Medical Expenses for Cancer Treatment in another State

[superdav]

I was diagnosed with Prostate Cancer.   In October I flew to Arizona from Idaho to meet with the Mayo Clinic regarding Treatment Options.  I spent 2 nights there in a hotel and used Uber as Transportation once there.  It was decided to head down there in November to begin treatment.  I had several preliminary appointments and tests from November through December 2025.  My actual Radiation Treatment began in January and  February of 2026.  We drove down in an RV and have stayed at a RV Park.  In the past we have come down as a Snow Bird usually in late January.  Treatment has finished but we will be staying through March.  That's the Background....

Question is What can I deduct as Medical Expense if I itemize expenses over the 7.5%?

And.....

What does significant mean below?, obviously we did some pleasure and recreational activities in between treatments

1. There is no significant element of personal pleasure, recreation, or vacation in the travel away from home.

Thanks in advance

Oops....looks like I'm in the wrong category....I re-posted it in Deductions and Credits

Review IRS PUB 502. There are sections on deductible travel and lodging.

Thanks....I've read that but I'm not sure I understand the Transportation and Lodging.  I'm guessing I can claim my Airfare and Lodging from my October Visit.  But I'm not clear of my RV traveling for my appointments in November and December.  Since I'm at a RV Park for longer than my treatment, can I claim $50 per day for me and my wife ($100 per day) for the days  I headed down through my treatment....but not afterward?

Thanks

Yes, deductible medical expenses for RV travel include transportation costs (mileage at 21 cents/mile in 2025 or actual gas/oil), tolls, parking, and up to $50/per night/person for lodging if the travel is primarily for and essential to receiving medical care. Expenses must exceed 7.5% of AGI to be deducted.

Details in IRS Pub. 502.
