What is adjustment reason code 96?
Adjustment code 96 means non-covered charge(s) under the patient's insurance plan.
Insurance companies use this Claim Adjustment Reason Code (CARC) when a billed service or supply is not part of the member's benefit package or is excluded by the policy. It always appears with a group code that assigns financial responsibility and is usually paired with a Remittance Advice Remark Code (RARC) for specific details.
Group Codes for Code 96
- PR-96 (Patient Responsibility): The cost shifts to the patient because the service is not covered by their plan. Providers can bill the patient if proper notice (like a Medicare ABN) was given beforehand.
- CO-96 (Contractual Obligation): The provider must write off the charge and cannot bill the patient because of a contractual agreement or failure to secure proper upfront authorization/waivers.
- OA-96 (Other Adjustment): Used for general adjustments, often involving coordination of benefits or secondary payers.
How to Resolve It
- Check the Remark Code: Look at the accompanying RARC (such as code N130 or N56) to find the exact operational reason for the denial.
- Verify Patient Benefits: Check if the service was a true policy exclusion or if it required a specific modifier (like the GY modifier for Medicare statutorily excluded services).
- Correct and Resubmit or Appeal: If it was a coding mistake, fix the claim and resubmit. If documentation was missing, submit a redetermination request with the proper medical records.
What does code 96 mean?
The meaning of "96 code" depends heavily on the context, most commonly referring to a medical billing denial or a police radio code.
1. Medical Billing (CO-96 / PR-96)
In healthcare administration, CO-96 or PR-96 is a Claim Adjustment Reason Code (CARC) meaning non-covered charge.
- Meaning: The insurance company refuses to pay because the billed service or procedure is not included in the patient’s current benefit plan.
- Prefix difference:
- CO-96 stands for Contractual Obligation, meaning the provider generally must write off the charge and cannot bill the patient unless specific advance notices (like an ABN) were signed.
- PR-96 designates Patient Responsibility, meaning the patient may be billed directly for the non-covered service.
2. Police and Emergency Radio (10-96)
In law enforcement and emergency services, 10-96 is a ten-code whose exact definition varies by region and agency:
- Mental Subject / Detained Person: Many police departments use 10-96 to indicate a person with mental health issues or someone who needs to be detained/evaluated.
- Medical Emergency: Some emergency medical services (EMS) or police agencies use 10-96 to signal a serious injury or a subject requiring immediate medical attention.
How to resolve co 96 denial?
To resolve a CO 96 "non-covered charge" denial, review your remittance advice, verify the patient's actual policy benefits, and correct any coding errors or file an appeal as detailed in the AnnexMed CO 96 Guide.
Step 1: Review the Remittance Advice (RA)
- Check the Group Code (CO means contractual obligation, meaning you cannot easily bill the patient).
- Look at the Remittance Advice Remark Codes (RARCs) paired with code 96 to find the exact reason for non-coverage.
- Identify if it is a coding mismatch, an exhausted benefit limit, or a true policy exclusion.
Step 2: Verify Coverage and History
- Check if the specific CPT (Current Procedural Terminology) code was paid by this payer for this provider before.
- Confirm whether a prior authorization or referral was required but missing from the initial claim.
- Call the insurance provider to confirm if the service is excluded or if they need extra documentation.
Step 3: Take Corrective Action
- Resubmit the claim: If you find a missing modifier, wrong place of service, or incorrect code, fix it and send a corrected claim right away.
- Request reprocessing: If the payer made a mistake on a service that is clearly covered under the plan, ask them to reprocess the claim and note the call reference number.
- File an appeal or reconsideration: Submit clinical notes or proof of medical necessity if the service requires clinical review.
- Write off the balance: If the service is truly not covered and no prior authorization or waiver (like an ABN) was signed by the patient, you must write off the charge per your contract.
What does denial code 96 mean on a Blue Cross Blue Shield claim?
A Blue Cross Blue Shield (BCBS) denial code 96 means non-covered charge(s), indicating that the service or item billed is not included under the patient’s insurance benefit plan.
What Code 96 Means
Code 96 is a Claim Adjustment Reason Code (CARC). It always comes with a Remittance Advice Remark Code (RARC) to explain the exact reason for the non-coverage. You will usually see one of two prefixes:
- PR-96 (Patient Responsibility): The service is not covered by the plan, and the cost may legally be billed to the patient (if proper upfront notice, like an advance waiver, was given).
