How to read a VA decision letter, section by section

Twenty-two forms. A thousand acronyms. The VA speaks in static, and a decision letter is the densest static it produces: several pages of regulation citations, exam summaries and boilerplate wrapped around the one or two sentences that actually tell you what happened.

Most veterans read it once for the number and stop. That skips the part that tells you what to do next.

What a VA decision letter actually contains

Every decision letter follows roughly the same shape, whether it runs three pages or thirty:

1. An introduction naming the issues decided and the date of the letter.
2. A code sheet: one line per condition, its diagnostic code, its percentage, and an effective date, ending in a single combined rating.
3. Reasons for Decision: a paragraph per condition explaining what the VA looked at and why it decided the way it did.
4. Evidence: the list of records, exams and statements the rater actually considered.

You can download the letter itself, along with your full claim file correspondence, from VA.gov's claim letters page. The code sheet and the reasons paragraphs are where the real information lives; the rest is regulation text that repeats across every letter the VA sends.

Granted, denied, continued, deferred: four words, four different letters

The single most useful thing to know before reading the reasons section is which of four outcomes you are looking at, because each one calls for a different response.

Deferred is the one letters explain worst, because it is not really a decision at all. What a deferred VA claim means covers that word on its own, including the internal 30-day evidence window most letters never mention by name.

Reading the Reasons for Decision section

This is the paragraph most people skim past to get to the percentage, and it is the one paragraph that tells you why you got that percentage, or why you got nothing.

For a denial, the language usually falls into one of four buckets:

No nexus. Phrases like "not caused by or a result of" or "less likely than not related to service" mean the medical evidence did not connect the condition to your service, or to an already service-connected condition. What service connection actually requires breaks down the three elements a nexus has to satisfy, and what a nexus letter is covers the document built to close that specific gap.

No current diagnosis. The file did not show a diagnosed condition at the time of the claim, only symptoms or a history.

No in-service event. Service treatment records did not document whatever happened in service that the claim rests on.

A missed exam. "Failed to report for examination" means the C&P exam did not happen, and the VA decided on the record it had without it.

The reason is the whole point of reading this section closely, because it tells you exactly what evidence would change the answer. A denial for no current diagnosis needs a diagnosis. A denial for no in-service event needs a record or a statement placing the event in service. Treating every denial the same way, or not reading past the word "denied," means missing which of those four very different problems you actually have.

For granted or continued conditions, this section still matters: it often contains favorable findings, evidence the rater weighed in your favor, that carries forward if the condition ever needs to be reviewed again.

Finding the reason is the hard part

None of this is hidden. It is all in the letter you already have. The problem is that a rater writes for a rater, not for the person reading it at 11pm trying to figure out what to do next, and a multi-issue claim can run the reasons for one denied condition across a page of citations for three others.

That is the specific problem the Decision Letter Decoder exists for. You paste the letter in, and it separates each condition out with its decision, its percentage, and the reason behind it in plain language, entirely in your browser. Nothing about the letter is sent anywhere; it never leaves your device. Reading it yourself is entirely possible with what is already in the document. This just skips the page of citations standing between you and the sentence that matters.

Where the effective date lives, and why it is not the letter date

The effective date sits next to the percentage for each granted or increased condition, and it decides how far back your payment reaches. Under 38 CFR 3.400, it is set to the date the VA received your claim, or the date entitlement arose, whichever is later. That is a different date from the one printed at the top of the letter, which only marks when the decision was written.

This is the mechanism an Intent to File protects: filing one locks a claim date up to a year before the formal claim goes in, so the effective date on a later grant can reach back to it. If the arithmetic of what that is worth in back pay is what you are actually trying to work out, how VA back pay works has it.

Checking the combined rating on the code sheet

The code sheet ends in one number: your combined evaluation for compensation purposes. It is not the sum of the individual percentages. The VA applies the combined ratings table in a fixed order, largest percentage first, which is why two conditions at 50% each combine to 75%, not 100%. The VA math behind combined ratings walks through exactly how that table works.

Recomputing the table yourself and comparing it to the letter's stated combined rating is the only real check against an arithmetic error at the code-sheet stage. A mismatch there is worth a second look. It is not grounds to assume the VA owes you anything, only a reason to read that one line again before deciding whether it is worth raising.

What a denial reason means for your next move

Once you know which of the four denial reasons you got, the review lane question gets easier. A denial for missing evidence, whether that is a diagnosis, a nexus opinion or a service record, is commonly answered by gathering that specific evidence and filing a Supplemental Claim. VA claim denied: your three review lanes compares that lane against a Higher-Level Review and a Board appeal, and which one fits depends on whether you have new evidence or think the rater made an error on what was already there.

None of this requires guessing. The letter states the reason; the reason points at the evidence; the evidence points at the lane. The part that takes the time is reading closely enough to see the chain.

The bottom line

A VA decision letter is not one verdict, it is a code sheet, a set of individual decisions, and a paragraph of reasons behind each one. Granted, denied, continued and deferred are four different situations wearing similar-looking paragraphs, and the reasons section is where the letter tells you, in its own dense way, exactly what would change the outcome.

Reading it once for the percentage and putting it away skips that part. Reading the reasons section for every issue, not just the ones that went your way, is the five extra minutes that turns a letter into a plan.
