Medical Expense Deduction. You can deduct medical mileage as part of your overall medical expense deduction. The IRS limits the medical deduction to the amount of medical expenses in excess of 7.5 percent of your Adjusted Gross Income.
If you work multiple jobs, you can deduct the mileage you travel from one job to another, but not the miles you drive from your home to your workplace or vice versa. The mileage rate for business miles was 55.5 cents per mile in 2012 and 56.5 cents per mile in 2013.
