| 0% | § 4.31 Zero percent evaluations. In every instance where the schedule does not provide a zero percent evaluation for a diagnostic code, a zero percent evaluation shall be assigned when the requirements for a compensable evaluation are not met. | Osteoporosis is established on DEXA and service connected, but there is no vertebral fracture and no limitation of motion of the spine or any other affected joint that reaches a compensable level. The lowest compensable rung on this ladder is 10 percent. A zero percent rating pays nothing now, but it establishes service connection and fixes the effective date any later increase runs from. |
|---|
What supports this level- DEXA scan establishing the osteoporosis diagnosis
- Imaging showing no vertebral fracture
- Spinal and joint range of motion measured and recorded, even when normal
- Repeat DEXA and imaging over time, so progression has a documented history
|
| 10% | Forward flexion of the thoracolumbar spine greater than 60 degrees but not greater than 85 degrees; or, forward flexion of the cervical spine greater than 30 degrees but not greater than 40 degrees; or, combined range of motion of the thoracolumbar spine greater than 120 degrees but not greater than 235 degrees; or, combined range of motion of the cervical spine greater than 170 degrees but not greater than 335 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. | Osteoporosis has left a joint with objectively painful motion, or with limitation of motion that is not compensable under that joint's own code. 38 CFR 4.59 makes 10 percent the minimum for the joint. A vertebral body fracture with loss of 50 percent or more of the height also reaches 10 percent on its own under the spine formula. |
|---|
What supports this level- DEXA scan showing osteoporosis (T-score of -2.5 or below)
- Objective evidence of painful motion at the affected joint
- Imaging showing a vertebral body fracture, with percentage height loss stated
- Range of motion measured for every affected joint or spinal segment
|
| 20% | Forward flexion of the thoracolumbar spine greater than 30 degrees but not greater than 60 degrees; or, forward flexion of the cervical spine greater than 15 degrees but not greater than 30 degrees; or, the combined range of motion of the thoracolumbar spine not greater than 120 degrees; or, the combined range of motion of the cervical spine not greater than 170 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. | Osteoporotic fracture residuals have left forward flexion of the thoracolumbar spine between 30 and 60 degrees, or muscle spasm or guarding severe enough to produce an abnormal gait or abnormal spinal contour such as scoliosis or abnormal kyphosis — the kyphosis of multiple vertebral compression fractures often qualifies here. |
|---|
What supports this level- DEXA scan confirming osteoporosis
- Forward flexion measured and recorded
- Abnormal spinal contour or gait documented on examination
- Imaging showing one or more vertebral compression fractures
|
| 30% | Forward flexion of the cervical spine 15 degrees or less; or, favorable ankylosis of the entire cervical spine. | Osteoporotic fractures in the CERVICAL spine have left forward flexion of the neck at 15 degrees or less, or favorable ankylosis of the entire cervical spine. This step exists only for the cervical segment — the thoracolumbar spine has no 30 percent rung on this formula. |
|---|
What supports this level- Imaging showing one or more cervical vertebral compression fractures
- Cervical forward flexion measured at 15 degrees or less
- Favorable ankylosis of the entire cervical spine documented
- Cervical and thoracolumbar segments measured separately at the same examination
|
| 40% | Unfavorable ankylosis of the entire cervical spine; or, forward flexion of the thoracolumbar spine 30 degrees or less; or, favorable ankylosis of the entire thoracolumbar spine. | Osteoporotic vertebral fractures have left forward flexion of the thoracolumbar spine at 30 degrees or less, or favorable ankylosis of the entire thoracolumbar spine. |
|---|
What supports this level- Vertebral compression fractures documented on imaging
- Forward flexion of 30 degrees or less measured
- Ankylosis of the thoracolumbar spine documented
- Significant functional limitation from bone fragility
|
| 50% | Unfavorable ankylosis of the entire thoracolumbar spine. | Osteoporotic fractures have produced unfavorable ankylosis of the entire thoracolumbar spine. There is no 60 percent rung on this formula — the next and last step is 100 percent. |
|---|
What supports this level- Multiple pathological fractures documented
- Unfavorable ankylosis of the entire thoracolumbar spine documented
- Significant height loss from vertebral fractures
- Severe functional impairment requiring assistive devices
|
| 100% | Unfavorable ankylosis of the entire spine. Note (6): Separately evaluate disability of the thoracolumbar and cervical spine segments, except when there is unfavorable ankylosis of both segments, which will be rated as a single disability. | Osteoporotic fractures have produced unfavorable ankylosis of the ENTIRE spine — cervical and thoracolumbar together. This is the only 100 percent rung the spine formula prints, and Note (6) says the two segments are rated separately except in exactly this case, where they are rated as a single disability. |
|---|
What supports this level- Imaging showing fusion of both the cervical and thoracolumbar segments
- Unfavorable ankylosis of the entire spine documented on examination
- Spine fixed in flexion or extension with one or more of the Note (5) consequences (difficulty walking from a limited line of vision, restricted mouth opening and chewing, breathing limited to diaphragmatic respiration, gastrointestinal symptoms from costal-margin pressure, dyspnea or dysphagia, atlantoaxial or cervical subluxation or dislocation, or neurologic symptoms from nerve root stretching)
- Both spine segments evaluated at the same examination
