The upper middle class increasingly have insurance like people in the US, and the very wealthy pay for treatment directly. Both groups seek care at private hospitals that have equipment and staff that would rival those in wealthy countries - often set up and funded by Indian physicians abroad.
My family have to invested in such hospitals and I have toured them. No doubt they do charitable work on the margins, but they likely can't scale to a pandemic.

"It covers 3 days of hospitalisation and 15 days of post hospitalisation, including diagnostic care and expenses on medicines."
3 days of hospitalization even with the best facilities is probably nowhere near enough for a serious COVID19 case.
Then again, health insurance providers in the US also recently balked quite strongly at the US administration's suggestion that they cover the full cost of COVID19 treatment, including co-pays:

How this all is paid for - and the delicate question about who has the right to the best treatment (those who can pay?) - are big issues that will soon be faced by health services and governments in all societies, whether wealthy or developing.
There are government hospitals and they are average. They are better avoided by people who can afford private clinics.
But for epidemic causing diseases the government is very active and proactive when they understand the protocol. If you are in quarantine, they will give your free medicines for you and the people you contacted, free and hygienic food, will sanitize your house and neighborhoods if needed. If you hospitalized yourself to a private hospital, the cost is yours. But otherwise the government will take care of hospitalization. Their quarantine beds are nothing less than world-class. However, things can be drastically different and painful for your care taker once out of quarantine. ICUs (non-quarantine) in government hospitals have a higher rate of passing on a secondary infection.
Even at the costly private hospitals, cost of healthcare is quite low in India compared to the western countries and quality is similar. But they are not adequate for the pandemic of Covid19 scale
Public healthcare is abysmal unless you are in a tier 1 city or higher. Central government does little and most responsibilities is on the state government so you would see varied healthcare in different states.
I don't see many people using insurance to pay their bills. Most of it is paid by their pockets. It's changing but I don't want a situation where majority of the people have health insurance and companies start abusing the lowest section of the population who wouldn't be able to afford it. It's already happening. If you let clinics know that you are covered by insurance, they will do more quite a lot more tests and make you sit there.
The private hospital sector is better though. But not everyone can afford it.
