Since the medical insurance was not established under your spouse's business it cannot be deducted as a Self-Employed Health Insurance Deduction.
The insurance premiums paid can be deducted on Schedule A as an itemized deduction. However, only your total medical expenses that are greater than 7.5% of your Adjusted Gross Income (AGI) can be deducted. Your total itemized deductions reported on Form 1040 Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.
