VA Service Connection Severance Evidence Checklist

A VA service connection severance evidence checklist helps veterans respond when VA proposes to remove service-connected status from a disability. Severance is not just a lower percentage. It means VA is questioning whether the condition should be treated as service connected at all, which can affect compensation, secondary claims, Special Monthly Compensation, and related benefits.

This article is for veterans who received a proposed severance letter, a decision letter raising service-connection error, or a confusing notice that mixes reduction language with service-connection language. TYFYS is a private paid service. We are not the VA, not a VSO, and not a law firm. This is educational evidence strategy, not legal advice. If a deadline-sensitive severance, fraud allegation, character-of-discharge issue, or appeal-rights question is involved, speak with an accredited VSO, claims agent, or attorney quickly.

What VA service connection severance means

Service connection is the VA finding that a disability is linked to military service, a service-connected condition, a presumptive rule, aggravation, toxic exposure, medication effects, or another recognized theory. A rating percentage is the amount of compensation assigned after service connection exists. Severance attacks the first part. Reduction attacks the second part.

That difference changes the evidence task. A proposed rating reduction usually asks whether the disability improved enough to justify a lower percentage. A proposed severance asks whether the service-connected status should be maintained. The file may need service treatment records, military personnel records, nexus evidence, diagnosis history, exposure facts, secondary-service-connection proof, and the original rating basis.

Under section 3.105(d), service connection may be severed only when the evidence establishes that the original grant was clearly and unmistakably erroneous, with the burden on the government. That phrase is a high standard, but this article does not tell you what argument to make. It helps you organize the facts an accredited representative or evidence team would need to review.

The 60-day severance evidence window

When VA considers severance warranted, section 3.105(d) calls for a proposed rating decision with material facts and reasons. The veteran is notified and generally receives 60 days to present additional evidence showing service connection should be maintained. If evidence is not received in that period, VA may issue a final rating action if the record supports it.

Because severance can involve hearing rights, representation rights, appeal rights, and payment consequences, this is one of the claim situations where a veteran should strongly consider accredited help. TYFYS can help with evidence organization and private medical evidence readiness, but we do not represent veterans before VA or choose legal strategy.

The 11-part severance evidence checklist

A severance-response packet should be smaller and cleaner than a full claims file. The point is to answer the proposed severance reason, not to upload every record the veteran owns.

1. Proposed severance letter

Save the full proposal, envelope or notice date if available, and any VA.gov upload or mail deadlines. Highlight the condition, diagnostic code if listed, current percentage, proposed action, exact reason, and whether VA is discussing severance, reduction, or both.

2. Original rating decision and code sheet

Find the decision that first granted service connection. If a code sheet is available, capture the effective date, diagnostic code, secondary or direct theory, static status, and any later changes. The VA rating decision letter checklist can help turn the decision into an issue map.

3. Effective-date calculation

Calculate how long service connection has been in effect. The 10-year protection rule is based on the effective date of service connection and the effective date of the decision severing service connection. Do not confuse this with the date a later increase was granted.

4. Service records and character-of-service facts

If VA says the grant was wrong because of service eligibility, character of discharge, line of duty, deployment, exposure, or an in-service event, gather the exact records that prove the service facts. Useful records can include DD214s, personnel records, service treatment records, orders, deployment records, line-of-duty documents, and unit or exposure records.

5. Current diagnosis and diagnosis history

If VA relies on a changed diagnosis, collect the diagnosis history from the original grant through today. Include C&P exams, private exams, VA treatment notes, specialist records, diagnostic testing, and DBQs. If a later examiner says the original diagnosis was wrong, the file should show whether another diagnosis or residual condition still supports service connection.

6. Nexus or medical-reasoning evidence

A medical opinion can matter when VA says the original grant lacked a valid link to service or a service-connected condition. A useful opinion is specific: it reviews the records, identifies the service event or primary condition, explains the medical pathway, addresses contrary facts, and avoids broad unsupported phrases. Review what a nexus letter should do before relying on a generic note.

7. Secondary-service-connection path

If the original theory is weak, check whether the record supports another path, such as secondary causation, aggravation, medication side effects, altered gait, toxic exposure, or obesity as an intermediate step. This does not mean inventing a new theory. It means reviewing what the record already reasonably raises. Useful internal starting points include the medication side effects checklist and obesity intermediate step checklist.

8. Presumptive or exposure basis

Some service-connection questions turn on a presumptive rule, deployment location, exposure history, chronic disease rule, or toxic exposure risk activity. If VA ignored a presumptive or exposure pathway, assemble service-location records, diagnosis records, onset timeline, exposure notes, and any prior VA findings. The TERA evidence guide can help organize exposure facts.

9. Secondary claims and downstream benefits

List every benefit tied to the condition VA wants to sever: secondary disabilities, SMC, TDIU theory, combined rating, dependents benefits, VA health care issues, or prior medical evidence. Use the TYFYS VA rating calculator to estimate how the combined rating might change, but do not treat calculator math as a legal answer.

10. Lay evidence that fills factual gaps

Lay evidence can help with observable facts: in-service symptoms, continuity, visible symptoms, functional changes, medication effects, exposure details, or how the condition has affected ordinary life. It should not try to become a medical opinion unless the person is qualified. Use the personal statement guide and buddy statement guide for structure.

