Inclusion Terms

- Lalling

- Phonological developmental disorder
- Speech articulation developmental disorder
- Speech-sound disorder
Type 1 Excludes
- speech articulation impairment due to aphasia NOS R47.01

Type 2 Excludes

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical InformationClinical
Phonological Disorder
a disorder characterized by the failure to use developmentally expected speech sounds that are appropriate for the individual's age (i.e., the individual makes errors in sound production or use or omits sounds such as final consonants).
Patient EducationClinical
Speech and Communication Disorders
Many disorders can affect our ability to speak and communicate. They range from saying sounds incorrectly to being completely unable to speak or understand speech. Causes include:

Questions About F80.0Overview
Is F80.0 (Specific developmental disorders of speech and language) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report phonological disorder on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What is the ICD-9 equivalent of F80.0?
Under the General Equivalence Mappings, phonological disorder converts to ICD-9-CM 315.39 (speech/language dis NEC). The mapping is approximate, so confirm the match fits the documentation.
