Within R47.0 (dysphasia and aphasia), R47.01 is specifically for aphasia. Related codes cover dysphasia (R47.02).
Don't report R47.01 together with the conditions in its Excludes1 note: aphasia following cerebrovascular disease (I69. with final characters -20) and progressive isolated aphasia (G31.01).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