11. Upload proof and exhibit index

Create a one-page index that names each exhibit and the issue it supports. Example: "Exhibit 4: June 2014 deployment orders - confirms location VA says is missing." Keep upload confirmations, fax receipts, certified-mail tracking, or VA.gov screenshots. The Blue Button records guide and private medical records guide can help gather source documents cleanly.

10-year service-connection protection facts

The most important first-pass protection question is simple: has service connection been in effect for 10 or more years? Section 3.957 protects service connection that has been in effect for 10 or more years, with limited exceptions involving fraud or service/character-of-discharge records.

Question	Where to look	Why it matters
When did service connection begin?	Original rating decision, code sheet, VA benefit letter, C-file.	The 10-year clock starts with the effective date of service connection.
Is VA alleging fraud?	Proposed severance reasons and any investigative language.	Fraud allegations require accredited legal review quickly.
Is VA questioning qualifying service?	DD214, personnel file, service department records, discharge character.	Section 3.957 has a limited exception for service or character-of-discharge records.
Is the issue actually a percentage reduction?	Proposal wording, diagnostic code, current and proposed percentages.	Reduction and severance use different evidence maps.

If the condition is under 10 years, the evidence task is still serious. The veteran may need to show the original grant was not clearly and unmistakably wrong, that another service-connection theory supports the condition, or that VA's diagnosis-change reasoning is incomplete. Those are legal and evidence questions, so do not handle them casually.

Service-connection theories to review

A severance packet should check all plausible service-connection paths raised by the record. This is not the same as filing a new claim. It is a way to avoid defending only one narrow theory when the evidence may support another.

Theory	Evidence to look for	Related TYFYS resource
Direct service connection	Current disability, in-service event/injury/disease, medical link.	Service connection denial guide
Secondary service connection	Primary service-connected condition, current secondary disability, medical pathway.	Medication side effects checklist
Aggravation	Baseline severity, worsening pattern, medical explanation of aggravation.	Nexus letter guide
Presumptive or exposure	Qualifying service location, dates, diagnosis, onset, exposure details.	TERA evidence guide
Continuity or chronicity	Symptom timeline, treatment records, lay observations, early post-service records.	Personal statement guide

Medical evidence that can matter

Medical evidence matters most when the severance theory is diagnosis change, missing nexus, wrong condition label, or unsupported secondary relationship. A strong medical packet usually includes 4 things: the original diagnosis or grant basis, the current diagnosis or residual condition, a record review, and a clear explanation of why service connection can still be maintained.

For mental health claims, diagnosis labels can change over time. For joint, nerve, respiratory, digestive, and headache claims, the diagnosis may evolve as testing improves. The question is not always whether the original label was perfect. The question is whether the veteran has a current disability picture that remains connected to service or to a service-connected condition under a valid theory.

If a private DBQ or medical opinion is being considered, use what a DBQ does and does not do and the private medical evidence guide. The provider should not write a one-sentence conclusion. The file needs reasoned medical analysis tied to records.

Common mistakes

• Treating severance like a normal increase claim. The issue is service-connected status, not only current severity.
• Missing the 60-day evidence window. The proposal period is the time to submit targeted proof and seek accredited advice.
• Ignoring the 10-year effective date. Service-connection protection depends on the effective date, not the date the veteran first noticed symptoms.
• Defending only the original theory. The record may support direct, secondary, aggravation, presumptive, or exposure theories.
• Uploading a document pile. A clean exhibit index is easier to review than 200 pages with no explanation.
• Using lay statements as medical opinions. Lay statements should focus on observable facts unless the writer has medical expertise.
• Waiting for the final decision before reading the file. By then, the strongest pre-decision window may be gone.

How TYFYS fits into the evidence review

TYFYS can help veterans organize records, identify missing evidence, prepare a condition-specific evidence map, and coordinate private medical evidence when the gap is medical clarity. For severance questions, that usually means building a clean file around the proposed reason: diagnosis, nexus, secondary pathway, exposure basis, service records, or current disability facts.

TYFYS does not file VA claims, request hearings, choose appeal lanes, provide legal advice, or represent veterans before VA. Proposed severance can be deadline-sensitive and legally complex. If the issue involves fraud, CUE, service-character dispute, hearing rights, or a final adverse decision, involve an accredited VSO, claims agent, or attorney. If the blocker is evidence organization, start with the TYFYS intake.

FAQ

What is VA severance of service connection?

VA severance means VA removes service-connected status for a disability. It is different from reducing a percentage. Severance can affect the condition itself, compensation, secondary claims, and benefits connected to that disability.

How much time do I have to submit evidence after a proposed severance?

Under section 3.105(d), VA generally gives 60 days to submit evidence showing service connection should be maintained. Read the letter carefully because hearing, response, and appeal rights can involve separate timing issues.

What is the VA 10-year rule for service connection?

Section 3.957 protects service connection that has been in effect for 10 or more years, except limited situations such as fraud or service-character issues. Calculate the 10 years from the effective date of service connection.

Can VA sever service connection after 10 years?

It is much harder after 10 years because section 3.957 adds protection. If VA alleges fraud, lack of qualifying service, or character-of-discharge problems, get accredited representation quickly and gather the source records.

What evidence should I gather for proposed severance?

Start with the proposal letter, original rating decision, code sheet, service records, diagnosis history, medical nexus evidence, secondary or presumptive theory proof, lay evidence for observable facts, and upload confirmation.
