I am unclear on how to interpret this language from the 837I 5010 TR3, section 1.4.4.1: "Expressed as a calculation for given payer: {Loop ID-2320 AMT02 payer payment} = {sum of Loop ID-2430 SVD02 payment amounts} minus {sum of Loop ID-2320 CAS adjustment amounts}."
Suppose I have this data for loop 2320 & no 2430 loop:
SBR*S*01*GR1234567******BL~
CAS*CO*45*5000~
CAS*PR*1*4000~
AMT*D*1000~
Since there is no 2430 loop present, would the balancing be: 1000 = 0 - (5000 + 4000)? This would be false, which makes this 837I non-compliant, correct? The "0" above is since 2430/SVD02 is not present. Had AMT02 = -9000, it would be compliant. Is this correct?
Also, from HIR# 1115, is the balancing correct:
2300 clm_02 = 2320 AMT*D + sum of CAS adjustments in CAS_03,06,09,12,15,18?
The claim level COB calculation reflected in section 1.4.4.1 bullet 2 would only be performed when line level payment information exists. When line level payment information does not apply, there is no claim level COB balancing required for the claim.
There are two balancing calculations for the total claim charge amount (CLM02).
1) CLM02 = Sum of all service line charge amounts
2) CLM02 = the claim level prior payer paid amount + all claim adjustment amounts (CAS) at both the claim and service line (2320 and 2430)
