WASHINGTON — A federal judge in California on Wednesday denied a request from 19 attorneys general across the country to force the Trump administration to resume funding of cost-sharing payments under the Affordable Care Act.

The ruling leaves intact President Trump’s decision earlier this month to immediately end the payments that reimburse insurers for discounts the law requires them to give lower-income customers with health plans through ACA marketplaces.

In his decision, Judge Vince Chhabria of the US District Court for the Northern District of California wrote that resuming the payments to insurers ‘‘would be counterproductive.’’

Chhabria pointed out that most states’ insurances regulators had already prepared for a possible end to the money, by allowing companies to charge higher rates for the coming year.

The court ruling was one of several developments related to the health-care law on Wednesday. It coincided with a review by the internal watchdog for the Health and Human Services Department of one of the administration’s first actions on the law, as well as a forecast by Congress’s budget analysts of the effects of a bipartisan Senate plan to try to stabilize the ACA’s marketplaces.

According to the HHS inspector general, hours after they were briefed on outreach activities for the final days of the last Affordable Care Act enrollment season, temporary political appointees at the department abruptly canceled those plans without assessing the impact.

Meanwhile, the Congressional Budget Office found that proposed bipartisan Senate legislation would lower the federal deficit by nearly $3.8 billion during the next decade and would not affect the number of people with health insurance.
