Parse every PLB provider-level adjustment segment in an X12 835 remittance file and reconcile the adjustments against expected contract payments before posting to accounts receivable

Steps

1. After processing all CLP claim payment loops, locate PLB segments that appear before the SE segment at the provider level; each PLB carries the provider NPI in PLB01, the fiscal period date in PLB02, and up to three adjustment reason and amount pairs in PLB03 through PLB08
2. Map PLB03-01 and PLB05-01 adjustment reason codes to your internal adjustment categories: common codes include WO for withholding, CR for recoupment of a prior overpayment, and FB for forwarding balance from a prior period
3. Calculate the net PLB effect: positive amounts increase the payment and negative amounts reduce it; the total of the BPR payment amount minus all PLB negative adjustments plus all PLB positive adjustments must match the actual ACH deposit amount
4. For recoupment-related PLB adjustments identified by appropriate reason codes, retrieve the original claim associated with the recoupment using any REF reference numbers provided in adjacent segments and open a correspondence or dispute record
5. Post PLB adjustments to a dedicated provider-level adjustment GL account separate from claim-level CAS adjustments, because PLB adjustments are not associated with individual claim lines and cannot be attributed to a specific service
6. Reconcile the final 835 check amount against the BPR02 payment amount and confirm PLB net adjustments account for the difference before closing the remittance batch
