What can Mr. Rockwell do because his employer's drug benefits are no longer creditable?

The correct course of action for Mr. Rockwell is to use a Special Enrollment Period (SEP) to enroll in Medicare due to the loss of creditable drug coverage. Creditable coverage means that the plan's drug benefits are at least as good as the standard Medicare prescription drug coverage. When Mr. Rockwell's employer's drug benefits cease to be creditable, he qualifies for a SEP.

This allows him the opportunity to enroll in Medicare without facing penalties or having to wait for the Annual Election Period. The Special Enrollment Period is specifically designed for situations like this, where an individual experiences a qualifying event, allowing them to sign up for Medicare coverage outside the typical enrollment windows. By utilizing this SEP, Mr. Rockwell can ensure that he maintains necessary healthcare coverage in a timely manner.
