Building a Special Investigations Unit (SIU) for a Pet Insurance MGA

Every dollar paid on a fraudulent claim is a dollar stolen from your loss ratio. An SIU is your defense the team that takes flagged claims from suspicion to resolution. You don't need a 10-person department on day one. You need a clear process, qualified people, and the authority to investigate. Here's how to build SIU capability that scales with your MGA.

Why Does a Pet Insurance MGA Need SIU Capability?

A pet insurance MGA needs SIU capability because an estimated 5–10% of pet insurance claims involve fraud, costing 3–7 loss ratio points annually and without a dedicated investigation function, less than 20% of fraud is detected compared to 40–60% with an SIU. Most states also require insurers to maintain an anti-fraud plan, which the SIU fulfills.

1. The Fraud Problem

Metric	Pet Insurance Reality
Estimated fraud rate	5–10% of claims
Loss ratio impact	3–7 points
Annual cost ($10M premium)	$300K–$700K
Most common fraud	Invoice inflation, pre-existing concealment
Detection without SIU	<20% of fraud identified
Detection with SIU	40–60% of fraud identified

2. Regulatory Requirements

Requirement	Details
Anti-fraud plan	Required in most states
Fraud reporting	Must report confirmed fraud to state bureau
SIU designation	Must have designated fraud investigation function
Training	Claims staff must receive fraud awareness training
Record keeping	Investigation files retained per state requirements

How Should You Structure an SIU Based on MGA Size?

You should scale your SIU structure based on policy count: designate a senior adjuster as part-time fraud lead at 0–5,000 policies, hire a dedicated investigator at 5,000–10,000, build a 2-person team at 10,000–25,000, expand to 3–4 FTEs with vendor support at 25,000–50,000, and create a full enterprise unit with analytics at 50,000+ policies.

1. Scaling Your SIU

MGA Size	SIU Model	Staffing	Annual Cost
0–5,000 policies	Designated fraud lead	Senior adjuster (part-time)	$10K–$20K incremental
5,000–10,000	Dedicated investigator	1 FTE SIU	$80K–$120K
10,000–25,000	Small SIU team	2 FTEs (investigator + analyst)	$160K–$250K
25,000–50,000	Full SIU	3–4 FTEs + vendor support	$300K–$500K
50,000+	Enterprise SIU	5+ FTEs + analytics + vendor	$500K+

2. Outsource vs In-House

Factor	In-House	Outsourced
Cost	Higher fixed, lower per-case	Lower fixed, higher per-case
Control	Full control	Less direct control
Expertise	Must recruit	Immediate access
Scalability	Slower to scale	Flexible capacity
Institutional knowledge	Builds over time	Limited
Best for	10,000+ policies	<10,000 policies or surge capacity

3. SIU Investigator Profile

Qualification	Importance
Insurance fraud investigation experience	Critical
CFE or CIFI certification	Highly preferred
Interview and interrogation skills	Critical
Evidence documentation	Critical
Regulatory reporting knowledge	High
Pet insurance knowledge	Preferred (can learn)
Law enforcement background	Valued
Data analysis skills	High

What Does the SIU Investigation Workflow Look Like?

The SIU investigation workflow follows eight steps from referral to resolution: claim flagged by adjuster or rules engine, SIU triage and priority assignment within 1–2 days, case opening, evidence gathering over 1–3 weeks, active investigation with interviews and analysis over 1–4 weeks, fraud determination, action taken (denial, rescission, reporting), and case closure with full documentation.

1. Referral to Resolution

Step	Action	Timeline	Owner
1. Referral	Claim flagged by adjuster or rules engine	Day 0	Claims team
2. Triage	SIU reviews referral, assigns priority	1–2 days	SIU lead
3. Case opening	Create investigation file, notify claims	Day 2–3	SIU investigator
4. Evidence gathering	Request records, analyze data	1–3 weeks	SIU investigator
5. Investigation	Interviews, verification, analysis	1–4 weeks	SIU investigator
6. Determination	Fraud confirmed, suspected, or cleared	End of investigation	SIU lead
7. Action	Deny claim, rescind policy, report	Per determination	SIU + claims
8. Closure	Document outcome, close file	1 week post-action	SIU investigator

2. Referral Criteria

Red Flag	Priority	Action
Claim within 14 days of enrollment	High	Full investigation
Invoice >3x condition average	Medium	Evidence gathering
Multiple claims in 30 days (new policy)	High	Pattern analysis
Same vet, multiple flagged claims	High	Provider investigation
Prior insurer fraud history	High	Full investigation
Inconsistent medical records	Medium	Records review
Claim just below review threshold	Low	Monitoring

What Are the Evidence Standards for SIU Investigations?

The evidence standards for SIU investigations require multiple types of proof documentary evidence (medical records, invoices, applications) carries the highest weight, supported by digital evidence (system logs, timestamps), testimonial evidence (vet and claimant statements), and analytical evidence (statistical anomalies) all collected with proper chain of custody and documentation for regulatory and legal admissibility.

