VA Disability Rating for Ulna Impairment
Diagnostic Code 5211 · 38 CFR §4.71a
What Is It?
DC 5211 covers impairments of the ulna bone, which is the larger of the two forearm bones on the pinky finger side. Impairments include nonunion of the ulna where a fracture fails to heal, and malunion where it heals in a poor position. The severity depends on whether there is false movement and loss of bone substance. Nonunion in the upper half of the ulna is generally more disabling because it affects elbow stability. Veterans may develop ulna impairments from forearm fractures during training, falls, vehicle accidents, or direct blows to the forearm during service.
Rating Criteria
| Rating | Criteria |
|---|---|
| 40% | Nonunion in the upper half of the ulna in the dominant arm with false movement and loss of bone substance |
| 30% | Nonunion in the upper half of the ulna in the non-dominant arm, or nonunion in the lower half of the dominant arm |
| 20% | Nonunion in the lower half of the ulna in the non-dominant arm |
| 10% | Malunion of the ulna with bad alignment |
Evidence Needed
- Imaging showing ulna nonunion or malunion
- Medical records from the original fracture during service
- Physical exam documenting instability or false movement
- Range of motion testing of the elbow and wrist
- Documentation of dominant arm
C&P Exam Tips
- Show the examiner imaging documenting the ulna impairment
- Demonstrate any false movement at the nonunion site
- Describe how the impairment affects your ability to grip, lift, and rotate the forearm
- Point out any visible deformity in the forearm
- Document your dominant arm
How to File
File under DC 5211 for ulna impairment. Specify whether the impairment is nonunion or malunion, and in which half of the bone. Include imaging and indicate your dominant arm, as all ratings under this code differ by dominance.
Common Mistakes
Not specifying which half of the ulna is affected Failing to document false movement at the nonunion site Not noting dominant arm status Missing associated ulnar nerve damage from the fracture
Frequently Asked Questions
Why does location on the ulna matter?
The upper half of the ulna forms part of the elbow joint, so nonunion there affects both elbow stability and forearm function, making it more disabling than lower half nonunion, which primarily affects the wrist area.
What is false movement?
False movement means there is abnormal motion at the fracture site because the bone ends are not connected. The forearm bends or shifts where it should be rigid. This is a sign of nonunion and indicates significant structural failure.
