Circuit Court of Appeals said the law adopted last year by Westchester County, New York, was valid under a 2000 Supreme Court ruling that rejected a challenge to a similar law in Colorado.
The court said it was bound to follow that ruling unless the Supreme Court expressly overturns it.
The Supreme Court in a 2014 case struck down a Massachusetts law establishing a 35-foot buffer zone around abortion clinics, but the court did not mention the Hill decision.
Last year, an Ohio-based U.S. appeals court temporarily blocked a Kentucky county's 10-foot buffer zone, citing the 2014 Supreme Court decision.
A Philadelphia-based appeals court is currently considering a challenge to a 20-foot buffer zone adopted by Harrisburg, Pennsylvania.
