A VA decision letter is long, technical, and arrives on its own timetable. This page walks through the sections in order, explains what each one decides, and flags the deadlines and easy-to-miss details that matter most inside your 1-year appeal window.

What your decision letter actually contains

Most rating-decision packets follow the same order. The packaging varies by regional office, but the building blocks are consistent and each one is required by VA due-process rules[src].

  • Cover / notification of decision. A short letter summarizing the outcome, your new combined rating if it changed, and when payment changes. This is a summary — it is not the full decision.
  • Rating codesheet. The table that lists each condition, the diagnostic code, the percentage assigned, and the effective date. This is the line-item decision.
  • Reasons and Bases narrative. A written explanation for each condition — what evidence VA relied on, which diagnostic criteria it applied, and why it chose the percentage it chose.
  • Effective date block. The date your award begins. This date drives every dollar of back pay.
  • Evidence considered. A list of the records VA reviewed — service treatment records, VA and private medical records, lay statements, and your C&P exam report.
  • What you can do next. Your appeal rights and the three review lanes — Higher-Level Review, Supplemental Claim, or an appeal to the Board of Veterans' Appeals. You have one year from the date on the decision letter to preserve those rights.

Understanding the rating table

The rating codesheet is where the math lives. For each condition you will see a four-digit diagnostic code, a percentage, and an effective date. The diagnostic code points to a specific entry in the VA Schedule for Rating Disabilities (38 CFR Part 4) — that is the rule VA used to pick the percentage.

Your combined rating is not the sum of the individual percentages. VA uses the whole-person formula in 38 CFR § 4.25, which progressively reduces each added condition against what is left of a healthy person. A 50% and a 30% rating do not combine to 80% — they combine to 65%, which rounds to 70%. Our combined-rating estimator reproduces the math line by line so you can check the codesheet against your own numbers.

Effective date — why it matters so much

The effective date is the date your benefits start counting from. It is usually the date you filed, or the date of an earlier intent to file if you submitted one[src]. Every month between your effective date and the decision typically generates back pay at the new rate.

Two patterns are easy to miss. First, a veteran who filed an ITF months before the formal claim may be entitled to an earlier effective date than the letter states — the ITF anchors the clock. Second, veterans who file within a year of discharge may be entitled to a day-after-discharge effective date under § 3.400(b). Our effective-date strategy tool walks through the common anchors, and the retroactive-pay estimator shows what an earlier date may be worth.

Reasons and Bases — where disagreements hide

The Reasons and Bases narrative is the most useful section for choosing an appeal lane. VA is required to explain which evidence it credited, which it rejected, and why — and that explanation usually reveals the single sentence you disagree with.

  • If VA wrote that there was no nexus opinion linking your condition to service, a Supplemental Claim with a new nexus letter from a treating provider may be the right path.
  • If VA got the facts right but applied the rating criteria in a way you disagree with, a Higher-Level Review by a senior reviewer can address a legal or factual error in the same evidence record.
  • If VA did not address all the symptoms you reported — or missed the benefit-of-the-doubt rule in close cases[src] — that is also something a Higher-Level Review or a Board appeal can raise.

Our appeal-path selector compares the three lanes side by side.

Your 1-year appeal window

You have one year from the date on your decision letter to file a Higher-Level Review, a Supplemental Claim, or a Board appeal that preserves your effective date. Miss the window and, in most cases, the decision becomes final — a later Supplemental Claim can still be filed, but the earlier effective date is usually lost.

Narrow exceptions exist. Equitable tolling and clear-and- unmistakable-error claims may revive a late appeal in rare circumstances, but they are fact-specific and hard to win alone. If your window has already closed, talk to a VA-accredited attorney or a VSO before assuming the door is shut.

Common things veterans miss in their letter

  • Inferred TDIU. When the record raises the possibility that service-connected conditions prevent work, VA is expected to consider TDIU[src] even without a separate application. If your letter does not mention TDIU and you cannot sustain full-time work because of rated conditions, that is worth raising.
  • Secondary conditions you did not claim. A service-connected knee can cause a secondary back or hip condition; sleep apnea is often secondary to PTSD or sinusitis. These are separate claims — the decision only rates what you asked for.
  • SMC entitlement. Certain rating combinations trigger SMC automatically (for example, a single 100% plus a separate 60%). If your codesheet looks close to one of those patterns and SMC is not listed, flag it.
  • Earlier effective date arguments. Check the ITF date, your discharge date, and the date your first evidence of the condition reached VA.
  • Evidence not considered.If records arrived after the decision was drafted, the “evidence considered” list will not include them — a Supplemental Claim with that evidence may be appropriate.

What to do next

  1. Write down your 1-year deadline. Use the date printed on the decision letter, not the day you opened the envelope. Put it on a calendar you check.
  2. Compare the decision to your evidence. Lay the codesheet, the Reasons and Bases narrative, and the evidence list next to the records you submitted. Mark anything VA missed or misread.
  3. Call your CVSO or VSO. Accredited representatives have read thousands of these letters and can often spot an inferred claim, an SMC pattern, or an effective- date argument in a single sitting. Most county offices offer same-week appointments at no cost.
