The five states present something that aggregate health statistics have consistently obscured.
Synopsis: Southern India tops private hospitalisation costs, with Tamil Nadu, Telangana, Kerala, Karnataka, and Andhra Pradesh leading. Cancer in Tamil Nadu, heart disease in Telangana, kidney failure in Kerala, and cardiac care in Andhra Pradesh are the most expensive. Public hospitals remain far cheaper, but trust in specialist private care drives families into high bills despite insurance support.
Imagine two patients. Both get diagnosed with cancer. One lives in Odisha. Other lives in Tamil Nadu.
The Odisha patient pays Rs 28,864 for a private hospital stay. The Tamil Nadu patient pays Rs 1,35,368. Same disease. Same private hospital setting. Nearly five times the bill.
This is not an anomaly. It is the pattern that runs through the NSS 80th Round, released by the Ministry of Statistics and Programme Implementation on 20 April 2026, covering 1,39,732 households surveyed through 2025. The most comprehensive health expenditure study in India in nearly a decade, it documents what falling ill actually costs, by state, by disease, by hospital type.
What it reveals about southern India is striking. The five states, Tamil Nadu, Telangana, Kerala, Karnataka, and Andhra Pradesh, occupy five of the top six positions for overall private hospitalisation costs nationally. They also carry a disproportionate share of India’s non-communicable disease burden, accounting for 58.8 percent of all diabetes deaths despite having only 33.3 percent of medically certified deaths.
The diseases that cost the most to treat are the diseases the south has the most of.
Cancer is the most expensive disease to treat in India. In Tamil Nadu, it costs more than anywhere else.
A private hospital cancer admission in Tamil Nadu runs to Rs 1,35,368, 72 above the national average of Rs 78,657. Delhi at Rs 1,33,538 comes close. Every other state falls well short.
Tamil Nadu has also recorded 21,986 diabetes deaths in 2023, the highest absolute number in India. Diabetes and cancer are not unrelated. A state living with 14.4 percent tested diabetes prevalence generates a large and growing cancer caseload, year after year.
The infrastructure that treats those cases is formidable. Chennai’s tertiary oncology centres handle referrals from across South Asia. The charitable and trust-run hospital sector, which sounds affordable, records an average cost of Rs 1.24 lakh per hospitalisation. That is the highest for any hospital category in any state in the country, and higher than private hospital costs in most of India.
That number raises an uncomfortable question. What does charitable mean when the bill exceeds private rates elsewhere? The answer is case complexity. Patients arrive at these institutions after smaller hospitals have already decided they cannot help. The bill reflects what it takes to treat them.
The overall picture in Tamil Nadu is one of consistent, top-end pricing. Cardiovascular disease costs Rs 84,475. Musculo-skeletal conditions cost Rs 64,563. Public hospitals charge Rs 1,364 per admission, making Tamil Nadu’s public-private gap the most extreme in the country. Private care costs nearly 60 times what government care costs.

Cardiovascular disease kills more Indians than any other condition. In Telangana, it also costs more to treat than anywhere else.
A private hospital cardiac admission in Telangana costs Rs 95,095, 70 percent above the national average of Rs 55,870. In every other state, cancer costs more than heart disease to treat privately. In Telangana alone, the order flips. Heart disease at Rs 95,095 edges out cancer at Rs 94,047. It is the only state in the country where this happens.
The near-tie between the two most expensive conditions is itself a signal. Both are consuming extraordinary resources simultaneously.
What makes this harder to explain away is the diabetes connection. Diabetes is the condition most likely to put a patient in a cardiac ward. Telangana’s ICMR-INDIAB tested diabetes prevalence stands at 9.9 percent. Yet the state recorded only 368 diabetes deaths in 2023, a rate of 0.4 percent of medically certified deaths.
Compare that to Kerala, with similar population size and higher prevalence, which recorded 6,624 diabetes deaths at 19.1 percent of certified deaths. The gap is not better health outcomes in Telangana. It is what gets written on the death certificate. The death says heart failure. The diabetes that caused it goes unrecorded.
Patients arrive at Telangana’s private cardiac wards having managed, or mismanaged, undiagnosed diabetes for years. They arrive sicker. The bill reflects that.
And it is not just the heart. Telangana appears in the top three most expensive states for ten of the survey’s seventeen disease categories. Infections cost Rs 24,496, 56 percent above national. Injuries cost Rs 77,518, 54 percent above. Eye conditions cost Rs 28,897, 77 percent above. The consistency across unrelated conditions points to something structural in how the state’s private hospitals price their services.
Rural patients find no refuge. A hospital stay in rural Telangana costs Rs 48,023 on average, against a national rural average of Rs 32,884. The premium is not a Hyderabad phenomenon. It runs across the state.
Overall, Telangana records the highest hospitalisation cost of any major state in India at Rs 52,743, 39 percent above the national average of Rs 37,858.
Kerala counts its dead more carefully than almost any other state. When a patient dies with diabetes contributing to the outcome, the death certificate says so. That precision produces a number that looks alarming: 19.1 percent of all medically certified deaths in the state list diabetes as a cause.
It is not alarming because Kerala has worse outcomes. It is alarming because it is probably the most accurate picture of how many Indians actually die with diabetes, and most other states are not counting the same way.
What Kerala is living with is a 25.5 percent tested diabetes prevalence, one in four residents. Another 18.3 percent hover in prediabetes territory. The pipeline of future patients is large, documented, and moving steadily toward complications.
Diabetes destroys kidneys. Kerala’s expenditure data shows the consequence with clinical precision. Kidney failure is the single most expensive condition in Kerala’s private hospitals at Rs 84,436 per hospitalisation. The connection between the state’s diabetes burden and its kidney failure costs is not an inference. It is the biological pathway made financial.
The overall private hospitalisation cost in Kerala runs to Rs 56,150. Maternal care adds its own pressure, a private hospital delivery costs Rs 49,029, nearly ten times what a public hospital charges. Most Kerala families who can afford the alternative choose private. The bill follows that choice.
Public hospitals in Kerala cost around Rs 9,433 per hospitalisation. The gap between public and private is real but not as extreme as in Tamil Nadu. What makes Kerala’s situation different is the nature of what lies ahead.
With one in four residents already diabetic, the wave of kidney complications, cardiac events, and neurological damage that follows uncontrolled diabetes will not diminish. It will grow. And it will arrive at private hospitals that already charge among the highest rates in the country.

