The short answer: start with the decision you are challenging, not page one. Read the most recent rating decision and code sheet, then the exams and opinions VA relied on, then VA's own records-request trail, and only then the service and treatment records, targeted to the issues on the table. That order tells you within the first hour what VA found, what it relied on, and where the file is thin, so the rest of the review has a purpose.
A claims file for a long-running case can run to thousands of pages. Reading it front to back puts the least useful material first: years of correspondence, duplicate records, and forms. The order below is built around the questions every case eventually has to answer: what VA decided, why, on what evidence, and what it missed.
Before you open it: the right file, and the right authority
Make sure your power of attorney is recorded first. Accredited agents and attorneys are appointed on VA Form 21-22a; a recognized organization is appointed on VA Form 21-22. Until VA has the appointment on file, it will not share the record with you or send you copies of its notices.
Then get the complete record, not a partial one:
- If you have VBMS access as a representative, work from the eFolder, which shows each document's type and the date VA received it.
- Otherwise, the veteran can request a copy of the claims file with VA Form 20-10206 (the Freedom of Information Act or Privacy Act request). See how to request a C-file.
Note the date of the copy. A file pulled before VA added new records is not the file the next adjudicator will read.
The order that saves hours
- 1The most recent decision. Read the rating decision narrative, its evidence list, and the reasons for each issue, then the code sheet: diagnostic codes, percentages, effective dates, and the combined rating. Write down every finding in the veteran's favor. Under 38 C.F.R. § 3.104(c), a favorable finding binds later VA and Board adjudicators unless it is rebutted by evidence showing clear and unmistakable error, so it is ground you do not have to win again.
- 2The claim and its date. Find the claim form and any intent to file. Under § 3.155(b), a complete claim received within one year of an intent to file is treated as filed on the intent-to-file date. Effective date problems often start here.
- 3The exams and medical opinions. Read every C&P examination and opinion for the issues on the table. Ask of each one: did the examiner review the records, answer the question VA asked, give a rationale, consider the veteran's own account, and, for a secondary claim, address aggravation as well as causation?
- 4VA's records trail. Find each records request VA sent and each response. Did VA request the private records the veteran identified, and follow up? Did it keep requesting federal records until they were obtained or shown not to exist? Did it tell the veteran when it could not get something? These are the duty-to-assist questions in 38 C.F.R. § 3.159(c) and (e). See duty to assist errors.
- 5Service treatment records, targeted. The entrance examination (anything not noted there is presumed sound under § 3.304(b)), sick-call entries for each claimed condition, profiles, and the separation examination and report of medical history.
- 6Personnel records. The DD-214, job, deployments, and duty locations. These decide presumptions (location-based exposure, combat) and support the in-service event for direct claims.
- 7Treatment records after service, VA and private, read issue by issue and in date order. You are looking for onset, continuity, severity at the time of each exam, and findings the rating decision never mentioned.
- 8Earlier decisions. What was decided before, whether it became final, and what evidence was in the file at the time. This is where effective-date arguments and potential clear and unmistakable error live.
What to write down as you go
Keep one line per issue. It becomes the plan for the case and the outline of anything you file.
| Issue and code | Where it stands | What the record shows |
|---|---|---|
| Condition, diagnostic code | Current percentage and effective date | Page references for the best evidence for and against |
| Exam relied on | Date and examiner type | The defect, if any: no rationale, wrong question, lay evidence ignored |
| Next step | Lane you are leaning toward | What new evidence would change the outcome |
Cite pages as you go. A finding without a page reference has to be found again later, usually under a deadline.
Defects worth the time to find
- An opinion with no reasoning. A conclusion without a rationale is the most common weakness in a negative opinion, and it matters in every lane.
- A secondary opinion that stops at causation. Section 3.310 covers conditions caused by a service-connected disability and conditions it made worse. An opinion that never addresses aggravation has answered half the question.
- Lay evidence that was never weighed. A buddy statement or the veteran's own account in the file that neither the examiner nor the decision mentions.
- Service department records added after the first decision. Under § 3.156(c), if VA later receives relevant official service department records that existed and were not in the file when it first decided the claim, VA will reconsider the claim, and an award based on them can reach back to the original claim date.
- Records VA was told about and never requested, or requested once with no follow-up.
- Separately ratable findings left out. Neurologic findings on a spine exam are rated separately from the spine. A knee can carry separate ratings for limited bending, limited straightening, and instability when each is shown.
- Effective dates that ignore an intent to file or a continuously pursued earlier claim.
Working a very large file
- Work the index, not the pages. Sort by document type and receipt date first; most of a large file is correspondence and duplicates.
- Find the duplicates early. The same treatment records are often uploaded several times by different sources.
- Read exams against the records they relied on. An exam that says "records reviewed" and then misstates a date is worth noting with both page references.
- Separate what VA had at each decision. For effective dates, finality, and clear and unmistakable error, what matters is the evidence in the file when each decision was made, which the eFolder receipt dates let you reconstruct.
Once the review is done, the choice of lane usually makes itself: an error on the existing record points one way, missing evidence another. See choosing between a supplemental claim, higher-level review, and a Board appeal.
Frequently asked questions
What should I read first in a VA claims file?
The most recent rating decision and its code sheet. They tell you what VA decided, what it relied on, and the effective dates, which frames everything else you read.
How does a representative get a veteran's C-file?
After VA records the power of attorney (VA Form 21-22a for agents and attorneys, 21-22 for a recognized organization), a representative with VBMS access can work from the eFolder. Otherwise the veteran can request a copy with VA Form 20-10206.
Are favorable findings in a VA decision binding?
Yes. Under 38 C.F.R. § 3.104(c), a finding favorable to the claimant binds later VA and Board adjudicators unless evidence shows clear and unmistakable error in it. Log them so they are not argued again.
What is a 38 C.F.R. § 3.156(c) reconsideration?
If VA receives relevant official service department records that existed but were not in the file when it first decided the claim, VA reconsiders the claim. An award based on those records can be effective as of the original claim date, or when entitlement arose if later.
What are the most common defects in a C&P exam?
No rationale, an answer to a different question than VA asked, the veteran's own account or buddy statements ignored, and, in secondary claims, no answer on aggravation.
