@Ren I am not sure if you live in the U.S. (and have U.S. insurance coverage) but if you do, then the labs at OMI should be covered. It is true that the initial exam and follow-up visits are not covered but all of my lab work has been covered (and my insurance denies everything!) All I have had is a $20 co-pay for each time I do tests with Quest or Lab Corp. I have never done Rituxan so I have no idea what that would cost and assume deleder is correct. I would not be a candidate for that anyway. But I also think it depends what you are looking for and what your focus is (like what Melamine said.)
I just want to gently point out that whether the labs are "covered" - and at what rate - depends on the details of one's insurance. Some people have to meet a deductible (which can be thousands of dollars on plans bought through state exchanges/federal exchange) before labs are covered. I'm required to use certain labs. If I don't, my labs aren't "covered" at all (my coverage at "preferred labs" is 80% of the allowable rate). Insurance companies can also decide that a certain lab is "investigational" and thus, will not be covered at all (and therefore, you pay the much higher rate the lab charges uninsured people rather than the contracted rate - which in my case, averaged about 1/10 of the amount Quest initially billed (I paid 20% of the 1/10!) In other words, Quest would bill $100; my insurance had a contract with Quest that allowed $10; insurance paid $8; I paid $2.
If money is a serious issue for a person, and if insurance doesn't cover a lot of the lab tests, they can add up, so without knowing the specifics of someone's insurance, you cannot even begin to determine what their coverage for labs will be. Although I realize being seriously ill is expensive (if you can't work, that's expensive!), some people just can't afford a hit of $1000 or $2000 or more financially.
The initial prices Quest billed for my labs at OMI added up to $7500 or so. My insurance decided the one test was "investigational" (I'm in the process of appealing this; billed amount was about $400 which I'd have to pay in full if coverage is denied after appeals are exhausted; since this test was deemed "investigational", the $400 will not count toward either my deductible or "total out-of-pocket" annual limit). Eventually I'm going to post some of the details of the tests, such as test name, price Quest initially billed, and the contracted price my insurance allowed.
It's horrendous how Quest bills at a rate 8-12 times what the insurance company contracts for. Obviously, Quest is making money off the contracted prices, so they're making a fortune off of individuals who end up paying the "billed" price. If anyone wants some of these details, PM me - I'll share them. I'll probably round the dollar amounts just to preserve a bit of privacy (if insurance companies try to track where the data came from). To a degree, everyone is going to have somewhat different tests performed, but there probably are quite a few that most people have (unless they have lab results from prior testing). You can try to ask your insurance company if certain labs will be covered, but they very well may tell you "it depends on your diagnosis" which you won't get until you see the physician.
Although I can include the contracted price, there's no guarantee that's the contracted price for YOUR plan, even if you got your insurance through the same company from me. I changed plans from Jan to Feb of this year, and the contracted rate for a prescription at the same pharmacy was 50% higher in one month than the other. (Study your explanations of benefits - you will likely be very surprised at the "billed" amounts vs. contracted/allowed amounts.) Luckily, I only had to pay the co-pay. One plan was purchased directly from the insurance company (Jan) while the other (Feb) was purchased from the health exchange in my state. Other than that, the plans were essentially the same. Insurance is truly a mystery. Keep in mind that insurance laws vary from state to state - the ACA made it somewhat more uniform, but far from identical.
