What Is Payment Posting and Why Does Accuracy Matter?
The balance disappears from your A/R aging report, so no one follows up and the revenue is lost without anyone noticing.
Payment posting is the process of recording payer and patient payments, plus contractual adjustments and denials, against each claim in your billing system. Accuracy matters because clean posting reveals underpayments and denials that would otherwise go unworked. MB Claims treats posting as a revenue control, not just data entry.
What is the difference between ERA and manual posting?
ERA posting loads an electronic remittance advice (835 file) from the payer directly into your billing system, while manual posting means a person keys in payment details from a paper EOB or portal screen. ERA posting is faster and less error-prone, but it still needs human review of exceptions.
Neither method is automatically "right." Most practices use both, because some payers, workers' compensation carriers, and patient payments still arrive on paper or through portals.
- ERA posting: Auto-matches payments to claims, applies adjustment codes, and flags denials for review. Unmatched lines still need a person to resolve them.
- Manual posting: Necessary when no ERA is available. It takes more time and carries a higher risk of keying errors, so it benefits from a second-person check.
Payer-specific enrollment and file rules vary, so confirm the details with each payer before changing your process.
How do posting errors hide denials?
Posting errors hide denials when a denied or underpaid line is recorded as fully paid, written off as a contractual adjustment, or applied to the wrong claim. The balance disappears from your A/R aging report, so no one follows up and the revenue is lost without anyone noticing.
Common ways this happens:
- Over-adjusting: A denial code is posted as a contractual write-off instead of being routed to denial work.
- Misapplied payments: A payment lands on the wrong patient, date of service, or line item, leaving the correct claim open and another one falsely closed.
- Ignoring remark codes: Reason and remark codes on the ERA or EOB explain why a line paid less than expected, and skipping them hides the pattern.
- Bundled payments: Multi-line payments posted as a single total can mask a short-paid line.
This is why posting and denial management should share the same data and the same reason codes.
| Check | What to confirm | Why it matters |
|---|---|---|
| Payment match | Payment applied to the correct patient, claim, and line | Prevents false closures and open balances |
| Adjustment codes | Contractual write-offs match the payer's fee schedule | Exposes underpayments |
| Denial routing | Denied lines flagged to a work queue, not written off | Keeps recoverable revenue visible |
| Patient responsibility | Copay, deductible, and coinsurance transferred correctly | Reduces patient statement errors |
| Deposit match | ERA batch totals equal the bank deposit | Catches missing or duplicate funds |
| Suspense balances | Unapplied funds cleared on a schedule | Keeps A/R reports accurate |
How should deposits be reconciled?
Reconcile deposits by matching every bank deposit or EFT to the payments posted in your billing system for the same period, and investigate any difference. Reconciliation confirms that money received equals money posted, and it catches missing remittances, duplicate posts, and unapplied funds.
A simple reconciliation routine:
- Pull the bank or clearinghouse deposit report for the period.
- Total the payments posted in your billing system for the same payer and date range.
- Match each deposit to its ERA or EOB batch.
- Investigate variances, including recoupments, takebacks, and held funds.
- Clear unapplied or suspense balances on a set schedule instead of letting them age.
How often you reconcile depends on your volume, but waiting until month-end makes variances harder to trace.
What should a posting quality check include?
A posting quality check should verify that payments, adjustments, and patient responsibility were applied to the correct claim lines and that denials were routed for follow-up. Checking a regular sample of posted batches catches recurring errors before they distort your reports.
Use the checklist below to review posted batches. Review a sample from each major payer, since errors often repeat by payer and by posting staff member. Track the error types you find so training and process fixes target the real causes.

Frequently asked questions
What is an EOB in medical billing?
An EOB (explanation of benefits) is the payer's statement showing what was billed, allowed, paid, adjusted, and owed by the patient. Practices use it to post payments manually when an electronic remittance is not available.
Who is responsible for payment posting?
Practices either assign posting to billing staff or outsource it to a billing company. Whoever owns it should also review denials and underpayments, since posting is where those problems first become visible.
Can posting errors affect patient statements?
Yes. If insurance payments or adjustments are applied incorrectly, the patient responsibility amount can be wrong, which leads to confusing statements, disputes, and delayed patient payments.
How does payment posting relate to A/R follow-up?
Accurate posting determines what stays open in your A/R. If posting is wrong, aging reports mislead your team, and unpaid or underpaid claims may never reach the follow-up queue.
