While this rejection message from the payer is quite long, there are few clues within it that indicate what they are referring to.
- They mention Service Line COB Information is invalid. This is an indication that this is a secondary claim that you submitted and that some of the payment/adjustments you entered from primary must not be valid.
- They mention Must not contain a negative amount. This is an indication that the you might have entered the total of the payments and adjustments you have entered is greater than the original charge amount for the session.
For each session on this claim, look at the payments and adjustments that you entered from primary. The sum of the payments, adjustments and patient responsibility must equal the charge amount. For example, if the charge amount was $150.00, then the sum of payments from primary, adjustments from primary and the patient responsibility that you entered from primary must equal $150.00.
