What is a DBQ?
A DBQ (Disability Benefits Questionnaire) is a standardized VA form a medical provider fills out to document a condition's symptoms, severity, and how it limits your daily function. DBQs are condition-specific — there's a separate template for back conditions, PTSD, sleep apnea, hearing loss, migraines, and dozens of other conditions, each asking the exact clinical questions VA raters need to apply the rating schedule for that condition.
Note: if you landed here researching "DBQ" for a history class, that's a different meaning — "Document-Based Question" is an AP US History essay format, unrelated to VA disability claims. This guide covers the VA's Disability Benefits Questionnaire only.
Who fills out a DBQ
A DBQ can be completed one of two ways:
- By a VA examiner at a scheduled C&P (Compensation & Pension) exam — the VA schedules this exam as part of processing your claim.
- By your own private treating physician, using the same official VA form template, and submitted directly with your claim.
A private DBQ can be a useful option if your own doctor already knows your condition well and can document it thoroughly — it can be submitted alongside your claim instead of, or in addition to, waiting for a scheduled C&P exam.
Where the DBQ form comes from
The VA publishes the official DBQ templates directly on VA.gov, organized by condition. There isn't a private or invented version — whichever provider completes it, VA examiner or private doctor, should use the current official form for that specific condition.
What a DBQ does and doesn't do
A DBQ documents clinical findings — range of motion, frequency of symptoms, functional limitations, and similar measurable facts specific to the condition. It does not itself assign a disability percentage. A VA rater takes what the DBQ (and any other evidence in your file) shows and applies the criteria in 38 CFR Part 4, the VA's rating schedule, to arrive at a percentage. See our VA disability rating calculator once you know your ratings to estimate your combined percentage.
DBQ vs. nexus letter
These two documents are often confused but serve different purposes:
| Document | What it establishes |
|---|---|
| DBQ | Current symptoms, severity, and functional impact of a diagnosed condition |
| Nexus letter | A medical opinion linking the condition to your military service |
Many claims need both: a DBQ to document how severe the condition is today, and a nexus letter to connect it back to your time in service, especially for secondary conditions.
What to do next
If you're preparing evidence for a claim, review our C&P exam tips and nexus letter guide alongside this page — a strong claim typically pairs a thorough DBQ with a clear nexus opinion where one is needed.

Frequently asked questions about DBQs
What is a DBQ? A standardized VA form documenting a condition's symptoms and severity, condition-specific, published on VA.gov.
Who fills it out? A VA C&P examiner, or your own private doctor.
Does it set my rating? No — it documents findings; the rater applies 38 CFR Part 4 to determine the percentage.
DBQ vs. nexus letter? A DBQ documents severity; a nexus letter links the condition to your service.
DBQ by Condition: What's Different on Each Form
Every condition has its own DBQ template, and each one asks different clinical questions because VA rating criteria differ by body system. Here's what the most-searched DBQs actually cover.
Knee DBQ
The knee DBQ records range of motion in degrees (flexion and extension), both before and after repeated movement, plus stability testing for the ligaments. It also asks whether pain, weakness, or swelling further limits motion during flare-ups — this "pain on repeated use" detail matters because two veterans with the same X-ray can get different ratings depending on how much function they've actually lost.
Mental Health / PTSD DBQ
The PTSD DBQ walks through the diagnostic criteria for PTSD, then asks the examiner to check off which specific symptoms apply — things like intrusive memories, avoidance, sleep problems, concentration issues, and irritability. It also asks the examiner to select an "occupational and social impairment" level, which is the main factor that drives your percentage under the mental health rating formula.
Back (Spine) DBQ
The back DBQ records range of motion for forward flexion and extension, side bending, and rotation, along with whether you have muscle spasm, guarding, or abnormal spine contour. It also documents any radiculopathy (nerve pain radiating into the legs) separately, since nerve symptoms from a back condition can be rated in addition to the spine itself.
Hearing Loss DBQ
The hearing loss DBQ is built entirely around a controlled audiogram — pure tone thresholds at several frequencies in each ear, plus a speech discrimination score. Unlike most DBQs, there's little room for the examiner's subjective judgment here: your rating comes almost directly from the test numbers plugged into the VA's hearing loss rating table.
