Some kind of general fitness testing?

You know, involving heart, lung capacity, performance?

I'd say colonoscopy, esp if you're over 45, but those are required by law to have no out-of-pocket costs, regardless.

Gender reassignment surgery?

My wife is there.

She's gotten two knee replacements this year and is scheduled for a hip replacement before the end of the year. And last night I reminded her she's been meaning to go to a dermatologist.

Go to all the specialists! And if therapy is covered, indulge in that, too.

Tape worm weight loss, or if you are already at a healthy weight start roids for a couple months

Physical therapy if you have any physical issues at all, massage therapy if you have any chronic pain, occupational therapy if you have specific life skills or mobility needs.

Any preventative screening or vaccines. There are various generic cancer screenings, etc. Get a referral to a dermatologist to do a once over your skin and document any spots of concern.

Get a Dietician and physical trainer. Use this opportunity to get yourself into healthy shape and never look back. I did something years ago and had no clue just how bad I was actually feeling before the improvement. Both physically and mentally. We are not designed to sit at desks all day.

Do your feet crack sometimes? Consider testing for athletes foot.

Blood, STD and Cancer screenings, as many as they’ll give you. Hell, depending how old you are, maybe a colonoscopy.

Sleep study. MRI, ECG, EKG. Allergy test. Dermatology/mole screening.

IQ test, find out your best skills and then learn how to use them to your advantage.

DNA testing, if you really want to know some things you may be perceptive to…though personally i don’t know if I would want to know if Huntingtons is in my future.

Talk to your primary doctor if they can get you a referral for an MRI. Insurance loves to try and deny MRIs, so I think a referral is probably required due to how expensive they are. IMO, they should be included in annual physicals since it's one of the only (if not the only) ways to detect brain tumors early, which is critical given how difficult it is to treat brain tumors and the earlier the better.

Vasectomy if you don't plan on having kids. Also consider mental healthcare. Everybody could use a little bit now and then.

Find a excuse to get physical therapy.

This is the perfect opportunity to recreationally infect yourself with rare short term diseases. Try breaking your arm or nose so you have a story. Self harm has never been so cheap.

Edit: See evasive_chimpanzee's comment here, as the following seems to be incorrect information

Seriously though get checked for prostate cancer. Especially if you're over 25 it's very possible and catching it early will be a massive difference.

Same for everyone reading this. I doubt it's that expensive so please look into it and get checked if affordable where you are.

Do you have any persistent pain or discomfort when doing things? Get that checked out.

Another +1 for colonoscopy.

Also if there's a family history of anything nasty, see if there's a test for it my maybe? (E.g. heart attacks, get blood work done for cholesterol).

Get a full physical including blood work.

I don't know what's covered under US "healthcare", and I think it also depends on your age. Probably should talk to your doctor and ask them. Maybe a bunch of blood tests, dental work, cancer screenings, prostate check, colonoscopy, and upper endoscopy.

Do you snore? Get a sleep study and a CPAP - thats pricy! Need a colonoscopy? Gel shots in your knees? Any family histories that would warrant testing for cancer markers?
