What Is Payment Posting?
Payment posting is the revenue cycle step where insurance payments (from 835 ERA or paper EOBs) and patient payments are applied to specific claim lines and patient accounts in the practice management system, including contractual adjustments and denial transfers.
- Reconcile every 835's BPR total to the matching EFT deposit before the batch is closed.
- Track exception items — unmatched 835s, virtual credit card payments and their surcharges, takebacks — in a separate queue rather than inside normal posting, because each one needs a decision rather than a keystroke.
- Which payers still send you paper is worth auditing: EFT vs paper check on the posting side covers the enrollment process, the CAQH CORE operating rules, and the BPR-to-deposit reconciliation this control depends on.
Payment Posting
Also known as: Cash Posting; Remit Posting
Payment posting is the revenue cycle step where insurance payments (from 835 ERA or paper EOBs) and patient payments are applied to specific claim lines and patient accounts in the practice management system, including contractual adjustments and denial transfers.
Definition
Posting reconciles received payments against billed charges, applying CARC contractual adjustments, transferring patient responsibility (deductible, coinsurance, copay) to patient accounts, and routing denials and partial payments into denial work queues. Auto-posting applies the 835 files a payer sends electronically; what share of your insurance payments that covers is a number you measure from your own remits rather than an industry constant — no free primary source publishes an auto-posting rate, and the figure moves with payer mix and with how many of your payers still pay on paper. The remainder needs manual handling: paper EOBs, virtual credit card payments, and takebacks or recoupments carried in the 835's provider-level adjustment (PLB) segments. Patient payments arrive via card terminals, online portals, mailed checks, or lockbox services and require matching to the correct account and date of service.
Example
An illustrative posting, with the arithmetic shown so it reproduces. A claim line is billed at $163 for CPT 99213 and the plan's contracted allowed amount is $128. The 835 posts a $35 contractual adjustment under CARC 45 — the write-off of the charge above the contracted amount, not a denial — transfers $30 to the patient as deductible under CARC 1, and shows $98 paid by the plan, which is the $128 allowed less the $30 deductible. The line closes with a $30 patient balance, and a later $30 payment through the patient portal zeroes it. The dollar amounts are invented for the example; the relationships between them are what a correct posting has to satisfy.
Common Misconceptions
Posting is not just data entry — incorrect posting (wrong adjustment codes, missed PLB recoupments, misapplied patient payments) creates phantom A/R, secondary-billing failures, and refund liabilities. Posting must reconcile to the bank deposit at the file/batch level.
Practical Application
Posting turnaround is a target you set and hold yourself to, not a rule handed down by anyone: A/R aging and secondary billing are both wrong until the primary payment is posted, so whatever window you pick, measure against it. Reconcile every 835's BPR total to the matching EFT deposit before the batch is closed. Track exception items — unmatched 835s, virtual credit card payments and their surcharges, takebacks — in a separate queue rather than inside normal posting, because each one needs a decision rather than a keystroke. Which payers still send you paper is worth auditing: EFT vs paper check on the posting side covers the enrollment process, the CAQH CORE operating rules, and the BPR-to-deposit reconciliation this control depends on.
