VA C-file Workup Checklist

A C-file workup converts a raw claims file into a structured case record that a reviewing attorney can work from directly. Done right, it surfaces every evidence gap, exam deficiency, and rating theory issue before the claim reaches a rater. Done poorly, it just confirms the file exists.

How to Request the Complete C-file

Start with VA Form 20-10206^[1]. That is the official mechanism for requesting a veteran's claims file, C&P exam records, DD Form 214, and other Privacy Act records. You can submit the form online through VA.gov or mail it to the VA Records Management Center.

Before any workup begins, confirm the file is complete. A truncated record is the most common cause of missed evidence. Check for:

• A DD Form 214 or equivalent separation document for each period of service
• Service treatment records (STRs) covering the full service period, not just one era or branch
• All prior rating decisions, including decisions on conditions not currently claimed
• VA treatment records from all relevant VA facilities
• Any previously submitted private medical records

If STRs are missing or thin relative to the service period, that is not necessarily a gap the veteran created. VA has a duty to assist in obtaining service records, other active duty records, and federal agency records for substantially complete claims. 38 CFR § 3.159^[2] That duty has limits. Once VA issues notice of a decision, the evidentiary record closes. 38 CFR Part 3 Subpart A^[3] Flag record gaps at intake, not after a denial.

Document Segmentation

Before reviewing any document for content, divide the file into categories. Mixing document types during a first pass guarantees missed items and inconsistent review. For a detailed breakdown of what each category establishes and which gaps to flag before attorney review, including how staff roles in segmentation differ from attorney judgment calls, see the document segmentation guide. Segmentation is also the prerequisite for building a chronological timeline from those segments, which surfaces effective date arguments and duty-to-assist failures that condition mapping alone will not catch.

Standard segments:

• Service treatment records. All medical entries from active duty, Reserve, or National Guard service, including sick call, inpatient, and separation physical records.
• Rating decisions. Every decision, including rating code sheets, explanation of benefit determinations, and prior claim decisions. These show what has already been decided and at what percentages.
• C&P exam reports. All examination reports, including DBQs and older-format exam summaries. Each exam should be associated with the specific issue it was ordered to address.
• Private medical records. Records submitted by the veteran or obtained through an authorization. Note the source and date range for each set.
• Federal agency records. Social Security Administration records, treatment records from other federal facilities, and military personnel records beyond the DD Form 214.
• Correspondence. VA letters, rating notifications, VA Form 21-0781 statements, lay statements, and any other correspondence in the file.

Segmentation is not just an organizational preference. Chronology work and condition mapping both require clean source separation. A C&P exam report mixed into the STR segment will skew your event timeline. For a detailed breakdown of what to extract from that STR segment and how to map in-service events to claimed conditions, including chronicity markers, missing record audits, and substitute evidence strategy, see the STR review guide.

Building the Service Chronology

The service chronology is the factual foundation for every nexus analysis in the file. It answers one question: what happened to this veteran, medically, during service?

Pull from STRs only for this step. Extract:

• All documented injuries, illnesses, and complaints in date order
• Diagnoses made during service, including any that were later dismissed or treated as resolved
• Hospitalizations, surgeries, and referrals
• The entrance physical and separation physical, compared for any changes

Note what is absent as well. A condition claimed as in-service origin that has no STR documentation is a nexus theory problem, not just a records problem. That is a different issue than missing records, and the workup should distinguish between the two.

The separation physical is often the most useful single document. Changes between the entrance and separation exams show what the service period did. Conditions noted at separation but not treated as ratable at the time are a consistent source of secondary or direct service connection claims that firms underwork.

Mapping Claimed Conditions to the Rating Criteria

Each claimed condition needs three things: a current diagnosis, an in-service event or injury, and a nexus linking the two. The workup confirms whether the record supports all three for every condition on the claim. VA.gov FDC Evidence Checklist^[4]

For current diagnosis, check whether the record contains a diagnosis that matches what was claimed and whether that diagnosis comes from a competent medical source. VA adjudicators review diagnoses for adequacy before proceeding. M21-1 Part V Subpart ii Chapter 3 Section C^[5] A diagnosis from a lay statement alone is not sufficient. A diagnosis in a private treatment note from a treating physician generally is.

For rating criteria, map each diagnosis to its corresponding diagnostic code in the Schedule for Rating Disabilities. 38 CFR Part 4 (WARMS)^[6] The workup should confirm:

• Which diagnostic code applies
• What the rating criteria require at each percentage level
• Whether the record contains findings that meet any specific rating level
• Whether any conditions overlap in a way that raises pyramiding concerns under 38 CFR § 4.14

Firms that skip the diagnostic code mapping at workup stage push that analysis to attorney review, which is slower and more expensive. A trained paralegal can do this mapping accurately with the right reference materials.

Secondary Conditions

Secondary service connection claims require the same three-element check, plus a link from the secondary condition to the already-service-connected primary condition. The workup should note any condition in the record that is documented as caused or aggravated by a service-connected disability and flag it for nexus development even if it has not been explicitly claimed.

