I'm preparing our tax documents to ship off to our accountant in California. I found this link that may provide you with some helpful information. Try to scroll through the whole thing because there may be a few hidden deductions you didn't know about.
2009 Medical and Dental Expenses
Did you know you can deduct transportation costs traveling to and from medical appointments?
You can include in medical expenses amounts paid for transportation primarily for, and essential to, medical care.
You can include:
Bus, taxi, train, or plane fares or ambulance service,
Transportation expenses of a parent who must go with a child who needs medical care,
Transportation expenses of a nurse or other person who can give injections, medications, or other treatment required by a patient who is traveling to get medical care and is unable to travel alone, and
Transportation expenses for regular visits to see a mentally ill dependent, if these visits are recommended as a part of treatment.
Car expenses. You can include out-of-pocket expenses, such as the cost of gas and oil, when you use a car for medical reasons. You cannot include depreciation, insurance, general repair, or maintenance expenses.
If you do not want to use your actual expenses, for 2009 you can use the standard medical mileage rate of 24 cents a mile.
You can also include parking fees and tolls. You can add these fees and tolls to your medical expenses whether you use actual expenses or use the standard mileage rate.
Tax time is stressful and every little bit helps.
