Clinical notes
Excludes1 (not coded here)
An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).
Excludes2 (not included here)
An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.
- 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)
