Other driver's insurance accepted 100% fault — why does my repair bill still show I owe money?

I went through almost this exact thing last year. What happened in my case was the shop was just formatting their estimate weird — they were showing what my OWN insurance would cover vs. my deductible, even though I was actually going through the at-fault driver's policy. Once I clarified with the shop that I was a third-party claimant (not going through my own coverage), the "amount owed" line disappeared. Worth double-checking which policy the shop actually has on file.

Don't assume that "accepting full liability" means they'll just write a blank check without pushback. Insurers say that phrase and then quietly try to introduce things like "betterment charges" or dispute certain line items on the estimate. That "customer owes" amount might be one of those. Ask the adjuster to send you something in writing that breaks down exactly what they're refusing to cover and why. If they can't justify it, push back hard.

Former adjuster here. A few things could be happening. First — and most likely — the shop entered your claim as if it were going through YOUR collision coverage, which would mean your deductible shows up. That's a data entry issue, not a real obligation. Second possibility: the at-fault insurer is only paying what they call "prevailing rate" for parts or labor, and anything above that gets passed to you. That second scenario is genuinely worth challenging. Call the liability adjuster directly (not the shop) and ask them to confirm in plain language that your out-of-pocket should be zero. Get it in writing if you can.

Just to clarify the deductible thing since it confused me too when I first started working around these cases: deductibles are a feature of your policy, not the at-fault party's. When you're a third-party claimant on someone else's liability coverage, there is no deductible applied to you. So if that line on the estimate really is a deductible, it shouldn't be there. The shop might just be using a template that auto-populates that field.

Call the at-fault driver's insurance adjuster today. Don't go through the shop as a middleman. Tell them exactly what you told us — they accepted full liability, and you need confirmation that your out-of-pocket is zero before you authorize repairs. Get the adjuster's name, get a confirmation number, and ideally get an email. This is probably a simple mix-up but you want it sorted BEFORE the car goes into the shop, not after.

Ugh, this sounds so stressful on top of already dealing with the accident itself. I hope you're doing okay physically. Don't let them railroad you into paying something you don't owe — you did nothing wrong here.

Can you share more about what the estimate actually says? Like is the word "deductible" used anywhere, or does it say something else like "non-covered amount" or "customer responsibility"? The exact wording matters a lot here because those could mean very different things and the fix for each is different.
