Wiki alzheimers dementia

the icd-9 code 331.0- Alzheimer's disease states:

use additional code, where applicable to identify dementia:
with behavioral disturbance (294.11)
without behavioral disturbance (294.10)

so, I'd say both should be coded.

What if the word dementia is not used

How would you code Alzheimers in the instance that is the only word used and the word dementia doesn't appear in the assessment? In that case, would you code Alzheimers disease alone? (Let's just say the claim has to be in today and the provider is unreachable so you are coding "AS IS")
