Payment Posting in Medical Billing: A Practical Guide

A payment made from an insurance company may seem like the final phase of a billing cycle for a medical practice. This is not necessarily true, as there is much work that has to be done after the receipt of the payment. This payment must be matched to a specific claim, logged into the billing cycle, and compared to what the payer has submitted. The payer may have reduced the amount of payment, denied any treatment, or even shared some costs with the patient.

This is where payment posting in medical billing comes in. The process of payment posting aids healthcare organizations in keeping their financial information accurate and helps them to identify what happened to their claims. Payment posting is also useful in identifying missing payments and adjustments and determining which accounts need more follow-up.

Medical coding knowledge can be useful during this process, too. Such acronyms as CPT, ICD-10-CM, HCPCS, CARC, and RARC are frequently encountered while dealing with claim and remittance processes. It is helpful for a biller to understand what each of them means in order to identify possible issues and direct them to appropriate departments. This guide will cover the steps of payment posting, describe the terminology of billing practice, and discuss how to avoid pitfalls.

 What Does Payment Posting Mean in Medical Billing?

Payment posting refers to the documentation of payments and any adjustments to finances within the medical billing system after the claim processing or payments have been made by the patient. Such entries might include insurance payments, patient payments, adjustments due to contract, refunds, and other applicable adjustments.

For instance, assume that a medical practice bills for an office visit. This bill is processed by the insurance company and a partial payment is made based on the amount that was allowed. Contractual adjustment takes into account the reduction of the charges for the medical practice, whereas some portion goes towards the deductible or coinsurance of the patient. The payment posting professional enters this information into the account as per the payer’s decision. Without payment posting, the practice will find it difficult to know if the payment is done correctly or not.

The purpose of payment posting is not simply to enter payment amounts. It is to make sure the financial outcome of each claim is recorded accurately and can be verified.

Why Does Payment Posting Matter to a Medical Practice?

Payment posting might happen behind the scenes, but mistakes can affect several parts of a practice’s operations. 

Accurate patient balance

For example, the client may have made a copayment; however, it was not recorded into the system. The system can reflect that there is still an outstanding balance, which may result in sending a statement. Accurate posting helps prevent these situations.

 Makes insurance discrepancies easier to find

Sometimes the amount received does not appear to match the payment information supplied by the payer. The difference may involve multiple claims, an adjustment, a missing remittance record, or a transaction that needs further investigation. Making sure that payments reconcile allows the billing department to know why there is a variance.

It facilitates accounts receivable follow-ups

Once the payments have been entered, the group is able to identify which of the accounts that still have pending amounts. This may be because there is still work being done by the secondary insurance, or even just following up with the payer.

Identification of issues related to claims

If there is a remittance report of a denied claim or one with different treatment from what was expected, this will help the team in identifying which area should be blamed for the error – billing, coding, denial, etc.

Improve financial reporting

There are managers who use the data in payments in order to perform various assessments. Incorrect entries will affect this process

Types of Payment Posting in Medical Billing

Payment posting can be grouped by the source of the money or the method used to record the transaction.

Type What it involves
Insurance payment posting Recording payments received from health plans
Patient payment posting Recording payments such as copayments and other patient payments
Electronic payment posting Importing payment information from compatible electronic remittance records
Manual payment posting Entering or verifying payment information by hand
Secondary insurance posting Recording the outcome of a secondary payer’s processing
Adjustment posting Recording applicable contractual adjustments and other financial adjustments
Refund and recoupment posting Recording appropriate refunds, reversals, or payer recoveries

These categories can overlap. For example, an insurance payment may be posted electronically, while a patient payment is entered manually.

Electronic vs. manual payment posting

Posting electronically may result in savings of time, as compatible software will allow importing data from an Electronic Remittance Advice (ERA). This eliminates the need for repetitive data entry and may lead to a higher level of consistency in payment processing.

Nevertheless, automatic processing will not guarantee that all transactions may be posted automatically. Incomplete data, missing payments, unexpected adjustments, and unsuccessful imports may require a certain involvement of staff members. Manual processing will prove to be necessary when no electronic data is available for import.

This decision will depend on several factors.

How Does Payment Posting Occur?

Even though the billing process may vary, the typical payment posting process is quite standard across all organizations.

Step 1: Receipt of the Payment

An EFT, check, or any other mode of payment approved by the practice is received from the payer. The relevant remittance details are also gathered in this step. Remittance details explain how the payment was made after processing the claim.

Step 2: Matching payment with remittance entry

Before entering the transaction, the specialist ensures that the payment matches the remittance entry. The criteria for matching payment with the remittance will vary depending on the system used.

For example, the criteria could include the payer’s name, the amount of payment, the date of payment, the trace number, etc. The EFT moves the funds while ERA describes how the claims were processed by the payer. Both documents have different uses and, therefore, need to be matched accordingly.

Step 3: Review the claim details

The next step is to examine how the payer handled the claim.

