Back or Neck Strain Secondary to Shoulder or Arm Limitation Claim Guide

We analyzed the Board's published decisions and found back or neck strain (DC 5237) claimed as secondary to shoulder or arm limitation (DC 5201) is a real, mid-sized claim pool that is an uphill claim once it reaches a merits decision.

How those 555 issues came out

The ICD-10 diagnosis codes most commonly used for DC 5237, Back or Neck Strain (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.

See the full diagnostic-code page →

Under 38 CFR 3.310 a secondary claim turns on three elements:

• A current diagnosis: a medical diagnosis of back or neck strain (the secondary).
• A service-connected primary: Shoulder or Arm Limitation, already service-connected (the primary). A 0% primary still counts.
• A medical nexus: a medical opinion linking the back or neck strain to the shoulder or arm limitation, 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.

Whether that medical link exists in any one case is a medical question decided on that case's own evidence (the nexus).

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 shoulder or arm limitation caused the back or neck strain (§ 3.310(a)), or it aggravated an existing back or neck strain (§ 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: 86% of them found the shoulder or arm limitation caused the back or neck strain, 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 48 denied claims the Board looked at this pairing and found no link, meaning it decided the shoulder or arm limitation neither caused nor worsened the back or neck strain. That is a separate group from the grants above, counted here so the picture is not one-sided.

We analyzed published Board decisions on this pairing to build this split. The grant split covers granted claims only; denied, remanded, and dismissed claims are not in it. Descriptive of the published record, not a prediction.

The record VA actually reviews centers on a small set of documents. We analyzed published Board decisions on these claims and ranked the records that appeared most often:

• A medical nexus opinion: the one record VA weighs most on a secondary claim, a doctor's statement linking your back or neck strain to your service-connected shoulder or arm limitation and naming the mechanism.
• Range of motion measured in degrees
• In-service back or neck injury documented
• Flare-ups and additional functional loss addressed
• Radiculopathy or EMG/nerve-conduction findings
• MRI or imaging of the spine
• Physician-prescribed bed rest

The diagnostic code involved: DC 5237 (Back or Neck Strain). 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.

What veterans who win this pairing actually put in the file, and why each piece moves the claim.

• MRI of the cervical or lumbar spine: This is the imaging that shows the actual damage, disc herniation, a narrowed nerve channel (foraminal stenosis), or bone spurs pressing on a nerve. Ask that the report list the exact level (for example C5-C6) and which side. A nexus letter is much stronger when it can point to a specific level that matches your symptoms.
• Nerve testing (EMG/NCS) if you have numbness, tingling, or weakness running down your arm or leg: This test measures whether a nerve root is actually misfiring, not just pinched on a picture. It backs up the MRI with hard, objective proof, and it matters most when the imaging alone is not convincing on its own.
• Detailed exam notes from your doctor, not just "positive neuro exam": You want your file to show specific findings, a positive Spurling test (head tilted toward the sore side reproducing arm pain), numbness in a specific finger or area, weak muscles on one side, or a weak reflex. Vague notes get denied. Specific findings tied to a nerve level get approved.
• Physical therapy and treatment notes documenting how you moved differently because of your shoulder or arm limitation: The chain VA needs to see is: shoulder problem forced you to hold your neck or back differently, that abnormal posture over time strained the spine and pinched a nerve. PT notes describing altered posture, reduced range of motion, or your body compensating are the paper trail that proves this chain actually happened.
• A clear timeline showing your neck or back symptoms started after the shoulder or arm limitation, not before: Get dates. When did the shoulder problem start, when did the neck or back pain start. VA often denies these claims by arguing the spine problem is just ordinary aging. A documented timeline, and a doctor's note stating you had no neck or back pain before the shoulder injury, closes that door.
• A nexus letter from a specialist (orthopedic surgeon, spine doctor, or physiatrist), not your regular family doctor: The letter must say your condition is "at least as likely as not" (50% or greater chance) "caused by, or aggravated by," your service-connected shoulder or arm condition. It should use both words, caused AND aggravated, name the specific level shown on your MRI, and explain in one sentence how the altered posture led to the damage. Avoid a letter that says "could be related" or "may be linked," those weak words get denied.
• Proof this is a separate problem, not just more shoulder pain: VA will only add a rating for your neck or back if it limits you in ways your shoulder alone does not, less neck motion, pain bending your back, weaker grip, trouble with overhead work. Make sure your records spell out what the neck or back adds on top of the shoulder limitation.
• Ruling out other causes in writing: If you never had a prior neck or back injury, unrelated arthritis, or a family history of spine disease, have your doctor say so directly in the letter. This blocks VA's most common denial reason, "your spine damage is unrelated aging, not caused by your shoulder."

The five decisions below are Board grants of service connection for a cervical strain (or cervical spine disability) claimed as secondary to a service-connected shoulder disability with limitation of arm motion. In each case the Board found a credible link between the shoulder condition and the neck. Remember that these decisions are not binding precedent on any other veteran's claim. They simply show what evidence and reasoning succeeded in these particular records.

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.

Every item below comes from a pattern in the decisions on this pairing, not from general claim advice.

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.

1. You file the claim, naming Shoulder or Arm Limitation as the service-connected primary and back or neck strain as secondary. Directly with VA, through VA.gov, or with an accredited representative's help.
2. 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.
3. The C&P exam is conducted, usually with the examiner asked to address the specific secondary theory (causation and aggravation both).
4. 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.
5. VA issues the decision letter stating the outcome and the reasoning.
6. If denied or under-rated, you choose an appeal lane, Supplemental Claim, Higher-Level Review, or a Board appeal, covered below.

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 back or neck strain symptoms relate to your shoulder or arm limitation timeline, treatment, and any aggravation, that is the detail a nexus opinion relies on.

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.

Keep documentation of ongoing treatment, follow-up evaluations, and any updated diagnostic testing for your back or neck strain 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 back or neck strain worsens, see the Rating Increase Guide.
