In many cases, yes, though the specific interaction between VA pension income and Wisconsin Medicaid's income/asset eligibility rules requires individual review -- talk to your county ADRC's benefits specialist or a VA-accredited benefits counselor before assuming how the two programs interact for your specific situation.
More detail
Because Aid and Attendance is itself an income-based federal benefit and Wisconsin's Medicaid long-term-care eligibility also runs an income and asset test, the two programs can interact in ways that aren't always intuitive -- receiving one benefit can affect eligibility calculations for the other, depending on the specific numbers involved. This is exactly the kind of question where a general answer isn't reliable enough to act on; the ADRC of Milwaukee County (or your county's own ADRC) has benefits specialists specifically trained to help veterans and families work through Medicare, Medicaid, Social Security, and VA benefits together, rather than researching each program in isolation.
