WASHINGTON—Medicare codes for oncology services have been in transition over the past few years, and oncologists are dealing with more changes now as Medicare moves from the temporary G-codes used in 2005 to cover administration of chemotherapy and other services to the permanent Current Procedural Terminology or CPT codes, which kicked in this year.

Reimbursements Lowered

Overall, changes in the codes have not had the optimal result for office-based oncologists, said Roberta Buell, MBA, vice president of provider services and reimbursement for P4 Healthcare, Columbia, Maryland, and a consultant in oncology reimbursement.

Speaking at the Community Oncology Alliance's annual meeting, Ms. Buell told the audience that the new Medicare coding changes have lowered reimbursements substantially for oncologists from those obtained with the transitional payment rate in 2004.

"I want to talk about why coding may be a rip-off, if you expect that coding would make up the 32% in the transitional drug administration rates from 2004," she said. "We all have to be careful right this minute. We should not let private payers go down the same road Medicare did."

In 2006, an important general principle for oncologists is that only one initial code is allowed per day, Ms. Buell said. Before and after infusions and pushes must always be categorized as sequential or concurrent to sequential. One concurrent code per day can be billed.

Any infusion of 15 minutes or less must be coded as a push—a rule that affects reimbursement for the administration of many supportive drugs, she pointed out. What's more, following each infusion's initial hour, the time spent must be more than 30 minutes to be coded and billed, another rule that may lower reimbursements.

The overall impact of the drug administration coding changes since 2004 has been significant, with many protocols having reimbursement decreases of 20% to 30% and some as much as 54%, Ms. Buell said.
