How to Analyze Health TPA Stocks in India: PUM & Retention
Team QuartrlyHealth Third Party Administrator (TPA) stocks in India — a narrow field led by the listed player Medi Assist — are graded not on premium growth but on Premium Under Management (PUM), corporate client retention above 90%, and the spread between claim-size growth and medical inflation. Because TPAs are paid a fixed fee per life or per policy rather than a cut of the premium, rising medical inflation squeezes their economics instead of lifting them the way it lifts insurers: Medi Assist's Q2 FY26 numbers show PUM at ₹12,719 crore (up 20.2% YoY) against a Group retention rate of 93.4%. Reading this sector well means checking fraud-detection savings (FWA) and network exclusivity alongside those headline numbers to see whether growth is being bought at the cost of margin.
Key Takeaways
- Premium Under Management (PUM) indicates scale, but revenue growth depends on lives covered, not just premium value
- Retention Rate above 90% signals strong client relationships and operational excellence
- The Inflation Spread (claim growth vs. medical inflation) measures a TPA's core value proposition to insurers
- FWA Savings demonstrate fraud detection capabilities and justify the TPA's role in the value chain
- Network Exclusivity reflects insurer dependency and competitive positioning

Understanding Health TPA Metrics
Health TPAs operate fundamentally differently from insurers. While insurers bear underwriting risk and earn from premiums minus claims, TPAs are service providers paid on a per-life or per-policy basis. Their revenue is largely disconnected from premium inflation — a policy that costs ₹10,000 or ₹15,000 may generate the same TPA fee.
This creates a unique dynamic: medical inflation benefits insurers (higher premiums) but challenges TPAs (more complex claims to process for similar fees). Investors must evaluate TPAs on operational efficiency, client retention, and fraud detection capabilities rather than traditional insurance metrics like loss ratios or combined ratios.
Premium Under Management (PUM)
What it is: PUM represents the total value of insurance policies administered by the TPA. It is analogous to Assets Under Management (AUM) for asset managers — indicating scale of operations rather than direct revenue.
Why it matters: PUM reflects the TPA's market position and ability to win contracts from insurers and corporate clients. Higher PUM typically correlates with greater bargaining power with hospital networks and more data for fraud detection algorithms.
What good looks like: Double-digit PUM growth exceeding industry health insurance growth indicates market share gains. Medi Assist reported PUM of ₹12,719 crore as of September 2025, representing 20.2% YoY growth.
Red flag: PUM growth without corresponding revenue growth suggests fee compression or adverse client mix shifts toward lower-margin contracts.
Example from earnings call:
"Total Premium under Management administered was INR 12,719 crore as on 30th Sep 2025, a growth of 20.2% YoY." — Medi Assist Q2 FY26 Earnings Call
Retention Rate
What it is: Retention Rate measures the percentage of corporate (Group) clients that renew their TPA relationship, typically calculated on an annual basis. It excludes portfolio acquisitions to show organic client loyalty.
Why it matters: In a business with high customer acquisition costs and long sales cycles, retention is critical. A TPA that retains clients even when the underlying insurer changes demonstrates superior service quality and embedded value.
What good looks like: Retention rates above 90% indicate strong client relationships. Medi Assist consistently maintains retention around 93-94% for Group accounts.
Red flag: Retention below 85% may indicate service quality issues, competitive pricing pressure, or loss of key corporate relationships.
Example from earnings call:
"Achieved a retention rate of ~93.4% for Group accounts across corporates, excluding Paramount portfolio." — Medi Assist Q2 FY26 Earnings Call
Inflation Spread (Claim Growth vs. Medical Inflation)
What it is: The Inflation Spread measures the difference between industry medical inflation and the TPA's average claim size growth. It quantifies how effectively the TPA controls costs through hospital negotiations and claims management.
Why it matters: Insurers hire TPAs specifically to contain claim costs. A TPA that keeps claim growth significantly below medical inflation delivers measurable value and justifies its fees. This metric directly demonstrates the TPA's negotiation leverage with hospital networks.
What good looks like: Claim size growth at less than 50% of the medical inflation rate represents strong performance. With medical inflation at 10-12%, claim growth below 5-6% indicates effective cost containment.
Red flag: Claim growth approaching or exceeding medical inflation suggests loss of negotiating leverage with hospitals or deteriorating claims management processes.
