VA Disability Rating for Thoracic Spine: Codes, Range of Motion, and Evidence (2026)

What Counts as a Thoracic Spine Condition

The thoracic spine is the twelve-vertebra segment between the cervical and lumbar spine. Common ratable thoracic spine conditions in veterans include degenerative disc disease, intervertebral disc syndrome (IVDS), compression fractures (frequently the result of blast exposure, falls, or motor vehicle accidents), Scheuermann disease aggravated by service, ankylosing spondylitis, post-surgical fusion changes, and chronic thoracic strain.

Thoracic spine conditions present with mid-back pain (often with a band-like distribution), thoracic radiculopathy producing chest wall or abdominal pain, restricted thoracic rotation and flexion, stiffness, and - in severe disc pathology - myelopathic findings.

The General Rating Formula for the Spine

All thoracolumbar spine conditions other than IVDS rated under DC 5243's incapacitating episodes formula use the General Rating Formula. The percentage is based on the worst of the listed criteria.

10 Percent

Forward flexion of the thoracolumbar spine greater than 60 degrees but not greater than 85 degrees; OR combined range of motion of the thoracolumbar spine greater than 120 degrees but not greater than 235 degrees; OR muscle spasm, guarding, or localized tenderness not resulting in abnormal gait or abnormal spinal contour; OR vertebral body fracture with loss of 50 percent or more of the height.

20 Percent

Forward flexion of the thoracolumbar spine greater than 30 degrees but not greater than 60 degrees; OR combined range of motion of the thoracolumbar spine not greater than 120 degrees; OR muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spinal contour such as scoliosis, reversed lordosis, or abnormal kyphosis.

40 Percent

Forward flexion of the thoracolumbar spine 30 degrees or less; OR favorable ankylosis of the entire thoracolumbar spine.

50 Percent

Unfavorable ankylosis of the entire thoracolumbar spine.

100 Percent

Unfavorable ankylosis of the entire spine.

Combined Range of Motion

Combined range of motion is the sum of the ranges of forward flexion, extension, left and right lateral flexion, and left and right rotation. The normal combined range of motion for the thoracolumbar spine is 240 degrees (90 flexion + 30 extension + 30 left lateral + 30 right lateral + 30 left rotation + 30 right rotation).

Intervertebral Disc Syndrome (DC 5243)

IVDS can be rated either under the General Rating Formula (range of motion) or under the IVDS Incapacitating Episodes formula, whichever results in the higher evaluation.

Incapacitating Episodes Formula

An incapacitating episode is defined as a period of acute signs and symptoms due to IVDS that requires bed rest prescribed by a physician and treatment by a physician. The rating tiers are 10 percent (at least one week but less than two weeks during the past 12 months), 20 percent (at least two weeks but less than four weeks), 40 percent (at least four weeks but less than six weeks), and 60 percent (at least six weeks).

Why Documentation Matters

To rate under the incapacitating episodes formula, the veteran needs treatment records documenting both the physician-prescribed bed rest and physician-administered treatment for each episode. Self-reported bed rest is not sufficient. Veterans whose IVDS produces frequent flares should obtain contemporaneous documentation from each provider visit.

Separate Rating for Radiculopathy

Note 1 to the General Rating Formula directs the rater to evaluate any associated objective neurologic abnormalities, including but not limited to bowel or bladder impairment, separately under an appropriate diagnostic code.

Thoracic Radiculopathy

Thoracic radiculopathy typically produces chest wall, intercostal, or abdominal pain following a dermatomal pattern. It is rated under the Diseases of the Peripheral Nerves table at 38 CFR 4.124a, typically under DC 8520 or by analogy depending on the predominant nerve distribution.

Lower Extremity Radiculopathy from Thoracolumbar Disease

Lower extremity radiculopathy (sciatica, femoral neuropathy) arising from thoracolumbar pathology is rated separately under DC 8520 (sciatic nerve) or DC 8526 (femoral nerve), each at mild, moderate, moderately severe, or severe incomplete paralysis, or complete paralysis.

Bowel and Bladder Impairment

When thoracolumbar pathology causes bowel or bladder impairment, those manifestations are rated separately under the genitourinary or digestive codes.

DeLuca Factors and Functional Loss

The DeLuca v. Brown ruling and 38 CFR 4.40 and 4.45 require rating boards to consider functional loss due to pain, weakness, excess fatigability, incoordination, and pain on repetitive use. The C&P examiner is expected to document range of motion after three repetitions and assess whether range of motion further decreases on repetitive testing or during flare-ups.

