WASHINGTON—Utilization of albuterol and levalbuterol shifted as payments changed for the inhalation drugs, according to an HHS Office of Inspector General report.
 
Released Sept. 2 (the same day as the OIG's August report on power wheelchair payments), the report was conducted to determine whether shifts in utilization for the drugs coincided with changes in Medicare payment and coding policy. The short answer is yes, the OIG said.
 
In 2003 and 2004, albuterol and levalbuterol were included in the same payment code and had the same Medicare payment amount based on the average wholesale price of the drugs, used primarily to treat asthma and COPD. In those years, the OIG said, Medicare reimbursement favored albuterol, and nearly all beneficiaries (97 percent) received that drug.
 
“Specifically, in the fourth quarter of 2004, Medicare paid suppliers an average of almost five times more than their cost for albuterol, but significantly less than their cost for levalbuterol,” the report said.  
 
But when payment and coding changes in 2005 resulted in higher reimbursements for levalbuterol than for albuterol, the report found a quarter of beneficiaries who had been prescribed albuterol in 2004 were switched to levalbuterol between 2005 and 2007.
 
And in 2007 when CMS changed the reimbursement policy again—to a single payment amount for both drugs based on average sale price—“suppliers were being reimbursed at almost 10 times their cost for albuterol, but roughly half their cost for levalbuterol,” the OIG found. “After this payment and coding change, two-thirds of the beneficiaries in our sample who received levalbuterol as of June 2007 were changed to albuterol.”
 
As a result, the OIG cautioned, when Congress and CMS make coding and reimbursement decisions, “it is important they take into consideration that the new policies may affect what drug a beneficiary is prescribed.” In some cases, the report continued, “this may limit access to a potentially more effective product; in others, utilization could be driven toward a more expensive product that offers no clinical advantage.”
 
The OIG said it would continue to monitor utilization and payment for these and other drugs to identify inappropriate payments.
 
Responding to the report, CMS said it was aware that changes to coding and payment policies could affect access to drugs. However, the agency noted, in the case of albuterol and levalbuterol, the changes were not discretionary but instead were mandated under the Medicare Modernization Act.
 
CMS suggested the OIG further study cases in which doctors reportedly were unaware of medication changes for their patients and where doctors used clinical rationales for switching patients to a different drug.
