Upload CSV File for Batch PSI Risk Analysis
Upload a CSV file containing multiple patients' diagnosis codes for PSI risk variable analysis using Elixhauser comorbidity methodology.
CSV Format Requirements:
- Required columns:
patient_id,sequence,icd_code,poa_status - Each row represents one diagnosis for a patient
- Sequence numbers must include 1 for primary diagnosis
- POA status must be one of: Y, N, E, W, U
- ICD-10 codes can be entered with or without decimals
- Primary diagnoses (sequence 1) will not receive risk variable assignments
File Size Limits:
- Maximum file size: 1MB
- Maximum rows: 20,000
- If your file exceeds these limits, consider splitting it into smaller batches
HIPAA Compliance - No PHI:
- Patient IDs must be de-identified (no names, SSNs, MRNs, or other PHI)
- Use anonymous patient numbers or study IDs only
- Do not include patient names, dates of birth, addresses, or any identifiable information
- This tool processes diagnosis codes only - no PHI is stored or transmitted
Sample CSV Format
Important: Patient IDs below are examples of de-identified numbers. Do not use real patient identifiers.
patient_id,sequence,icd_code,poa_status 12345,1,I50.1,Y 12345,2,I10,Y 12345,3,E11.9,Y 67890,1,I50.9,Y 67890,2,J44.1,Y 67890,3,N18.3,Y
Note: Primary diagnoses (sequence 1) do not receive risk variable assignments in PSI methodology. Secondary diagnoses will be analyzed for Elixhauser comorbidity risk variables based on POA status and trigger rules.
