The VA rating decision letter contains the exact basis for every dollar you receive — or don't receive. Most veterans never fully understand what's in it. This guide breaks it down section by section: what each part means, how to identify rating errors, and the exact steps to take when you disagree. You have one year to appeal. Don't waste it.
When the VA makes a rating decision, they send you two documents: a decision notification letter (the shorter cover letter) and the full rating decision document (the detailed analysis). Both arrive together — usually by mail — but many veterans only read the first page, miss critical information in the longer document, and then miss their appeal window. Understanding every section is essential.
The cover letter is a brief summary stating what the VA decided on each claimed condition — service connected or not, and at what percentage. It also states your new combined disability rating and your new monthly payment amount (if applicable). This is what most veterans read and stop at. Do not stop here. The cover letter is just the headline; the rating decision document is the full story.
The first major section of the full rating decision lists every condition you claimed and the VA's decision on each. Each condition will be listed with one of these statuses:
This is the most important section for appealing a decision. For each claimed condition, the VA must explain: (1) what evidence they considered, (2) what they found the facts to be, and (3) why that led to their decision. Under 38 CFR § 19.5 and the Board of Veterans' Appeals regulations, the VA is required to provide an adequate statement of reasons and bases for every decision. If this section is vague ("the evidence does not show..."), that inadequacy may itself be grounds for appeal.
Read every word of the Reasons and Bases section for each denied or under-rated condition. Look for:
Service connection means the VA has officially recognized that your disability is related to your military service. This acknowledgment creates legal rights:
A 0% service-connected condition is still a win — it establishes the connection, and you can file for a rating increase whenever your condition worsens enough to cross the 10% threshold.
Buried in the Reasons and Bases section — often in dense regulatory language — is the specific Diagnostic Code (DC) the VA used to rate your condition and the specific criteria language they applied. This is crucial information because:

Cross-reference it with the published VA Schedule for Rating Disabilities at 38 CFR Part 4 (available free at ecfr.gov) to see the full rating criteria and determine whether your evidence supports a higher rating.
Common errors to look for:
Your effective date is the date from which your benefits start — and it determines your back pay. The VA calculates your back pay as the difference between what you were paid and what you should have been paid, from the effective date to the date of the new rating.
The standard effective date rules under 38 CFR § 3.400 are:
Check the effective date listed on your decision letter. If it's later than the date you filed (or later than your ITF date), this is an error worth challenging in your appeal.
Rating errors fall into several categories. Here's a systematic checklist to review every decision letter:
Look up the DC used in your decision at 38 CFR Part 4. Then ask: does this DC accurately represent my condition? Could a different DC — one specific to my diagnosis rather than the general category — produce a higher rating? Bring this question to a VSO or get free claim help to evaluate.
Read the "Evidence Considered" list. Was your nexus letter listed? Were your private medical records listed? Was your personal statement listed? If evidence you submitted is not listed as "considered," it may not have been reviewed. This is a due process error that supports an appeal.
Verify your effective date against your filing records. If you filed an Intent to File, your effective date should go back to that ITF date — not the date your full claim was submitted.
Count the number of conditions you claimed against the number addressed in the decision. Did the VA address every condition you submitted? If a condition you claimed is simply absent from the decision, the VA failed to adjudicate it — and you need to follow up immediately.
Under 38 CFR § 3.102, when there is an approximate balance of positive and negative evidence, the VA must resolve the doubt in the veteran's favor. If the decision denies a condition by citing "insufficient evidence" but your file contains competing positive evidence, this standard may not have been applied correctly.

Near the end of the decision, you'll find a summary showing how all your individual condition ratings combine to produce your total disability percentage. The VA doesn't simply add percentages — it uses the VA combined ratings table, which applies each additional disability to your remaining ability.
Example: A veteran with 70% PTSD and 30% sleep apnea does not have 100%. The math is: 70% takes 70% of your "whole person"; 30% of the remaining 30% = 9%; combined = 79%, which rounds to 80%.
Verify this math using the VA rating estimator. If the combined rating in your decision is lower than what the math produces, this is a calculation error worth disputing.
Under the Appeals Modernization Act (AMA), you have one year from the date of the rating decision to appeal through any of the three lanes:
Submit new and relevant evidence the VA didn't previously consider. Best when you have additional medical records, a new nexus letter, or DBQ. File VA Form 20-0995.
Request a senior VA rater review the same record for errors in law or fact. Best when the error is in how existing evidence was evaluated. File VA Form 20-0996 at /forms/20-0996/.
Appeal directly to the BVA for a formal review with a Veterans Law Judge. Longest timeline but most thorough review. Best for complex legal or factual issues.
For most veterans, the first step after a denial is either a Supplemental Claim (if you have new evidence to add) or a Higher-Level Review (if the error was in how existing evidence was interpreted). Read the HLR complete guide and the supplemental claim vs. HLR comparison to choose the right path.
If you miss the 1-year appeal window, your decision becomes final. You can still file a new claim for the same condition — but your effective date resets to the new filing date, meaning you lose all back pay entitlement from the original decision date.
If you're approaching the deadline and not sure which lane to use, file a Supplemental Claim immediately to preserve your appeal rights, then consult with a VSO or VA-accredited attorney to determine the best strategy.
If the decision is partially favorable — some conditions granted, some denied — you can accept the favorable portions and appeal only the denied conditions simultaneously.
