According to the most recent edition of The Competitive Edge HMO Industry Report released by InterStudy Publications, HMOs lost almost three million enrollees between January 1, 2001 and January 1, 2002, the largest total enrollment decrease to date. While total HMO enrollment declined over the past year, there is still a significant number of plans showing enrollment growth. Factoring in mergers, acquisitions, plan closures and the addition of new HMOs, there are 490 HMOs that were operational on January 1, 2001 and remained operational as of January 1, 2002. Of those 490 HMOs, 236 experienced increases in total HMO enrollment.
"Almost half of the HMOs operational in both 2001 and 2002 experienced increases in total HMO enrollment," said Tammy Lauer, Director of Research for InterStudy Publications. "A lot of the enrollment decrease we saw between January 2001 and January 2002 was attributable to Aetna U.S. Healthcare, which had a net enrollment decrease of 2.2 million and closed six plans."
The HMO Industry Report focuses on enrollment trends, lists the top 25 largest- and fastest-growing HMOs, analyzes sources of HMO enrollment growth and decline, and presents state-by-state enrollment information. In addition, the 12.2 version provides data related to HMO finances and premiums.