The specialist may review:

  • Submitted charges and allowed amounts
  • Insurance payments
  • Deductible, copayment, and coinsurance amounts
  • Contractual adjustments
  • Denied or partially paid services
  • Claim-level and service-line adjustments

This review helps the team understand the financial outcome before recording the transaction.

Step 4: Record the payment

Once the information has been checked, the payment is posted to the appropriate claim and patient account. Other systems accomplish much of the task in an automatic fashion. Otherwise, the specialist inputs the information manually. In both cases, it is important that the information posted is accurate and that there have been no duplicate payments entered by the team.

Step 5: Apply the appropriate adjustments

The specialist records the adjustments supported by the remittance information and applicable billing requirements. For instance, a contractual adjustment can be used to lower the fee charged by the provider in accordance with the contractual obligations. The patient’s responsibility can be connected to a deductible or co-insurance payment. The group should not consider all uncollected payments as a write-off.

Step 6: Investigation of Denials and Unusual Payments

If at any time the payer denies the service and approves the other lines in the same claim, the billers need to know which one is denied and the justification for it. The investigation whether it needs a coding review, claim adjustment, documentation verification, payer inquiry, reconsideration, or appeal, would depend on the case. The appropriate step to take will depend on the true reason for the denial.

Step 7: Balance Review

All the payments and adjustments have now been made in the claim; therefore, the balance is calculated. This balance can either be owing from the patient or from the secondary insurance. Further actions to take will depend on the payer decision, the details of coverage, policies, and history of the case.

Step 8: Reconciling the batch of postings

Lastly, the batch of transactions is compared against the total for payment and remittance. All discrepancies should be followed up and recorded. After all the necessary reconciliations have been made, the batch will be ready for posting.

Medical Coding Terms Every Payment Posting Specialist Should Know

Medical coding and payment posting are different jobs, but they often intersect during claim review.

Coders assign diagnosis and procedure codes based on the medical documentation and applicable guidelines. Payment posting specialists record the payer’s financial decision and identify transactions that need further investigation.

Here are some coding terms that commonly appear in medical billing workflows.

1. ICD-10-CM: Diagnosis codes

ICD-10-CM stands for International Classification of Diseases, Tenth Revision, Clinical Modification. It is used to report diagnoses and medical conditions on healthcare claims in the United States.

Examples include:

Code Description
E11.9 Type 2 diabetes mellitus without complications
I10 Essential (primary) hypertension
J06.9 Acute upper respiratory infection, unspecified

The above are coding examples for diagnosis codes. They are not coding instructions for the encounter in question. It will depend on the provider’s documentation and the appropriate coding guidelines. In payment posting, diagnoses can be scrutinized in case of a denial and/or inappropriate payor action. In such cases, if any issues with the coding arise, then the matter should be referred to the coding specialists.

2. CPT: Procedure and service codes

CPT refers to Current Procedural Terminology. This refers to the medical procedures or professional services that are billed using codes. For instance, codes 99213 and 99214 refer to the office or other outpatient evaluation and management services for established patients.

It depends on what the applicable CPT rules are and how well the services have been documented. Never use any code just because it will pay more money. The payment posting people can look at CPT details to find out whether any service lines were paid for, denied or adjusted. If the payment does not seem to match the billed service, further coding or payer policy research might be required.

3. HCPCS: Supplies, equipment, drugs, and other services

HCPCS is an acronym that means Healthcare Common Procedure Coding System.

HCPCS Level I entails CPT codes whereas HCPCS Level II entails other codes apart from CPT that pertain to medical supplies, durable medical equipment, medications and other items in healthcare. The codes could be useful in examining claims regarding some equipment, medical supplies or particular items and services.

In case of a service line denial or payment not in conformity with the expectations, there may be a need to review the code, documentation and requirements of payers.

4. CARC: Claim Adjustment Reason Code

The CARC stands for Claim Adjustment Reason Code. It gives reasons as to why there was an adjustment in the claim or service-line payments by the insurance payer. For instance, the adjustment could be related to the deductible, coinsurance, missing information, or other issues relating to claim processing. The specialist should take time to examine the particular reason code and its associated information before making any decision as to whether further action should be taken.

5. RARC: Remittance Advice Remark Code

Remittance Advice Remark Code is the full meaning of RARC. This gives more information on the claim or the adjustment done to a claim. A remark code can help to understand the information that is lacking or an action that needs to be taken. When analyzing remittance advice, the remark code should be analyzed along with the adjustment reason and adjustment group codes.

Other common medical billing abbreviations

Abbreviation Meaning
ERA Electronic Remittance Advice
EOB Explanation of Benefits
EFT Electronic Funds Transfer
NPI National Provider Identifier
POS Place of Service
DOS Date of Service
AR Accounts Receivable
RCM Revenue Cycle Management
E/M Evaluation and Management

Understanding these terms will enable the payment posting professionals to speak effectively to the medical billers and coders among other revenue cycle professionals.

For authoritative sources, refer to the CMS guidance on payments and remittance advice and the ICD-10-CM/CPT guides from CDC/AMA.

A Practical Example: How Payment Posting Works

Let’s say a physician’s office submits a claim with a total charge of $200.

