Drug pricing, a key issue in the federal investigation of Valeant Pharmaceuticals International Inc., has been a frequent focus of federal prosecutions and whistleblower lawsuits in recent years.

Pharmaceutical companies have paid more than $3 billion in fines to resolve pricing cases over the past decade, according to Patrick Burns, co-director of Taxpayers Against Fraud, a group that promotes whistleblowing.

Valeant said late Wednesday that it had received subpoenas from U.S. attorneys' offices in Manhattan and Boston seeking materials on a range of matters, including the financial aid it gives patients to pay for out-of-pocket costs as well as the pricing of its drugs. The company said it plans to cooperate with the investigation.

The news sent Valeant shares down 4.8% to $168.87 on Thursday. Valeant has lost more than a third of its value since its shares peaked at $262.52 in early August, partly on worries about scrutiny of its drug-price increases.

Valeant said Thursday that it "has been shifting away from transactions that are dependent on price increases in order to meet our internal target returns" and that it doesn't boost prices on the "vast majority of the thousands of" company products.

Democrats in Congress have asked Valeant to provide information about steep price increases by the company for two drugs that were featured in an April article in The Wall Street Journal. In response to one such request from Sen. Claire McCaskill of Missouri, Valeant said Wednesday that the price increases had no effect on patient access and little impact on most hospital budgets and Valeant's revenues.

It isn't clear what specific information federal prosecutors are seeking about Valeant's pricing. But past probes highlight some key ways that drug makers can run afoul of the law, in particular in the way they charge Medicare and Medicaid.

Among the biggest settlements was the more than $650 million that Merck & Co. agreed in 2008 to pay to settle allegations that it, in part, failed to give the federal Medicaid health-insurance program the same levels of rebates it gave other customers for drugs including cholesterol pill Zocor and the now-withdrawn painkiller Vioxx. Merck said at the time that it had long since taken the initiative to enhance its compliance program, and that the pricing allegations resulted from differing interpretations of Medicaid rules.

Generally in such cases, "the legal issue would be whether or not they are giving the best price to Medicaid," says Michael Mustokoff, a partner at the law firm Duane Morris who has both defended and prosecuted drug companies.

Federal law requires drug companies give Medicaid the best price for a drug offered to any customers except charitable organizations.

Other drug-pricing cases involved allegations that Medicare and other government health-insurance programs have paid more than they should have because companies inflated costs when reporting their prices to the federal government.

In 2010, Abbott Laboratories Inc., Roxane Laboratories Inc. and B. Braun Medical Inc. agreed to pay $421 million to settle U.S. government claims they each reported false prices for various drugs including the antibiotic vancomycin to get larger Medicare or Medicaid reimbursements. The companies didn't admit any wrongdoing, and said they had settled in order to avoid the expense of litigation.

There are several drug-pricing investigations now under way. Pfizer Inc. is fighting a Justice Department lawsuit accusing the company's Wyeth unit of overcharging Medicaid by hundreds of millions of dollars for heartburn drug Protonix. Pfizer said the government's allegations have no merit.

The federal government has taken some steps to prevent overcharging. For instance, it has altered the formula companies must use to determine the drug prices they report to Medicare for reimbursement decisions.

Yet when it comes to drug pricing, "there's still potential for wrongdoing in the area, and it has not gone away," says Patrick O'Connell, a former Texas assistant attorney general who prosecuted drug-pricing cases and now represents drug-company whistleblowers.

Manufacturer-supported patient-assistance programs also can potentially run afoul of federal rules. Federal law considers it to be an illegal kickback if a company gives financial help to Medicare patients so they can pay the out-of-pocket costs of their prescriptions.

"We are concerned about the use of cost-sharing subsidies to shield beneficiaries from the economic effects of drug pricing, thus eliminating a market safeguard against inflated prices," the Health and Human Services Department's office of inspector general said in a 2005 bulletin, before Medicare's Part D drug-benefits program went into effect.

To help Medicare patients fill their prescriptions, Valeant and other drug companies have contributed funds to independent charities, which then subsidize the out-of-pocket costs.

Such donations are legal. Last year, however, the inspector general issued another bulletin saying a drug maker could be violating the federal law against kickbacks if it made donations to "induce" a charity to steer patients toward the company's drugs.

In another continuing case, federal prosecutors allege in a complaint that Novartis AG "paid kickbacks…under the guise of performance rebates" to a Missouri pharmacy that served kidney-transplant patients who received patient assistance and, in exchange, the pharmacy recommended use of the Novartis drug Myfortic.

Novartis said it contracted with a number of pharmacies, which were eligible to receive rebates in connection with dispensing Myfortic, but it was up to doctors to decide which drug a patient received.

In the letter sent Wednesday to Sen. McCaskill about its drugs Isuprel and Nitropress, Valeant said it spent $544 million on patient assistance last year and expects to spend another $630 million this year. Valeant also said it had raised the list prices of Isuprel and Nitropress "to ensure that the prices reflected the value of the drugs to hospitals and patients."

Sen. McCaskill said she wasn't satisfied by Valeant's response. "Valeant has been anything but responsive or transparent—it refused to take any action until served with federal subpoenas, and it is still refusing to provide answers to many of the questions I've asked," she said in a statement.

She said she planned to keep investigating drug pricing and Valeant's response.
