What is the minimum notice period an insurer must provide to policyholders regarding any modifications to Medicare supplement insurance policies?

The correct choice is 30 days because under regulations governing Medicare supplement insurance policies, insurers are required to inform policyholders of any changes or modifications to their policy terms at least 30 days in advance. This notice period ensures that policyholders have sufficient time to understand the changes being made to their coverage, allowing them to make informed decisions about their health insurance options. The 30-day notice aligns with industry standards for providing transparency and maintaining trust in the insurer-policyholder relationship.

While there are other notice periods defined for different circumstances in insurance regulations, for modifications to Medicare supplement policies specifically, the 30-day notice is the legal requirement, ensuring that beneficiaries are well-informed and have adequate time to respond or seek alternatives if needed.
