About coding aphasia
The ICD-10-CM code for aphasia is R47.01 (Aphasia). The official index lists 17 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R47.01.
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.
