Claim for Lancet Laboratories

I have reviewed the claim dated 14th October 2011.

According to the billing rules, the laboratory is allowed to bill for code 4076 up to a quantity of 6 times. According to our records, the practice had billed for the code 4076 for a total of 8 times therefore the 2 codes have been rejected. You are not liable for the amount.

Should the practice wish to confirm this, the practice can contact our Health Partners division on 0860 44 55 66 in order to confirm the billing rules.
This billing is from a laboratory, Lancet, who claim they own the machine and have the right to bill for its use. Now, Lancet is threatening me with ITC and Discovery refuse to pay, saying I do not have to either. It was in hospital and I agree with Lancet, but Discovery has said their final piece and now I am in the middle. The amount is trivial, under R400, but it is the principle of it. Discovery is getting away with murder and also refused to pay some medicine that were used on the grounds that it is not registered. I feel I can blow my top and reported the drugs that was not paid to the Medical Scheme authorities, but not this as yet. In any case, it does not help any to report them as an individual. I pay an arm and a leg for the best plan at Discovery, but must still pay for some services myself. I feel Discovery is taking small amounts from everyone, which ends up being a huge amount of money at the end of the day and they do it because they know they can get away with it.

Lancet on the other hand is ignoring what Discovery is saying in that I do not have to pay. They insist that I must pay and gave me a final warning. So they are also defenseless against Discovery and is not interested in taking on the big guy. Much easier to nail the small guy. Bloody sissies!

What would you do?
