Requirements for Determination to be Disabled by Physician Certification

What are the Administrative Discharge Requirements for a Person Determined to be Disabled by Physician Certification?

You can submit certification from a physician that you are totally and permanently disabled. Your physician must certify that you are unable to engage in any substantial gainful activity by reason of a medically determinable physical or mental impairment that can be expected to result in death or has lasted for a continuous period of no less than 60 months or can be expected to last for a continuous period of no less than 60 months. Only a doctor of medicine (M.D.) or osteopathy (D.O.) licensed to practice in the United States may certify your total and permanent disability.
