Clinical Environmental Intelligence

Close the exposure gap in your practice

The average physician receives just 7 hours of environmental health training in medical school. Homeknown gives your practice the clinical infrastructure to assess, quantify, and act on patient environmental exposures — with built-in billing support.

The Clinical Exposure Gap

Your patients are exposed. Your tools aren't keeping up.

Patients present with complex, multi-system complaints that don't resolve with standard care. Without a framework to investigate environmental triggers, clinicians manage symptoms instead of addressing root causes.

No Standardized Intake

Environmental history is collected through unstructured patient narratives, if at all. There is no consistent framework for capturing exposure data across visits or practice settings.

No Interpretive Layer

Even when exposures are documented, there is no decision-support system to connect suspected exposures to specific diagnostic pathways, ICD-10 codes, or recommended lab panels.

Fragmented & Costly Testing

Lab panels are spread across numerous providers, are rarely covered by insurance, and lack integrated clinical interpretation. Patients bear the burden of navigating a broken system.

No Billing Infrastructure

Physicians lack clarity on how to code and bill for environmental health services, leaving revenue on the table and discouraging the integration of exposure assessment into routine care.

How It Works

From survey to clinical action in four steps

Homeknown integrates seamlessly into your existing workflow. No new EMR required. No software to install. Just a secure link and a clinical report.

01

Assign the Survey

Generate a unique, secure survey link for your patient — or send it directly via email or SMS from the dashboard.

02

Patient Completes EBI

The patient answers questions about their home environment, water sources, air quality, materials, and daily habits.

03

Report Generated

Homeknown generates a scored Clinical EBI™ report with vector analysis, exposure categories, and suggested ICD-10 / CPT pathways.

04

Review & Order

Review the report in your dashboard. Order recommended lab panels and monitoring devices directly — billed to practice or patient.