- CO-96 (Contractual Obligation): The service is not covered, but the provider is contractually obligated to write off the charge and cannot bill the patient (unless a signed waiver or Advance Beneficiary Notice was obtained beforehand).
Common Causes
- Policy Exclusions: The specific treatment or procedure is explicitly excluded from the patient's insurance policy.
- Coding Errors: Incorrect CPT/HCPCS codes or missing modifiers were used, making the procedure look non-covered.
- Medical Necessity Mismatch: The diagnosis code (ICD-10) does not match the procedure code according to BCBS coverage rules.
- Missing Prior Authorization: The service required prior approval from BCBS before it was performed.
How to Resolve It
- Check the Remark Codes: Look at the accompanying RARC or Explanation of Benefits (EOB) to find the precise sub-reason for the denial.
- Review the Coding: Verify that the procedure and diagnosis codes are accurate and include any required modifiers.
- Verify Prior Authorization: Confirm whether an authorization was needed and if it was submitted.
- Resubmit or Appeal: If it was a coding error or missing documentation, correct the claim and resubmit. If the service genuinely lacks coverage or medical necessity guidelines weren't met, you can file a formal clinical appeal with supporting medical records. For further guidance on fighting incorrect denials, refer to detailed breakdown resources like Why Insurers Use PR 96 Denial Code.
What are adjustment codes?
Adjustment codes, known formally as Claim Adjustment Reason Codes (CARCs), are standardized alphanumeric labels used in medical billing to explain why an insurance payment differs from the amount billed.
Insurance companies and health plans place these codes on an Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA) to show why a claim was denied, reduced, or altered.
How Adjustment Codes Work
- What happened (CARCs): Three-character codes that state the financial reason for a payment change, such as a service not being covered or a duplicate submission.
- Who pays (Group Codes): Attached prefixes that show financial liability. Common groups include CO (Contractual Obligation written off by the provider) and PR (Patient Responsibility for deductibles or copays).
- Why it happened (RARCs): Remittance Advice Remark Codes often accompany CARCs to provide extra non-financial details or next steps.
Common Examples
- CO-45: The charge exceeds the allowed or contracted fee schedule maximum.
- PR-1: The amount applies to the patient's deductible.
- CARC 96: Non-covered charges based on the benefit plan.
CO 96 Denial Code: What It Means and How to Fix It
What does adjustment reason code 96 mean in Medicare billing?
Claim Adjustment Reason Codes for adjustment reason code 96 indicate non-covered charge(s), meaning the billed service or procedure is not part of the patient's insurance benefit plan.
Understanding the Group Codes
Code 96 is paired with a group code that assigns financial responsibility:
- CO-96 (Contractual Obligation): The provider is usually obligated to write off the charge because it was not a covered benefit and proper advance notice (such as an Advance Beneficiary Notice or ABN) was not given to the patient.
- PR-96 (Patient Responsibility): The patient may be billed for the service, often occurring when a service is statutorily excluded or specific agreements/notices are in place.
- OA-96 (Other Adjustment) / PI-96: Often tied to coordination of benefits, secondary payer rules, or internal payer policy adjustments.
How to Resolve Code 96
- Check the Remark Codes: Code 96 must always be accompanied by a Remittance Advice Remark Code (RARC) or NCPDP reject code explaining the specific reason (e.g., age limit, invalid code combination).
- Verify Coverage and Coding: Confirm if a coding error, missing modifier (like GY for Medicare statutory exclusions), or incorrect diagnosis-to-procedure mapping triggered the denial.
- Submit an Appeal or Correction: If coded incorrectly, correct the claim and resubmit. If it is a true non-covered benefit and proper patient financial waivers exist, shift the balance to the patient.
What does the PR 96 code mean in medical billing?
PR 96 is a medical billing denial code that means a billed service or charge is not covered by the patient's health insurance plan, and the financial cost is the patient's responsibility.
What the Code Means
- PR: Stands for Patient Responsibility, meaning the insurance company will not pay, and the patient may be billed for the balance.
- 96: Stands for Non-covered charge(s), meaning the specific treatment, item, or procedure is excluded from the patient's benefit plan or policy.
