Conclusion
You can get different Medicare resources via the Social Security website and Medicare.gov. You can use these resources to check your enrollment status. The method used in checking your status depends on the plan you enroll in. You can visit your local Social Security office or contact social security. In most cases, it takes months to finish one application process. You must ensure that the Medicare information sent to your mail is correct and matches with the details you filled in during enrollment.
