New in 2023
Here is a list of the most significant changes for 2023:

- A law that took effect in 2022 requires insurance agents, brokers, and other third-party marketing organizations (like the ones that sponsor TV ads) to record all calls with beneficiaries in their entirety, including the enrollment process. They must disclose that their information will go to an agent for future contact, and they may be transferred to an agent who can enroll them in a plan.
- As of January 1, 2023, the Centers for Medicare and Medicaid Services must approve all television ads in advance and review ads already on air to ensure they meet all marketing requirements.
There are more changes coming in the next couple of years, like the $2,000 cap on Part D drug costs. Watch for updates.
