$136 for a $2 bag of saline? Anthem, MaineHealth trade blame in billing disputes

Apr. 17—An IV bag of saline costs Maine Medical Center $2, but the Portland hospital has charged patients covered by Anthem insurance a total of $136 per bag and also tried to hide the bill, according to Anthem.

Anthem, on the other hand, refuses to pay Maine Medical Center for multiple procedures performed on one patient in the same day, according to the hospital's parent, MaineHealth. So when a heart patient recently needed two stents, Anthem would pay for only one, the hospital network alleges.

Anthem, the state's largest insurer, and MaineHealth, the state's biggest health care network, provided the Press Herald with those and other examples of billing issues they say have added up to millions of dollars in overcharges and underpayments.

The unusual public accusations and details open a rare window on the health care industry's behind-the-scenes clashes over medical costs and insurance coverage. Medical billing is a notoriously confusing and complex system, with charges that can vary widely for the same procedures. And it's a system that is opaque for most consumers.

The feud became public this month when MaineHealth announced that Maine Medical Center, the state's largest hospital, would leave Anthem's insurance network next January, a decision that would force thousands of patients to pay far higher costs for out-of-network care. MaineHealth said it announced the move because Anthem was shortchanging Maine Med $1 million per month in medication reimbursements while also accusing the insurance company of slow processing and routine denials of $70 million in payments across the health care network.

Anthem has faced similar allegations in other states. Two California hospitals threatened to leave the insurer last year over the same issues but ultimately settled, and Georgia fined Anthem $5 million in March for the way it was paying claims.

If the dispute here can't be resolved, it could affect at least 300,000 Maine patients who have Anthem insurance coverage — about 54 percent of the state's market, according to the Maine Bureau of Insurance. Maine Med's break with Anthem also could disrupt the state's entire health insurance system by forcing large-scale shifts to other carriers. The potential impacts prompted Gov. Janet Mills to urge both sides to settle the dispute.

But they appear to be far apart.

Anthem officials said a major reason an agreement is so far out of reach is that MaineHealth is overcharging for patient care. They provided the Press Herald with partially redacted medical claims to support the accusation, including two claims that show Maine Med charged $136 for $2 worth of saline — 50 milliliters of saltwater routinely used in IV bags as a vehicle to deliver medicine to patients in hospitals. All patient information was redacted from the claims.
