What Is X12 835 CLP03? Total Claim Charge Amount, Explained for Testers
CLP03 is the anchor number every other amount on the claim gets compared against. If it doesn't match what was actually billed on the corresponding 837, your reconciliation dashboards will show variances that have nothing to do with the payer's adjudication.
CLP03 reports the total amount originally billed for the claim, expressed as a decimal dollar figure with no currency symbol or thousands separator. It should mirror the total charge amount reported on the original 837 claim submission (CLM02), and it stays fixed regardless of how much the payer ultimately decides to pay.
What this element contains
Example
The claim was originally billed at $450.00, shown in CLP03 regardless of how it was later adjudicated.
Where this trips people up
When synthetic test files are generated independently for the 837 and the 835, it is easy for the charge amounts to drift apart because each generator invents its own number. Real payers echo the billed amount exactly, so a mismatch between CLM02 on your test 837 and CLP03 on the matching test 835 will make your reconciliation tests fail for a reason that would never occur in production.
