▼CO 97 Denial Code: Description, Causes, and Solution
When the benefit of a service is already included in the payment of another procedure, the insurer denies the claim. This denial code is referred to as CO 97. It is caused by bundling rules and missing modifiers. The practice can identify a CO 97 denial on the Explanation of Benefits (EOB) details.
However, this denial code leaves a negative impact on the cash flow of a practice. Therefore, applying proper modifiers and reviewing bundling policies is the key to fixing CO 97 denials.
What is the CO 97 Denial Code?
According to the Centers for Medicare & Medicaid Services, a CO 97 denial code indicates that the payment for a billed service is denied when it is already included in another reimbursed service.

Common Causes of CO 97 Denial Code
Unbundling Errors
When insurers consider multiple procedures as a single comprehensive package, it is referred to as a bundled service. The payer denies the claim under CO 97 denial code if the providers bill the services separately. This leads to unbundling errors.
Duplicate Billing
When a provider bills the same service a couple of times unintentionally, the payer denies the duplicate claim. It falls under CO 97 if the insurer treats the secondary claim as bundled.
Global Period Issues
A global period is the timeframe that includes post op visits in the original payment. If a provider bills separately for routine follow-up visits, the insurer denies it. That is because the payers consider it a bundled surgical package, hence it falls under the CO 97 denial code.
Incorrect Coding
The use of incorrect or outdated codes mismatches the services. These codes misalign with the payer-specific rules, causing CO 97 denial. That is because the service rendered falls under another reimbursed code in the payer system.
Specimen Collection
Most of the payers consider specimen collection as a part of the laboratory test payment. When the providers bill the specimen collection separately, it results in the CO 97 denial.
Failure to Use Add-On Codes
The add-on codes represent the additional procedures performed with the primary service. These procedures are not to be billed separately. If the providers bill them alone, it triggers CO 97 denial. Therefore, it is essential to include add-on codes with the original rendered procedure.
Specific Surgical Supplies
Most of the surgical supplies are included in the primary procedure payment. If the providers attempt to bill those supplies separately, they result in CO 97 denials. Such supplies include gloves, injections, catheters, and many more.
Multiple Procedures without Proper Sequencing
When multiple procedures are performed on the same patient, it is important to apply proper sequencing. This determines which procedures are reimbursable.
Failure to do so results in the overlap where the insurer considers some procedures a part of others. All leading to CO 97 denials.
Therapy and Rehab Services Overlap
Therapy or rehab services usually consist of multiple sessions. Billing them close together sometimes leads the insurer to think of the other as a duplicate. Therefore, it is important to provide proper documentation for each service or session.
Otherwise, the insurer denies separate payment under CO 97 denial.
How to Identify a CO 97 Denial on Your Claim?
Check Explanation of Benefits (EOB)
Explanation of Benefits is the first place to check for a CO-97 denial claim. If the provider bills two separate services on the same day, the insurer usually thinks of it as a collective procedure. Therefore, it is important to look at EOB to see if there is CO 97 listed next to any service.
Identify Related Paid Services
CO 97 often refers to the payment that is already made under another service. Therefore, if the provider looks over other related paid services, they will be able to identify which service the denied claim is included in.
Use Clearinghouse
Clearinghouse is an effective way of identifying potential CO 97 denial before the insurer does. It catches the claim, which seems to be a part of another procedure. Adding a modifier helps prevent the denial.
Compare Billed vs Allowed Amounts
If the allowed amount of some medical procedure is 0$, it leads to the CO 97 denial. Therefore, comparing the billed vs allowed amount will confirm that the service is already covered under something else.
Audit Related Procedures
Sometimes, two related services are considered one under billing. The CCI (Correct Coding Initiative) tool helps to check if the denied procedure is already covered under a similar service.
Therefore, by auditing the related procedures, the practice will be able to identify the cause of CO 97 denial.
Review Documentation for Medical Necessity
If a service is denied because the payer thinks it is already covered under some other procedure. The practice needs to review and show the proper documentation that shows medical necessity. This will determine whether the service was separate or not.