Evaluating C&P Exam Adequacy

A C&P exam is adequate only if it gives the rater the findings and rationale needed to decide the issue on the merits. The exam must address the specific theory being claimed, the relevant rating criteria, and the evidence already in the record. M21-1 Part IV Subpart i Chapter 3 Section A^[7]

For each C&P exam report in the file, check:

• Does the examiner identify the condition under review and the theory of service connection?
• Does the opinion include a rationale, not just a conclusion?
• Does the examiner address the evidence in the record, including STRs and private treatment notes?
• Does the report cover all rating-relevant symptoms, not just the presenting complaint?
• If the exam was negative or unfavorable, does the rationale address the veteran's documented in-service history?

An exam that says "no nexus" without addressing the STR documentation is not adequate. An exam that addresses only current symptoms without rating-relevant severity findings does not support a rating decision. Both are grounds for requesting a new or supplemental examination.

Document each inadequacy specifically. "The exam report does not address the 2003 inpatient knee treatment noted in the STRs" is useful to a reviewing attorney. "The exam seems incomplete" is not.

The M21-1 also sets sufficiency criteria for specific disability types, including musculoskeletal, mental health, and TBI claims. M21-1 Table of Contents^[8] The general criteria in Part IV, Subpart i, Chapter 3 apply across the board. Condition-specific criteria apply on top of those.

Identifying Evidence Gaps and Duty-to-Assist Triggers

VA's duty to assist requires the agency to make reasonable efforts to obtain records that are relevant to the claim and exist in a federal system. 38 CFR § 3.159^[2] That includes service records, VA treatment records, and records held by other federal agencies such as SSA.

The workup should flag:

• STR gaps for any period of service not covered in the file
• Missing VA treatment records where the veteran has documented treatment at a VA facility not in the file
• SSA records where the veteran has claimed disability or received benefits for a condition that overlaps with the VA claim
• Private records identified in the veteran's statements or in existing medical records as existing but not in the file

Each gap should be documented with the source that indicates the records exist and the approximate date range. The duty to assist is not unlimited, but VA cannot be held to have fulfilled it if the firm's workup did not flag what was missing before the evidentiary record closed.

The evidentiary record closes when VA issues notice of a decision. After that point, new evidence can only be submitted through a Supplemental Claim or an appeal lane. 38 CFR Part 3 Subpart A^[3] Gaps found after a denial are recoverable. Gaps found after a one-year appeal window has closed often are not.

Presumptive Service Connection and Special Theories

Some conditions do not require a nexus opinion if the veteran served in a qualifying location or time period and the condition is on the presumptive list. The workup should identify whether any claimed condition qualifies for a presumptive theory before assuming a nexus opinion is required.

Presumptive service connection under 38 CFR § 3.307 covers chronic diseases listed in 38 CFR § 3.309 that manifest to a compensable degree within applicable time limits after separation. 38 CFR Part 3 (WARMS)^[9] For conditions on that list, the workup needs to confirm the qualifying service period and the manifestation date, not a nexus opinion.

The PACT Act expanded presumptive eligibility for veterans exposed to burn pits, Agent Orange, and other toxic substances. For claims with covered service periods and covered diagnoses, the workup should document the qualifying service location and the diagnosis, and flag the presumptive theory explicitly so the reviewing attorney does not send the file out for an unnecessary nexus opinion.

Additional special theories to flag during workup:

• In-service aggravation. Where a pre-existing condition is documented at entrance and the record shows worsening beyond natural progression during service.
• Radiation exposure. Specific diseases and specific service at nuclear test sites or other qualifying locations under 38 CFR § 3.309(d).
• POW status. Former prisoners of war have separate presumptive disease lists under 38 CFR § 3.309(c).
• Individual Unemployability (IU). Where the veteran's service-connected disabilities prevent substantially gainful employment, the workup should confirm the single-disability or combined-disability thresholds under 38 CFR § 4.16. 38 CFR § 4.16 (WARMS)^[10]

Documenting the Workup for Attorney Review

The workup output needs to be structured so a reviewing attorney can verify your conclusions without re-reading the file. A narrative summary of what is in the file is not enough. Every finding needs page citations that tie it to an exact file page, because a citation-free summary cannot be verified, cannot survive a Board challenge, and cannot support a CAVC brief.

Structure the output around conditions, not documents. For each claimed condition:

• State the diagnosis and its source (document, date, provider)
• Map it to the applicable diagnostic code
• Summarize the in-service evidence supporting the nexus theory
• Identify which C&P exam addressed it, whether that exam is adequate, and if not, why not
• List any missing records relevant to that condition
• Flag whether a presumptive or special theory applies

Separate the evidence gaps section. List each missing record category, the source that indicates it exists, and the action needed to obtain it before the evidentiary record closes.

Flag anything that needs attorney-level analysis: conflicting diagnoses, exam reports with mixed findings, conditions that were denied in a prior rating decision, and conditions that may require a nexus opinion from a private examiner.

A workup that organizes findings by document type makes the reviewing attorney do the condition-mapping work all over again. A workup organized by condition with supporting citations gets the file into attorney review ready to act on.
