with impairment in reading**, the contemporary classification for a specific, persistent difficulty acquiring reading accuracy and fluency despite adequate instruction and intact sensory ability. The two systems serve different purposes — SNOMED CT for granular clinical documentation, ICD-11 for statistical and diagnostic classification — and are routinely cross-walked in interoperable records.

## The clinical concept, briefly
Developmental dyslexia is a neurodevelopmental disorder of reading, distinct from acquired (alexic) reading loss. The hallmark is a marked, unexpected shortfall in word reading, decoding and spelling relative to age, schooling and overall cognition. Under ICD-11, 6A03.0 sits within the **6A03 Developmental learning disorder** family; it presumes adequate educational opportunity and excludes impairment attributable to intellectual disability, uncorrected visual or hearing deficit, or another neurological condition. When documenting in SNOMED CT, prefer the specific developmental concept (192352006) over the broader finding (84229001) where the clinical picture is developmental rather than acquired, and pair it with the relevant ICD-11 code for classification and reporting.

## When to refer
Refer for structured assessment where reading and spelling difficulty persists beyond the expected window of early literacy acquisition (typically not reliably diagnosable before ~6–8 years), is disproportionate to cognitive ability, and is not explained by sensory or instructional factors. Co-occurring speech-language, attentional or motor-coordination concerns should prompt a broader developmental profile.
