How will Medicaid effect the annuity my sick dying grandmother made me beneficiary of?

What kind of annuity?
Is it in payout mode?
Is it Medicaid compliant (actuarial sound) for how funded?
Has gran applied for Medicaid? or is this more that it’s looking like she’s going to need to apply for Medicaid as she’s needing care in a facility?

Do you at all know how she got the annuity? Like was it sold to her at/from one of those free dinner “investment”seminars?
