Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code F80.0:

Inclusion Terms

Inclusion Terms
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.
  • Dyslalia
  • Functional speech articulation disorder
  • Lalling
  • Lisping
  • Phonological developmental disorder
  • Speech articulation developmental disorder
  • Speech-sound disorder

Type 1 Excludes

Type 1 Excludes
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.
  • speech articulation impairment due to aphasia NOS R47.01
  • speech articulation impairment due to apraxia R48.2

Type 2 Excludes

Type 2 Excludes
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.
  • speech articulation impairment due to hearing loss F80.4
  • speech articulation impairment due to intellectual disabilities F70 F79
  • speech articulation impairment with expressive language developmental disorder F80.1
  • speech articulation impairment with mixed receptive expressive language developmental disorder F80.2

Information for Patients

Speech and Communication Disorders

Also called: 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

  • Hearing disorders and deafness
  • Voice problems, such as dysphonia or those caused by cleft lip or palate
  • Speech problems like stuttering
  • Developmental disabilities
  • Learning disabilities
  • Autism spectrum disorder
  • Brain injury
  • Stroke

Some speech and communication problems may be genetic. Often, no one knows the causes. By first grade, about 5 percent of children have noticeable speech disorders. Speech and language therapy can help.