1. What Constitutes Evidence

Evidence Type	Examples	Weight
Documentary	Medical records, invoices, applications	High
Digital	System logs, IP addresses, timestamps	Medium-High
Testimonial	Vet statements, claimant statements	Medium
Analytical	Statistical anomalies, peer comparison	Supporting
Third-party	Prior insurer records, public records	High

2. Evidence Collection Best Practices

Practice	Why It Matters
Document everything in writing	Creates admissible record
Obtain records directly from source	Avoids tampering allegations
Maintain chain of custody	Required for legal proceedings
Use standardized forms	Ensures completeness
Record interview dates and participants	Creates verifiable timeline
Preserve digital evidence	Screenshots, system logs

3. Investigation File Contents

Section	Documents
Referral	Original fraud referral form, red flags identified
Claim file	Complete claim documentation, adjudication notes
Policy file	Application, underwriting notes, policy documents
Medical records	Vet records from treating vet and prior vets
Financial records	Payment records, invoice analysis
Correspondence	All communications with claimant, vet, others
Analysis	Peer comparison, timeline analysis, findings
Determination	Final report, recommendation, approval
Action	Denial letter, rescission notice, fraud report

What Are the Regulatory Reporting Requirements for Confirmed Fraud?

When fraud is confirmed, the SIU must report to the state fraud bureau within 30–60 days of determination (timeline varies by state), using state-specific forms with supporting evidence, filed by the designated fraud contact with investigation files retained for 5–7 years and good faith reporting providing statutory immunity protection.

1. State Fraud Bureau Reporting

Element	Requirement
When to report	Confirmed fraud, within 30–60 days (varies by state)
What to report	Suspected fraud with supporting evidence
How to report	State-specific forms (many accept NAIC format)
Who reports	SIU lead or designated fraud contact
Record retention	5–7 years (varies by state)
Immunity	Good faith reporting provides statutory immunity

2. Reporting Workflow

Step	Action	Timeline
1	Complete investigation, confirm fraud	End of investigation
2	Prepare fraud report with evidence summary	Within 5 business days
3	SIU lead reviews and approves report	Within 2 business days
4	Submit to state fraud bureau	Within 30 days of determination
5	Retain copy in investigation file	Permanent retention
6	Report to carrier (per MGA agreement)	Per agreement timeline

For fraud reporting requirements, see our regulatory guide.

How Do You Measure SIU Performance and ROI?

You measure SIU performance through seven KPIs: referral volume trends, investigation closure rate (target 85%+ within 60 days), confirmed fraud rate (30–50% of investigations), annual fraud savings, recovery rate (10–20%), referral quality improvement, and false positive rate (target below 50%) with a well-run SIU delivering 2.5–6x ROI annually.

1. Key Performance Indicators

Metric	Target	Calculation
Referral volume	Track trend	Referrals per 1,000 claims
Investigation closure rate	85%+ within 60 days	Closed / opened per period
Confirmed fraud rate	30–50% of investigations	Confirmed / investigated
Fraud savings	Track annually	Denied fraudulent claims $
Recovery rate	10–20% of confirmed fraud	Recovered $ / confirmed fraud $
Referral quality	Improving over time	Confirmed / referred
False positive rate	<50%	Cleared / investigated

2. ROI Calculation

Component	Annual Value
SIU cost (1 investigator)	($100K–$130K)
Claims denied (fraud confirmed)	$200K–$500K
Deterrence effect (estimated)	$100K–$300K
Premium saved (lower loss ratio)	$50K–$150K
Net ROI	$250K–$820K
ROI multiple	2.5–6x

Frequently Asked Questions

1. What is an SIU?

A dedicated team investigating suspected insurance fraud from flagged claims through evidence gathering, determination, and regulatory reporting.

2. When should you build one?

Designate a fraud lead immediately. Hire a dedicated investigator at 5,000–10,000 policies. Build a team at 25,000+. Outsource at any stage.

3. What qualifications do investigators need?

CFE or CIFI certification preferred. Insurance fraud investigation experience, interview skills, evidence documentation, and regulatory reporting knowledge.

4. What happens when fraud is confirmed?

Deny the claim, report to state fraud bureau (required), consider policy rescission, and refer to law enforcement for significant cases.

5. What is the ROI of an SIU?

A single investigator costing $100K–$130K typically generates $250K–$820K in net ROI through denied fraudulent claims, deterrence effects, and lower loss ratios — a 2.5–6x return on investment.

6. Should you outsource or build in-house?

Outsource below 10,000 policies or for surge capacity. Build in-house above 10,000 for full control and institutional knowledge. Many MGAs use a hybrid approach combining both.

7. What are the most common pet insurance fraud types?

Invoice inflation by veterinary clinics, concealment of pre-existing conditions, duplicate claims to multiple insurers, fabricated treatment claims, and organized fraud schemes involving collusion between pet owners and providers.

8. What red flags trigger an SIU investigation?

Claims within 14 days of enrollment, invoices exceeding 3x condition average, multiple claims in 30 days on new policies, the same vet on multiple flagged claims, prior fraud history, inconsistent medical records, and claims just below review thresholds.
