Last spring, an advisory panel for the Center for Medicare and Medicaid Services (CMS) recommended that Medicare not cover low-dose CT scans for smokers or former smokers. These scans can double the proportion of lung cancers found at an early stage, while they are still treatable. Yesterday, CMS announced that it would cover the cost of these scans for people between the ages of 55 and 74 who smoke, or who quit within the last 15 years, and who have a smoking history of 30 pack-years. (That means a pack a day for 30 years, two packs a day for 15 years, etc.) The new Medicare plan would cover scans for an estimated 4 million older Americans, at a cost estimated to be more than $9 billion over five years. In a wise addition, Medicare will require smokers to get counseling on quitting or the importance of staying smoke-free before having the annual scan.
Proposed recommendations from the influential U.S. Preventive Services Task Force call for annual CT scans for some current and former smokers. Implementing these recommendations could prevent an estimated 20,000 deaths per year from lung cancer. The task force suggests annual testing for men and women between the ages of 55 and 79 years who smoked a pack of cigarettes a day for 30 years or the equivalent, such as two packs a day for 15 years or three packs a day for 10 years. This includes current smokers and those who quit within the previous 15 years. According to the draft recommendations, which were published today in the Annals of Internal Medicine, the benefits of annual checks in this group outweighs the risks. According to the Task Force recommendations, not all smokers or former smokers should undergo yearly CT scans. This group includes smokers or former smokers who are younger than 55 or older than 79, who smoked less or less often than a pack of cigarettes a day for 30 years or the equivalent, who quit smoking 15 or more years ago, or who are too sick or frail to undergo treatment for lung cancer. These draft recommendations have been posted for public comment until August 26, 2013.
