EDIT: With further research found this:

See page 5 "When you reach full retirement age"
How old is your wife? And if I understand correctly, she is currently receiving her SS retirement benefits.
My understanding is that Disability benefits are paid when someone is prevented from working and earning a living. There are a number of rules on this and it can be difficult to gain the "disabled" status.
I seriously doubt that the SS will give your wife both benefits, or even disability...even if such benefit was greater than her retirement benefit.
In part, see:

I have read in the past about disability benefits converting to retirement benefits at retirement age. Never the reverse.
You might want to do further research with "Google" and at the SSA website (https://www.ssa.gov). Or visit your local office or give them a phone call.

My wife has been diagnosed with CML (a type of Leukemia) which is listed as a condition of disability by SS. She has been receiving regular SS benefits for 5 years now. Question is, does she have the right to apply for disability benefits after receiving regular SS retirement benefits?
