Yes, you can delay Medicare enrollment to continue contributing to a Health Savings Account (HSA) if you are eligible for Medicare but remain on your employer's health insurance plan and continue working past age 65. You can delay both Part A and Part B of Medicare until you or your spouse stop working or lose employer coverage. You won't face a penalty for delaying Medicare if you enroll within eight months of losing coverage or stopping work, whichever happens first. You should also wait to collect Social Security retirement benefits if you delay Medicare enrollment
