R47.8Other speech disturbances

R47.8 is the ICD-10-CM diagnosis code for other speech disturbances. It belongs to category R47 (speech disturbances, not elsewhere classified), 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 3 subcodes must be used instead.

Within R47, choose R47.8 (Other speech disturbances) only when documentation doesn't support a more specific option: dysphasia and aphasia (R47.0), dysarthria and anarthria (R47.1) and unspecified speech disturbances (R47.9).

To report this condition, pick the subcode that matches the documentation: R47.81 (speech), R47.82 (elsewhere) and R47.89 (disturbances).

Don't report R47.8 together with the conditions in its Excludes1 note: dysarthria following cerebrovascular disease (I69. with final characters -28).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
