If you missed your IEP seven months window, you could still enroll in Original Medicare (Part A and Part B) during the General Enrollment Period. However if you enroll during the annual General Enrollment Period, your Medicare Part A and B will not start until July first of that year. Therefore, there would be a big possibility that you could have a gap in coverage. If you didn’t maintain creditable coverage, you could be subject to Part B late enrollment penalty that you will have to endure.
