Insurance Fraud in India: Inside the BCG “Rebuilding Trust” Report

Insurance Fraud in India: The ₹10,000-Crore Problem Hiding in Plain Sight

India’s insurance story has two faces.

On one side, the country is finally beginning to look like a serious health-insured nation. Government schemes, employer covers and retail policies together have brought some form of health protection to tens of crores of people. Ayushman Bharat alone now touches a large share of the population, and digital rails such as ABHA IDs and the Ayushman Bharat Digital Mission stack are spreading fast.

On the other side, a quiet leakage is eating into this progress.

According to Medi Assist and Boston Consulting Group’s 2025 Raksha Summit report, “Rebuilding Trust: Combating Fraud, Waste, and Abuse in India’s Health Insurance Ecosystem”, thousands of crores are being drained every year through fraud, waste and abuse (FWA) in health insurance. The numbers are large enough to change how insurers price risk, how hospitals behave, and how much honest customers end up paying.

India’s health insurance boom and the cost problem nobody sees

Before we talk about fraud, it’s important to understand the backdrop.

Over the last few years:

• Health insurance premiums in India have grown strongly.
• The Government’s vision of “Insurance for All by 2047” has pushed schemes like Ayushman Bharat deeper into the system.
• Digital health identifiers and platforms have started linking patients, hospitals, insurers and TPAs on common rails.

At the same time, medical costs have been rising much faster than general inflation. Healthcare inflation has been hovering in low double digits, while overall CPI inflation has stayed much lower. As a result, the average health claim size has climbed sharply, and insurers are under pressure even before fraud is taken into account.

When you add fraud, waste and abuse on top of already expensive healthcare, you get a structural problem: premiums creep up, benefits get trimmed, and affordability becomes the casualty.

Fraud, waste and abuse:

The Raksha Summit report clearly distinguishes three behaviours that often get lumped together.

Fraud
Deliberate cheating for financial gain.
Examples include a hospital claiming for a surgery that was never actually done, or a policyholder submitting fabricated bills for a “hospital stay” that did not happen.

Waste
Avoidable cost and inefficiency, even if there is no criminal intent.
This could be keeping patients admitted longer than medically necessary, or using expensive consumables where cheaper, clinically equivalent options would work.

Abuse
Practices that technically follow the rules, but clearly misuse the spirit of those rules.
Typical patterns include unbundling a standard procedure into multiple billable components, or stacking investigations of doubtful clinical value to push up the bill.

From an insurer’s balance sheet point of view, all three finally show up as FWA. They are difficult to separate at scale, but their combined impact is measurable – and that is where the BCG report is blunt.

The headline number: up to 8 to 10% of payouts lost

The most widely cited finding from the report is simple and stark:

Up to 8–10% of total health insurance claim payouts in India are estimated to leak out due to FWA, which translates into roughly ₹8,000–10,000 crore every year.

In other words, for every ₹100 that insurers pay out on health claims, as much as ₹8 to 10 may be going to unjustified bills, manipulated documentation or systematically inflated costs.

For an industry that runs on relatively thin margins, this is not a rounding error. Such leakages are big enough to:

• Squeeze profitability
• Force higher pricing or narrower coverage
• Limit insurers’ appetite to expand into riskier or underserved segments

And because health insurance sits at the intersection of families, employers and the state, the cost ultimately flows back to consumers and taxpayers.

Where the fraud risk is highest: retail, reimbursement and “mid-ticket” claims

The Raksha Summit analysis uses large data sets to map “fraud propensity” across policy types and claim patterns. Instead of labelling everything as risky, it pinpoints where the danger really lies.

Retail vs group

Employer-provided group health and individually bought retail health behave very differently.

• Group policies typically have standardised terms, stable membership and a corporate HR team between the insurer and the employee.
• Retail policies are bought directly by individuals or families, often through fragmented intermediaries and with less institutional oversight.

The study finds higher fraud risk in retail health, especially for certain claim types, because verification is weaker and the perceived incentive to “recover” every rupee of premium is stronger at the household level.

Cashless vs reimbursement

The next big fault line is the mode of claim:

• In cashless claims, the hospital coordinates directly with the insurer or TPA, pre-approvals are common, and the transaction leaves a real-time digital trail.
• In reimbursement claims, the patient pays first, collects documents, and then approaches the insurer for repayment.

