In response to blistering criticism from a consumer group, California’s Obamacare exchange vowed to fix longstanding enrollment and tax-related errors that have blocked consumers from getting coverage for months and left some with unforeseen bills.

In the wake of the Supreme Court’s decision in King v. Burwell, President Obama has claimed that Obamacare is working and here to stay.

In truth, the actual effect of the Supreme Court’s decision leaves Obamacare unchanged, and the law is certainly not working well.

Not only will Obamacare’s current political and operational problems continue, but new ones will crop up as more provisions of the law take effect.

Starting in 2017, the Affordable Care Act will allow states to use waivers to pursue virtually any type of proposals for health care reform that they can imagine. It’s a huge opportunity for states interested in expanding or changing how health care is delivered.

But will anyone actually take advantage of it?

Thousands of Louisianians who signed up for health insurance with the Louisiana Health Cooperative were abruptly notified last month the company would discontinue all coverage in 2016. It was likely surprising news to many of the 17,000 customers who relied upon the company to help pay for their health care needs.

A daunting project to verify whether 1.2 million Medicaid enrollees qualify for the program entered its second phase this month, as tens of thousands of people with disabilities received letters telling them they need to reapply for benefits.

MassHealth, the state’s Medicaid program, needs to reach a diverse group whose limitations can be physical or mental and who will have to fill out lengthy forms to maintain their health coverage.

The Associated Press has reported that the U.S. Attorney’s office has issued subpoenas to the Massachusetts Health Connector (the state’s insurance exchange). The subpoenas cover the period during which the website experienced major technical problems and mismanagement as the state transferred to an Obamacare (ACA) exchange under former Governor Deval Patrick (D-MA).

Three Republican senators have sent a letter to the Centers for Medicare and Medicaid Services expressing concern for the “lack of oversight for more than $1 billion in federal grants” given to state-based marketplaces.

In the letter to CMS Acting Administrator Andy Slavitt, the senators — Orrin Hatch of Utah, Chuck Grassley of Iowa, and John Barrasso of Wyoming — note a handful of state-based exchanges have switched to the federal marketplace, run by CMS, and inquire if the agency will seek reimbursement for funds the states received from CMS to set up a state-based marketplace.

Bleeding cash, the Louisiana Department of Insurance (LDI) announced Friday that Louisiana’s Obamacare health insurance co-op will be closing its doors by the end of 2015.

It will be the second collapse of an Obamacare health care co-op this year and the third since the Obama administration rolled them out in 2012 as a competitor to commercial health insurance companies.

The number of Minnesotans struggling to pay their medical bills is rising sharply, despite an increase in the number of residents who have health insurance.

In the past year, Minnesota’s main hospital and clinic groups filed nearly 9,000 lawsuits against people with large or long-standing medical debts — a sharp increase since 2005, according to a Star Tribune analysis of court records.

State-run health insurance markets that offer coverage under President Barack Obama’s health law are struggling with high costs and disappointing enrollment. These challenges could lead more of them to turn over operations to the federal government or join forces with other states.
