Disclaimer
These policies serve as a guide to assist in the submission of accurate claims and to outline the basis for reimbursement if the service is covered by a member’s benefit plan. The determination that a service, procedure, product, or any other item submitted in a claim is covered under a member's benefit plan is not a determination of reimbursement. Services must meet authorization and primary coverage criteria or medical necessity guidelines appropriate to the procedure and diagnosis as well as to the member’s state of residence. Proper billing and submission guidelines must be followed. Industry standard, compliant codes on all claim submissions are required. Services should be billed with Current Procedure Terminology (CPT) codes, Healthcare Common Procedure Coding System (HCPCS) codes and/or Revenue codes. The codes denote the services and/or procedures performed. The billed code(s) are required to be fully supported in the medical record and/or office notes.

Unless otherwise noted within the policy, our policies apply to both participating and non-participating providers and facilities.

If appropriate coding/billing guidelines or current reimbursement policies are not followed, claims may be rejected or denied and there may be recoupment of payment.

As determined by Arkansas Blue Cross and Blue Shield, these policies may be superseded by applicable provider or state contract language, by applicable state or federal laws and regulations, or by other applicable state or federal requirements or mandates. We strive to minimize delays in policy implementation. If there is a delay, we reserve the right to recoup and/or recover claims payment to the effective date, in accordance with the policy. Policies will be reviewed and revised periodically when necessary. When there is an update, the most current policy will be published to the website. Notification of policy revisions will be published as an alert on the Availity Portal and quarterly in Providers News.
Description

This policy addresses general coding and billing guidelines utilized by Arkansas Blue Cross and Blue Shield to assist in consistent claim review process. Procedure code edits utilized for automated claims adjudication are based on Current Procedural Terminology (CPT®) guidelines, a review of the Center for Medicare and Medicaid Services (CMS), National Correct Coding Initiative (NCCI) policies and guidelines, specialty society guidelines, and agreed upon industry practices.

Arkansas Blue Cross and Blue Shield uses software products that ensure compliance with standard code edits and rules. These products increase consistency of payment for providers by ensuring correct coding and billing practices and may automatically apply edits using the software’s editing logic. The member is not responsible and must not be balance billed for any procedures for which payment has been denied or reduced by Arkansas Blue Cross and Blue Shield as the result of a coding edit.

 

Policy

I. General Coding

Claims for reimbursement must be reported with valid industry standard CPT, CDT, HCPCS procedure codes and ICD-10 diagnosis codes and appropriate modifiers.

The following payment applies to the category of codes outlined below.

Category II CPT Codes

This code set is a set of supplemental tracking codes that can be used for performance measurement and are intended to facilitate data collection. Using these codes is optional for correct coding and may not be used as a substitute for Category I codes. These services are included in the E&M services billed and are not separately reimbursable. Arkansas BCBS does not require physicians to report the data represented by CPT code. The member is not responsible for charges related to the reporting of the CPT code.

Category III CPT Codes

Category III codes are temporary codes created to identify emerging technology services and procedures. Unlike unlisted or deleted codes, the Category III codes allow data collection for specific emerging technology services. If a Category III code is available, providers must use that code instead of an unlisted or deleted Category I code. The services or procedures represented by Category III codes may not have FDA approval, may not be performed by many health care professionals across the country, and the service or procedure may not have proven clinical efficacy. Claims filed for services using Category III codes will be denied unless the code is addressed as a covered service in an Arkansas Blue Cross and Blue Shield Medical Coverage Policy.

HCPCS "C" Codes

HCPCS "C" codes are temporary codes established by CMS for use under the Hospital Outpatient Prospective Payment System (OPPS). Claims filed for services using HCPCS C codes will be denied unless the code is required to report a covered service in an Arkansas Blue Cross and Blue Shield Medical Coverage Policy.

