How to Get a Sciatica VA Rating

The Department of Veterans Affairs (VA) assigns disability ratings for service-connected sciatica ranging from 10 to 80 percent. These ratings vary based on symptom severity and which of the three categories of nerve issues the veteran’s sciatica falls into.

In this article, you will learn more about the possible sciatica VA ratings, as well as what evidence you may need to support your claim and how to file that claim with VA.

Key points of this article include:

• Sciatica is usually rated as paralysis (Diagnostic Code 8520), neuritis (DC 8620), or neuralgia (DC 8720) of the sciatic nerve, respectively, each of which has its own rating criteria and percentages.
• Most sciatica claims are actually established on a secondary basis by linking it to already service-connected conditions like back issues.
• Though VA has proposed changes to the rating criteria for sciatica, these changes have not been implemented as of September 2026.

What Is Sciatica?

Sciatica is a nerve condition in which pain radiates along the path of the sciatic nerve, traveling from the lower back down through the legs. This condition is a particular form of lumbar radiculopathy, which is a compressed or pinched nerve located in the spine.

In its 2025 Annual Benefits Report, VA claimed that over 2 million veterans receive VA compensation for paralysis of the sciatic nerve, making it the most commonly service-connected neurological condition.

Sciatica most often occurs when the sciatic nerve is compressed or pinched, typically by a herniated disc in the spine or an overgrowth of bone on the vertebrae.

Usually, sciatica affects only one side of the body. Common symptoms include:

• Numbness
• Tingling
• Burning sensation
• Muscle weakness

To earn a sciatica VA rating, a veteran must provide enough evidence to show that the sciatica was directly or secondarily (indirectly) caused by service.

How Do I Prove Direct Service Connection for Sciatica?

To earn direct service connection for sciatica, a veteran must prove that their condition is directly linked to an event that happened during the veteran’s military service.

Under 38 CFR § 3.303, veterans generally need three things to establish direct service connection for sciatica:

• A current diagnosis of sciatica or sciatic nerve paralysis;
• Evidence of an in-service injury, disease, or event that could explain the nerve damage (e.g., a back injury during training, or a fall); and
• A medical nexus opinion connecting the current diagnosis to that in-service event.

It is important for veterans to note that direct claims are less common for sciatica than secondary claims, since sciatic nerve irritation usually develops gradually from an underlying spine condition rather than from a single documented incident.

See “What Evidence Do I Need” below to continue researching direct service connection for sciatica.

How Do I Prove Secondary Service Connection for Sciatica?

Under 38 CFR § 3.310, a veteran can earn secondary service connection for sciatica by proving the condition has been caused or aggravated by a separate, already service-connected disability.

To establish secondary service connection, veterans generally need to provide three pieces of evidence to VA:

• A current sciatica diagnosis;
• Evidence of an already service-connected primary condition that could have caused the sciatica to develop; and
• A medical nexus opinion stating it is “at least as likely as not” that the primary condition caused or aggravated the sciatica.

“The nexus, or connection between your primary condition and your secondary condition must be clearly established to be granted secondary service connection,” says Emma Peterson, partner at CCK Law.

It is important to note that secondary service connection is actually the path most veterans use to connect sciatica to their service, since sciatic nerve irritation is often a downstream effect of another condition rather than a stand-alone injury.

What Primary Conditions Can Cause Sciatica as a Secondary Condition?

It is most common for musculoskeletal conditions (specifically back conditions) to trigger the secondary development of sciatica. This is because service-connected back conditions often compress or irritate the sciatic nerve, which can gradually develop into sciatica over time.

