At IHX Inner Circle, our invite-only roundtable that brings together leading voices from India’s hospital ecosystem, we caught up with Dr.Hardik Ajmera, Medical Director at Saifee Hospital, to understand how technology is influencing both patient experience and hospital operations.

India’s #1 Preventable Killer is hiding in plain sight

The numbers are huge. But in our healthcare data, this crisis is almost invisible. Here is why that gap exists — and what we can do about it.

Every day, nearly 3,700 Indians die from tobacco-related illness. Yet in claims data, this crisis is almost invisible.

03 — The Difference

India ≠ The World:
Oral Cancer Outranks Lung Cancer

India is the only major country where oral cancer, not lung cancer, is the top tobacco-linked cancer. The main reason is smokeless tobacco — Gutka, Khaini, and Paan masala — which shapes India’s unique habit. This changes how each case should be coded in claims.

ICD Code Condition Tobacco Attribution Avg. Stay*
C06 Oral Cancer Highest Stay 90% 6 days
C10 Oropharynx Cancer 85% 5 days
J44 COPD / Bidi-Related 82% 3 days
C34 Lung Cancer 75% 4 days
J65 TB + Tobacco Comorbidity India-Unique 60% 2 days
Overall Across all tobacco-linked codes ~75–80% ~2.5–3 days*

04 — The Paradox

India’s Biggest Killer Barely Shows Up in Claims Data

<1%*
of total claim amounts carry any tobacco-linked ICD code
2.5–3*
average days of inpatient stay for tobacco-coded claims
↓
Shorter stays mean smaller claim values, so tobacco stays hidden in overall reports
With 268 million tobacco users, you would expect tobacco to fill our healthcare claims. Instead, it barely shows up. The disease appears in records, but the tobacco link is missing from the paperwork. This is not a one-off error — it is a gap built into how we document.

*Analysis based on anonymized and aggregated data

05 — Root Causes

Why the Data Gap Exists:
Three Interconnected Failures

01
Not Declared When Buying a Policy
40 to 60% of tobacco users do not mention their habit when they buy insurance.
02
Disease Appears Much Later
Tobacco-related diseases often show up 8 to 10 years after use begins, long after the policy is issued.
03
F17.x Code Rarely Recorded
The code for tobacco use is often left out, especially in Tier 2 and Tier 3 hospitals.
Key Code to Know
F17.x — Nicotine Dependence (ICD-10)
When F17.x is recorded at discharge, it creates a clear, traceable link between a patient’s tobacco use and their illness. The problem? It is rarely added, especially in Tier 2 and Tier 3 hospitals. So the tobacco-disease link stays hidden from insurers, risk models, and public health systems.

06 — The Actions

What Providers & Payers Can Do

🏥 Providers & Hospitals
  • Record F17.x at every discharge. Make tobacco history a standard field, not an optional note.
  • Screen for oral cancer in Tier 2 and Tier 3 cities, where smokeless tobacco use is highest and cancer is found late.
  • Offer spirometry (a simple lung test) for patients 40+. It can catch COPD early, before it becomes a costly claim.
🛡️ Payers & Insurers
  • Ask about tobacco use clearly at the start. Go beyond a simple checkbox to a question that gives real clinical value.
  • Match ICD codes with F17 history. Flag claims for C06, J44, C34, and J65 where tobacco use was not declared.
  • Use a longer 8 to 10 year lookback. Tobacco disease takes years to appear, so underwriting must look back further.

07 — Tech Layer

What Health-Tech & AI Can Do

01
Scan Claim Notes for Hidden Tobacco Clues
AI that reads text (natural language processing) can go through clinical notes, discharge summaries, and referral letters to find tobacco mentions that never made it into the coded fields. This adds a second layer of checking that manual review would miss.
02
Flag C06 / J44 / C34 Claims with No F17 History
When a tobacco-linked diagnosis appears but there is no tobacco-use code, that is a signal, not a coincidence. Auto-flagging turns a missing record into an alert worth reviewing.
03
Connect Hospital Coding to Insurer Risk Models
Live data links between hospital discharge coding and insurer risk systems allow earlier action. This moves the industry from reacting to claims to managing health ahead of time.
The goal is not surveillance. It is early detection and timely care. Better data leads to better outcomes, at lower cost, for everyone in the system.

Better Data.
Better Outcomes.
For Everyone.

No single group can solve India’s tobacco crisis alone. It needs providers, payers, and health-tech moving in the same direction — with better data as the base.