HCPCS "G" Codes

In general, HCPCS “G” codes are temporary national codes assigned by CMS to identify professional healthcare procedures and services that may not have assigned CPT codes or are under review before being included in the CPT coding system. In general, ABCBS considers G codes as a fragmentation of any other service provided and are generally not reimbursable. Arkansas Blue Cross and Blue Shield would expect that the CPT code that best describes the service(s) would be billed. Some exceptions may apply when there is not a specific equivalent CPT code that exists.

HCPCS "H" Codes

The HCPCS "H" codes are used by those state Medicaid agencies that are mandated by state laws to establish separate codes for identifying mental health services that include alcohol and drug treatment services. Claims filed for services using HCPCS H Codes will be denied. Arkansas Blue Cross and Blue Shield would expect that the CPT code that best describes the service(s) would be billed. Some exceptions may apply when there is not a specific equivalent CPT code that exists.

HCPCS "T" Codes

HCPCS "T" codes are designed exclusively for use by Medicaid state agencies to establish codes for items for which there are no permanent national codes but for which codes are necessary to administer the Medicaid program. Claims filed for services using HCPCS “T” Codes will be denied. Arkansas Blue Cross and Blue Shield would expect that the CPT code that best describes the service(s) would be billed.

Revenue Codes

Revenue codes are four-digit numeric codes used by institutional providers. HCPCS or CPT codes may be required in addition to specific revenue codes, to describe the services rendered.

  • Outpatient institutional claims containing revenue codes 0905, 0906, 0912, 0913 and 0915 will require CPT/HCPCS codes in conjunction with these revenue codes. When submitting outpatient claims with these revenue codes (both electronic and paper), facilities must also use the appropriate corresponding CPT codes as follows:
    • Revenue Code 0905 (Intensive outpatient services - psychiatric) and 906 (Intensive outpatient services-Chemical Dependency) claim must include HCPCS S9480
    • Revenue Code 0912 (Partial hospitalization-less intensive) and 0913 (Partial hospitalization-intensive) claim must include HCPCS S0201
    • Revenue Code 0915 (Group Therapy) claim must include one of the following CPT/HCPCS 90801-90880, 90901, 96101-96120, G0176, G0177, G0396, G0397, G0410, G0411

If billed without the appropriate corresponding CPT/HCPCS code, the claim will reject.

Unlisted or Miscellaneous Codes

Unlisted or miscellaneous codes should only be used when an established code does not exist to describe the diagnosis, service, procedure, or item rendered.

Reimbursement is based on review of the unlisted or miscellaneous codes on an individual claim basis. Claims submitted with unlisted or miscellaneous codes must contain the applicable information and/or documentation below for consideration during review:

  • A written description, office notes, or operative report describing the procedure or service performed
  • An invoice with written description of items and supplies
  • The corresponding National Drug Code number for an unlisted drug code

If the description of the service provided is not present on the claim form and/or electronic record, the information will be requested through a Medical Record Request.

II. Code Editing Software

The Health Plan uses software products that ensure compliance with standard code edits and rules. These products increase consistency of payment for providers by ensuring correct coding and billing practices and may automatically apply edits using the software’s editing logic.

The automated editing includes but is not limited to, code editing software, CMS National Correct Coding Initiative (NCCI) edits and plan specific policy edits. Code editing software is updated regularly to conform to changes in coding standards, CMS published updates and plan specific policy.

The following code edits apply:

