Remark code N356 is an alert that a service isn't covered if done with or after a non-covered procedure.
Remark code N356 is an indication that the service billed is not covered by the payer because it was performed in conjunction with, or subsequent to, a service that is not covered under the patient's health plan.
Common causes of code N356 are billing for a service that is typically not covered by the payer when it is performed in conjunction with, or immediately after, another service that is also not covered. This can occur when the initial non-covered service renders any subsequent services non-reimbursable under the patient's current insurance policy terms. Additionally, this code may be triggered if the sequencing of billed services implies that a non-covered procedure necessitated the follow-up service, thereby making the latter ineligible for coverage.
Ways to mitigate code N356 include implementing a robust pre-authorization process to ensure that all services, especially those that are often bundled, are covered before they are performed. Regularly updating and training staff on the latest coverage guidelines from payers can also help avoid performing non-covered services alongside covered ones. Utilizing advanced coding software that flags potential conflicts between services can prevent claims from being submitted with this issue. Additionally, conducting periodic audits of billing and coding practices to identify and rectify patterns that may lead to this code being applied can be beneficial. Establishing clear communication channels with payers to discuss and clarify coverage details before performing services that are commonly bundled can also reduce the incidence of this code.
The steps to address code N356 involve a detailed review of the patient's medical records and the services billed. First, identify the non-covered service that triggered the N356 code. Once identified, assess whether the non-covered service and the service associated with N356 were indeed related or if they were mistakenly linked. If they were mistakenly linked, prepare and submit a detailed appeal to the payer, including documentation that clearly separates the services in question, demonstrating that the service associated with N356 was medically necessary and independent of the non-covered service. If the services were correctly linked, evaluate if there are alternative billing options or modifiers that could be applied to the service associated with N356 to facilitate coverage. Additionally, communicate with the patient regarding the denial and discuss potential financial responsibility and options, ensuring transparency and exploring all avenues for appeal or alternative billing solutions.
