Neck or Cervical Spine Condition Secondary to Lower Back Disability Claim Guide
A neck or cervical spine condition is sometimes claimed as secondary to a service-connected lower back disability under 38 CFR 3.310. This page reports what published Board of Veterans' Appeals decisions on that theory show. It is an encyclopedic reference, not a forecast.
The Numbers, from 1.9 Million Appeals
In the Board's published decisions, a neck or cervical spine condition claimed as secondary to a service-connected lower back disability is a real, mid-sized claim pool that is an uphill claim once it reaches a merits decision.
How those 1,844 issues came out
Symptoms Recorded in Granted Back and neck (spine) Decisions
Across 17,362 granted Board decisions involving back and neck (spine), these symptoms appear in sentences naming the condition (rating-criteria recitations excluded). Descriptive of the published record, what the Board wrote down, not a checklist of what to report.

ICD-10 Diagnosis Codes for Neck or Cervical Spine Condition
The ICD-10 diagnosis codes most commonly used for DC 5237, Neck or Cervical Spine Condition (the kind on your medical records, decision letter, or C&P exam report). VA rates the disability and its residuals, not the diagnosis itself, so coding can vary.
What a secondary claim on this pairing needs
Under 38 CFR 3.310 a secondary claim turns on three elements:
- A current diagnosis: a medical diagnosis of neck or cervical spine condition (the secondary).
- A service-connected primary: Lower Back Disability, already service-connected (the primary). A 0% primary still counts.
- A medical nexus: a medical opinion linking the neck or cervical spine condition to the lower back disability, showing the primary caused or aggravated it.
See the Secondary Claim guide for the caused-versus-aggravated split, and the Nexus Letter guide for what makes the medical opinion strong.
Why neck or cervical spine condition is claimed secondary to lower back disability
Whether that medical link exists in any one case is a medical question decided on that case's own evidence (the nexus).
Caused By vs Aggravated By: What the Board Found
The outcome split above counts whole issues. This section goes one layer deeper. Under 38 CFR § 3.310 a secondary claim can be won two ways: the lower back disability caused the neck or cervical spine condition (§ 3.310(a)), or it aggravated an existing neck or cervical spine condition (§ 3.310(b)). Every grant rests on one or the other, so the numbers below divide up the granted claims only.
Direct causation is the route that carries most grants here: 90% of them found the lower back disability caused the neck or cervical spine condition, the rest found aggravation. A practical consequence for the nexus opinion: it should address both routes, because a medical opinion that only argues causation leaves the aggravation theory, a separate legal basis, on the table. See the caused-vs-aggravated guide for how the two theories differ.
On the other side: in 9 denied claims the Board looked at this pairing and found no link, meaning it decided the lower back disability neither caused nor worsened the neck or cervical spine condition. That is a separate group from the grants above, counted here so the picture is not one-sided.
Read from published Board decisions on this pairing. The grant split covers granted claims only; denied, remanded, and dismissed claims are not in it. Descriptive of the published record, not a prediction.
What VA Looks For: Tests, Records, and Diagnostic Codes
The record VA actually reviews centers on a small set of documents. In published Board decisions on these claims, the records that appeared most often, in order, were:
- A medical nexus opinion: the one record VA weighs most on a secondary claim, a doctor's statement linking your neck or cervical spine condition to your service-connected lower back disability and naming the mechanism.
- Range of motion measured in degrees
- Flare-ups and additional functional loss addressed
- In-service back or neck injury documented
- Radiculopathy or EMG/nerve-conduction findings
- MRI or imaging of the spine
- Physician-prescribed bed rest
The diagnostic code involved: DC 5237 (Neck or Cervical Spine Condition). The rating levels for this code are in the rating section below.
Records ranked by how often published Board decisions cited them. The exam that captures most of this is covered in the C&P Exam section below. Source: Board of Veterans' Appeals decisions, RateMyVSO analysis.
The Evidence That Wins This Claim
What veterans who win this pairing actually put in the file, and why each piece moves the claim.
- Your back treatment records from day one: Get every treatment note, imaging report, and visit record for your service-connected lower back condition, starting as early as you have them. This anchors the whole claim. If the VA can't confirm how bad your back condition really is, they can't evaluate whether it caused problems in your neck.
- Neck imaging (MRI or CT): You need current imaging showing disc damage, bone spurs, or nerve compression in your cervical spine. Look for words like "cervical spondylosis" or "disc-osteophyte complex" on the radiology report. This proves the neck condition is real, not just something you're describing.
