About coding Dyslalia
The ICD-10-CM code for Dyslalia is F80.0 (Phonological disorder).
Within F80 (specific developmental disorders of speech and language), F80.0 is specifically for Phonological disorder. Related codes cover Expressive language disorder (F80.1), mixed receptive-expressive language disorder (F80.2), speech and language development delay due to hearing loss (F80.4), other developmental disorders of speech and language (F80.8) and developmental disorder of speech and language, unspecified (F80.9).
Don't report F80.0 together with the conditions in its Excludes1 note: speech articulation impairment due to aphasia NOS (R47.01) and speech articulation impairment due to apraxia (R48.2).
The conditions in its Excludes2 note aren't part of F80.0, but may be coded alongside it if the patient has both: 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) and speech articulation impairment with mixed receptive expressive language developmental disorder (F80.2).
Don't confuse with (Excludes1 for F80.0)
