Final answer:
The example "Dementia, with, Parkinson's disease /[F02.80]/ G20" is incorrect because it is not written in a standardized or recognized format. The correct format for representing the diagnosis of Parkinson's disease with dementia is "G20 with F02.80."
Step-by-step explanation:
The example "Dementia, with, Parkinson's disease /[F02.80]/ G20" is incorrect because it is not written in a standardized or recognized format. To correctly represent a medical diagnosis, the International Classification of Diseases (ICD) coding system is used. The correct format for representing the diagnosis of Parkinson's disease with dementia is "G20 with F02.80." The "G20" code represents Parkinson's disease, and the "F02.80" code represents dementia in other diseases classified elsewhere.
