The VA Disability Claim Blueprint

Nexus opinions, secondary conditions, the C&P exam and combined ratings math, explained in one PDF. Education, not representation.

Built from the published VA rating schedule (38 CFR Part 4) and the M21-1 adjudication manual. Educational only: it does not promise any rating or outcome.

The Problem

You served. You filed. And the rating doesn't seem to match the pain you live with every day, the sleep you don't get, or the stack of medical records you have. VA rates against the written criteria in 38 CFR Part 4, not against how hard a condition feels. Learning that language helps you understand your decision and talk with your representative.

What This Guide Delivers

The VA Disability Claim Blueprint explains what a nexus opinion addresses, how secondary service connection works, what the C&P examiner is measuring, and how combined ratings are calculated. It is education to help you prepare for a conversation with an accredited representative (a VSO representative, accredited claims agent or VA-accredited attorney). VSO help is free.

Inside this guide:
  • Sample nexus opinion outlines for common conditions (PTSD, TBI, chronic pain, sleep apnea and hypertension) that show what a medical opinion usually addresses. Your own provider writes any opinion in their own words.
  • A secondary conditions map: 20+ conditions often claimed as secondary under 38 CFR 3.310, organized by primary diagnosis, to discuss with your representative
  • A PACT Act presumptive conditions checklist covering burn pit, contaminated water and radiation exposure, with the regulation behind each presumption
  • A C&P exam prep checklist: what the examiner is measuring and how to describe your condition accurately over time, flare-ups included (38 CFR 4.1)
  • A combined ratings worksheet that walks through the 38 CFR 4.25 table so you understand how VA combines ratings

The C.L.A.I.M. Framework

1
CATALOG YOUR CONDITIONSList every diagnosed condition, physical and mental, and compare it with the secondary conditions map and the PACT Act presumptive list, so you have a complete list to review with your representative.
2
LEARN THE NEXUS STANDARDLearn what a medical nexus opinion addresses and the 'at least as likely as not' standard of proof. No magic words are required: VA weighs the whole opinion and its reasoning, and VA can obtain its own medical opinion (38 CFR 3.159(c)(4)).
3
ASSEMBLE YOUR EVIDENCEUse the evidence checklist to understand the kinds of evidence VA considers: service records, medical records and opinions, buddy statements and your own lay statement.
4
PREPARE FOR YOUR C&P EXAMPrepare for your Compensation & Pension exam using the C&P Prep Script, which walks you through how to accurately describe your symptoms over time, flare-ups included, so the examiner's report reflects how the condition affects you.
5
MASTER THE COMBINED RATINGS MATHUse the combined ratings worksheet to see how 38 CFR 4.25 combines ratings. The table applies in a fixed order, highest rating first, so you can check the math on your decision letter.

Frequently Asked Questions

Do I need a lawyer or VSO to use this guide?

This guide is education about how the rules work. It is not legal advice and it does not prepare or review anyone's claim. For your claim, work with an accredited representative: a VSO representative, accredited claims agent or VA-accredited attorney. VSO help is free.

Will this work if my claim was already denied?

The guide explains the three review options after a decision: a Supplemental Claim (new and relevant evidence), Higher-Level Review, and a Board appeal. Which one fits your decision is a question for your accredited representative.

What did the PACT Act rules add recently?

In January 2025 VA added two presumptive rules for fine particulate matter (burn pit) exposure: 38 CFR 3.320a for bladder, ureter and related genitourinary cancers (90 FR 23, January 2, 2025) and 38 CFR 3.320b for leukemias, multiple myeloma, myelodysplastic syndromes and myelofibrosis (90 FR 1894, January 10, 2025). Ask your accredited representative whether either applies to your service.

Is this guide kept current with VA rules and rating tables?

This edition was written in May 2026 against the rules in force then. Rules change, so check the current regulation on ecfr.gov, or ask your accredited representative, before you rely on any detail.