Example from earnings call:
"Average claim size growth for Medi Assist continues to be substantially lower at 4.4% as against industry medical inflation of 10-12%." — Medi Assist Q2 FY26 Earnings Call
FWA Savings (Fraud, Waste, and Abuse)
What it is: FWA Savings represent the monetary value of claims rejected or reduced due to fraudulent billing, unnecessary procedures, or billing errors. This metric quantifies the TPA's fraud detection and claims audit capabilities.
Why it matters: FWA savings directly reduce the insurer's claims outgo and justify the TPA relationship. Growing FWA savings indicate improving detection algorithms and audit processes, making the TPA increasingly indispensable.
What good looks like: Consistent growth in absolute FWA savings, particularly triple-digit crore figures. Medi Assist reported approximately ₹160 crore in FWA savings in Q1 FY26, representing a 3x increase YoY.
Red flag: Flat or declining FWA savings may indicate outdated detection systems, reduced audit rigor, or saturation of obvious fraud cases.
Example from earnings call:
"Fraud, Waste, and Abuse savings reached approximately INR 160 crore, marking a 3x increase YoY." — Medi Assist Q1 FY26 Earnings Call
Network Exclusivity
What it is: Network Exclusivity measures the number of insurers that exclusively use a TPA's hospital network for claims processing. It indicates the depth of the relationship beyond basic claims administration.
Why it matters: When insurers adopt a TPA's network exclusively, switching costs increase substantially. This creates a moat and provides pricing power in contract renewals.
What good looks like: A growing number of exclusive network partnerships. Medi Assist's network was adopted exclusively by 19 insurers in H1 FY26, up from 17 in H1 FY25.
Red flag: Declining exclusive partnerships or insurers building their own hospital networks indicates weakening competitive position.
Example from earnings call:
"Medi Assist network adopted exclusively by 19 insurers in H1 FY26, up from 17 in H1 FY25." — Medi Assist Q2 FY26 Earnings Call
Cashless Ratio
What it is: The Cashless Ratio represents the percentage of claims settled through direct hospital-insurer payment (cashless) versus reimbursement to the policyholder after out-of-pocket payment.
Why it matters: Cashless claims require real-time authorization and TPA infrastructure. Higher cashless ratios indicate operational efficiency, better hospital network integration, and superior customer experience.
What good looks like: Cashless ratios above 80% for Group policies indicate mature operational capabilities and strong hospital relationships.
Red flag: Cashless ratios below 70% may indicate network gaps, authorization delays, or operational inefficiencies that reduce customer satisfaction.
Group vs. Retail Mix
What it is: This metric shows the proportion of policies managed from corporate (Group) clients versus individual (Retail) policyholders. The two segments have different economics and operational requirements.
Why it matters: Group policies offer volume and predictability but typically carry lower margins. Retail policies require higher touch service but offer better unit economics. A diversified mix provides both stability and growth potential.
What good looks like: A predominantly Group portfolio (70-80%) with growing Retail contribution provides operational leverage while building higher-margin revenue streams.
Red flag: Excessive concentration in Group (above 90%) creates client concentration risk and limits margin expansion potential.
Revenue per Employee
What it is: Revenue per Employee is calculated by dividing total revenue by the number of employees. It measures workforce productivity in this labor-intensive service business.
Why it matters: TPAs are fundamentally service businesses where claims processing, customer service, and hospital coordination require significant headcount. Improving revenue per employee indicates successful automation, process optimization, or favorable business mix shifts.
What good looks like: Consistent year-over-year improvement in revenue per employee, typically 5-10% annually for well-managed TPAs implementing automation initiatives.
Red flag: Declining revenue per employee despite revenue growth suggests inefficient scaling or adverse business mix changes.
Special Consideration: The Per-Life Fee Structure
A critical nuance for TPA investors is understanding fee structures. Many TPA contracts charge a fixed fee per life or per policy rather than a percentage of premium. This means when medical inflation increases premiums by 15%, the insurer captures the additional premium while the TPA processes higher-value claims for the same fee.
The implication: PUM growth alone can be misleading. Investors should track "Lives Covered" or "Policy Count" alongside PUM. If PUM grows 20% but lives covered grow only 5%, the TPA is processing more expensive policies without proportional fee increases — essentially working harder for similar compensation.
