Who can impose a penalty if you fail to notify the excess carrier of a claim?

The correct answer is that the excess carrier can impose a penalty if there is a failure to notify them of a claim. In workers' compensation cases, excess insurance provides coverage above a certain limit after the primary insurance has been exhausted. The excess carrier has a vested interest in being promptly notified of claims to assess any potential liability and manage their risks. If the primary insurer, or any designated party, fails to inform the excess carrier about a claim in a timely manner, the excess carrier may face unforeseen financial exposure and, therefore, has the right to impose penalties for such oversight.

This context highlights the importance of communication and compliance within the workers' compensation framework, ensuring that all parties involved understand their roles and responsibilities concerning reporting claims. The other choices do not possess the authority to impose penalties related to notification of the excess carrier, as they do not have the same vested interest in the claims process.
