The veteran sought service connection for varicose veins, asserting that the condition began during service and had continued since that time. The Board denied the claim after relying on a VA medical examination that concluded the disability was unrelated to service.

The Court found the VA examination inadequate because the examiner failed to meaningfully address whether the veteran’s current varicose veins were related to the observable symptoms described during and after service. The Court emphasized that once VA elects to provide a medical examination, the duty to assist requires that the examination be adequate for adjudication purposes.

The Court also discussed the competency of lay evidence. It explained that varicose veins are a condition capable of lay observation because they are visually observable and identifiable without specialized medical training. Therefore, the veteran’s testimony concerning continuity of symptoms was competent evidence that required proper consideration.

Barr became one of the foundational veterans-law cases governing adequacy of VA examinations and the competency of lay evidence concerning observable conditions.

• Once VA provides a medical examination, it must ensure the examination is adequate.
• The duty to assist includes obtaining adequate medical opinions.
• Lay evidence may be competent to establish observable symptomatology.
• Conditions capable of lay observation may be identified through competent lay testimony.
• The Board must adequately address continuity-of-symptom evidence.

Barr established that inadequate VA examinations violate the duty to assist and reinforced that veterans are competent to describe observable medical conditions and continuity of symptoms.

Barr is one of the most frequently cited examination-adequacy cases in veterans law and is foundational in challenging deficient VA medical opinions.

• Providing conclusory or incomplete medical examinations.
• Ignoring competent lay evidence.
• Failing to address continuity of symptoms.
• Relying on examinations that do not answer the relevant nexus question.
• Inadequate reasons and bases regarding lay competency.

A veteran reports visible skin symptoms continuously since service, but the VA examiner ignores the veteran’s history and provides a conclusory negative nexus opinion. Under Barr, the examination may be inadequate.

Use Barr when:
• Challenging inadequate VA examinations.
• Arguing that lay evidence establishes observable symptoms.
• Contesting medical opinions that ignore continuity reports.
• Raising duty-to-assist deficiencies.
