What Is a C-File, and How Do You Request It? (Form 20-10206)

If a past claim didn't go the way you expected, or you're not sure why the VA landed on the percentage it did, there's one document that answers the question directly: your own C-file. It's not something most veterans think to request, mostly because nobody tells them it exists until they need it — and by then, it's already a weeks-to-months wait.

What is a C-file?

A C-file, short for claims file, is the VA's complete record of everything it has used to evaluate your disability claims. That includes your service treatment records, any C&P exam reports, medical evidence you or your providers submitted, correspondence between you and the VA, and every rating decision letter you've ever received. If you've filed more than one claim over the years — an original claim, a claim for increase, a secondary condition, an appeal — your C-file is where the full history of all of it lives in one place.

How is a C-file different from my Service Treatment Records?

They're often confused, but they cover different things. Your Service Treatment Records (STRs) are your military medical file — the treatment, diagnoses, and visits documented while you were in service. Your C-file is broader: it includes your STRs, but also everything that's happened since, across your entire relationship with VA disability claims. A one-line note about back pain from a medic during service might live in your STRs; the C&P exam report that rated your back condition twenty years later lives in your C-file.

How do you request your C-file?

You request a copy using VA Form 20-10206, the same way you'd request your STRs and other VA records. Like STRs, C-file requests typically take weeks to months to process — they're not instant the way VA medical records are through Blue Button on My HealtheVet. Because of that lag, the C-file is one of the requests worth firing off early rather than waiting until you think you'll need it.

Who actually uses your C-file?

The person deciding your claim is a Rating Veterans Service Representative, or RVSR — a VA employee whose job is to apply the rating schedule to whatever evidence sits in your C-file. They don't visit you, examine you, or ask follow-up questions; they work from what's already in the file. That's the practical reason the C-file matters so much: the RVSR's decision is only as complete as what made it into the record. If a piece of evidence you submitted, or a detail from an exam, didn't end up in your C-file the way you expected, it also didn't end up in front of the person deciding your percentage.

When is the best time to request it?

The same day you submit an Intent to File. An Intent to File protects your effective date for up to a year while you build your claim — and since your C-file request is one of the slower-moving pieces, starting it on day one means it has the best chance of arriving before you need to reference it, instead of becoming the thing you're still waiting on when everything else is ready.

What can your C-file tell you about a past decision?

If a previous claim was denied or rated lower than expected, your C-file shows exactly what the rater had access to: which exam reports were used, which medical records were considered, and the reasoning behind the decision. That matters because sometimes the gap isn't missing evidence you never gathered — it's evidence that existed but wasn't in front of the rater when the decision was made, or a C&P exam report that didn't reflect what's already documented elsewhere in your history. Reviewing your C-file before you file a Supplemental Claim or request a Higher-Level Review is how you find out which one actually applies to your situation, instead of guessing.

It's also worth comparing your C-file against your rating code sheet — the attachment to your decision letter that lists each condition, its diagnostic code, and your combined rating. If the code sheet references a diagnostic code or an exam finding that doesn't match what's actually documented in your C-file, that's a concrete, specific error to point to, rather than a general feeling that something was rated wrong.

What if a C&P exam missed something already in your file?

It happens: an examiner asks basic questions that your existing records already answer, which can be a sign they didn't review your full file before the exam. If that happens, a formal statement noting exactly what the examiner appears to have missed — with reference to where it's already documented — is worth submitting. Your C-file is what lets you point to the specific record and say, plainly, that it was already there.

Bottom line

A C-file is the VA's record of everything it's used to decide your claims — and requesting one costs nothing but time, which is exactly why the request belongs on your to-do list early, not after a decision has already gone sideways. If you're working through Lima Charlie's A-to-Z Checklist, the C-file request sits right alongside your Intent to File in the very first step, for exactly this reason: it's slow, so it should never be the thing you start last.
