Key takeaways

  • Holding: The Ninth Circuit affirmed the district court's order upholding the denial of disability insurance benefits, finding substantial evidence supported the administrative law judge's rejection of the claimant's medical opinion.
  • Standard: Substantial evidence standard
  • Vote: Unanimous decision by a three-judge panel without oral argument.
  • Practical effect: The decision reinforces the Ninth Circuit's standard for reviewing Social Security disability denials, emphasizing that administrative law judges must have substantial evidence to reject a treating physician's opinion based on inconsistencies and lack of objective support.

Background

Claimant Christopher George Vonovich appealed the district court’s decision affirming the Commissioner of Social Security’s denial of his application for disability insurance benefits under Title II of the Social Security Act. The appeal challenged the administrative law judge’s determination regarding the persuasiveness of medical evidence.

The court’s reasoning

The panel reviewed the district court’s order de novo and affirmed, finding that substantial evidence supported the administrative law judge’s conclusion that Dr. McDonough’s medical opinion was unpersuasive. The administrative law judge reasonably identified inconsistencies between Dr. McDonough’s opinion and the record evidence, including the claimant’s own notes and descriptions of normal activities. The court also found a lack of objective medical evidence to support Dr. McDonough’s conclusion, noting for instance that the record contained no diagnosis of anxiety despite the physician’s opinion. Additionally, the court held that Vonovich forfeited several other challenges to the agency’s decision because he did not raise them before the district court.

What it means going forward

The decision reinforces the Ninth Circuit’s standard for reviewing Social Security disability denials, emphasizing that administrative law judges must have substantial evidence to reject a treating physician’s opinion based on inconsistencies and lack of objective support.
