The American College of Radiology is urging the Biden administration to fix holes in a recent ban of “surprise” medical bills for out-of-network care.

ACR said it supports the No Surprises Act, authorized as part of year-end legislation in December, and its goals to keep patients out of reimbursement disputes, and address the adequacy of payment networks. However, the college is concerned gray areas give health insurers leeway “that could be used as leverage to disrupt good-faith negotiations.”

“While the intent of the NSA is clear — to end surprise billing while preserving access to care — there are a number of policies in the act that require further clarification through rule-making,” ACR leadership wrote in a May 11 letter to new Health and Human Services Secretary Xavier Becerra.

The college asked for insight into how HHS will qualify provider payment amounts for the No Surprises Act, meld these changes with state laws, and steer independent arbitrators resolving physician-insurer disagreements. CEO William Thorwarth Jr. also emphasized that “most of radiology is practiced in-network,” noting that the specialty has accounted for only 1% of payment disputes under New York state’s long-running local surprise-billing legislation.

“The ACR believes that fair payment mechanisms are necessary to ensure adequate reimbursement for out-of-network services in order to support a sustainable healthcare system,” he wrote. “By promoting good faith negotiations between payers and providers, and including mechanisms that promote network contracting, the [No Surprises Act} represents a reasonable solution to this issue.”
