When billing with unlisted or miscellaneous codes on claims submitted to Blue Cross and Blue Shield of Texas (BCBSTX), you can avoid additional documentation requests for unlisted or miscellaneous codes by describing the specific drug, service, supply or procedure provided. This will help avoid processing delays or denials, and unnecessary requests for medical records and/or supporting documentation.
What are unlisted or miscellaneous codes?
These are codes labeled as Non-Specified, Not Listed, Not Elsewhere Specified (NEC), Not Otherwise Classified (NOC), Not Otherwise Specified (NOS), Unclassified, Unlisted, or Unspecified.
Pre-Service Review
Some unlisted or miscellaneous codes could require prior authorization to determine coverage and benefits. Be sure to check eligibility and benefits via Availity® Essentials or your preferred electronic vendor to confirm prior authorization requirements and vendors, if applicable. If prior authorization is required, services performed without prior authorization or that do not meet medical necessity criteria may be denied for payment and the rendering provider may not seek reimbursement from the member.
If you submit a prior authorization or predetermination request that includes an unlisted or miscellaneous code, be sure to include a detailed description of the service. along with any documentation to support your request. This step helps avoid the need for post-service medical necessity review.
Refer to our Utilization Management section for more information, such as how to submit electronic requests for prior authorization and predetermination.
Claim Filing
Claims submitted with an unlisted or miscellaneous code without a description are typically denied for lack of supporting documentation. Get your claims processed faster by submitting a pre-service request as noted above and/or including a description of the specific drug, service, supply or procedure on your claim.
When using unlisted or miscellaneous codes on claims for all BCBSTX members:
- Use the most specific unlisted code that’s available if a code doesn’t exist that accurately describes the drug, service, supply or procedure.
- Describe the service and include documentation when submitting claims with codes that are identified as “unlisted” or “miscellaneous.”
