A health plan operating in three California counties remains below the state’s minimum performance level, data released this month shows.

The Anthem Blue Cross Medi-Cal plan in Alameda, Contra Costa and Kings counties has consistently failed the state’s performance review since at least February 2014.

Medi-Cal is California’s low-income health plan.

The scores for the plan in the three counties appear virtually unchanged from the last report in March released by the Department of Health Care Services, which oversees Medi-Cal. The agency’s new Quarterly Dashboard Report was released June 16.

The Anthem plan in Alameda and Kings counties scored just above 30 percent, while the plan in Contra Costa scored closer to 40 percent.

Meanwhile, two plans, Kaiser Permanente in Sacramento and San Diego, scored above 90 percent. The weighted average score among all health plans was 58 percent.

In June 8 California Health Report story, Anthem spokesman Darrel Ng said he expects the plan’s scores in Alameda, Contra Costa and Kings counties to improve soon.

The low performance scores call into question whether people in those plans are receiving adequate care.
