Your supplier should be able to tell you what your insurance limits are -- they're the ones with the vested interest in finding out your limit (they want to sell you exactly the maximum of what your insurance will cover so they can get paid). I had very good insurance when I had my ostomy and I could get up to 20 two-piece wafers and bags per month or 30 one-pieces.
