Deducting medical expenses paid over time

[user17759694586]

If I "pay" for a medical procedure using credit, and the actual installments occur in the following year, in what year are they deductible on my tax return? The year the full cost was incurred, or the year in which I make the installments?

if you pay by credit card, the charges are 100% deductible in the year they're charged to the card. if it is the medical facility or provider that is supplying the credit, only the principal payments made in the year are deductible
