ICD-10 Code F80.89 – Other developmental disorders of speech and language (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F80.89 – Other developmental disorders of speech and language
What it is
F80.89 identifies developmental speech or language disorders that do not fit a more specific ICD-10 category. Use it for persistent communication delays or abnormalities that are present in development and not better explained elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Common findings include delayed speech development, reduced expressive language, or difficulty using language appropriately for age.
When to use this code
Use this code when the record documents a developmental speech or language disorder and the provider does not name a more specific diagnosis such as expressive language disorder or mixed receptive-expressive language disorder. It is appropriate when the condition is developmental, ongoing, and clearly distinct from acquired speech loss. Check documentation if the type is not specified.
Do not use for
Do not use F80.89 for acquired aphasia, hearing-related speech problems, or normal age-related language variation. If the note supports a more specific developmental speech or language diagnosis, code that instead.
Coding tip
Code the most specific speech or language disorder documented, and use F80.89 only when the record supports a developmental disorder but gives no better subtype.
