What Is Payment Posting, and Why Does It Decide Your A/R?
Payment posting is the step in medical billing where every insurance and patient payment, contractual adjustment, denial and patient-responsibility amount is recorded against the exact claim line it belongs to. It turns a payer's remittance into an accurate ledger.
Everything after posting depends on it. A/R follow-up works from the open balances posting leaves behind. Patient statements bill the patient responsibility posting records, and secondary claims go out only after the primary payment is posted. When posting is late or wrong, every downstream step works from bad numbers.
What Your Remittances Reveal When They're Posted Right
A remittance looks routine until someone reads every line. Careful posting surfaces:
Underpayments
An allowed amount below your contracted rate, hidden inside a ‘paid’ claim.
Silent denials
A single service line denied while the rest of the claim pays.
Recoupments and offsets
Money a payer takes back from today's payment for an old claim.
Misapplied patient responsibility
A deductible or coinsurance recorded wrong, leading to an incorrect patient bill.
Missing payments
Claims marked ‘paid’ in the remittance but never matched to a deposit.
Complete Payment Posting Services, From Remittance to Reconciliation
Insurance Payment Posting (ERA Auto-Posting)
We load 835 ERA files into your PM system, then work every exception the auto-poster cannot handle: unmatched claims, split payments, bundled lines and reversals. Auto-posting does the volume; our specialists handle the judgment.
Manual EOB Posting
Paper and PDF EOBs from payers that don't send ERAs, including some workers' compensation and smaller plans, are keyed line by line within 48 hours.
Patient Payment Posting
Copays, card, check, portal, text-to-pay and lockbox payments are applied to the exact charge they cover, not dropped into unapplied cash. Patient balances stay accurate, and our patient billing team bills the right amount.
Denial and Zero-Pay Posting
Denied lines are posted at $0 with their CARC and RARC codes, then routed to denial management the same day while appeal windows are still open.
Underpayment Detection
Every allowed amount is compared to your contracted fee schedule at posting. Variances go to A/R follow-up for recovery.
Secondary and Crossover Claim Release
Once the primary payment posts, secondary and crossover claims, including Medicare-to-AHCCCS crossovers for dual-eligible patients, are released within 24 to 48 hours.
Credit Balance and Refund Management
Overpayments are identified at posting and refunded or offset correctly. Medicare overpayments are tracked against the 60-day return requirement.
Every Remittance Read Line by Line: The Codes We Work Daily
An ERA is a coded 835 file. Posting it correctly means reading every code and acting on it.
| Code or segment | What it tells us | What we do |
|---|---|---|
| CLP | The claim-level payment and status | Match to the claim; flag reversals and ‘processed as secondary’ |
| SVC | The payment for each service line | Post line by line, never as a lump sum |
| CO-45 | Charge exceeds fee schedule (contractual adjustment) | Post the write-off; compare the allowed amount to the contract |
| PR-1 / PR-2 / PR-3 | Deductible / coinsurance / copay | Move to patient responsibility for billing |
| CO-97, CO-16, CO-50 and others | Bundled, missing information, medical necessity | Post at $0; route to denial management the same day |
| PLB WO | Overpayment recovery (recoupment) | Apply the offset to the original claim, not today's payment |
| PLB L6 | Interest paid by the payer | Post as interest income, separate from the claim |
| TRN | Trace number linking the ERA to its EFT deposit | Reassociate payment to deposit for reconciliation |
Every Dollar Balanced to the Bank, Every Day
Posting a payment and proving it arrived are two different jobs. Every business day we match posted totals to the EFT deposits and lockbox batches in your bank account, using the ERA trace number.
Unmatched deposits and ‘paid’ ERAs with no deposit are investigated within 2 business days, so month-end close takes hours, not weeks. Your unapplied cash stays near zero.
Fluent in Arizona Payer Remittances
Arizona remittances have their own quirks. AHCCCS and its health plans, such as Mercy Care, Banner-University Family Care and Arizona Complete Health, each format remittances and recoupments their own way. Noridian handles Medicare Part B in Arizona, and BCBS of Arizona, UnitedHealthcare, Aetna and Cigna round out most local payer mixes. After 8+ years posting for Arizona practices, our team knows how each one reports adjustments, offsets and interest, and posts them correctly the first time.
