I echo Jan's astute opinion. I suspect some insurance company claims person made an error. Believe me, it happens. My wife used to be a claims supervisor for a major insurance company and 'mistakes were made' - often. Frankly, if your doctor has a letter from the insurance company approving the procedure it will very likely be paid by the insurance company. The only possible glitch would be if he or his office staff misunderstood something in the letter or, quite possibly, didn't submit the claim under the proper code (crucial - and a common error). Not to worry, if that is the case the doctors office can simply re-file his claim under the correct code. It's possible - but not probable - that the insurance company made an error in approving the BAHA. I'm not an attorney but I believe that even if they did make that error, as long as they sent the doctor a letter stating that the procedure was approved, they are legally liable to pay for it. So, no matter the cause of the 'glitch', I seriously doubt you'll be expected to pay for the procedure. However, 'worst case scenario': the doctor's office, would, as Jan stated, allow you both a discount and a 'time payment' plan. Rest assured, your daughter is very likely to get her BAHA. Now, please try to stop worrying. Because your doctor has an approval letter from the insurance company, I'm sure this is going to work out O.K. Really.
