Always test with trading partners in test mode first
Validate all transaction formats before production
Implement comprehensive error handling
Monitor acknowledgment rates

2. Performance

Use batch processing for high-volume transactions
Implement proper retry logic
Monitor transaction response times
Set appropriate timeout values

3. Compliance

Maintain current HIPAA compliance documentation
Regular security audits
Keep trading partner agreements updated
Monitor regulatory changes

4. Monitoring

Set up alerts for failed transactions
Track acknowledgment rates
Monitor system performance
Regular compliance reviews

Troubleshooting

Common Issues

1. Transaction Rejected (997/999)

Check segment structure
Validate required elements
Verify trading partner setup
Review business rules

2. Connection Timeouts

Verify network connectivity
Check firewall settings
Adjust timeout values
Verify trading partner availability

3. Data Validation Errors

Review field formats
Check code sets (ICD-11, CPT)
Validate NPI numbers
Verify date formats
