ICD-10 Code F80.8 – Other developmental disorders of speech and language (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F80.8 – Other developmental disorders of speech and language
What it is
F80.8 identifies developmental speech or language disorders that do not fit a more specific ICD-10 category. Use it when the record supports a developmental communication problem, but the exact subtype is not documented.
Clinical signs
Clinical features vary; refer to documentation. You may see delayed speech or language development, difficulty expressing ideas, or problems understanding and using language compared with age expectations.
When to use this code
Use this code when the clinician documents a developmental speech or language disorder and no more specific code applies. It is appropriate for nonspecific language delay or mixed developmental communication findings when the chart does not support a narrower diagnosis.
Review the note for developmental history and the provider’s final assessment. If the documentation names a specific disorder, code that condition instead.
Do not use for
Do not use this code for acquired speech loss, hearing-related communication problems, or autism-related language issues unless the provider specifically diagnoses F80.8. Check documentation.
Coding tip
Code the most specific documented developmental communication disorder; use F80.8 only when the record remains nonspecific.
