About coding Stuttering
The ICD-10-CM code for Stuttering is F80.81 (Childhood onset fluency disorder). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F80.81.
Within F80.8 (other developmental disorders of speech and language), F80.81 is specifically for childhood onset fluency disorder. Related codes cover social pragmatic communication disorder (F80.82) and other developmental disorders of speech and language (F80.89).
Don't report F80.81 together with the conditions in its Excludes1 note: adult onset fluency disorder (F98.5), fluency disorder in conditions classified elsewhere (R47.82) and fluency disorder (stuttering) following cerebrovascular disease (I69. with final characters -23).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
