Do I need to apply for medical again after a passport renewal during?
Medical examinations have 1 year expiry date so irrespective of any circumstances, document altercations and file re-submission, your medical results will be valid if 1 year has not passed. In this case if you have cleared medical test in October 2017 and you are renewing your passport in January 2018 then you dont need to apply for Medical examination again. You are okay till October 2018. Hope this helps.