- An exam that documents your posture and walk, not just your neck: Ask your doctor to write down forward head posture, an uneven or favoring gait, limited neck motion, and any positive nerve tests (like Spurling's test). This is the evidence that connects your back to your neck. A neck exam alone, without mentioning your gait or posture, gives the VA nothing to link the two conditions.
- A clear timeline: Write down or have your doctor note when your neck symptoms started compared to when your back condition began or got worse. If your neck problems showed up or worsened after your back injury, that timeline is your best weapon against a "that's just aging" denial.
- A nexus letter from a spine specialist, not a general doctor: The letter should come from an orthopedic surgeon, neurosurgeon, or physiatrist who examined you personally. It must say your neck condition is "at least as likely as not" caused or worsened by your back condition, and explain the mechanism: your back problem changed how you walk and stand, which put extra strain on your neck over time, speeding up the wear and tear there. Vague statements like "this could be related" get denied.
- The causation-versus-aggravation distinction, stated plainly: If your neck was fine before your back injury, the letter should say the back condition caused the neck problem. If you already had some neck trouble before, the letter should say the back condition made it worse, faster, than it would have gotten on its own. Getting this wrong, or leaving it vague, is one of the most common reasons these claims get denied.
- Proof you've been treated for your back, not just diagnosed: Physical therapy notes, injection records, and pain management history show your back condition is serious enough to cause real physical compensation, not a minor issue. This backs up the "your neck absorbed the load" story medically.
- A direct answer to the "multiple causes" denial: If the VA says your neck problem could be from aging, genetics, or general wear, get your doctor to state plainly that your back condition sped up the damage beyond normal aging. The law does not require your service-connected condition to be the only cause, just that it's at least as likely as not a contributing one.
Evidence Cited in Published Back and neck (spine) Decisions
We read 192,392 published Board decisions involving back and neck (spine) for condition-specific evidence, counting only case-specific mentions (boilerplate recitations excluded). "Favorable" is the share of decisions citing that evidence where every issue was granted or the outcome was mixed; the baseline across all these decisions is 61.2%, combining every diagnostic code below. Evidence appearing in a decision does not mean it decided the case. Descriptive of the published record, not a prediction.
By diagnostic code
These codes are grouped together above. They do not perform the same, so find your own code here rather than reading the combined figure. Codes retired in the schedule rewrites are left out, because their old decisions were judged under criteria that no longer apply.

Board Grants on This Theory, Dissected (expand to read)
Several Board decisions have granted service connection for a neck (cervical spine) condition as secondary to an already service-connected low back disability. In each case below, the Veteran had a service-connected low back disability, a diagnosed neck condition, and a medical opinion linking the two. These decisions are not binding on other cases, and each claim is decided on its own facts and evidence.
Cervical DDD and both arms' radiculopathy tied to service-connected low back Citation A26031667 (April 2026), Hearing docket
The record: The Veteran was service-connected for lumbar degenerative disc disease (DDD). A private disability benefits questionnaire (DBQ) diagnosed cervical DDD along with left and right upper extremity radiculopathy. The private clinician explained that low back arthritis causes instability and weakness at other discs, leading to deterioration and nerve compression in the cervical spine. A VA medical opinion disagreed, stating simply that low back DDD does not cause arthritis at the neck.
Why it won: The Board found the VA opinion unpersuasive because it "does not provide much support for her conclusion." The Board found the private opinion's explanation of how instability at the low back travels up the spine and compresses nerve roots to be persuasive, and it resolved doubt in the Veteran's favor.
Neck strain linked to posture and compensation from service-connected back Citation A26029820 (April 2026), Hearing docket
The record: The Veteran had a service-connected lumbar spine disability. A June 2020 VA exam diagnosed cervical strain but found no link to the back, reasoning only that there were no records connecting the two conditions and that a lumbar strain would not affect the neck without a serious gait or ambulation problem. A September 2025 private opinion from the Veteran's treating physician, Z.S., MBBS, explained that the low back disability altered the Veteran's posture and gait, increased her risk of overuse injury, and contributed to a general pain pattern that led to the neck condition, with no other cause shown.
Why it won: The Board called the June 2020 VA opinion "conclusory," noting it did not explain why missing records mattered medically and ignored the Veteran's lay statements about her posture. The private opinion was found adequate because it was based on an exam, a records review, and a clear explanation connecting the back condition to the neck.
