Sir(s),
I hope you must have seen the provisions of Rule 50 of ESI (Central) Rules, 1952 and the proviso to said Rule lays down that 'the wage limit for coverage of an employee who is a person with disability under the Persons with Disabilities (Equal Opportunities Protection of Rights and Full Participation) Act, 1955 (1 of 1966), and under the National Trust for Welfare of Persons with Autism, Cerebral Palsy, Mental Retardation, and Multiple Disabilities Act, 1999 (44 of 1999) respectively shall be....."In view of these provisions, I think, ESIC will not be in a position to help you regarding continuation of your coverage under said Act if your wages are at present more than coverage limit of Rs.15000/- per month.
I think, you will be required to approach the relevant authorities of your area created under any of above 2 enactments(depending on your disability) and obtain necessary certificate of your disability and thereafter request your present employer to continue your coverage under ESI Act till prescribed wage ceiling of Rs.25000/- per month as presently prescribed for persons with disability.
In case of your having any doubt, I will suggest you to take up your case to the Regional Director (Benefit Branch), ESIC of your area in writting with all details and request accordingly.
As per provisions of Rule 51-A of said rules, the employers' share of contribution in such cases is to be reimbursed to the ESIC by the Central Government. Therefore, in my opinion, obtaining of certificate of disability under any of above 2 enactments (as may be relevant to you) is essential.
