For what it's worth, I talked to a representative on the Cover VA (Virginia) help line concerning Medicaid coverage for adult dependents. Her understanding was that when someone is claimed as a tax dependent, the income of the tax filer is used to determine eligibility for Medicaid. She also said that the Medicaid case worker had the final say. I previously talked to the case worker who told me she didn't know whether or not the filer's income was to be used to determine eligibility.
