Manda Krishna Madiga played a significant role in advocating for children with cardiac problems in 2004. During that time, there was a girl named Naseem from
Madhira in
Khammam district who needed 1 lakh 40 thousand rupees for a heart operation. Naseem was of Muslim faith. Krishna Madiga sought assistance from then Chief Minister
Y. S. Rajasekhar Reddy, who provided only 25 thousand rupees. When Krishna Madiga requested the remaining amount, YSR declined, urging Naseem to collect the rest independently. When further pressed, YSR expressed concern that granting this request would open the floodgates for similar demands and even made threats against Krishna Madiga if the matter persisted. Subsequently, Krishna Madiga led a rally with children, emphasizing the importance of regular screening tests every six months to prevent treatment delays. He also called for the allocation of funds from the Chief Minister's Relief Fund specifically for this program. Madiga's actions contributed significantly to raising awareness about child heart diseases and the necessity of government involvement. As a result, in August 2004, 24 screening camps were established in the state, identifying 5,500 children with heart diseases. It to led to creation of
Aarogyasri scheme which is the flagship scheme of all health initiatives of the state government to provide quality healthcare to the poor.
Fight for Disabled Rights In 2007, Manda Krishna Madiga started an organization called Vikalangula Hakkula Porata Samiti () to fight for the rights of
disabled people. They held a big event called 'Vikalangula Maha Garjana' at
Nizam College grounds. Krishna Madiga pointed out that disabled people in Andhra Pradesh received only Rs 200 as a monthly pension, while it was Rs 400 in Tamil Nadu and much higher in Pondicherry. To make their demands known, Krishna Madiga and around 2,000 disabled individuals gathered at the
Babu Jagjivan Ram statue in Basheerbagh for a protest. In 2012, VHPS organized another protest called 'Vikalangula Poru Yatra' in
Visakhapatnam. Manda Krishna Madiga participated in this protest and criticized the state government for not addressing the challenges faced by disabled people. He highlighted that there were 6 crore disabled people in the country, but not enough was being done to help them. Manda Krishna Madiga had several demands, including reserving 5% of local bodies seats for disabled individuals, ensuring strict implementation of a 3% reservation for them in employment, increasing the pension for disabled individuals from Rs. 500 to Rs. 1,500, providing them with schemes and subsidies similar to those for Scheduled Castes (SCs) and Scheduled Tribes (STs), creating a special plan for disabled individuals, offering free housing, electricity, and transportation, giving priority to disabled individuals in land distribution, and increasing the special allowance for disabled employees from Rs. 900 to Rs. 1,500, among other things. == Political career ==
