About R47
R47 is the ICD-10-CM diagnosis code for speech disturbances, not elsewhere classified. It belongs to block R47-R49 (symptoms and signs involving speech and voice) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: R47.0 (aphasia), R47.1 (anarthria), R47.8 (disturbances) and R47.9 (disturbances).
Don't report R47 together with the conditions in its Excludes1 note: autism (F84.0), cluttering (F80.81), specific developmental disorders of speech and language (F80.-) and stuttering (F80.81).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