  • PTP (Procedure to Procedure)
    • These edits prevent inappropriate payment of services that should not be reported together. Each edit has a Column One and Column Two HCPCS/CPT code. If a provider reports the two codes of an edit pair for the same member on the same date of service, the Column One code is eligible for payment, but the Column Two code is denied. In mutually exclusive relationships, the higher valued code will be denied. If a clinically appropriate NCCI PTP-associated modifier is allowed as indicated on the PTP file and reported, both services may be allowed.
  • MUE (Medically Unlikely Edits)
    • The National Correct Coding Initiative (NCCI) includes a set of edits known as Medically Unlikely Edits (MUE’s). An MUE represents a maximum number of units-of-service that would be expected to be included in any specific CPT or HCPCS code, and therefore could be medically necessary. If more services are submitted than allowed for one date of service for a specific CPT or HCPCS code, the units exceeding the MUE limit will be denied.
  • Add-On Codes
    • Add-on codes describe procedures or services that are always provided “in addition to” other, related services or procedures. Add-on codes cannot stand alone as separately reportable services. Any add on code submitted without an appropriate primary code will be denied.
  • Deleted Codes
    • Claim lines containing deleted procedure codes when submitted with a date of service after the deletion date of the procedure code will be denied.
  • Gender and Age Specific Codes
    • Gender and age specific editing is utilized to identify incorrect coding or fraud. Claim lines containing procedure codes that are inconsistent with the member’s gender or age as indicated in the code descriptor may be denied. If inappropriately applied, claims may be considered on re-review.
  • Procedure Code Unbundling/Rebundling
    • Procedure code unbundling is the submission of multiple procedure codes for a group of specific procedures that are components of a single comprehensive code. Procedure unbundling may occur in one of two ways:
      • A professional claim could be submitted that has procedure codes for both the individual components and the comprehensive procedure. Arkansas Blue Cross and Blue Shield would rebundle the individual component codes into the comprehensive procedure.
      • Procedure unbundling could also occur when a professional claim is submitted with only the individual components of the comprehensive code. In this situation, the system will recognize the relationship between the comprehensive code and its individual components. Then, it will automatically add the comprehensive code to the claim and rebundle the individual components into that comprehensive code.
  • Mutually Exclusive Procedures
    • Mutually exclusive procedures exist when a claim is submitted for two or more procedures that are not usually performed on the same patient on the same date of service. In mutually exclusive relationships, the most clinically intense code is denied. Clinical intensity is generally based on the total RVU for the procedures submitted. This edit would result in the line-item denial of the least clinically intense code as provider liability.
  • Incidental Procedures
    • Incidental is defined as a procedure carried out at the same time as a primary procedure but is clinically integral to the performance of the primary procedure, and therefore, should not be separately reimbursed. This edit would result in the line item denial of the incidental code as provider liability.
  • Medical and Surgical Supplies
    • Medical and surgical supplies during an outpatient or physician office visit are included as incidental to the E/M service or procedure performed and will not be separately reimbursed.
  • National Drug Code (NDC) Numbers
    • A valid 11-digit NDC number, NDC unit of measurement, and NDC units dispensed is required on professional (837P) and outpatient institutional (837I) electronic claim transactions for reimbursement of physician-administered drugs. The NDC must match the valid HCPCS code submitted for the medical drug.
    • NDC's must be reported using the (5-4-2 format). If a drug’s NDC does not follow this format, then a zero must be inserted at the beginning of the appropriate section of the number, to create the 5-4-2 format.
    • The NDC should not be added to the line item on the claim for an office visit, administration code, lab or x-ray code.
    • The appropriate HCPCS/NDC combination should be billed when available instead of a not otherwise specified code (i.e., J3490, J3590, J7999, J8499, J9999, A4641, A9699, and C9399).
      • Effective February 2025 If the claim does not include the appropriate HCPCS/NDC combination, the entire claim will reject.
    • Expired NDC or expired HCPCS code should not be billed. This will result in the rejection of the claim.
    • NDC, procedure code and effective date combination will be validated. If the combination is not valid, the claim will reject.
    • If the line on the claim containing the NDC cannot be validated, the entire claim will reject.
  • Modifier Procedure Validation
    • Modifiers are subject to compatibility edits with the procedure to which they are appended. For example, an Evaluation and Management (E/M) service appended with a -59 modifier will be denied.
  • Ancillary Services
    • Certain procedures are deemed to be non-covered based on medical coverage policy or a specific benefit exclusion in the member benefit certificate of coverage. When procedures related to those non-covered services are submitted, reimbursement for these ancillary services will be denied. If no other payable major surgical service was performed on the same date of service, the ancillary services (i.e., anesthesia, assistant surgeon, pre-op testing, pathology or radiology) will also be denied.
