Dear Saswata Banerjee, I have read about this continued treatment some time ago, and I am confident about it. I researched and found the following information:
"
Medical Treatment for Insured Persons Medical treatment for Insured Persons who are no longer covered by the scheme. During the treatment period, they are entitled to receive continued treatment once it has started, until the sickness ends or for long-term ailments as long as the Insured Person requires active treatment."
This information is sourced from the web page of ESIC, Coimbatore. I have attached a PDF copy for reference.
I must correct a mistake I made by stating that this also applies to dependents. I apologize for providing incorrect information.
Please be aware that this type of medical benefit is extended to Insured Persons until the end of their illness.
With Warm Regards,
S. Sethupathy