Some primary back conditions that often cause or aggravate sciatica include:

• Herniated discs
• Spondylolisthesis
• Spinal stenosis
• Degenerative disc disease
• Osteoarthritis

Other types of disabilities can also lead to or contribute to sciatica. These include:

• Diabetes — Veterans with diabetes often suffer from nerve damage as a result of their condition, which can ultimately lead to sciatica.
• Obesity — Veterans rendered immobile by a service-connected condition often gain significant weight, which puts additional strain on the spine that can cause or worsen sciatica.
• Piriformis syndrome — Sometimes veterans experience issues with their piriformis muscle, located in the buttock. If this muscle begins to spasm, it can compress the sciatic nerve and lead to sciatica.
• Musculoskeletal disabilities of the hip, knee, foot, and other areas — Veterans with mobility and joint issues sometimes shift how they walk in order to minimize pain or awkwardness. Over time, this altered gait can place stress on the back and compress the sciatic nerve.

Veterans should also be aware that the chronic pain caused by sciatica can itself lead to other disabilities that can be service connected on a secondary basis, including sleep disturbances or mental health disorders like depression and anxiety.

See “What Evidence Do I Need” below to continue researching secondary service connection for sciatica.

What Evidence Do I Need To Prove a Sciatica Claim?

Whether pursuing direct or secondary service connection, a sciatica claim needs the same foundation of a current diagnosis, an in-service event or qualifying service-connected primary condition, and a medical nexus opinion.

Beyond these three elements, however, there is also important medical evidence that can help establish the existence and severity of a veteran’s sciatica, including:

• Imaging — Magnetic resonance imaging (MRI) or computed tomography (CT) scans can show nerve compression or a herniated disc.
• Nerve testing — Electromyography (EMG) or nerve conduction studies (NCS) can document motor loss, denervation, or slowed nerve signals.
• Examination findings — Reduced reflexes, muscle atrophy, or diminished strength testing can be recorded during a medical examination.
• Treatment history — Consistent records, including physical therapy notes and pain management history, can help show the progression of the condition over time.

Objective medical testing like this is particularly important for conditions of the nerve, since under 38 CFR § 4.124a, evidence that is subjective or “wholly sensory” only allows for a rating of mild or moderate at best. To earn higher sciatica VA ratings, objective medical tests are usually necessary.

However, this is not to say that subjective evidence is worthless. In fact, lay statements from the veteran, family members, and fellow service members can also help to bolster a sciatica claim.

These personal accounts about the veteran’s sciatica often cover how it affects things like their work, sleep, and other daily activities, which helps examiners connect medical findings to real functional loss.

How Do I File a VA Sciatica Claim?

Veterans can file an initial or increased sciatica claim by submitting VA Form 21-526EZ.

In addition to filing this form, veterans should consider taking the following steps:

1. Even before you have your evidence, you can submit VA Form 21-0966 (Intent to File) to lock in an effective date while preparing your claim. This should increase your back pay once you win your claim.
2. Collecting service treatment records, current medical records, and a nexus opinion linking sciatica to service or to a service-connected condition.
3. Completing VA Form 21-526EZ online at VA.gov, by mail, or with help from a VA-accredited representative.
4. Attending any scheduled Compensation and Pension (C&P) examination, where an examiner documents current symptoms and severity.

Once VA issues a decision, the rating decision letter explains whether service connection was granted and, if so, the assigned percentage.

What Are the Possible Sciatica VA Ratings?

The decision letter from a successful claim will include a sciatica VA rating of 10 to 80 percent depending on the nature of the veteran’s particular nerve issues.

“So typically VA rates sciatica under their neurological conditions, specifically nerve issues,” says Michelle DeTore, supervising advocate at CCK Law. “You’ll see sciatica fall into three different categories based on the severity of the symptoms.”

The three categories sciatica is usually rated under include:

• Paralysis of the sciatic nerve — The most severe category of sciatica, paralysis often involves loss of muscle function and provides possible VA ratings of 10 to 80 percent.
• Neuritis of the sciatic nerve — This category typically involves inflammation of the nerves and provides possible disability ratings from 10 to 60 percent.
• Neuralgia of the sciatic nerve — The most common category of sciatica that veterans are rated under, neuralgia usually involves chronic or intense intermittent pain of the nerve and offers ratings of 10 or 20 percent.

Each of these three categories of nerve conditions also has sub-categories for mild, moderate, or severe symptoms, creating many different possible ratings for a condition that affects a nerve.

