But now, many doctors, their medical associations and members of Congress are crying foul, arguing the rule released by the Biden administration in September for implementing the law favors insurers and doesn't follow the spirit of the legislation.

"The Administration's recently proposed regulation to begin implementing the law does not uphold Congressional intent and could incentivize insurance companies to set artificially low payment rates, which would narrow provider networks and potentially force small practices to close, thus limiting patients' access to care," Rep. Larry Bucshon, R-Ind., who is a doctor and helped spearhead a letter of complaint this month, told us in a written statement. //

Nearly half of the 152 lawmakers who signed that letter were Democrats, and many of the physicians serving in the House signed. //

The provisions in the new rule "do not reflect the way the law was written, do not reflect a policy that could have passed Congress, and do not create a balanced process to settle payment disputes," the lawmakers told administration officials in the letter.
