Group II.Depression of arm from vertical overhead to hanging at side (1, 2); downward rotation of scapula (3, 4); 1 and 2 act with Group III in forward and backward swing of arm. Function: Extrinsic muscles of shoulder girdle: (1) Pectoralis major II (costosternal); (2) latissimus dorsi and teres major (teres major, although technically an intrinsic muscle, is included with latissimus dorsi); (3) pectoralis minor; (4) rhomboid

The VA rates Group II.Depression of arm from vertical overhead to hanging at side (1, 2); downward rotation of scapula (3, 4); 1 and 2 act with Group III in forward and backward swing of arm. Function: Extrinsic muscles of shoulder girdle: (1) Pectoralis major II (costosternal); (2) latissimus dorsi and teres major (teres major, although technically an intrinsic muscle, is included with latissimus dorsi); (3) pectoralis minor; (4) rhomboid under Diagnostic Code 5302 at 0%, 20%, 30%, 40%. The minimum 0% rating requires: Slight; 0. The maximum 40% rating requires: Severe; 30.

The VA rates Group II.Depression of arm from vertical overhead to hanging at side (1, 2); downward rotation of scapula (3, 4); 1 and 2 act with Group III in forward and backward swing of arm. Function: Extrinsic muscles of shoulder girdle: (1) Pectoralis major II (costosternal); (2) latissimus dorsi and teres major (teres major, although technically an intrinsic muscle, is included with latissimus dorsi); (3) pectoralis minor; (4) rhomboid under Diagnostic Code (DC) 5302, governed by 38 CFR 38 CFR § 4.73. The diagnostic code establishes the specific rating tiers and severity criteria the VA examiner applies.

A 0% rating requires: Slight; 0. A 40% rating requires: Severe; 30. The difference typically reflects the frequency, severity, or functional impact of the condition as documented in medical records and C&P examination findings.

Veterans rated for Group II.Depression of arm from vertical overhead to hanging at side (1, 2); downward rotation of scapula (3, 4); 1 and 2 act with Group III in forward and backward swing of arm. Function: Extrinsic muscles of shoulder girdle: (1) Pectoralis major II (costosternal); (2) latissimus dorsi and teres major (teres major, although technically an intrinsic muscle, is included with latissimus dorsi); (3) pectoralis minor; (4) rhomboid may qualify for TDIU if the condition — alone or in combination with other service-connected disabilities — prevents substantially gainful employment. A single disability rated at 60% or higher (or multiple disabilities combining to 70%, with one at 40%) can support a TDIU claim under 38 CFR § 4.16.

Service connection for Group II.Depression of arm from vertical overhead to hanging at side (1, 2); downward rotation of scapula (3, 4); 1 and 2 act with Group III in forward and backward swing of arm. Function: Extrinsic muscles of shoulder girdle: (1) Pectoralis major II (costosternal); (2) latissimus dorsi and teres major (teres major, although technically an intrinsic muscle, is included with latissimus dorsi); (3) pectoralis minor; (4) rhomboid requires three elements: (1) a current diagnosis of the condition, (2) an in-service event, injury, or disease, and (3) a medical nexus linking the current diagnosis to that in-service occurrence. A nexus letter from a treating or independent medical examiner is the most reliable nexus evidence.

A Compensation & Pension (C&P) exam for Group II.Depression of arm from vertical overhead to hanging at side (1, 2); downward rotation of scapula (3, 4); 1 and 2 act with Group III in forward and backward swing of arm. Function: Extrinsic muscles of shoulder girdle: (1) Pectoralis major II (costosternal); (2) latissimus dorsi and teres major (teres major, although technically an intrinsic muscle, is included with latissimus dorsi); (3) pectoralis minor; (4) rhomboid uses a Disability Benefits Questionnaire (DBQ) specific to the body system involved. The examiner documents the frequency, severity, and functional impact of your symptoms. Bring all relevant treatment records and be prepared to describe your worst-day symptoms — the examiner rates your condition based on the full clinical picture, not a single visit.