VA rates sciatica under 38 CFR § 4.124a, Schedule of Ratings – Neurological Conditions and Convulsive Disorders, as follows:

Paralysis of the Sciatic Nerve – Diagnostic Code 8520

VA Rating for Paralysis of Sciatic Nerve	Rating Criteria
80 percent	Complete paralysis in which all the muscles of the leg below the knee fail to work, causing serious difficulty in bending the knee
60 percent	Incomplete but severe paralysis marked by muscular atrophy, poor blood circulation, and limited functionality of the affected body part
40 percent	Incomplete but moderately severe paralysis
20 percent	Incomplete but moderate paralysis
10 percent	Incomplete but mild paralysis

Neuritis of the Sciatic Nerve – Diagnostic Code 8620

VA Rating for Neuritis of Sciatic Nerve	Rating Criteria
60 percent	Severe neuritis marked by a loss of reflexes, loss of sensation, and muscle atrophy; seriously limited functionality of the affected body part
40 percent	Moderately severe neuritis
20 percent	Moderate neuritis
10 percent	Mild neuritis

Neuralgia of the Sciatic Nerve – Diagnostic Code 8720

VA Rating for Neuralgia of Sciatic Nerve	Rating Criteria
20 percent	Moderate neuralgia involving tingling, numbness, and moderate to severe pain, along with interference with the affected limb’s functionality
10 percent	Mild neuralgia causing tingling or mild pain, with only minor interference with the limb’s functionality

Importantly, there is no disability rating for severe neuralgia.

How Does Bilateral Sciatica (Both Legs) Affect VA Compensation?

VA considers a disability “bilateral” when it affects both sides of a veteran’s body (e.g., both their right leg and their left leg). If a veteran’s sciatica affects both of their legs, it is possible VA will acknowledge the veteran’s condition as bilateral.

This is important because of the Bilateral Factor, a VA regulation (38 CFR § 4.26) stating that it recognizes bilateral disabilities as being particularly disabling, and therefore deserving of additional compensation.

Under the Bilateral Factor, VA may assign separate sciatica disability ratings for each of a veteran’s affected legs. It will then combine these ratings and add an additional 10 percent to the resultant combined disability rating, potentially resulting in higher compensation for the veteran.

Veterans should note, however, that this additional 10 percent will not be added as a flat increase, but will instead be factored into the VA math equation used to determine the veteran’s overall rating.

Can Sciatica Qualify for TDIU (Unemployability)?

Yes, it is possible to earn total disability for sciatica. After all, sciatica can be incredibly difficult to live with and, in severe cases, can cause difficulty in walking and paralysis.

Veterans with severe sciatica may require the assistance of canes, wheelchairs, or other assistive devices to walk. As such, veterans living with sciatica may have trouble with many activities of daily living, including working certain jobs.

Total disability based on individual unemployability, or TDIU, is a monthly benefit available to veterans who are prevented from working due to their service-connected disability or disabilities. This benefit compensates veterans at the 100 percent level, even if their combined disability rating does not equal 100 percent. TDIU is essentially an alternative path to receiving maximum benefits.

Eligibility for TDIU

VA outlines TDIU regulations under 38 CFR § 4.16. TDIU can be awarded on a schedular or extraschedular basis.

The criteria for schedular TDIU (§ 4.16(a)) is as follows:

• One service-connected condition rated at 60 percent or higher; or
• Two or more service-connected conditions, one of which is rated at 40 percent or higher, with a combined rating of 70 percent or higher.

Veterans who do not meet the schedular requirements may still be considered for extraschedular TDIU under § 4.16(b).

What Happens if VA Rates Sciatica as 0% or Denies the Claim?

Veterans can often appeal a denied sciatica claim to potentially have VA’s decision reversed and the claim approved. On the other hand, a sciatica claim rated at 0 percent still means VA has acknowledged the veteran’s condition is service connected, which may make it easier for the veteran to file increased ratings claims for sciatica in the future.

