Payment Posting

When your revenue cycle can't afford to stop.

Why Payment Posting Matters More Than It Sounds

Payment posting is the process of recording what a payer or patient paid, what was adjusted off, and what balance remains. Done correctly, it keeps your accounts receivable accurate and your revenue cycle metrics trustworthy. Done incorrectly, it quietly distorts everything downstream.

A practice can have strong claims and good follow-up and still underperform on collections -- if posting errors are masking the real picture. Bad posting does not just create accounting problems; it causes the practice to stop chasing money it is owed.

Payment posting accuracy is the foundation of an accurate net collection rate. If adjustments are posted incorrectly, your metrics will look fine even when revenue is being left on the table.

Key Terms to Know

ERA
Electronic Remittance Advice. The electronic file a payer sends explaining exactly what they paid, adjusted, and why. Loads directly into your practice management system.
EFT
Electronic Funds Transfer. The actual money deposited directly to your bank account, paired with the ERA.
EOB
Explanation of Benefits. The paper version of remittance information. Requires manual posting when ERA is not available.
CARC
Claim Adjustment Reason Code. Explains why a payment was reduced or denied. Industry standard codes used across payers.
RARC
Remittance Advice Remark Code. Adds detail to a CARC -- provides additional context for the action taken on a claim.
Line-item posting
Posting payment to each individual service line on a claim, rather than a lump sum to the account. Required for accurate tracking.

How Payment Posting Works

When a payer processes your claim, they send back either an ERA (electronic) or an EOB (paper) that shows exactly how they handled each line item: what they paid, what they adjusted contractually, and what they are sending back to the patient or a secondary payer.

Your billing team posts this information into the practice management system line by line. Each service gets its own entry -- not a total for the whole claim. This is called line-item posting, and it is non-negotiable for accurate revenue cycle tracking.

  • If the ERA loads electronically, most transactions post automatically -- but someone still needs to review exceptions, denials, and underpayments
  • If using paper EOBs, posting is manual and requires a skilled reader who understands the codes
  • All payments should be posted within 24 hours of receipt

Types of Adjustments

Not every dollar difference between your charge and what you collected is the same thing. Adjustments fall into two categories:

  • Contractual adjustments -- the difference between your charge and what the payer is contracted to allow. This is expected and legitimate. It is not lost revenue.
  • Non-contractual adjustments -- write-offs that are not part of your payer contract. These include bad debt, errors, and denials that were adjusted off instead of appealed. These represent potential revenue that was not recovered.

When a denial that could have been appealed gets written off as a contractual adjustment, it disappears from your AR and your metrics look clean -- but the practice lost real money. Sloppy adjustment coding hides revenue leakage.

What Happens When Posting Goes Wrong

The same claim, posted three different ways, produces three very different outcomes. This example uses a $900 charge where the payer allowed $475 and paid $150 initially, with $85 transferred to patient responsibility:

Posted Correctly
Team catches the underpayment, appeals, collects the remaining amount. Patient billed and pays their $85.
NCR: 100%
Posted Incorrectly (Over-adjusted)
Entire remaining balance written off as contractual. No appeal filed. Account closed.
NCR: 34%
Posted Incorrectly (Balance-billed)
Patient balance-billed incorrectly. Patient disputes, refuses to pay. Written off 18 months later as bad debt.
NCR: 38%

Correct posting in Scenario 1 results in $315 more cash collected than either incorrect scenario -- and an accurate net collection rate the practice can actually trust.

Posting Denials Correctly

When a claim is denied, there is a right way and a wrong way to handle the posting. The recommended approach:

  1. Post the denial to the account using the CARC and RARC codes from the ERA or EOB
  2. Maintain the balance on the account -- do not adjust it off yet
  3. Flag the transaction for follow-up by routing it to the appropriate work queue
  4. Let the biller review and determine whether to appeal, correct and resubmit, or adjust off with proper justification

This keeps denied claims visible in your AR where someone will work them -- rather than buried under a write-off code where they disappear.

Posting Standards to Know

  • Post within 24 hours of payment receipt -- delays cause patient statements to go out without reflecting payments already made
  • Line-item post every claim -- never lump a total to the account
  • Use correct adjustment codes every time -- consistency is what makes your management reports useful
  • Enroll with every payer offering ERA and EFT -- reduces manual work and accelerates reconciliation
  • Separate duties -- the person collecting should not be the person posting or reconciling
  • Work credit balances within 60 days of discovery
