Does medical expense deduction need to be reduced for money raised via Gofundme?

This is a copy/paste from a google search:

In general, you can deduct qualified, unreimbursed medical expenses that are more than 7.5% of your adjusted gross income in 2019. So, for example, if your adjusted gross income is $40,000, anything beyond the first $3,000 of your medical bills — or 7.5% of your AGI — could be deductible.

Money given to you as a gift is still your money and not "reimbursed" by any kind of medical insurance.

Remember that when you itemize deductions like medical expenses, you can't take the standard deduction.  If your itemized list is not higher than your standard deduction, then it is always better to skip itemizing and just use the standard deduction.

If you SPENT $15,000 and raised $10,500 on gofundme, you had an out of pocket expense of $4,500.

Money is considered fungible.  After you received the gift, the money was to use as you please.  All $15,000 is deductible.

$4500, but your medical deduction has to exceed a certain percentage of your income.

Doesn't insurance or Medicare pay for that?

All of the money you received is personal gift with no tax issues for you at all. 

You bought the wheelchair with your own money.   If it's a deductible expense, deduct it.   You have the invoice and proof of payment, right?

Do you have enough deductions to make itemizing worthwhile?   You can only deduct medical expenses that are more than something like 7.5% of your AGI.   I'm sure someone will be along to correct my numbers if I'm off...

Deduct the entire amount.

The $10.5k were "gifts" and deductible expenses paid with gifted money is still deductible.
