Executive Summary
JIL Sovereign's premise-business compatibility rule engine detects fraud signals arising from mismatch between the business type billed on a claim or transaction and the physical premises the bill was generated from. A rule library declares compatibility rules, each comprising a billed-business-type pattern, a premise-feature pattern, and a compatibility verdict of allowed, suspicious, or prohibited.
Premise features are derived from a combination of street-view imagery classification, county-records square footage, business-license types registered to the address, and co-presence of unrelated business types at the same address. The engine evaluates every (billed-business-type, premise) pair against the library and emits a finding for any rule that fires with verdict suspicious or prohibited - capturing patterns such as hospice billing from personal-services premises, durable-medical-equipment vendors operating from residential addresses, and high-value procedures billed from premises lacking the physical infrastructure to perform them.
Problem Statement
Healthcare fraud, contractor fraud, and small-business loan fraud frequently involve incompatibility between the billed business type and the physical premises a business operates from. Detecting this requires correlating billed business type with premise characteristics - an analysis rarely performed by claim-only fraud platforms, even though the underlying premise data (street-view imagery, county records, business-license registries) is individually public and accessible.
Why Existing Solutions Are Insufficient
- Claim-coding anomaly detectors: examine CPT/HCPCS/ICD combinations, billing-rate outliers, and temporal patterns, but never look at where a bill physically originated.
- Individually-accessible premise data sources: street-view imagery, county records, and business-license databases exist but are not consolidated into a declarative compatibility rule library anywhere in production fraud tooling.
- Manual site-visit investigation: catches premise mismatch but does not scale to a claim population, and provides no systematic, versioned rule set an organization can improve over time.
Technical Architecture
Premise Feature Extraction
| Feature | Source |
|---|---|
| Signage business type | Street-view imagery, classified by an image classifier into a labeled business-type taxonomy with confidence scores |
| Square footage | County property records |
| Licensed business types | State/local business-license registries, current and historical |
| Co-presence | Count and list of other businesses registered to the same address |
| Zoning code / address type | Zoning databases and geocoding services (residential, commercial, mixed-use, industrial) |
An external data integrator fetches and caches these sources per premise, so multiple billing entities sharing a premise amortize the same fetch. A premise feature extractor assembles the cached outputs into a single structured feature record per premise.
Rule Library & Evaluation
Each rule declares: rule_id, a billed-business-type pattern (matched via NAICS code or free-text match), a premise-feature pattern, a compatibility verdict (allowed / suspicious / prohibited), a regulatory-basis identifier, a remediation-template identifier, and a severity. Patterns support equality, regex match, numeric range, set membership, and conjunction, for example:
billed_business_type IN {hospice, home-health}
AND premise.licensed_types CONTAINS personal-services -> suspicious
billed_business_type = ambulatory-surgery
AND premise.sqft < 1500 -> prohibited
A rule evaluator iterates the library in priority order for every (billing-entity, premise) pair and appends a finding on any match. Findings include the rule identifier, the billing entity, the premise feature record, the verdict, and source-data citations for every premise feature that contributed to the match - so every finding is independently auditable back to its street-view frame, county record, or license filing.
Rule Lifecycle & Validation
New rules can be added by an authorized operator at runtime without code redeployment; every addition is written to an append-only audit log. Rules support time-bounded scoping, so a rule applies only to claims dated within a specified period - allowing the library to track regulatory changes such as new zoning rules taking effect on a given date. Each rule also declares a confidence score that findings inherit, letting investigators triage the highest-confidence matches first.
The initial ~40-rule library detects hospice-from-personal-services, DME-from-residential, and ambulatory-surgery-from-undersized-premise patterns at high precision, validated against a synthetic multi-entity test scenario spanning tens of thousands of claims with a substantial share of confirmed premise mismatches - demonstrating that the architecture surfaces coordinated-premise fraud patterns that claim-coding review alone does not catch.
