AOE/COE and Workers' Comp Claim Investigation
The Investigation the File Needs, Inside the 90-Day Window
California's 90-day investigation window, and comparable good-faith requirements in other jurisdictions, means carriers, TPAs, and self-insured employers cannot afford a slow start on a disputed claim. Our claims investigators are built for this. We run AOE/COE compensability investigations, take recorded statements, document the scene, locate witnesses, and pull prior claims and medical history. Reports are ready for adjuster decision, appeals board review, and defense counsel use.
Doctrines & Defenses
The AOE/COE Questions That Drive Claims
Most AOE/COE fights come down to a short list of recurring doctrines and affirmative defenses. Investigating the right facts, in the right order, and documenting them correctly is the difference between a compensability call that holds up and one that gets reversed on appeal.
Key Doctrines We Investigate
- Going and Coming RuleCommute injuries are generally not compensable. But three exceptions frequently apply: special mission, commercial traveler, and employer-provided transport. Each requires investigation.
- Personal Comfort & Parking LotBreak, restroom, meal, and parking-lot injuries often fall within the course of employment. Location, employer control, and the claimant's activity at the time determine the outcome.
- Defenses: Intoxication, Horseplay, Willful MisconductThese defenses can defeat compensability. But they only hold up when the investigation shows the conduct caused the injury, not just that it occurred.
- Telecommuting & Work-From-HomeRemote-work injuries create compensability questions that older case law never addressed. We investigate the home-office setup, what the claimant was doing at the time of injury, and the extent of employer control.
