AOE/COE & Workers' Compensation

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.

Frequently asked questions
What is an AOE/COE investigation in workers' compensation?
An AOE/COE investigation determines compensability: whether an injury arose out of employment and occurred in the course of employment. We run the full analysis from intake through a written determination report, built to California Labor Code 3600 and 3208 standards, with cross-jurisdictional coverage for multi-state carriers.
Why does the 90-day investigation window matter?
California gives carriers a 90-day window to make a good-faith compensability decision, and comparable good-faith requirements apply in other jurisdictions, so a slow start on a disputed claim is costly. We are built for rapid intake inside that window, and most cases can start within 24 to 48 hours.
What does a compensability investigation include?
It includes recorded statements taken in compliance with one- and two-party consent rules, on-site scene investigation and reconstruction, witness locate and interviews, and prior claims and medical history research through ISO ClaimSearch, CLUE, NICB ForeWarn, and medical canvass. HIPAA authorization is managed end to end.
Which workers' comp claims most often justify an AOE/COE referral?
Late-reported, Monday-morning, post-termination, and unwitnessed claims are the classic candidates. So are claims that turn on recurring doctrines and defenses: the going and coming rule, personal comfort and parking-lot injuries, intoxication, horseplay, and willful misconduct defenses, and telecommuting injuries where employer control is in question.
Can your investigation be used at the Appeals Board or trial?
Yes. Reports are ready for adjuster decision, Appeals Board review, and defense counsel use, and work product is prepared for deposition, trial, and appeals. Deliverables include recorded statement audio, transcripts, sworn reports, and court-ready scene and witness evidence with chain-of-custody documentation.