Common Causes
- Benefit exclusions: The service is simply not part of the insurance package.
- Missing authorization: A required prior approval was not obtained before treatment.
- Coding errors: The wrong procedure code (CPT) or diagnosis code (ICD) was submitted.
- Out-of-network care: The provider is not covered under the plan.
How to Resolve It
- Check the codes: Review the claim for correct coding or missing modifiers.
- Verify waivers: See if a signed Advance Beneficiary Notice (ABN) exists, which legally allows billing the patient.
- Appeal or write off: Submit an appeal with medical records if it was a payer error, or write off the charge if required by contract rules.
Is CO 96 patient responsibility?
No, a CO-96 denial code is not the patient's responsibility; it is a contractual obligation that the provider must write off.
What CO-96 Means
- Contractual Obligation (CO): The "CO" prefix means the insurance company's contract with the doctor or facility prevents them from billing you for the denied amount.
- Non-Covered Charge (96): The number 96 indicates that the specific service is not included in the patient's current insurance benefit plan.
- Provider Liability: Because of the CO tag, the healthcare provider must absorb the cost and cannot pass the balance to the patient. You can read more about these rules in the Etactics CO-96 Guide.
CO-96 vs. PR-96
It is easy to confuse CO-96 with PR-96 because they share the same number, but the letters change who has to pay:
- CO-96: Provider responsibility (write-off).
- PR-96: Patient responsibility (you may owe the balance). PR stands for "Patient Responsibility".
Special rules or separate benefit administrators (like in behavioral health) can sometimes cause confusion over which code applies, as detailed by Cipher Billing. Unless you signed a specific financial waiver or Advance Beneficiary Notice (ABN) before getting the care, a strict CO-96 means you do not owe the money.
Can you resubmit a rejected claim?
Yes, you can resubmit a rejected claim after fixing any errors.
How to Resubmit
- Identify the error: Look at the rejection message or code from the clearinghouse or payer to find the missing or incorrect data.
- Make corrections: Update the patient details, typos, billing codes, or missing fields in your billing software.
- Add reference numbers: If required by the payer, update the claim frequency code (often set to code 7 for a replacement/corrected claim) and include the original claim reference number or ICN.
- Resubmit: Send the corrected electronic or paper claim back to the insurance company.
Key Differences from Denied Claims
- Rejections happen before the claim enters the insurance system. They are un-adjudicated formatting or data errors that you can fix and resubmit immediately without an appeal.
- Denials are processed and formally rejected by the insurer. Those require a formal appeal process rather than a simple resubmission.
What are the top 5 denial codes in medical billing?
The top 5 most common medical billing denial codes are CO-16, CO-18, CO-29, CO-50, and CO-97. These codes are standardized as Claim Adjustment Reason Codes (CARCs).
1. CO-16: Claim Lacks Information
- What it means: The insurance payer needs more data or made a data entry error processing the claim.
- Why it happens: Missing attachments, invalid provider numbers, or blank fields.
- How to fix it: Add the missing information and resubmit the claim.
2. CO-18: Duplicate Claim/Service
- What it means: The payer received identical claims for the same service on the same date.
- Why it happens: Submitting a claim twice before the first one finishes processing.
- How to fix it: Check the claim status before resubmitting, and appeal only if the original was truly lost or denied incorrectly.
3. CO-29: Timely Filing Limit Exceeded
- What it means: The claim arrived past the insurance company's strict deadline.
- Why it happens: Delays in coding, credentialing, or waiting on primary insurance.
- How to fix it: Submit proof of timely filing (like an electronic transmission report) if you sent it on time. Otherwise, write off the charge.
4. CO-50: Not Deemed a Medical Necessity
- What it means: The payer says the diagnosis code does not support the procedure billed.
- Why it happens: Mismatched ICD-10 and CPT codes, or weak clinical documentation.
- How to fix it: Send medical records that prove necessity, or correct the diagnosis code if a more specific one applies.
5. CO-97: Service Bundled in Another Procedure
- What it means: The billed service is part of a larger, comprehensive procedure.
- Why it happens: Biling separate codes for individual steps of a surgery or test that should be billed under one umbrella code.
- How to fix it: Review National Corrective Coding Initiative (NCCI) edits, and add a valid modifier if the service was separate and distinct.