According to the report, retail reimbursement claims can show fraud risk an order of magnitude higher than group cashless claims. Put simply, “Retail + Reimbursement” is the danger zone.

When money and documentation move after treatment, there is more room for:

• Back-dated admissions and discharges
• Altered or fabricated invoices
• Swapping patient identities
• Mixing non-covered items into apparently standard packages

The “mid-ticket” sweet spot for fraud

The report also shows that fraud risk is most concentrated in the “mid-ticket” band, roughly between ₹50,000 and ₹2.5 lakh per claim.

This band is attractive to fraudsters because:

• The amounts are large enough to make manipulation worthwhile.
• They are not so large that they automatically trigger the toughest investigation protocols.
• Many common treatment packages naturally sit in this range, giving room to tweak codes and inflate costs without immediately standing out.

Fraud risk in claims below ₹50,000 is also rising, as opportunistic actors realise that low-value claims often pass with lighter sampling and less scrutiny.

Not all illnesses are equal: the high-risk medical categories

Using ICD-based disease groupings, the BCG study tracks how fraud propensity changes across medical categories.

One standout insight is that infectious disease claims carry much higher fraud risk than many other categories. The reasons are structural:

• These illnesses tend to be high volume – lots of cases and lots of claims.
• Symptoms can be vague – fever, pain, fatigue – making diagnosis subjective.
• Treatment patterns are often test-heavy, with long panels of investigations that are hard for patients to evaluate.

In comparison, many surgical procedures are relatively safer from a fraud perspective because they demand imaging, operation notes, multi-step approvals and more robust documentation.

The message is not that certain diseases are illegitimate. Instead, the report suggests that some claim categories are easier to game by design, and therefore require smarter, more focused checks.

How fraud looks on the ground: common scenarios

The Raksha Summit document lists typical fraud and abuse scenarios that appear repeatedly in both inpatient and outpatient claims.

Some of the most common patterns include:

Document fabrication
Bills, discharge summaries or prescriptions that have been edited, forged or created primarily to support a claim, rather than to reflect genuine treatment.

Impersonation and fake hospitalisation
Treatments carried out in the name of someone else’s policy, sometimes with collusion from low-oversight hospitals or small clinics. In a few cases, hospitalisation itself may be exaggerated or misrepresented.

Intentional non-cooperation
Patients or providers avoid responding to insurer queries, decline to share records, or provide contradictory versions of events when the investigation unit calls.

Non-existent or shell providers
Claims routed through entities that exist mostly on paper, with no real capacity to provide the level of care billed.

Over-packaging and unbundling
Breaking a single procedure into multiple items or tacking on unnecessary services to push up the bill, while still appearing medically plausible to the layperson.

These patterns are not unique to India, but the country’s fast-growing, unevenly digitised ecosystem makes it especially vulnerable if controls do not keep pace.

Why FWA persists: the systemic barriers

The BCG report spends considerable time on “systemic barriers” that allow fraud, waste and abuse to thrive. The problem is not just a few bad actors; it is an architecture that leaves too many gaps.

Key weaknesses include:

Fragmented data and weak interoperability
Claims, clinical records, policy data and provider credentials live in separate silos. Without robust data links and common formats, it is difficult to spot suspicious patterns across companies or over time.

Uneven provider governance
Large corporate hospitals may have internal audits and digital systems, but a big part of Indian healthcare is delivered through small facilities with patchy documentation and inconsistent processes.

Misaligned incentives
In fee-for-service models, more procedures and longer stays often mean more revenue. If contracts are loose and monitoring is weak, this naturally encourages waste and – in some cases – abuse.

Weak deterrence
Even when fraud is detected, follow-through can be slow or limited. If penalties are rare or invisible, the perceived risk of getting caught stays low.

Operational pressure at insurers and TPAs
Claims teams are expected to pay fast, keep customers happy and handle high volumes. It is impossible to deeply investigate every claim, so sampling and rule-based flags are used – and fraudsters learn to operate just below those thresholds.

In short, FWA persists because the system was not originally designed for integrity at today’s scale and complexity. The Raksha Summit report therefore argues for a re-design, not just more patchwork controls.

The BCG framework: Prevention, Detection, Deterrence

At the core of the report is a three-pillar framework for combating fraud, waste and abuse in Indian health insurance:

1. Prevention – reducing opportunities for fraud before claims are paid.
2. Detection – identifying suspicious behavior accurately and quickly.
3. Deterrence – ensuring meaningful consequences so that fraud does not look attractive.

