If you stay in a hotel while you are receiving treatment in an outpatient clinic, you can include up to $50 a day in your deductible medical expenses. The daily dollar limit is per person. If you travel with a sick child to get medical care, for example, you could deduct up to $100 a day for your lodging expenses.
