How VA Rates Lumbar Spinal Stenosis Under DC 5238
The VA rates lumbar spinal stenosis under Diagnostic Code 5238, using either the incapacitating episodes standard or the range-of-motion standard — whichever gives the higher rating. The ICD-10 code for lumbar spinal stenosis is M48.06 (spinal stenosis, lumbar region). Understanding both rating methods is critical to maximizing your claim.
Lumbar spinal stenosis is a narrowing of the spinal canal in the lower back that compresses the spinal cord or nerve roots. For veterans, it most often results from years of heavy load-bearing duty, repetitive lifting, prolonged standing in formation, or a service-connected spine injury that accelerated degeneration.
What Is the Incapacitating Episodes Standard?
An incapacitating episode is a period of bed rest prescribed by a physician because of your spinal condition. VA uses the total number of weeks of incapacitating episodes per year to set your rating under DC 5238.
| Rating | Incapacitating Episodes per Year |
|---|---|
| 10% | At least 1 week but fewer than 2 weeks |
| 20% | At least 2 weeks but fewer than 4 weeks |
| 40% | At least 4 weeks or more |
To use this standard, your treating physician must document each episode of bed rest in your medical records. A personal log or buddy statement alone is not enough — you need physician documentation. If you have frequent flare-ups that force you to bed, talk to your VA primary care provider or private physician about documenting each episode.
Alternative Rating via Range of Motion (DC 5235–5243)
VA must also evaluate your lumbar stenosis using range-of-motion measurements under the General Rating Formula for Diseases and Injuries of the Spine (DC 5235–5243). VA will apply whichever method — incapacitating episodes or range of motion — produces the higher rating.
| Rating | Range of Motion Finding |
|---|---|
| 10% | Forward flexion 60°–85°, or combined ROM 120°–235° |
| 20% | Forward flexion 30°–60°, or combined ROM 60°–120° |
| 40% | Forward flexion 30° or less, or combined ROM 60° or less, or muscle spasm on repeated use |
| 50% | Unfavorable ankylosis of the entire thoracolumbar spine |
| 100% | Unfavorable ankylosis of the entire spine |
Under 38 CFR § 4.59, painful motion counts even if your range of motion is within the normal range. If bending forward causes documented pain before reaching the full normal arc of motion, VA must assign at least a 10% rating.
Neurogenic Claudication: The Hallmark Symptom
Neurogenic claudication — leg pain, cramping, or weakness that appears after walking a short distance and improves with rest or bending forward — is the defining symptom of lumbar stenosis. It differs from vascular claudication because it is caused by compressed nerves, not restricted blood flow.
Document neurogenic claudication thoroughly at your C&P exam. Tell the examiner exactly how far you can walk before symptoms start, how long rest relieves them, and whether you need to lean on a shopping cart or sit down to get relief. These functional limitations directly affect your rating outcome.
Secondary Radiculopathy: A Separate Ratable Condition
Lumbar stenosis frequently compresses the nerve roots that form the sciatic nerve, causing radiculopathy — radiating pain, numbness, or weakness down one or both legs. VA rates radiculopathy of the lower extremity separately under DC 8520 (sciatic nerve) or adjacent codes.
- 10% — mild radiculopathy (intermittent symptoms, minor functional impact)
- 20% — moderate radiculopathy (frequent symptoms, noticeable functional limitations)
- 40% — moderately severe radiculopathy (constant symptoms, significant weakness)
- 60% — severe radiculopathy (marked muscle atrophy, near-paralysis of the extremity)
If both legs are affected, VA rates each leg separately, and the bilateral factor under 38 CFR § 4.26 adds a 10% bonus to the combined value. Visit our Lower Extremity Radiculopathy page for a full breakdown.
How Military Service Causes Lumbar Stenosis
VA does not presume lumbar stenosis is service-connected — you must show a nexus between your military duties and your diagnosis. Strong nexus evidence includes:
- Military Occupational Specialty (MOS) involving heavy lifting, carrying rucksacks, or operating heavy equipment (11B Infantry, 19K Armor Crewman, 88M Motor Transport)
- In-service back injuries documented in your service treatment records
- Training accidents involving falls, parachute landings, or motor vehicle accidents
- Private medical opinion from an orthopedic spine specialist linking your stenosis to military load-bearing activities
Lumbar stenosis is different from degenerative disc disease (DDD), which is a separate condition. If you have both conditions, you can claim them separately — stenosis does not automatically subsume a DDD rating. See the Lumbar Spine Strain page for the overlap between lumbosacral strain and stenosis claims.
Connection to Lumbosacral Strain
Many veterans first file for lumbosacral strain and later develop stenosis. If your stenosis progressed from a service-connected strain, you can claim it as a secondary condition. VA must rate both the primary spine condition and the secondary stenosis if they are documented as separate diagnoses on imaging.
Key Takeaways
- DC 5238 covers lumbar stenosis using incapacitating episodes (10–40%) or range-of-motion measurements — whichever rates higher.
- Four or more weeks of physician-prescribed bed rest per year yields the maximum 40% rating under the incapacitating episodes standard.
- Secondary radiculopathy in one or both legs can be rated separately, significantly increasing your combined rating.
- Heavy load-bearing MOS and documented in-service back injuries are the strongest nexus evidence for stenosis claims.

Frequently Asked Questions
What is the highest VA rating for lumbar stenosis?
Under DC 5238 alone, the maximum rating is 40% (four or more weeks of incapacitating episodes per year). However, if you also have unfavorable ankylosis of the entire thoracolumbar spine under the range-of-motion formula, VA can rate up to 100%. Adding secondary radiculopathy ratings for both legs can push your combined disability percentage significantly higher than 40%.
Does VA presume lumbar stenosis is service-connected?
No. Lumbar stenosis is not a presumptive condition. You must show a direct nexus between your military service and your stenosis diagnosis. A private IMO (Independent Medical Opinion) from a spine specialist strengthens your claim significantly.
Can I get separate ratings for stenosis and radiculopathy?
Yes. VA rates the spine condition (stenosis under DC 5238) and the nerve condition (radiculopathy under DC 8520 or related codes) separately. These are distinct conditions with distinct diagnostic codes, so pyramiding rules do not prevent separate ratings.
What is neurogenic claudication and how does it affect my rating?
Neurogenic claudication is leg pain or weakness that starts after walking a short distance and improves with rest or bending. It is caused by compressed nerves in the stenotic spinal canal. Document exactly how far you can walk before symptoms start — this functional limitation supports a higher rating under VA's functional loss rules at 38 CFR § 4.40.
How do incapacitating episodes work for a VA claim?
An incapacitating episode is a period during which a physician prescribes bed rest for your spinal condition. VA counts the total weeks of prescribed bed rest in a year. Two weeks or more but fewer than four gets you 20%; four weeks or more gets you 40%. Keep a log and make sure your doctor documents each episode in your medical records.
Is lumbar stenosis the same as degenerative disc disease?
No. They are related but separate diagnoses. Degenerative disc disease involves the loss of disc height and hydration between vertebrae. Lumbar stenosis is narrowing of the spinal canal itself, often caused by bone spurs, thickened ligaments, or collapsed discs. If you have both, you can claim them as separate service-connected conditions.
