If your neck or lower back constantly aches and feels stiff after military service, a doctor may note that you have Degenerative Disc Disease (DDD).
Despite the name, DDD is not an infectious illness or a disease you catch from someone else. It is a physical wear-and-tear condition. It means the soft, rubbery cushions in your spine are slowly breaking down and flattening over time.
For military veterans, degenerative disc changes are very common. Active duty demands a lot from your body. Carrying heavy body armor, rucking, jumping from vehicles, and riding in tactical trucks can cause the spine to experience wear and tear years faster than a civilian spine.
Current VA Ratings for Degenerative Disc Disease at a Glance
According to the official VA Schedule for Rating Disabilities (38 CFR § 4.71a), a potential rating for spinal conditions is primarily determined by how much your spine can move before pain limits the motion.
| Rating | Typical Criteria |
| 10% | Mild limitation of motion; or pain, stiffness, and tenderness that does not change how you walk. |
| 20% | Moderate limitation of motion; or muscle spasms/guarding severe enough to cause an abnormal gait or abnormal spinal contour. |
| 30% | Severe neck limitation; or the neck bones are completely frozen in a straight position. |
| 40% | Severe lumbar limitation; or the lower back bones are completely frozen in a straight position. |
| 50% | Unfavorable thoracolumbar ankylosis (the entire lower back is permanently frozen in a bent position). |
| 100% | Entire spine unfavorably ankylosed (both the neck and back are completely frozen together). |
Quick-Reference Spine Diagnostic Codes

What Is Degenerative Disc Disease?
Your spine is a column of bones. The hard bones are called vertebrae. Between each bone sits a soft, rubbery cushion called an intervertebral disc. These discs act like heavy-duty shock absorbers.
They allow you to bend, run, twist, and carry heavy gear without your backbones grinding against each other. Healthy discs contain a high percentage of water, which makes them bouncy.
Degenerative disc disease happens when these cushions dry out and flatten. When a veteran develops DDD, two main physical changes typically occur:
- Loss of Fluid (Drying Out): Years of hard physical demands can cause micro-damage to your discs. They lose their water content, which reduces their natural shock-absorbing capability.
- Cracking and Flattening: Without fluid, the outer shell of the disc can develop tiny cracks or tears. The weight of your body flattens the disc, narrowing the space between your vertebrae.
Common Symptoms of Degenerative Disc Disease in Veterans
The symptoms of DDD can vary significantly from person to person. Some individuals show severe disc wear on an MRI but do not experience high levels of pain. Others may show minor wear on a scan but suffer from daily, lifestyle-limiting discomfort.
Whether you are seeking a lumbar DDD VA rating (lower back) or a cervical DDD VA rating (neck), common symptoms include:
- Chronic Back or Neck Pain: A deep, dull ache in your spine that never truly goes away.
- Pain Worse When Bending or Twisting: Pain that flares up when you move, lift items, or turn your body
- Morning Stiffness: Feeling rigid when you first get out of bed, often requiring movement or heat before the muscles relax.
- Muscle Spasms: Involuntary tightening and hard knots in your back muscles as your body attempts to protect the damaged spinal structure.
Degenerative Disc Disease vs. Herniated Disc
Veterans often confuse Degenerative Disc Disease with a herniated disc. They both can cause severe back and nerve pain, but they are two different problems.
However, they are closely related; long-term DDD weakens the disc’s outer wall, which can make a sudden herniation more likely to happen during physical exertion.
| Feature | Degenerative Disc Disease (DDD) | Herniated Disc |
| How it develops | Slow wear and tear over years of service. | Sudden rip or tear in the disc wall. |
| Main physical change | The disc loses water, dries out, and flattens. | The soft inner jelly pushes completely out of a crack. |
| Location | Often affects multiple levels of the spine. | Most often affects one specific, isolated spot. |
How the VA Rates Degenerative Disc Disease (38 CFR § 4.71a)
Most cases of Degenerative Disc Disease are evaluated under Diagnostic Code 5242, which covers degenerative changes of the spine. The VA determines a rating based primarily on your Range of Motion (ROM). This is a clinical measurement of how many degrees you can bend your body before pain, stiffness, or structural limits stop you.
The VA splits the spine into two separate areas for evaluation: the Neck (Cervical Spine) and the Lower Back (Thoracolumbar Spine). If you have documented DDD in both areas, they may be evaluated separately.
Spine Rating Chart: Neck vs. Lower Back Range of Motion
| VA Rating | Neck (Cervical Spine) | Lower Back (Thoracolumbar) | What it Means in Plain English |
| 10% | Can bend forward between 31° and 40° | Can bend forward between 61° and 85° | Mild stiffness: Localized pain, stiffness, or muscle spasms that don’t change how you walk. |
| 20% | Can bend forward between 16° and 30° | Can bend forward between 31° and 60° | Moderate stiffness: Severe stiffness or muscle spasms that cause a visible limp. |
| 30% | Can bend forward 15° or less; OR neck is frozen straight. | Not applicable | Severe neck limits: You cannot look down past your chin or nod comfortably. |
| 40% | Neck is permanently frozen in a bent position. | Can bend forward 30° or less; OR lower back is frozen straight. | Severe lower back limits: Your lower back is completely rigid or your forward bending is heavily cut in half. |
| 50% | Not applicable | Lower back is permanently frozen in a bent position. | Severe flattening: Your lower spine is entirely locked in a bent position, making it hard to stand straight. |
| 100% | Not applicable | Not applicable | Total spinal freeze: Both your neck and your lower back are completely frozen and fused together. |
Note: This chart is for general informational reference based on the VA Schedule for Rating Disabilities. The VA utilizes specific goniometric medical testing during an official evaluation to calculate ratings.
The Intervertebral Disc Syndrome (IVDS) Exception
Diagnostic Code 5243 is generally used when Intervertebral Disc Syndrome (IVDS) involving disc herniation and nerve root compression is present. Most standard, uncomplicated DDD claims without active nerve irritation are rated based on your Range of Motion under code 5242.
However, if your medical documentation indicates IVDS with alternating periods of incapacitation, the VA can evaluate your back based on the number of “Incapacitating Episodes” (under medical direction) rather than how far you can bend. When applicable, the VA evaluates the condition under both methods and assigns the higher evaluation.
Documenting Secondary Conditions
Because a primary back rating is based on how far you can bend, veterans often look at how their spinal condition impacts the rest of their body. Secondary conditions are separate medical problems clinically caused or worsened by a primary service-connected condition like DDD:
- Radiculopathy (Sciatica / Nerve Damage): As discs flatten, the exit holes for your nerves can narrow. If you have documented DDD in your lower back, it may cause nerve compression leading to separate evaluations for left or right leg radiculopathy. These may also interact with the VA’s Bilateral Factor bonus.
- Knee, Hip, or Foot Conditions (Altered Gait): Walking with a chronic back condition can force you to limp or shift your weight unevenly. Over time, an altered gait can accelerate wear on the joints of your lower extremities.
- Mental Health Conditions: Managing severe, chronic spine pain can sometimes contribute to secondary conditions like depression, anxiety, or sleep disturbances, which are evaluated under their own diagnostic criteria.
