Shoulder conditions are rated differently depending on whether the issue is ankylosis (fusion/frozen shoulder), limitation of motion, an impairment of the humerus itself (dislocation, nonunion, malunion), or an impairment of the clavicle/scapula, each has its own diagnostic code and different rating ceiling.
Ratings differ for the "major" (dominant) vs. "minor" (non-dominant) arm, using the wrong one changes the percentage. A shoulder claimed generically as "pain" instead of identifying which specific impairment applies (ankylosis vs. limitation of motion vs. humerus impairment) can end up rated under the wrong, lower-ceiling code.
| Rating | Criteria |
|---|---|
| 50 / 40% | DC 5200 — Ankylosis, unfavorable: abduction limited to 25° from side (major/minor) |
| 40 / 30% | DC 5200 — Ankylosis, intermediate between favorable and unfavorable |
| 30 / 20% | DC 5200 — Ankylosis, favorable: abduction to 60°, can reach mouth and head |
| 40 / 30% | DC 5201 — Limitation of motion: flexion/abduction limited to 25° from side |
| 30 / 20% | DC 5201 — Limitation of motion: midway between side and shoulder level (limited to 45°) |
| 20 / 20% | DC 5201 — Limitation of motion: at shoulder level (limited to 90°) |
| 80 / 70% | DC 5202 — Loss of head of humerus (flail shoulder) |
| 60 / 50% | DC 5202 — Nonunion of humerus (false flail joint) |
| 50 / 40% | DC 5202 — Fibrous union of humerus |
| 20 / 20% | DC 5203 — Dislocation, or nonunion with loose movement, of clavicle or scapula |
