Remark code M15 indicates that services or tests billed separately have been combined because they are deemed to be parts of a single comprehensive procedure. As a result, separate reimbursement for these components is not permitted.
Common causes of code M15 are:
1. Incorrect use of procedure codes: Providers may have inadvertently used multiple procedure codes for tests or services that are typically bundled under a single comprehensive code.
2. Lack of understanding of bundling rules: Providers might not be fully aware of the Current Procedural Terminology (CPT) or Healthcare Common Procedure Coding System (HCPCS) guidelines that dictate which services are considered components of a larger, single procedure.
3. Outdated coding practices: The healthcare provider may be using an outdated set of codes, not realizing that coding guidelines have changed to bundle certain services together.
4. Software or human error: Automated billing systems or coding personnel might incorrectly assign separate codes to services that should be bundled, leading to this denial.
5. Misinterpretation of payer-specific rules: Different insurance payers may have unique bundling policies that differ from standard coding guidelines, and providers may not have billed in accordance with these payer-specific rules.
6. Unbundling: This occurs when providers intentionally or unintentionally separate a procedure into parts to increase reimbursement, which is against coding guidelines and payer policies.
7. Modifier misuse: Providers may fail to use the appropriate modifiers or may use them incorrectly, which can result in services that should be bundled being billed separately.
Understanding and addressing these common causes can help healthcare providers improve their billing practices and reduce the likelihood of receiving code M15 denials.
Ways to mitigate code M15 include implementing a robust charge capture system that identifies and flags services that are typically bundled according to the Correct Coding Initiative (CCI) edits. Training billing staff on the nuances of bundled procedures can also help prevent this code. Regularly reviewing and updating the charge master to ensure compliance with current bundling regulations is essential. Additionally, utilizing claim scrubbing software that checks for bundling issues before submission can reduce the likelihood of receiving an M15 denial. It's also beneficial to perform periodic audits of billing practices to ensure that services are correctly coded and that any changes in bundling rules are promptly incorporated into the billing process.
The steps to address code M15 involve reviewing the coding of the services or tests billed to ensure they were not incorrectly unbundled. If the services were correctly coded as separate entities, gather documentation that supports the medical necessity and distinctiveness of each service or test. Then, resubmit the claim with a clear explanation or appeal the decision with the payer, providing the supporting documentation to justify the separate billing. If the services were indeed components of the same procedure, adjust the billing to reflect the correct bundled code and resubmit the claim. It may also be beneficial to provide education to the coding staff to prevent similar issues in future billing cycles.