Neck and arm radiculopathy granted after Board hearing testimony Citation A26026702 (March 2026), Hearing docket
The record: A VA examiner diagnosed cervical DDD and left arm radiculopathy but opined the neck condition was not related to the lumbar spine because there was "no common medical knowledge or medical evidence to support a causal relationship." The examiner gave no opinion on the arm radiculopathy at all. A private physician, Dr. C.R., examined the Veteran, reviewed his records, and explained that the spine is mechanically connected through ligaments, tendons, discs, and facet joints, so a breakdown in the low back leads to overuse and deterioration in the neck over time, which in turn compressed nerves affecting the arm.
Why it won: The Board gave the VA opinion "some weight" because of its limited rationale, but gave Dr. C.R.'s opinion "great weight" because it explained the specific mechanical connection between the low back and the neck. The Board resolved doubt in the Veteran's favor for both the neck and the arm condition.
Cervical arthritis granted where VA's own exam supported the link Citation A26024677 (March 2026), Hearing docket
The record: A November 2019 VA examiner, after reviewing the record and examining the Veteran, opined it was at least as likely as not that the cervical spine condition was secondary to the service-connected lumbar spine condition, discussing the specific anatomy involved and citing medical literature. Two later VA examiners (January 2020 and August 2020) disagreed, stating a low back condition could not cause a neck condition without a significant gait disturbance or a fall.
Why it won: The Board found the November 2019 opinion "highly probative" due to its thorough review and reference to medical literature. It found the two later opinions "less than probative" because they offered only a conclusory rationale and ignored whether the neck condition had worsened over time, an issue relevant to aggravation.
Neurosurgeon's explanation of spinal compensation outweighs general VA opinion Citation A26016007 (February 2026), Evidentiary window limited by withdrawn hearing
The record: A VA examiner attributed the Veteran's cervical arthritis and disc disease to aging, explaining in general terms how spinal discs dehydrate over time, but did not address the Veteran's specific situation or discuss aggravation. The Veteran's treating neurosurgeon wrote a letter stating that after a lumbar fusion, a person walks and holds their body differently, putting stress on the discs above the affected area, including all the way up to the cervical spine.
Why it won: The Board found the VA opinion "general in nature" and not persuasive. It found the neurosurgeon's letter more probative because it addressed the Veteran's own case, and found the Veteran's account that his neck pain began after his back surgery to be credible.
Neck disability granted alongside an unrelated sinusitis increase Citation A26002743 (January 2026), Hearing docket (withdrawn)
The record: The Veteran was service-connected for degenerative arthritis of the lumbar spine. An October 2019 VA opinion found no medical relationship between the back and the neck, citing a lack of supporting medical literature and too large a time gap between the two conditions, and did not address aggravation. A June 2020 private opinion explained that chronic dysfunctional motion in the low back can and does translate to the cervical spine over time, causing chronic misalignment and injury, and noted no other injury explained the Veteran's neck pain.
Why it won: Resolving reasonable doubt in the Veteran's favor, the Board found the evidence favored a finding that the neck disability was caused or aggravated by the service-connected lumbar strain.
Why VA Denies, and How the Board Answered
The rationales below are the ones VA examiners actually used against this theory in the published record, each paired with the Board's response.
- Read the left column first: if a VA opinion in your file uses one of these arguments, that is the reasoning your own evidence has to meet.
- The right column is the counter: it shows how the Board actually answered that argument, with the decision cited.
- A rationale appearing here is not a verdict: the same argument won some cases and lost others, on different records.
