I read through what you said. Again, my understanding is not 100% because I am not familiar, but I can see some issues.
My ostomy supplies are also through Coloplast. To the best of my knowledge, you are correct, when I inquired about a needs program from them (in case I lost my insurance), they said no. Hollister, on the other hand, does have one of these programs to the best of my knowledge (a discount type program). I'm not sure about ConvaTec, and those are the three ostomy supply manufacturers that are big and that I know (I assume they carry caths too).
There are several sites online that stock this when I ran it online. I did a Google (then click on Shopping) search for the name you gave. Found them down to $1.56 to my zip code, sometimes $1.77. That is a difference from what you were quoted, although I will tell you that internet prices vary depending on where you search from (so your quotes may be higher). Do be sure to sort the Google Shopping list Price: Low-High. I would also suggest running variations of the names to see if you get different results in case a different site lists it differently.
There are also lists of out-of-pocket suppliers (for ostomy supplies, but most sell caths too) - on the
UOAA Discussion Boards. There's several ads on the top of the page and then there have been many discussions on the cheapest / best place to get supplies.
In my (ostomy) experience, Edgepark is known as the most expensive, Byram is known as expensive (but I use it because they are the most accurate, and when I order I want what I ordered, not a substitution!! (I'm terribly allergic to most stuff...)), and then many people use Sterling for out of pocket. Byram does give a 10% discount if you pay out of pocket, but I find that to be too expensive.
Another place you might check is
IndeMedical. I stumbled onto this site one time while looking for wheelchair parts and they beat a price quote (without me even saying anything about a previous quote for the part) by about $100. For the caths, I get the price down to $1.44 for singles, and then a box of 100 should be $144 or less, but it's $154...so if I were you, I'd just order 100 singles and save myself the $10,

(away before someone

me, laugh).
There are probably many other sites out there, not sure what is the least price...but it can't really hurt to spend time looking for the best price, especially if you can get it down to $1.44 from $2.25. That's a huge price difference, about 64% if I did the math right?
If I were you, I'd also consider talking to an insurance advocate at your state level, and seeing if there is anything you can do. It may be unlikely, but I think it would be worth a call. The worst answer that you can get is "that's correct, we can't do anything" - but at least you would know.
Again, PM me or post back to let me know how it's going and if there's anything more someone can do to help.
Take care and good luck! I'm sorry the news wasn't better, but if you could get the same price quotes I got, and find the caths for $1.44 or even cheaper, that would at least be a start.
