About coding dysarthria
The ICD-10-CM code for dysarthria is R47.1 (Dysarthria and anarthria). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R47.1.
Within R47 (speech disturbances, not elsewhere classified), R47.1 is specifically for dysarthria and anarthria. Related codes cover dysphasia and aphasia (R47.0), other speech disturbances (R47.8) and unspecified speech disturbances (R47.9).
Don't report R47.1 together with the conditions in its Excludes1 note: dysarthria following cerebrovascular disease (I69. with final characters -22).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