For veterans whose sciatica claims were denied, there are typically three appeal options they can take to get VA to change its decision. No matter which of these a veteran chooses, however, they should be sure to submit the appeal within one year of the decision date in order to preserve the effective date for their claim.

The three appeal options a veteran can take include:

• A Supplemental Claim (VA Form 20-0995) with new evidence;
• A Higher-Level Review (VA Form 20-0996) for a fresh look at the existing record from a more senior VA rater; or
• A Board Appeal (VA Form 10182) before a Veterans Law Judge. Filing within one year of the decision date generally preserves the original effective date.

If the veteran instead received a 0 percent, or noncompensable, rating for their sciatica, it is not actually the worst outcome for the claim. VA assigns this rating when the veteran’s current symptoms do not yet meet the compensable threshold under 38 CFR § 4.124a.

However, this rating still has value, since it indicates that one of the most challenging parts of the claims process (i.e., establishing service connection) is now completed. This means if a veteran’s symptoms worsen in the future, they may have an easier time filing for an increased rating supported by new medical evidence.

What Are the Complaints About the VA Rating System for Sciatica?

Veterans and advocates have raised concerns in the past regarding how VA rates sciatica.

Sciatica ratings are usually based on whether the sciatica is mild, moderate, moderately severe, or severe. These terms, which the rating schedule uses, are highly subjective and vaguely defined. With the exception of severe incomplete paralysis, there are no specific symptoms listed in the rating criteria that veterans must have to receive a rating of mild, moderate, or moderately severe sciatica.

In 2026, the U.S. Government Accountability Office (GAO) issued a report that said vague or outdated VA rating criteria have been leading to unfair and arbitrary decision-making. While one veteran may have specific symptoms and the regional office finds that they have moderate sciatica, another veteran could have those same symptoms and be judged as having mild sciatica.

The report recommended VA create concrete criteria for determining whether neurological impairment related to the spine is mild, moderate, or severe.

VA does have some additional criteria regarding sciatica in its Adjudication Procedures Manual, or the M21. However, the criteria listed there can also be subjective. This leaves room for many different interpretations and inconsistencies between the regional offices, Veterans Law Judges at the Board of Veterans’ Appeals (BVA), and more.

Proposed Update to Sciatica Ratings

In November 2024, VA proposed updates to the rating criteria for sciatica. These updates would replace the current rating system with one that aligns with the Medical Research Council (MRC) Scale for Muscle Strength.

This scale is well-known in the medical community and could add more objectivity to the rating criteria for sciatica. Under this scale, VA would rate sciatica on a scale of 0 to 5 based on muscle strength, rather than using the current criteria of mild, moderate, moderately severe, or severe.

As of September 2026, however, these new rating criteria are still in the proposal stage and have not been finalized by VA. While it is possible they will be implemented sometime in the future, it is also possible VA may change the proposed criteria further, or even dispense with the changes completely.

Frequently Asked Questions

Is sciatica the same as lumbar radiculopathy for VA purposes?

Not exactly, though the terms frequently overlap. Sciatica describes pain along the sciatic nerve and is the form of lumbar radiculopathy VA most commonly rates, using DC 8520, 8620, or 8720. Lumbar radiculopathy is the broader term for any pinched nerve root in the lower back and can occasionally point to a different lower-extremity nerve, which would call for a different diagnostic code.

Do I need an EMG or nerve conduction test to prove my sciatica rating?

An EMG or nerve conduction study (NCS) is not strictly required, but it substantially supports a sciatica claim. These tests provide objective evidence of nerve damage that can support ratings above the mild level, since sensory symptoms alone are generally limited to the mild or moderate rating under 38 CFR § 4.124a.

What’s the difference between DC 8520, 8620, and 8720 for sciatica?

All three codes fall under 38 CFR § 4.124a and share the same rating scale, but they apply to different symptom patterns. DC 8520 covers paralysis of the sciatic nerve and can be rated from 10 to 80 percent. DC 8620 covers neuritis and caps at 60 percent, the severe incomplete paralysis level. DC 8720 covers neuralgia and caps at 20 percent, the moderate level.