| VA examiner's rationale | How the Board answered it |
|---|---|
| "Low back DDD does not cause arthritis at the neck," stated without further support. | The Board found the opinion unpersuasive because it lacked a reasoned explanation connecting the conclusion to any supporting data (A26031667). |
| A lumbar strain would not cause neck symptoms unless the entire spine were involved, which would likely show up as an inability to drive or walk normally. | The Board called this rationale "conclusory," noting it did not explain why the absence of records was medically significant and ignored the Veteran's lay statements about her posture (A26029820). |
| A low back condition cannot cause or aggravate a neck condition without a significant, prolonged gait disturbance or a fall injury. | The Board found this rationale "less than probative" because it was conclusory and did not address whether the neck condition had worsened over time, which matters for aggravation (A26024677). |
| The neck condition is a normal result of aging discs, described in general physiological terms. | The Board found this opinion "general in nature" and gave more weight to the Veteran's treating neurosurgeon, who explained the specific effect of the Veteran's fusion on his posture and neck (A26016007). |
| The cervical spine and lumbar spine are separate diagnoses, with no medical evidence connecting them; there is no anatomical relationship supported by treatment records. | The Board found this reasoning adequate when it addressed the Veteran's specific anatomy and record, and denied the claim because the negative opinions outweighed the Veteran's own belief in a connection (A25100163). |
| There is no service-connected lumbar spine disability on file to serve as the basis for a secondary neck claim. | The Board explained that secondary service connection cannot be granted as a matter of law without a service-connected primary disability, and denied the neck claim on that basis (A25108641). |
If Granted: How Neck or Cervical Spine Condition Is Rated
The VA assigns one of these percentages based on what your medical record documents. Plain-language summary of the rating criteria at 38 CFR; the controlling text is the regulation itself.
| Rating | What the record has to show for DC 5237, Neck or Cervical Spine Condition |
|---|---|
| 100% | Your entire spine has fused together in a bad position that severely limits your ability to move your back and neck (unfavorable ankylosis means the bones have grown together abnormally). This complete fusion makes it extremely difficult or impossible to bend, twist, or turn your spine in any direction, significantly impacting your daily activities and quality of life. |
| 50% | Your entire middle and lower back spine has fused together in a way that severely limits your movement and function. Unfavorable ankylosis means the vertebrae (spine bones) have grown together abnormally, creating a rigid, inflexible spine that significantly restricts your ability to bend, twist, or move your back normally. |
| 40% | You qualify for this rating if your entire neck is fused or locked in place in a bad position (unfavorable ankylosis), or if you can only bend forward 30 degrees or less in your mid to lower back, or if your entire mid to lower back is fused in a good functional position (favorable ankylosis). Ankylosis means your spine joints have become stiff and immobile, either naturally from your condition or surgically fused together. |
| 30% | You qualify for this rating if your neck can only bend forward 15 degrees or less (normal is about 50 degrees), or if your entire neck spine has fused together in a good position (favorable ankylosis means the bones have grown together but in a way that doesn't cause major problems). This represents severe limitation in neck movement that significantly restricts your ability to look down or bend your head forward. |
| 20% | You qualify for this rating if your back or neck injury limits how far you can bend forward - either bending your back forward between 30-60 degrees or bending your neck forward between 15-30 degrees. You also qualify if your overall spine movement is significantly restricted (back movements totaling 120 degrees or less, neck movements totaling 170 degrees or less), or if you have severe muscle spasms that cause you to walk abnormally or develop visible spine curvature like a hunched back, loss of natural back curve, or sideways spine curvature. |
| 10% | You qualify for this rating if your spine injury limits how far you can bend forward - either to about shoulder height for your lower back or chin-to-chest level for your neck. You also qualify if you have muscle spasms, stiffness when moving (guarding), or tender spots along your spine that don't cause you to walk differently or change your spine's normal curves. Additionally, you qualify if X-rays show a vertebral fracture where the bone has collapsed by half or more of its original height. |
Do's and Don'ts
Every item below comes from a pattern in the decisions on this pairing, not from general claim advice.
- Get a medical opinion that explains the specific mechanical or anatomical connection between your low back and your neck, not just a general statement that a link is possible.
- Make sure your low back disability is already service-connected before you file a secondary neck claim, since secondary service connection cannot stand without it.
- Ask any doctor who examines you to address both causation and aggravation, and to explain how your condition would look if the back disability were not present.
- Bring your full medical history and lay statements about how and when your neck symptoms started to any private examiner writing an opinion for you.
- Point out to VA if a negative opinion offers only a bare conclusion, such as "the spine regions are separate," without discussing your own records or history.
- Don't expect a claim to succeed if there is no current diagnosis of a neck condition anywhere in your file.
- Don't rely only on a private opinion addressing aggravation if it does not establish how bad your neck condition was before any aggravation happened.
- Don't assume a VA examiner's opinion that "the spine regions are separate" will be accepted at face value. Some Board decisions accepted this reasoning and some rejected it, depending on how well it was explained.
- Don't submit a claim for a secondary neck condition if the back disability it is supposed to stem from is not yet service-connected.
- Don't overlook treatment records showing physical therapy, gait problems, or posture issues tied to your back. Several grants relied heavily on this kind of evidence.