After processing the claim, the insurance company reports the following amounts:

Claim detail Amount
Submitted charge $200
Contractual adjustment $50
Insurance payment $120
Patient responsibility $30
Total accounted for $200

The payment posting specialist posts the insurance payment of $120, the contractual adjustment of $50, and confirms the patient’s financial responsibility of $30 based on the remittance advice.

In case the remainder of the patient balance can be transferred to the proper workflow, the above mentioned process can take place only after verification of the payer’s explanation and compliance with other requirements.

Now assume that the payer rejects the service. The payment posting specialist looks at the remittance advice and discovers the reasons for denial. When the denial is due to coding, documentation or possible mistakes, the claim should be forwarded to the responsible group.

This is the reason why the process of payment posting cannot consist only of entering the amount. The team needs to understand what the player says and what action needs to be taken.

The above case serves as an illustration but the reimbursement depends on many factors.

Common Payment Posting Errors and How to Avoid Them

Even an experienced billing team can make mistakes when processing a large volume of transactions. The important thing is to have checks in place to catch and correct them.

Common mistake Why it matters How to reduce the risk
Posting a payment to the wrong account The patient balance becomes inaccurate Verify patient and claim identifiers
Entering the wrong amount The account may not reconcile Compare posted totals with remittance records
Posting the same payment twice Financial records may show an incorrect balance Check transaction history before posting
Applying an incorrect adjustment The remaining balance may be wrong Review adjustment codes and payer information
Overlooking a denial Follow-up may be delayed Use an exception queue for denied claims
Missing secondary insurance follow-up Further processing may be delayed Check payer sequence and coordination-of-benefits information
Ignoring unmatched payments Financial differences remain unresolved Track each discrepancy until it is addressed

Why adjustment codes deserve attention

A contractual adjustment, a patient-responsibility amount, and a denied service are different outcomes. They should not all be treated as routine reductions.

For example, a contractual adjustment may be appropriate under the provider’s agreement with the payer. A denial, on the other hand, may require further review depending on the reason provided.

Understanding the difference helps the billing team avoid unnecessary write-offs and identify claims that may need additional attention.

Payment Posting Roles and Responsibilities

The exact division of work varies from one organization to another. In a smaller practice, one employee may handle several billing functions. Larger organizations may have separate teams for payment posting, coding, denials, and accounts receivable.

Payment posting specialist: Records payments, applies supported adjustments, matches remittance records, and identifies discrepancies.

Medical biller: Reviews claim status, addresses billing errors, and manages claim follow-up.

Medical coding specialist: Reviews diagnosis and procedure coding when a potential coding issue is identified.

Denial management specialist: Investigates denied claims and coordinates appropriate corrections, reconsiderations, or appeals.

Accounts receivable specialist: Tracks outstanding balances and follows up on unpaid claims.

Billing manager or RCM supervisor: Reviews posting accuracy, reconciliation results, unresolved issues, and team performance.

Clear responsibilities help ensure that problems are sent to the right person instead of remaining unresolved in the billing system.

Best Practices for Improving Payment Posting

A good payment posting process should be accurate, consistent, and easy to monitor.

Use electronic transactions where appropriate

ERA and EFT workflows can reduce repetitive work and make payment reconciliation easier. Practices should ensure that their software is configured correctly and that staff know how to handle failed imports and unmatched transactions.

Create a consistent posting procedure

Document how payments are received, matched, posted, adjusted, and reconciled. Staff should also know how to handle exceptions and who is responsible for resolving them.

Keep track of unresolved issues

Maintain a process for monitoring missing remittance records, unexplained adjustments, and payment discrepancies. Assign ownership to each issue and record the steps taken to resolve it.

Train staff on coding and remittance terminology

Payment posting professionals do not necessarily need to perform medical coding, but they should understand the basic terminology used in claim processing.

Knowing the difference between CPT, ICD-10-CM, HCPCS, CARC, and RARC can make it easier to recognize potential problems and communicate with the coding team.

Monitor performance regularly

A practice can review measures such as posting accuracy, unmatched payments, duplicate transactions, unresolved variances, and the time taken to post payments.

The most useful measures are those that help management identify recurring problems and improve the workflow.

Maintain appropriate financial controls

Limit access to billing systems according to job responsibilities and retain appropriate transaction records. Practices should also establish review procedures for refunds, reversals, and significant adjustments.

How Payment Posting Supports Revenue Cycle Management

Payment posting gives a medical practice a clearer picture of what happened after claims were submitted to insurance companies.

Once payments and adjustments are recorded, the billing team can identify outstanding balances, monitor accounts receivable, review payer discrepancies, and determine which claims need further work.

For example, if a practice notices repeated differences between expected and actual payments from a particular payer, the team can investigate the relevant remittance records and contract terms. If the pattern appears to involve coding or documentation, the issue can be referred for further review.

Accurate payment posting does not guarantee that claims will be paid or eliminate denials. It does, however, provide reliable information that helps the practice decide what to do next.
