Why Should I Have to Pay a Deductible Twice?

If a patient had surgery in 2014 and then complications from that surgery arise in 2015 should the new surgeries or procedures in 2015 be applied to the deductible? Since the preauth was for 2014 and i already hit my deductible and the surgery in 2015 was due to a complication from the 2014 surgery. This is a pre -existing condition from the same problem why should i have to pay a deductible twice? Is there any rules that could help me avoid a double deductible?
