OA 23 Denial Code

We understand that managing the complexities of medical billing requires precision and foresight. Understanding denial codes like OA 23 is crucial to optimize your reimbursement processes. This article explores the common reasons for the OA 23 denial code. We also uncover valuable strategies with which you can prevent them.

Read on to find out how Health Quest Billing is the answer to all your billing issues.

What is OA 23 Denial Code?

The OA 23 denial code is indicated whenever a reimbursement claim undergoes partial adjustment. This adjustment is made due to a prior payer’s adjudication. This means that the relevant medical service is already paid by a primary insurance company. Now, a secondary insurance company has sent the OA 23 denial code.

And it is adjusting its reimbursement accordingly. Here, OA is a group code that corresponds to specific adjustments made. These adjustments are made as a result of secondary insurance. Moreover, the number 23 indicates the reason for that adjustment.

Common Reasons for the OA 23 Denial Code

There can be various reasons as to why insurance companies deny claims with the OA 23 code. Here is an explanation for the major ones:

  • Incorrect Adjustments and Inadequate Documentation

A prior payer may make an error in processing your reimbursement claims. As a result, this code can be triggered due to the incorrect adjustment. This error can result due to either misinterpretations or miscalculations. This is what usually happens to claim details apart from system glitches. It is also possible that you provide either insufficient or incomplete documents.

Such documents can contribute to the code 23 attached with the relevant claims. There can be some necessary supporting documents missing as well. Your documents may not simply meet the requirements of insurers. All these instances can lead to claim denials or adjustments.

  • Non-covered Services and COB Issues

Another reason for the mention of code 23 is that the insurance plan of patients does not cover the relevant services. The reason for this can be policy limitations or exclusions. The service can also be simply deemed medically unnecessary.

In cases where patients have multiple coverages, coordination of benefits plays an important role. The code 23 can also be assigned in the presence of discrepancies or conflicts. They can be encountered during the COB process. As a result, they further cause adjustment issues.

  • Incorrect Coding and Filing Limits Exceeded

There can be certain errors in assigning codes as well. Some of the common ones include using the wrong codes or procedures. Such coding errors can also result in code 23. As a result, the codes and services mentioned on the relevant reimbursement claims do not match with each other. These mismatches can lead to payment discrepancies or denials.

Healthcare organizations have to abide by specific timeframes while submitting claims. Sometimes, the claims end up getting filed after the allowed time limit. As a result, they often get denied with the code 23. Insurance companies can deny such late submissions. They may also make adjustments based on the expiration of the timely filing window.

  • Duplicate Claims and Contractual Agreements

Some healthcare providers accidentally submit duplicate reimbursement claims for the same service. This error can also trigger code 23 from the relevant insurance companies. Those companies have appropriate policies set that aim to prevent such duplicate claims.

It is highly important as well because insurers may end up paying twice if they overlook the error. As a result, they have to identify the multiple claims as duplicate. Then, they either make adjustments or completely deny the subsequent one.

There are some contractual agreements as well that can cause code 23. These agreements are made between hospitals and insurance companies. Often, both parties found themselves in between discrepancies or violations of their agreed-upon terms. As a result, they commonly face payment and adjustment issues.

How to Avoid OA 23 Denial Code?

There are multiple strategies that you can adopt to avoid claim denials with the OA 23 code. We have compiled a list of the major ones for your convenience:
