Reading VA Decision Letters: What 'Deferred,' 'Service-Connected,' and '0% Rating' Actually Mean

A VA decision letter arrives. It's 5-30 pages. It uses formal language, references regulations by code, lists each claimed condition separately, and ends with a rating decision and a back page about appeal rights.

Most veterans read the first paragraph and the rating, then put it away. They don't really know what the rest of the letter says, and they don't read the parts that matter most.

Family members who can read a VA decision letter can spot errors, identify deferred claims, see what evidence was missing, and figure out the right next move. This guide is the field manual.

What a VA decision letter is

A formal document from the VA Regional Office (or BVA on appeals) communicating the outcome of a claim. It's both:

• A decision (granted, denied, deferred, or partially granted, with effective dates and ratings)
• A reasoning record (why the VA decided what it decided)
• A roadmap for next steps (appeal options, what's next on deferred items)

The letter is a legal document. The deadlines and language matter.

Structure of a typical decision letter

Top: the cover letter

Standard VA letterhead. States the date, claim file number, the veteran's name, and a one-paragraph summary of what was decided. This is what most veterans read.

The cover letter is the headline. The actual decision is in the rating decision attachment.

Middle: the Rating Decision

Several pages, broken down by claimed condition. For each condition, the rating decision shows:

• The condition name
• The decision (granted, denied, deferred)
• If granted, the rating percentage and effective date
• The diagnostic code under 38 CFR Part 4 (the rating schedule)
• A "Reasons for Decision" or "Reasons and Bases" section explaining why
• Reference to specific evidence considered

Back: VA Form 21-0998 — Notice of Disagreement / appeal rights

Standard appeal-rights notice. Lists the timelines and pathways for disagreeing with the decision.

Key terms decoded

Service-Connected

The VA has determined the condition is connected to military service. This is the gateway to VA disability compensation. The VA may grant service connection at 0% (recognition without monthly payment) or at a higher rating.

Not Service-Connected (Denied)

The VA decided either the condition doesn't exist, or it isn't connected to service, or both. This is appealable.

Deferred

The VA hasn't made a decision yet on this specific issue. Often happens when:

• Additional evidence is needed
• A C&P exam is being scheduled
• The condition's relationship to service requires more investigation

A deferred claim isn't denied — it's pending. The veteran doesn't need to do anything immediate, but should follow up if the deferral lingers more than 90 days.

0% Rating (Service-Connected, Noncompensable)

The VA recognizes the condition as service-connected but rates it at 0%. No monthly compensation, but:

• The condition is on the record (important for future claims if it worsens)
• Treatment for the condition is covered by VA healthcare
• It can be reopened later if the condition worsens

A 0% rating is not nothing. It's the foundation for future claims if the condition progresses.

10% / 20% / 30% / etc.

The compensable rating levels. Each adds monthly tax-free compensation. Ratings increase in 10% increments up to 100%. The dollar amount per percentage varies based on the veteran's family situation.

Combined Rating

Multiple ratings are combined using the VA's combined rating table — NOT simple addition. Two 50% ratings don't equal 100%; they combine to 75%. The VA uses what's sometimes called "VA math."

The combined rating determines monthly compensation. Family members helping with claims should understand that adding more lower-rated conditions has diminishing returns once the combined rating is high — though there are exceptions for SMC and other special programs.

TDIU (Total Disability based on Individual Unemployability)

A veteran rated at 60% (single condition) or 70% (combined with at least one 40%+) who cannot maintain substantially gainful employment due to service-connected conditions can be paid at the 100% rate via TDIU even if their combined rating is below 100%.

If the decision letter mentions TDIU, this is a critical determination worth understanding fully.

SMC (Special Monthly Compensation)

Additional compensation beyond the standard schedule for veterans with specific severe conditions or combinations: loss of use of limbs, blindness, housebound status, aid and attendance, etc. There are many SMC categories (S, L, M, N, O, P, etc.) with different amounts.

If the letter mentions SMC, the veteran has been recognized for an enhanced compensation tier.

Effective Date

The date from which the rating is paid. Usually the date the claim was filed. Can be earlier in some cases (1-year-back rule for separation-period claims, retroactive based on certain conditions).

The effective date matters enormously. A claim filed 6 months after separation but granted with effective date back to the day after separation can produce a large back payment.

Deferred Issues

A list at the end indicating any conditions that are still pending. The deferred issues will receive their own decision later. Don't assume "no decision" means "denied."

