Yes, day care procedures are often covered under health insurance as they provide financial relief in case of emergency.
These include treatments like cataract surgeries, chemotherapy, radiation therapy, dialysis, hymenectomy, and arthroscopic knee aspirations among many other procedures.
Given the fact that many such treatments can be done under 24-hours and are not only needed by many patients but also include high healthcare expenditure, the IRDAI (Insurance Regulatory & Development Authority of India) introduced the same in health insurance policies.
Thank God for that! Thereby, daycare procedures refer to such treatments that require hospitalization of less than 24-hours due to medical advancements.
A good example of the same would be, when someone has to be admitted into the hospital for a cataract surgery, post which he/she will also receive care at the hospital and then be discharged within the same day itself.
