About coding dysphasia
The ICD-10-CM code for dysphasia is R47.02 (Dysphasia). The official index lists 8 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R47.02.
Within R47.0 (dysphasia and aphasia), R47.02 is specifically for dysphasia. Related codes cover aphasia (R47.01).
Don't report R47.02 together with the conditions in its Excludes1 note: dysphasia following cerebrovascular disease (I69. with final characters -21).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
