Shoulder Anatomy and Common Pathology
The shoulder is the most mobile joint in the body and one of the most complex. The glenohumeral joint, the acromioclavicular joint, and the sternoclavicular joint, along with the surrounding rotator cuff musculature (supraspinatus, infraspinatus, teres minor, subscapularis), labrum, and stabilizing ligaments, all contribute to its range of motion and stability. Injuries affect different components and require different evidentiary support.
Common shoulder diagnoses encountered in veterans' claims include rotator cuff tears (full-thickness or partial-thickness), rotator cuff tendinopathy, subacromial impingement, glenohumeral instability with recurrent dislocation, acromioclavicular separation or arthritis, glenohumeral osteoarthritis (often post-traumatic), labral tears (SLAP lesions, Bankart lesions), adhesive capsulitis (frozen shoulder), and post-surgical residuals.
In-Service Mechanisms for Shoulder Injury
Common in-service mechanisms include parachute landings (especially for airborne and special operations veterans), heavy load carriage producing rotator cuff microtrauma, falls from vehicles or aircraft, sports injuries during PT, motor vehicle accidents, training accidents involving direct trauma, repetitive overhead work in maintenance or aviation MOSs, and explosions or blast exposure with secondary impact.
Service treatment records may contain entries describing the acute injury or chronic complaints — sick call visits, profiles, troop medical clinic notes. When records are sparse, lay statements from fellow service members or family describing the in-service injury and the onset of symptoms can corroborate the veteran's account. A nexus letter may then articulate that the current shoulder pathology is at least as likely as not related to the documented mechanism.
Dominant vs. Non-Dominant Arm
Under 38 CFR 4.69, the dominant arm — the arm the veteran uses for fine motor tasks, writing, and primary manipulation — is rated higher than the non-dominant arm for the same level of impairment. The veteran identifies their dominant side, and the rating decision reflects that designation.
The difference matters because the dominant arm has greater functional importance for daily activities and most occupations. For example, under DC 5201 the same range-of-motion limitation produces a 40 percent rating for the dominant arm and a 30 percent rating for the non-dominant arm at the highest tier.
DC 5201 — Limitation of Arm Motion
Limitation of motion of the arm at the shoulder is one of the most commonly applied codes. Goniometric measurement of active and passive range of motion in flexion, abduction, internal rotation, and external rotation establishes the limitation. Normal flexion and abduction reach approximately 180 degrees; normal internal and external rotation reach approximately 90 degrees.
Rating Tiers (Dominant / Non-Dominant)
- 20 percent / 20 percent — Motion at shoulder level (90 degrees of flexion/abduction).
- 30 percent / 20 percent — Motion midway between side and shoulder (45 degrees).
- 40 percent / 30 percent — Motion limited to 25 degrees from the side.
The examiner should document range of motion in all four planes, observe for crepitus or guarding, perform impingement and stability testing, and characterize functional loss due to pain, weakness, fatigability, or incoordination.
DC 5202 — Impairment of the Humerus
This code addresses several specific humeral pathologies including malunion, recurrent dislocation, fibrous union, nonunion (false flail joint), and loss of the head of the humerus.
Recurrent Dislocation
- 30 percent / 20 percent — Frequent episodes and guarding of all arm movements (dominant/non-dominant).
- 20 percent / 20 percent — Infrequent episodes and guarding of movement only at shoulder level.
Malunion
- 30 percent / 20 percent — Marked deformity.
- 20 percent / 20 percent — Moderate deformity.
Fibrous Union, Nonunion, or Loss of Head
- Higher ratings up to 80 percent (dominant) / 70 percent (non-dominant) for loss of head (flail shoulder).
- Substantial intermediate ratings for fibrous union and nonunion (false flail joint).
DC 5200 — Ankylosis of Scapulohumeral Articulation
Ankylosis is a fixed or fused joint with no functional motion. DC 5200 ratings are based on the position of the ankylosis.
- Unfavorable (abduction limited to 25 degrees from side): 50 percent (dominant) / 40 percent (non-dominant).
- Intermediate (between favorable and unfavorable): 40 percent / 30 percent.
- Favorable (abduction to 60 degrees, can reach mouth and head): 30 percent / 20 percent.
