1. Dear member, so far as I understand under ESI Act, 1948 there are various benefits and under the situation as mentioned above in case of pregnancy, the insured woman will be entitled for 2 type of benefits i.e. (a) medical benefit i.e. medical treatment/hospitalisation for delivery etc. and (b) Maternity Benefit in the form of cash benefit i.e. in common language we may call as salary of the maternity leave period upto the extent as allowed in said Act (as amended as mention in my earlier remarks above).
2. So far as position regarding medical treatment is concerned, the insured woman will undoubtedly be entitled for medical treatment / hospitalisation etc. And so far as payment of Maternity Benefit is concerned, it will be more better if you may contact the appropriate ESIC Branch Office to which you are attached in order to confirm your eligibility as on 01/10/2017. Regarding eligibility in respect of marginal case as mentioned above, hope you will go through Regulation 4 (proviso) to ESI (General) Regulations, 1950. The insured woman is also required to visit and consult the appropriate ESIS Doctor to confirm and get medical certificate regarding "Expected date of confinement" as required under Rule 56 of ESI (Central) Rules, 1950. These Regulations / Rules can be seen /downloaded from the website of ESIC. With best wishes.