Quick Checklist Before You File
- Service connection already in place for Lower Back Disability, and a current medical diagnosis of neck or cervical spine condition.
- Diagnostic testing, imaging, or clinical records documenting the neck or cervical spine condition, whatever your provider used to diagnose and track it.
- A nexus opinion, whenever possible from a doctor familiar with neck or cervical spine condition, stating it is at least as likely as not caused or aggravated by the lower back disability, and naming the mechanism rather than just the conclusion.
- Lay statements: spouse, family, friends, or battle buddies describing what they've witnessed or noticed.
- Your STRs and any VA opinions already in the file on either condition. If a VA opinion already went against you, your submitted opinion or statement should address its specific reasoning.
For the mechanics of filing itself, see the Standard Claim Guide and the Fully Developed Claim Guide.
The Claims Process, Step by Step
A secondary claim moves through the same pipeline as any other. Understanding who does what helps you know who to contact and what to expect.
- You file the claim, naming Lower Back Disability as the service-connected primary and neck or cervical spine condition as secondary. Directly with VA, through VA.gov, or with an accredited representative's help.
- VA assigns a Veteran Service Representative (VSR) to develop the claim: gather your service treatment records, VA and private medical records, and order a C&P exam if needed.
- The C&P exam is conducted, usually with the examiner asked to address the specific secondary theory (causation and aggravation both).
- The file goes to a Rating Veteran Service Representative (RVSR), the "rater," who weighs the medical evidence and decides service connection and, if granted, the rating percentage.
- VA issues the decision letter stating the outcome and the reasoning.
- If denied or under-rated, you choose an appeal lane, Supplemental Claim, Higher-Level Review, or a Board appeal, covered below.
Who's who: VSO vs. VSR vs. Rater vs. C&P Examiner
Your VSO
An accredited representative, agent, or attorney. Not a VA employee. Helps prepare and file, and can represent you on appeal. Has no authority to decide your claim.
VSR
VA staff who develops the claim: gathers records and schedules the exam. Does not decide the rating.
Rater (RVSR)
VA staff who reviews the complete file and makes the actual decision on service connection and percentage.
C&P Examiner
Conducts the exam and, where asked, gives a nexus opinion. Does not decide the claim, but the opinion's reasoning and legal framing carry real weight.
For the full walkthrough, see Inside Your Claim and Claim Stages.
DBQs and Your C&P Exam
A Disability Benefits Questionnaire (DBQ) is the standardized form the examiner completes for your condition. See the DBQ Guide for how these forms work and whether a private DBQ from your own doctor can be submitted instead of relying solely on a VA exam. For what to expect and how to prepare, see the C&P Exam Prep Guide, and be specific about how your neck or cervical spine condition symptoms relate to your lower back disability timeline, treatment, and any aggravation, that is the detail a nexus opinion relies on.
Reading Your Decision Letter, and What to Do If Denied
Your decision letter has a narrative "reasons and bases" section and a codesheet with the rating and effective date. See the Reading Your Decision Letter Guide or use the Letter Interpreter tool to decode your own letter. If denied, you have three main lanes:
- Supplemental Claim: refile with new and relevant evidence, such as a nexus opinion that addresses the mechanism and the specific VA rationale you're rebutting. See Supplemental Claim Guide.
- Higher-Level Review (HLR): a senior reviewer looks at the same evidence again, useful if the denial rested on a legal error. See HLR Guide.
- Board Appeal: your case goes to a Veterans Law Judge, with a direct review, evidence, or hearing docket. See Board Appeal Guide.
Not sure which lane fits? See the Appeals decision guide for a side-by-side comparison.
After You Win: Maintaining Your Rating
Keep documentation of ongoing treatment, follow-up evaluations, and any updated diagnostic testing for your neck or cervical spine condition on file, this protects you if VA schedules a future reexamination. See Protect Your Rating for when a rating becomes protected and Future Reexaminations for what triggers one. If your neck or cervical spine condition worsens, see the Rating Increase Guide.
Frequently Asked Questions
Does Lower Back Disability have to be highly rated to support a neck or cervical spine condition secondary claim?
No. 38 CFR 3.310 looks at whether the service-connected Lower Back Disability caused or aggravated the neck or cervical spine condition, not at how severe the Lower Back Disability rating is. Even a 0% service-connected primary can anchor a secondary claim.