Common errors to look for

Wrong effective date

The VA sometimes uses the wrong effective date — typically the date of the C&P exam rather than the date of the claim. This costs the veteran retroactive compensation. Worth challenging.

Missing conditions

If the veteran filed for 5 conditions and the decision only addresses 4, the 5th may have been overlooked. Check carefully against the original claim.

Misclassified evidence

The "Reasons and Bases" section will reference evidence considered. Sometimes the VA cites the wrong evidence, misinterprets it, or fails to mention key supporting evidence the veteran or family submitted.

Math errors on combined rating

Combined ratings are calculated using a specific table. Miscalculations happen. If the math seems off, double-check using a VA combined rating calculator (free online).

TDIU not considered

If the veteran is at 60%/70% and unable to work, TDIU should be considered. If the decision doesn't address it, the veteran can request a TDIU evaluation.

Wrong diagnostic code

Each condition is rated under a specific diagnostic code in 38 CFR Part 4. Sometimes the VA uses a code that's lower-rating than the appropriate one. A different code can mean a different rating.

Service connection denied based on missing evidence

Sometimes denials cite "lack of evidence" when in fact key evidence was submitted but not considered. Check the evidence list against what was actually filed.

What to do after reading the letter

If the rating is what was expected

• Verify the effective date
• Verify the back-payment calculation
• Confirm CHAMPVA, healthcare priority, and other downstream benefits are updated
• File for any related benefits triggered by the rating (CHAMPVA, etc.)
• Set aside money for any lump-sum back payment

If the rating seems too low

The veteran has options:

1. Higher-Level Review — VA reviews the decision under a different reviewer, no new evidence allowed (must be filed within 1 year)
2. Supplemental Claim — file new and relevant evidence (must be filed within 1 year to preserve effective date)
3. Appeal to Board of Veterans' Appeals (BVA) — full appeal, can include hearing (must be filed within 1 year)

The 1-year deadline is critical. Missing it means starting from scratch with a later effective date.

If a condition was denied

Same three options. Evaluate which approach fits:

• Higher-Level Review: same evidence, different reviewer. Useful when the VA appears to have missed something obvious.
• Supplemental Claim: new evidence (medical opinion, lay statements, etc.). Useful when more evidence can be developed.
• Direct Appeal to BVA: longer process but allows hearings and broader review.

If conditions were deferred

Wait for the eventual decision on the deferred issues. Follow up at 90 days if no movement. The deferred decisions will arrive in a separate letter.

If TDIU should have been considered but wasn't

File VA Form 21-8940 (Veteran's Application for Increased Compensation Based on Unemployability).

Pulling the rating decision apart with the veteran

A useful exercise:

1. Sit down with the letter and a notepad
2. Read each condition's section out loud
3. Note: granted/denied/deferred, rating, effective date, diagnostic code
4. Compare to what was claimed
5. Note any conditions that were missed or that have suspect ratings
6. Compute the combined rating manually if needed
7. Identify the next-move list

This 30-60 minute exercise often surfaces issues the veteran (or family) would have missed in casual reading.

What about the appeal rights notice on the back

The standard form lists three pathways:

• VA Form 20-0995 — Supplemental Claim
• VA Form 20-0996 — Higher-Level Review
• VA Form 10182 — Notice of Disagreement (Appeal to Board)

Each has different rules, evidence allowances, and timelines. The veteran should not pick a pathway alone — a VSO or attorney should advise based on the specifics.

When to get help

A VSO or accredited claims agent can:

• Read the decision and identify issues
• Recommend which appeal pathway fits
• Help gather additional evidence
• File the appeal forms

For complex cases — multiple conditions, denied service connection on subtle grounds, large amounts of money at stake — a fee-based accredited attorney may be appropriate. Attorneys typically work on contingency for VA appeals (capped at 20% of past-due benefits), and don't charge for ongoing benefits.

What to remember

VA decision letters are dense but readable with the right key. Family members who can decode them can:

• Spot errors that cost the veteran money
• Identify deferred items that need follow-up
• Recognize when an appeal is warranted
• Help the veteran understand what was actually decided

The key terms to know: service-connected, not service-connected, deferred, effective date, combined rating, TDIU, SMC. The math is non-intuitive but learnable. The deadlines (especially the 1-year window for appeals) are non-negotiable.

If your veteran has a VA decision letter and hasn't read it carefully, sit down together and walk through it. Often, what looks like a final answer is actually a starting point.
