Your decision letter is not the finish line
When VA finishes your claim, it sends a decision letter. It is easy to read the first line, see a number or the word denied, and stop. That is a mistake. The letter carries two things that shape everything that comes next: the effective date that controls your money, and a clock on your options if you disagree. This guide focuses on what is verifiable and load-bearing, so you read the letter the way it actually affects your benefits.
We will describe the general shape of a decision letter in plain terms, then spend most of the time on the parts with hard rules: the effective date, your review options, and the one-year window.
The general shape of the letter
In broad terms, a decision letter tells you what VA decided on each condition you claimed, points to the evidence it considered, explains its reasoning, and states the dates that apply. Different letters lay this out differently, and the exact section names and formatting can vary, so use your own letter as the guide rather than a template. The parts below are the ones with rules worth knowing cold.
The effective date, and why to check it first
VA defines the effective date simply: "The effective date is the day you can start getting your disability benefits." That single date decides when your payments begin and how much back pay covers the time before then. If the effective date on your letter looks later than you expected, that is worth understanding, because a wrong effective date directly reduces what you are owed. Back pay flows from that date, so an effective date set even a few months late can mean a meaningful difference in what you receive. Our effective dates and back pay guide walks through the rules that set it.
The rated conditions and their codes
Your letter tells you which conditions VA rated and at what percentage. If your rating sheet shows a diagnostic code, that code is how VA labels the condition on the rating schedule. You do not need to memorize them, but knowing which conditions were rated, and at what percentage, tells you whether VA addressed everything you claimed. To see how conditions and ratings line up, browse our VA ratings and conditions pages.
If you disagree: the one-year window
This is the most important thing in the whole letter. A decision you dislike is usually not the end, but there is a deadline. VA states it directly: "For most VA benefits, you have 1 year from the date on your decision letter to request a Higher-Level Review or a Board Appeal." For most benefits, Higher-Level Review and Board Appeal requests are due within one year, but some benefits have shorter deadlines, so follow the exact deadline stated in your own decision letter. A Supplemental Claim may be filed at any time, although VA recommends filing within one year to maintain continuous-pursuit effective-date protection.
There are three review options. VA lists them as Supplemental Claims, Higher-Level Reviews, and Board Appeals. They are not interchangeable, and picking the right one depends on your situation, especially whether you have new evidence.
| Review option | Core idea | Timing |
|---|---|---|
| Supplemental Claim | Add new and relevant evidence | File any time; VA recommends within 1 year to keep your effective date |
| Higher-Level Review | A more senior reviewer looks at the same record | For most benefits, within 1 year of the date on your decision letter |
| Board Appeal | A Veterans Law Judge reviews your case | For most benefits, within 1 year; 60 days for a contested claim |
A Higher-Level Review considers the existing record with no new evidence. It is generally available within one year after an initial or Supplemental Claim decision, and it is not available for contested claims or after a prior Higher-Level Review or Board decision on the same issue. VA is explicit about protecting your effective date: "You can file a Supplemental Claim at any time, but we recommend that you file within 1 year from the date on your decision letter to keep your effective date." Our review options guide breaks down which lane fits which situation, since a lane that cannot accept your new evidence is the wrong lane.
Why the review lanes are not interchangeable
The three options exist for different problems. A Supplemental Claim is built for new and relevant evidence you did not have before. A Higher-Level Review asks a more senior reviewer to look at the same record, which fits when you believe VA got the existing evidence wrong rather than when you have something new to add. A Board Appeal puts your case in front of a Veterans Law Judge. Because VA recommends filing a Supplemental Claim within one year to keep your effective date, and because Higher-Level Reviews and Board Appeals carry the one-year deadline for most benefits, the calendar and the kind of disagreement you have together point to the right lane. Our review options guide walks through that decision in detail.
Reading order that surfaces problems fast
A practical way to read the letter is to work from the parts with deadlines outward. Check the date on the letter first, because it starts the one-year clock. Check the effective date next, because it controls your pay and back pay. Then confirm every condition you claimed was addressed and rated. If any of those looks wrong, you still have the one-year window to act, and the right review option depends on whether you are adding new evidence or arguing the same record.
A hypothetical example
This is a made-up illustration, not a promise about any real case.
Alicia is a hypothetical veteran whose letter grants one condition but denies another and assigns an effective date months later than she expected. Reading in deadline order, she notes the date on the letter, which starts her one-year clock. She sees the effective date and believes it should be earlier. Because she has a new medical opinion for the denied condition, a Supplemental Claim fits that piece, and she plans to file within one year to keep her effective date protected. None of this required her to guess; the letter told her the decision, and the rules told her the deadline.
What this does not mean
A denial is not automatically final. For most VA benefits you have 1 year from the date on your decision letter to request a Higher-Level Review or a Board Appeal, and you can file a Supplemental Claim at any time. Missing that one-year window is what makes a decision hard to move, so the deadline, not the word denied, is the thing to watch.
The official VA pathway
Read VA's decision reviews and effective-date pages, linked in the citations, and note the date on your own letter so you know exactly when the one-year clock ends.
