I've read a lot about the allowables being different on here but typically the case is where both insurances are paying. I have where primary commercial insurance left everything towards deductible and secondary (Tricare) paid and left only a $31 copay but the allowable is over $40 lower. Can I only leave $31 to the patient when their primary left more being applied towards their deductible? I would think patient should be responsible for their deductible which would mean the difference in the allowable? Thanks!
