6 of 6 conditions
Lumbosacral or Cervical Strain
A strain or sprain of the muscles and ligaments supporting the neck or lower back, causing pain, stiffness, and reduced range of motion — often from lifting, impact, or repetitive strain during service.
Read the condition guidePreview the guide
Evidence covered in the guide
- C&P or orthopedic exam showing measured loss of range of motion, muscle spasm, or guarding
- Service treatment records documenting the in-service injury, incident, or repetitive strain
- Buddy statements or personnel records corroborating the in-service event (e.g., heavy lifting, vehicle accident, parachute jumps)
Degenerative Arthritis of the Spine
Wear and tear in the spine causing stiffness, pain, or nerve issues.

Evidence covered in the guide
- Range of motion tests from VA or ortho
- MRI or X-ray showing degenerative disc disease
- Doctor notes on back pain frequency
Knee, Other Impairment of
This diagnostic code covers knee instability — the knee buckling, giving out, or shifting out of place — separately from pain or arthritis. Since the 2021 rewrite it rates two named things: recurrent subluxation or instability after a ligament sprain or tear, and instability of the kneecap (the patellofemoral complex) after surgical repair. The tier you land on depends less on how bad the instability feels than on what a medical provider has prescribed for it — a brace, a walking aid, both, or neither.

Evidence covered in the guide
- The prescription itself — the note or order from a medical provider prescribing a brace, cane, crutches, or a walker for walking. Since 2021 this is the single fact that separates the three tiers, and buying a brace over the counter is not the same thing.
- An orthopedic evaluation documenting persistent instability with stability testing (Lachman, anterior drawer, pivot shift), and stating whether a ligament tear is complete or incomplete.
- Operative reports where a ligament or the patellofemoral complex was repaired, plus follow-up notes on whether the repair held — a failed repair rates higher than a successful one on the same prescription.
Degenerative Arthritis
Degenerative arthritis (osteoarthritis) is the gradual breakdown of the cartilage that cushions a joint, producing pain, stiffness, swelling and reduced motion. DC 5003 is not primarily a ladder of its own: the schedule rates degenerative arthritis established by X-ray "on the basis of limitation of motion under the appropriate diagnostic codes for the specific joint or joints involved", so most evaluations come from the affected joint's own code and DC 5003 supplies a floor.

Evidence covered in the guide
- X-rays or an MRI confirming joint degeneration in each affected joint - this is the evidence the rating schedule is built around.
- A doctor's notes describing joint pain, swelling, and specific functional limitations, not just general 'joint pain,' in both your own words and your provider's clinical observations.
- Documentation of any incapacitating episodes or flare-ups, since these are what can raise a claim from the 10% to the 20% tier.
Migraine
Severe recurring headaches that may include nausea, light sensitivity, and inability to function.
Read the condition guidePreview the guide
Evidence covered in the guide
- Neurology consult with detailed migraine history
- Headache diary showing frequency and impact
- Employer or family statements about missed work or functional episodes
Post-Traumatic Stress Disorder (PTSD)
PTSD is a mental health issue caused by a traumatic event, leading to flashbacks, anxiety, or nightmares.
Read the condition guidePreview the guide
Evidence covered in the guide
- Formal PTSD diagnosis from a VA or private psychiatrist
- C&P exam results showing PTSD symptoms
- Buddy statements confirming trauma or symptoms

A FEW HELPFUL ANSWERS
Questions about the 3E3X1 guide
What do the conditions in this guide represent?
They are conditions grouped with 3E3X1 (Structural) by the role’s occupational exposures and physical demands. Use them as a starting point for research. The list does not rank conditions by claim frequency or VA approval rates.
Where can I find rating levels and evidence guidance?
Open a condition preview for a quick look, or follow its guide link for the published rating criteria, an evidence checklist, and available exam guidance.
What if I served in more than one role?
You can explore a guide for each of your military jobs. Use the military job directory to search another code, job title, or branch, and keep notes on the experiences you want to discuss.
What if my condition is not listed here?
This is a curated starting point. The condition library has additional guides you can search by name, body system, or diagnostic code.