If there is a clear reason in the notes, the CO 97 denial will not be justified.
Consult the Payer Policy for Bundling Rules
Every payer has a different policy regarding bundling. It is important to check their rules beforehand to see if what you billed is considered included. A couple of procedures that are considered bundled in one payer’s rule are sometimes billed separately for another insurer.
Ensure Proper Sequencing
Proper sequencing and the right order are the key to avoiding CO 97 denial. If the practices submit add-on codes alone, the insurer denies it under CO 97. Therefore, it is important to make sure the main service is listed first. After that, all the bundled services need to be marked as add-ons.
How to Fix the CO 97 Denial Code?
Analyze Denial Reason in Depth
There are several reasons why the claim is denied under CO 97. Therefore, to fix the denial code, it is important to analyze the reason in depth. The practice will need to figure out whether the procedure was really a separate service.
Reading the details of EOB (Explanation of Benefits) helps identify the core denial reasons of a claim.
Add Correct Modifiers
Sometimes, when the procedures are done on the same day, the insurer usually identifies them as one. So if two procedures are truly separate and distinct from one another, adding the correct modifier fixes it.
The providers need to add the right modifier (a short code) along with the CPT code. This helps explain why the services need to be paid separately.
Clear Explanation in Appeal Letter
If the practice is writing an appeal for a claim that needs to be paid separately, the letter has to contain proper documentation. It also needs to explain the reason clearly. This helps support your appeal letter to the insurer.
Monitor Reprocessed Claims for Resolution
Sending in the appeal letter is not the end. The practice needs to monitor reprocessed claims regularly until they’re fully processed. This helps ensure that the appeal claim will get paid.
Follow up Promptly on Outstanding Appeals
If there is no response to the outstanding appeals, the practice will need to follow up immediately. Waiting for a longer time risks missing the appeal deadlines. The need for a follow-up usually arises after 30 days of an unanswered appeal.
Analytics to Prevent Repeat Denials
Tracking the previous CO 97 denials helps prevent the future ones. The practices need to look for similar patterns to fix the root cause. This helps the claim from the CO 97 denial from the same previous reasons.
Prevention Strategies for CO 97 Denials
Conduct Regular Staff Training
The practices need to conduct regular staff training to avoid CO 97 denials. This helps in identifying how and when the services are bundled. Learning the bundled services will automatically reduce mistakes that lead to CO 97 denial.
Pre-submission Claim Scrubbing
Using claim scrubbing tools before submission helps identify common triggers for CO 97 denial. It helps the practice to check the documentation and add a modifier if needed.
Verify Global Periods
When billing for the services after a surgery, make sure to check if they fall within the global period. Verifying the global period ensures that the practice only submits claims for unrelated services. This helps reduce the chances of CO 97 denial.
Maintain Accurate Records
Maintaining a detailed and accurate record of each claim helps prevent denial. If the insurer denies a claim under CO 97, the practice will be able to file for an appeal with reasonable documentation.
Conduct Periodic Internal Audits
Periodic internal audits catch the repeated patterns of CO 97 denials. It helps reduce the chances of denial in the future by avoiding the same mistakes.
How CO 97 Denial Affects Cash Flow?
Delayed Reimbursements
A CO 97 denied claim does not pay the provider unless the claim is corrected. This delay slows down the reimbursements. It also affects the ability to cover the daily expenses of a small clinic.
Increased AR Aging
Denied claims remain in the Accounts Receivable if not resubmitted quickly. A growing number of unpaid CO 97 claims increases the AR aging. This affects the cash flow of a practice, reducing monthly collections.
High Administrative Costs
Fixing the CO 97 denial requires extra staff and time. They recheck codes, review documentation, file appeals, and take timely follow-ups. This administrative cost reduces the overall profit of the practice.
Impact on Provider’s Operational Budget
The constant cash flow disruptions due to CO 97 denial affect the operational budget of a practice. It includes the provider’s ability to invest in technology and pay their staff on time.