DC 5203 — Impairment of Clavicle or Scapula
Conditions such as acromioclavicular separation or clavicular nonunion are rated under DC 5203:
- 20 percent — Dislocation of clavicle or scapula.
- 20 percent — Nonunion with loose movement.
- 10 percent — Nonunion without loose movement, or malunion.
Or the condition may be rated based on impairment of function of the contiguous joint (typically using DC 5201 if shoulder motion is affected).
Functional Loss and Painful Motion
The VA recognizes that the rating must reflect the actual functional limitation, not just the static measurement of motion. Under 38 CFR 4.40 and 4.45, the rater must consider:
- Pain on motion and at what point in the range of motion pain begins (DeLuca v. Brown).
- Weakness against resistance.
- Excess fatigability with repetitive use.
- Incoordination affecting the use of the joint.
- Flare-ups — periods when symptoms substantially worsen — and their estimated frequency, duration, and severity.
The C&P examination should test motion before and after repetitive use, document the point at which pain begins, and estimate functional loss during flare-ups. A medical opinion can supplement the examination by characterizing the typical functional loss based on records review.
Evidence That Strengthens a Shoulder Claim
A defensible shoulder claim typically rests on the following evidence.
Service Treatment Records
STR entries documenting the in-service injury or chronic complaints — sick call notes, profiles, troop medical clinic visits, and separation examination findings.
Imaging Studies
X-ray reports establishing degenerative change, fracture, or AC joint pathology. MRI reports characterizing rotator cuff, labral, or cartilage pathology. Imaging anchors the structural diagnosis.
Operative Reports
Notes from arthroscopic or open shoulder surgery describing intra-operative findings — extent of rotator cuff tear, labral pathology, cartilage condition.
Range-of-Motion Documentation
Goniometric measurements over time showing the chronicity and progression of motion limitation.
Clinical Examination Findings
Impingement signs (Neer, Hawkins-Kennedy), instability tests (apprehension, relocation), strength testing, and crepitus or guarding observations.
Functional Documentation
Statements from the veteran, spouse, or coworkers describing what the veteran can and cannot do with the affected arm — overhead reaching, carrying weight, sleeping on the affected side, dressing, performing occupational tasks.
Medical Nexus Opinion
A physician's opinion when service connection is contested — particularly when STRs are sparse — articulating that the current shoulder pathology is at least as likely as not related to the in-service mechanism. The opinion should reference the relevant clinical literature on the natural history of similar injuries.
Frequently Asked Questions
The VA rates shoulder conditions under 38 CFR 4.71a using several diagnostic codes — primarily DC 5200 (ankylosis of scapulohumeral articulation), DC 5201 (limitation of arm motion), DC 5202 (impairment of the humerus including malunion, recurrent dislocation, fibrous union, nonunion, or loss of head), and DC 5203 (impairment of the clavicle or scapula). Ratings differ between the dominant (major) and non-dominant (minor) arm, with the dominant arm typically receiving higher ratings for the same level of impairment.
Under 38 CFR 4.69, only one arm is considered dominant. The dominant arm — typically the right arm for right-handed individuals and the left arm for left-handed individuals — receives higher ratings for the same level of impairment because it has greater functional importance. Veterans must self-identify their dominant side, and the rating decision must reflect that designation.
Shoulder range of motion is measured goniometrically. Normal flexion and abduction reach approximately 180 degrees. Under DC 5201, ratings are 20 percent (motion at shoulder level for non-dominant) or higher tier ratings for motion midway between side and shoulder, or motion limited to 25 degrees from the side. The examiner must document active and passive range of motion in flexion, abduction, internal rotation, and external rotation, and consider functional loss due to pain, weakness, fatigability, or incoordination.
Strong evidence includes service treatment records documenting the in-service injury or onset of symptoms, post-service medical records showing chronicity, imaging studies (X-ray, MRI) characterizing structural pathology, operative reports if surgery was performed, range-of-motion measurements over time, clinical examination findings (impingement signs, instability tests, strength testing), and a medical nexus opinion when service connection is contested. Documentation of functional loss — what the veteran can and cannot do with the affected arm — supports the rating analysis.
