Qualified medical expenses are those incurred by the following persons:
A child of parents who are divorced, separated, or living apart for the last six months of the calendar year is treated as the dependent of both parents whether or not the custodial parent releases the claim to the child's exemption.
Even taxpayers who have a self-only HDHP may use the money in their HSA to pay the unreimbursed medical expenses for their spouse or other family members (as described above).
Taxpayers cannot deduct qualified medical expenses as an itemized deduction on Form 1040, Schedule A, that are equal to the tax-free distribution from their HSAs. Since the medical expenses have been paid from HSA funds, the taxpayers cannot include the same expenses on Schedule A.
