Insurance companies are pushing back on ADAS calibration charges more aggressively than ever. First-level adjusters are trained to question calibration charges that aren't immediately obvious from the damage description, and some carriers have internal policies that treat calibration as a negotiating point rather than a required procedure. Shops that know how to respond -with specific documentation and a systematic process -win these disputes. Shops that accept the first denial don't.
Why Denials Happen
Most ADAS supplement denials happen for one of three reasons: missing OEM procedure documentation, insufficient scan documentation, or the charge being coded incorrectly. Adjusters who see a calibration charge with no OEM backup, no scan reports, and a generic labor code have a reasonable basis to question it. The shop's job is to eliminate every one of those objections before the denial even arrives -by front-loading the documentation in the initial submission.
Your First Response: The OEM Position Letter
When a calibration charge is denied, the first response is a copy of the OEM repair procedure requiring the calibration, along with the OEM's position statement on post-repair calibration requirements. Every major manufacturer -Toyota, Honda, Ford, GM, BMW, Mercedes -has published position statements affirming that ADAS calibration is required after specific repair events. These documents are available through SCRS, OEM repair information portals, and industry associations. They're powerful because they remove the shop's assertion from the argument and replace it with the manufacturer's requirement.
Pre and Post Scan Reports as Evidence
A pre-scan showing ADAS-related fault codes before the repair, and a post-scan showing those codes resolved after calibration, is the most compelling supplement evidence available. It demonstrates that the fault existed, that calibration was necessary to resolve it, and that the vehicle was verified to be operating correctly at delivery. Pair the scan reports with the OEM procedure document and you've built an argument that's very difficult to sustain a denial against.
Escalation Works -When You Have Documentation
If the first appeal is denied, escalate to a supervisor or regional claim manager. Request a conversation rather than a written response -supervisors often have more flexibility than line adjusters. Come to that conversation with your OEM documentation, your scan reports, and a specific reference to the manufacturer's calibration requirement. Document the conversation and follow up in writing. Persistence backed by evidence is how shops consistently win ADAS supplement disputes.