Examinations that capture range of motion only at baseline, without addressing repetitive use or flare-ups, may understate the true functional loss. Veterans should ensure their treating providers document range of motion during active flares and the functional limitations they produce.

Service Connection Pathways

Thoracic spine conditions are claimed through several pathways.

Direct Service Connection

Veterans with documented in-service thoracic spine injury (motor vehicle accident, parachute landing, blast exposure, fall) can establish direct service connection with a current diagnosis and a medical nexus.

Secondary to Cervical or Lumbar Spine

Thoracic spine pathology can develop secondary to a service-connected cervical or lumbar spine condition through altered biomechanics, compensatory movement patterns, and adjacent-segment degeneration. The secondary pathway is 38 CFR 3.310.

Secondary to Lower Extremity Conditions

Service-connected lower extremity conditions that produce an antalgic gait (knee, hip, ankle, foot) can secondarily aggravate the thoracolumbar spine over time through altered biomechanics.

Compression Fracture from Service Trauma

Compression fractures sustained during service - whether immediately symptomatic or later identified on imaging - can support direct service connection with the matching imaging and a nexus opinion linking the fracture to the documented in-service event.

Evidence That Strengthens the Claim

Strong thoracic spine claims include the following.

Imaging

Thoracic spine X-rays document degenerative changes, compression fractures, and alignment. Thoracic MRI demonstrates disc pathology, nerve root compression, spinal cord compression, and soft tissue findings. CT is useful for assessing fracture morphology.

Range-of-Motion Documentation

Goniometer-based measurements of forward flexion, extension, lateral flexion, and rotation by a treating provider or C&P examiner. Documentation should include range of motion after three repetitions and during flare-ups.

Treatment Records

Records of conservative management (physical therapy, anti-inflammatory medication, neuromodulating medication, lifestyle modification), interventional management (thoracic facet injections, epidural steroid injections, medial branch blocks, radiofrequency ablation), or surgical management.

Incapacitating Episode Documentation

For IVDS claims under the incapacitating episodes formula, contemporaneous physician notes documenting prescribed bed rest and physician-administered treatment for each episode.

Functional Impact Statements

Statements from the veteran, family, and employers documenting the impact on routine activity, work, and recreation.

Nexus Opinion

A medical opinion that it is at least as likely as not (50 percent probability or greater) that the thoracic spine condition is related to service or to a service-connected condition.

Common Rating Issues

Several recurring issues affect thoracic spine claims.

Thoracic-Only vs Thoracolumbar Measurement

The rating board uses the combined thoracolumbar range-of-motion measurement, not the thoracic segment alone. A purely thoracic limitation with normal lumbar motion may produce a smaller measured deficit than the veteran's symptoms suggest. Examinations should document the entire thoracolumbar range with positions and segmental contributions noted.

Missed Radiculopathy

Thoracic radiculopathy is commonly missed because the chest wall or abdominal pain it produces is attributed to non-neurological causes. Veterans with band-like or dermatomal mid-back, chest wall, or abdominal pain should be evaluated for thoracic radiculopathy and have any neurological abnormalities rated separately.

Underestimating Compression Fracture

Vertebral body fractures with loss of 50 percent or more of the height qualify for a 10 percent rating under the General Rating Formula on the basis of the fracture alone. This rating is in addition to any rating based on range of motion or incapacitating episodes.

Incapacitating Episodes Without Documentation

Without physician-documented bed rest and physician-administered treatment, episodes cannot be rated under the incapacitating episodes formula. Veterans should obtain matching documentation at the time of each flare.

Related Ratable Conditions

Thoracic spine conditions frequently co-exist with other ratable conditions.

Cervical Spine

The cervical spine is rated separately under its own General Rating Formula table at 38 CFR 4.71a.

Lumbar Spine

The lumbar spine is rated as part of the same thoracolumbar segment, with one combined range-of-motion measurement covering both thoracic and lumbar contributions.

Radiculopathy

Radiculopathy in any distribution arising from thoracolumbar pathology is rated separately under the Diseases of the Peripheral Nerves table.

Scarring and Surgical Residuals

Post-surgical scars, hardware-related complications, and adjacent-segment changes after thoracic fusion are rated separately when each produces a ratable manifestation.