Prevention: design for integrity, not just for volume

BCG emphasises a shift from reactive claims processing to proactive risk management, built on:

• Connected digital ecosystems that link ABHA IDs, hospital information systems, policy and claims data.
• Standardised codes, packages and tariffs, which reduce leeway for “creative” billing.
• More focus on preventive and primary care, which leads to more predictable utilisation and fewer opportunities for last-minute manipulation.

If data flows cleanly in real time, insurers can flag anomalies before money leaves the system instead of chasing it after settlement.

Detection: analytics plus disciplined operations

On detection, the report calls for a mix of technology and process:

• Advanced analytics and AI models to score claims, policies and providers on fraud risk, using historical patterns and external signals.
• Operational playbooks spelling out what happens when a claim crosses certain risk thresholds – from automatic document checks to field visits.
• Network analysis to uncover clusters of suspicious behaviour that may indicate organised fraud rings.

The idea is to concentrate human investigation effort where it counts most, while allowing low-risk, well-documented claims to move faster.

Deterrence: consequences and trust infrastructure

Detection without consequences does not change behaviour. BCG therefore calls for stronger deterrence mechanisms, including:

• Clear sanctions for proven fraud – such as de-empanelment, claw-back of payments, and legal action for organised scams.
• Industry-wide data sharing on high-risk entities, so that a provider blocked by one insurer cannot simply restart with another.
• Public and customer awareness, making it socially unacceptable to collude in seemingly “small” frauds and explaining how these leakages eventually hurt honest families.

Deterrence also has a positive side: rewarding integrity. Hospitals with strong documentation and low fraud risk can be given preferred-provider status and faster settlement; corporates with clean utilisation patterns can negotiate better terms.

What this means for insurers, hospitals and regulators

For India’s BFSI ecosystem, the Raksha Summit 2025 report reads like a strategic roadmap.

Insurers and TPAs
They will need to look beyond adding more investigators and instead:

• Invest in cleaner data pipelines and interoperable systems.
• Embed FWA control into product design, underwriting rules and provider contracts.
• Balance fraud control with customer experience so that genuine policyholders are not harassed.

Hospitals and providers
They will face growing pressure to:

• Standardise clinical and billing documentation.
• Integrate with digital health and insurance rails.
• Accept regular audits, peer comparisons and performance-linked contracts.

Those that adapt early can secure deeper, longer-term partnerships with insurers and gain more predictable cashflows.

Regulators and policymakers
They have to support both consumer protection and industry sustainability by:

• Encouraging interoperable data standards and adoption of the ABDM stack.
• Supporting common fraud registries and structured reporting frameworks.
• Ensuring that attempts to control fraud do not become excuses for unreasonable claim denials.

Employers and corporate buyers
They cannot treat fraud as purely “the insurer’s problem”. Governance around employee health benefits – including employee education, hospital choices and policy design – will directly influence future premiums.

Where policyholders fit in

Individual customers might feel far from the world of fraud analytics and regulatory frameworks, but they are directly affected by the outcomes.

Policyholders can play their part by:

• Buying insurance only through trusted channels, not from cold calls or dubious upgrade schemes.
• Being completely honest in proposal forms and medical declarations.
• Asking questions when tests or admissions are suggested without clear explanations.
• Refusing to participate in bill “adjustments” or padding, even if it is presented as a harmless way to “use the policy fully”.

Every fraudulent or inflated claim eventually shows up as higher premiums, stricter terms or tougher claims experience for everyone.

Rebuilding trust: the real challenge for Indian insurance

The BCG Raksha Summit 2025 report is ultimately about trust.

Health insurance in India is at a turning point:

• Coverage is expanding.
• Digital rails are becoming more powerful.
• The ambition of “Insurance for All” is widely shared.

But if the sector does not plug leakages from fraud, waste and abuse, the promise of affordable, reliable protection will remain fragile.

For readers of VenkatBFSI.com in banking, insurance, investing and policy circles, the message is clear:

• Controlling FWA is not a side issue; it sits at the heart of pricing, profitability and long-term growth.
• The Prevention–Detection–Deterrence framework offers a structured way forward.
• The real winners in the next decade will be those who build strong trust infrastructure while still delivering a humane, responsive experience to genuine customers.

In an industry built on promises for the worst days in people’s lives, integrity is not an add-on – it is the core product.
