I hve my mother in law visiting us and she is 67 yrs. We purchased medical insurance from India (Oriental Insurance) for which the prm was around INR 10163/- for 106 days.
The coverage is good as it also has lost and delayed baggage allowances as well as provisions for trip disruptions.
She travelled from Mumbai and is based out of Mumbai and we had an agent doing the paper work for us who is basically a family friend.
