It is a record-level terminology concept that maps to ICD-11 for morbidity classification, and clinically functions as a red flag warranting prompt evaluation.","answer_md":"*When a child loses skills they once had, the first clinical task is to name the phenomenon precisely — and SNOMED CT gives that language.*\n\n## In short\nIn **SNOMED CT**, *developmental regression* is represented by the concept **Developmental regression (finding)**, SCTID **62213004**, a clinical finding describing the loss of previously acquired developmental milestones (language, social, motor or adaptive). It sits within the body of clinical findings used to capture functional change over time, and is distinct from primary developmental delay (where skills were never attained). Note that SNOMED CT is a clinical terminology for the electronic record — for statistical and diagnostic classification you would map to the appropriate **ICD-11** category.\n\n## How the concept is used\nDevelopmental regression is a *finding*, not a diagnosis — it flags a pattern that warrants aetiological workup rather than naming a cause. Key points for coding and clinical reasoning:\n\n- **Specify domain and trajectory** — regression of expressive language differs clinically from global or motor regression; capture the affected domain and timeline in the record.\n- **Map deliberately across systems** — SNOMED CT supports the EHR; align with **ICD-11** for morbidity coding, recognising that one-to-one equivalence is not guaranteed and local terminology releases (including SNOMED CT India editions) may refine subtypes.\n- **Treat as a red flag** — any genuine loss of acquired skills, at any age, warrants prompt clinical evaluation to exclude treatable neurological, metabolic or seizure-related causes before a developmental formulation is finalised.\n\n## When to escalate\nDocumented regression — particularly rapid loss, motor regression, or regression with seizures or altered consciousness — is a medical-urgency presentation, not a therapy-first pathway. Route to paediatric neurology for investigation alongside developmental assessment.\n\n## The Pinnacle way\nA clinical AbilityScore® and any diagnosis are established **only at a Pinnacle Blooms Network centre, under qualified clinician care** — never from a code lookup or an online form. SNOMED CT gives the shared vocabulary; the [structured clinician-administered AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) gives the functional baseline. When regression is suspected, our teams coordinate developmental evaluation with [speech and language therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and onward medical referral as needed. Explore how we support families [here](/).\n\n## Trusted sources\nSNOMED International (SNOMED CT clinical terminology); WHO ICD-11 for Mortality and Morbidity Statistics; WHO ICF framework for functioning.\n\n**Next step —** Have a child presenting with skill loss?
