Dataset Summary

INS-007 simulates the full fraud claims investigation lifecycle — from claim intake through SIU referral, surveillance, forensic investigation, and adjudication — with realistic ring-based fraud structures, staged accident typologies, and ISO ClaimSearch-calibrated red flag scoring.

Calibration sources:

• Coalition Against Insurance Fraud — confirmed fraud rates, savings
• FBI Insurance Fraud Annual Report — organized ring fraud share
• NAIC AS-101 — Anti-Fraud Plan regulations and SIU referral rates
• Insurance Research Council (IRC) — attorney representation rates
• ISO ClaimSearch — red flag indicator catalog and scoring
• NICB ForeWARN — staged accident pattern typologies

9 lines of business with empirically-anchored fraud rates:

• Auto bodily injury (28%) — highest fraud rate LOB
• Auto property damage (18%)
• Auto PIP / no-fault (14%) — high fraud rate in no-fault states
• Workers compensation (12%)
• Homeowners (10%)
• Commercial property (6%)
• Health (5%)
• General liability (4%)
• Disability (3%)

8 staged accident pattern typologies (NICB-calibrated):

• Swoop-and-squat
• Drive-down
• Side-swipe
• Rear-end setup
• Paper accident (no actual collision)
• Owner give-up (insurance dump)
• Medical mill only (no accident at all)

12 fraud type confirmations (post-investigation):

• Staged accident
• Soft fraud / exaggeration
• Medical billing fraud
• Provider fraud (corrupt medical / repair providers)
• Agent fraud (corrupt agent / broker)
• Owner give-up
• Workers comp fraud
• Disability fraud
• Slip and fall fraud
• Fire loss fraud
• Water damage fraud
• Ring-organized fraud (multi-party coordinated)

Fraud ring social network:

• 60 fraud rings in sample (full product: ~150 rings)
• Average ring size 5-15 members
• Shared attributes: addresses, phone numbers, attorneys, body shops, medical providers, witnesses
• 435 network edges in sample (full product: ~5,000)
• Edge types: same_ring, shared_address, shared_phone, shared_attorney, shared_body_shop, shared_medical_provider, shared_witness

SIU investigation workflow:

• SIU referral with reason taxonomy
• Surveillance conducted flag
• Recorded statement taken
• Statement inconsistency count
• Investigation duration
• Outcome (paid_no_siu, paid_post_siu_legitimate, settled_with_reduction, denied_unsubstantiated, denied_fraud_confirmed, withdrawn_by_claimant, referred_to_da, criminal_prosecution, civil_recovery)
• Savings achieved (avoided loss)
• Recovery amount (post-payment clawback)

Red flag scoring (40+ binary indicators with prefix rf_):

• Claimant red flags: prior_claims_history, gaps_in_treatment, no_witnesses
• Provider red flags: medical_mill_pattern, billing_anomalies, shared_attorney_concentration
• Vehicle red flags: salvage_history, pre_existing_damage, phantom_vehicle
• Network red flags: shared_address, shared_phone, shared_body_shop
• Statement red flags: inconsistent_statements, recorded_changes
• Behavioral red flags: late_reporting, policy_lapse_pre_loss, coverage_recently_increased
• ISO ClaimSearch-calibrated weights

Red flag composite score (0-100):

• Computed weighted score across all triggered red flags
• Cleanly separates fraud (mean 50.1) from legitimate (mean 7.2)
• Direct feature for ML model training

Claim-level features:

• Claim ID with structured format (CLM-YEAR-LOB-STATE-SEQ)
• Loss date, claim filing date, age of claim
• Claim amount demanded, paid, savings, recovery
• Medical billing amount
• Estimated fraud savings (counterfactual avoided loss)

Calibrated Validation Results

Sample validation results across 10 fraud-detection KPIs:

Metric	Observed	Target	Source	Verdict
n_states_represented	50	12	Min state coverage (national mix)	✓ PASS
n_lob_represented	9	9	9 lines of business	✓ PASS
confirmed_fraud_rate_pct	10.14	10.00	Coalition Against Ins Fraud	✓ PASS
siu_referral_rate_pct	16.12	16.00	NAIC AS-101 SIU referral rate	✓ PASS
ring_based_fraud_share_pct	9.90	10.00	FBI organized fraud share	✓ PASS
attorney_representation_pct	30.10	30.00	IRC attorney rep (high-suspicion)	✓ PASS
surveillance_conducted_pct	10.70	10.00	SIU surveillance industry rate	✓ PASS
police_report_filed_pct	71.84	70.00	Auto-heavy LOB police report rate	✓ PASS
red_flag_separation_ratio	6.938	6.000	RF score: confirmed/legit ratio	✓ PASS
n_fraud_ring_edges	435	200	Network edge density (floor)	✓ PASS

Note: Confirmed fraud rate (~10%) is below the configured --fraud-rate 0.18 parameter because only ~56% of fraud-suspect claims that get SIU referral end in fraud_confirmed=True after investigation. The other ~44% of suspected fraud is resolved as paid_post_siu_legitimate, settled_with_reduction, denied_unsubstantiated, or withdrawn — realistic SIU workflow outcomes. This makes INS-007 useful for training models that distinguish suspected from confirmed fraud, not just legitimate from suspicious.
