Tina Ambani has launched an initiative called "Mission 1,200 Children Per Annum" at Kokilaben Dhirubhai Ambani Hospital in Mumbai to provide free or subsidized treatment for congenital heart disease to children from economically disadvantaged families in Maharashtra. The initiative works with the state government's Rashtriya Bal Swasthya Karyakram and has already treated children from 23 districts across Maharashtra. The hospital has set up a special ward and guarantees treatment without delays, and also provides post-operative care before discharging patients who are then given a happiness bonus through Make-A-Wish Foundation.