Karnataka’s overall hospitalisation figure of Rs 40,599 sits in the middle of the southern range. That number flatters the state slightly.
Charitable hospitals in Karnataka record an average cost of Rs 68,009 per hospitalisation, second highest in the country after Tamil Nadu. Bengaluru has built a concentration of specialist tertiary facilities that draw patients from across the region, and those facilities price accordingly.
Cancer treatment costs Rs 1,14,334, third highest nationally. Genito-urinary conditions cost Rs 63,157. For patients who need specialist care, the Bengaluru premium is real and substantial.
Karnataka carries a 10.6 percent tested diabetes prevalence, above the national average and climbing. As that cohort ages into the complications that diabetes produces, they will encounter a specialist private sector that already charges near the top of the national scale.
Andhra Pradesh is the most affordable of the five southern states for overall hospitalisation at Rs 42,517. The rural-urban gap is the narrowest of any southern state, rural costs at Rs 39,704, urban at Rs 38,244. That evenness keeps the average contained.
Within that contained figure, one condition breaks out. Cardiovascular disease costs Rs 84,387 in Andhra Pradesh’s private hospitals, above cancer, above kidney failure, above everything else. It is the most expensive single condition in the state, and it sits 51 percent above the national cardiovascular average.
Andhra Pradesh’s ICMR-INDIAB tested diabetes prevalence stands at 9.5 percent. Notably, 3.4 percent of women and 3.5 percent of men self-report diabetes in NFHS-5, among the higher self-reporting rates in the country, suggesting better awareness than most states. That awareness has not translated into lower cardiovascular costs.
The cardiac wards fill anyway. Diabetes that is known but inadequately controlled still damages arteries. The bill that follows does not distinguish between managed and unmanaged disease.

Read together, the five states present something that aggregate health statistics have consistently obscured.
Southern India built the best healthcare infrastructure in the country. It also accumulated the diseases that infrastructure now treats, driven by longer lives, higher incomes, changing diets, and better diagnosis that finds conditions which elsewhere go undetected. The diseases of development, arriving in the states that developed first.
Cancer in Tamil Nadu: Rs 1,35,368. Heart disease in Telangana: Rs 95,095. Kidney failure in Kerala: Rs 84,436. Heart disease in Andhra Pradesh: Rs 84,387. Cancer in Karnataka: Rs 1,14,334.
These are not costs in isolation. They are the costs of treating diseases that built quietly over years, in healthcare markets that have priced themselves for the complexity of what they manage.
The public sector offers relief. Tamil Nadu’s government hospitals charge Rs 1,364 per admission. Telangana’s charge Rs 5,856. Kerala’s charge around Rs 9,433. The national median government hospitalisation costs Rs 1,100. For patients who use public facilities, the financial catastrophe does not arrive in the same form.
But in the south, where trust in specialist private care runs high and the conditions being treated are complex enough that patients believe they need it, many choose not to take the public option. The bill that follows is the one the survey records.
Insurance covers some of it. The NSS data documents that even after reimbursement, out-of-pocket medical expenditure in Telangana’s private hospitals runs to Rs 64,228 per hospitalisation. Tamil Nadu’s stands at Rs 74,168. Insurance has not closed the gap. In states where private hospitals charge the most, it has largely bankrolled the premium rather than contained it.
The NSS 80th Round does not measure outcomes. It does not record whether the expensive cancer treatment in Tamil Nadu produces better survival rates than cheaper care elsewhere. It does not know whether Telangana’s cardiac patients leave hospital healthier than those treated in Rajasthan for a third of the cost.
What it knows is the bill. And in southern India, that bill is higher than anywhere else in the country, for the diseases the south has carried longest, and will carry furthest into the future.
