Speech Sound Disorder ICD-10 Code: F80.0 and Related Codes
The ICD-10-CM code for a speech sound disorder is F80.0, Phonological disorder, which also covers articulation disorder and lisping. Related codes include F80.81 for childhood-onset stuttering, F80.4 for speech delay due to hearing loss, R48.2 for apraxia, and R49.21 for hypernasality — from ASHA’s 2027 list.
F80.0: the speech sound disorder code
ICD-10-CM is the International Classification of Diseases, 10th Revision, Clinical Modification. ASHA culls the codes relevant to speech-language pathology into an annual list; the 2027 list took effect on October 1, 2026.2,1
| Part of the entry | What it lists |
|---|---|
| Inclusion terms | Dyslalia; functional speech articulation disorder; lalling; lisping; phonological developmental disorder; speech articulation developmental disorder; speech-sound disorder |
| Excludes1 (code elsewhere instead) | Speech articulation impairment due to aphasia NOS (R47.01) or due to apraxia (R48.2) |
| Excludes2 (separate condition, may also apply) | Due to hearing loss (F80.4); due to intellectual disabilities (F70–F79); with expressive language disorder (F80.1); with mixed receptive-expressive language disorder (F80.2) |
F80.0 Phonological disorder — inclusion terms and exclusions (ICD-10-CM FY2027, via ASHA).1
ASHA’s note on the F80 series: use it when there is no evidence or confirmation of an underlying medical condition contributing to the speech or language deficit; disorders due to a documented medical condition are generally found in the I69 and R00–R99 series. That mirrors the clinical split between idiopathic speech sound disorders, which have no known cause, and organic ones.1,3
What the code means for parents
A diagnosis code on a report or claim names the category, not the severity or the plan. ASHA describes a full assessment producing a diagnosis plus a description of the disorder’s characteristics, subtype, and severity, recommended treatment targets, and any referrals — that description tells you far more than the code.3
Coding decisions
This page summarizes ASHA’s published list for information. The treating clinician chooses the code, and payer rules vary. Codes are updated every October 1.
