EXPOSURE BURDEN INDEX · ENVIRONMENTAL HEALTH ASSESSMENT
Composite score derived from 5 environmental exposure vectors, weighted by symptom correlation and vulnerability factors.
Symptom duration: 6-12 months · CPT: 96160 (Health Risk Assessment Instrument)
Individual environmental exposure scores (0–100 scale). Scores above 60 trigger clinical decision pathways.
Aggregated symptom severity by clinical cluster. Higher scores indicate greater symptom burden in that system.
Key environmental factors reported by the patient.
4 pathway(s) generated based on exposure-symptom correlation analysis. These are suggestions to support clinical decision-making; all ordering and interpretation is at the clinician's discretion.
Well-water exposure with unknown pipe age (pre-1978), proximity to contamination site, and visible water quality issues indicate elevated risk for PFAS, lead, and other waterborne contaminants.
Confirmed water damage and visible mold in a carpeted home, combined with respiratory symptoms (sinus congestion, shortness of breath, wheezing) that improve when leaving the home.
Gas stove, attached garage, no radon testing, and pre-1978 construction contribute to elevated indoor air quality risk. Radon testing is recommended as a priority.
Pre-1978 home with unknown pipe material and proximity to contamination site. While the score is below the priority threshold, the combination of factors warrants baseline heavy metal screening.
Based on the exposure profile, the following additional testing tiers may provide actionable data.
Tap Score Advanced City Water Test (111 analytes) including PFAS, lead, pesticides, and other contaminants. EPA-certified lab analysis.
Strongly RecommendedEnviroBiomics ERMI mold analysis. 36-species mold panel using EPA-developed gold standard methodology for CIRS evaluation.
Strongly RecommendedThis report is generated by the HomeKnown Exposure Burden Index (EBI) scoring engine based on patient-reported environmental and symptom data. It is intended to support clinical decision-making and does not constitute a medical diagnosis, treatment recommendation, or guarantee of any outcome.
All lab ordering, interpretation, and clinical decisions remain the responsibility of the ordering physician. HomeKnown does not order, perform, or interpret medical laboratory tests. Suggested lab panels and billing codes are provided as reference material to support medical necessity documentation.
Insurance coverage for environmental health assessments varies by plan and payer. Patients should verify coverage with their insurance provider. Environmental monitoring and testing services may be HSA/FSA eligible with a Letter of Medical Necessity (LMN).
