                  HEALTHSPRING CLARIFIES PART D ENROLLMENT DATA


NASHVILLE, Tenn. (May 1, 2006) - In response to the posting by the Centers for
Medicare and Medicaid Services ("CMS") of Part D enrollment data, HealthSpring,
Inc. (NYSE:HS) is releasing its Medicare Advantage (including Part D) membership
enrollment data in order to clarify potential investor misinterpretations of the
CMS data. Please note that CMS's data relates to Part D enrollment only (in
other words, it does not reflect Medicare Advantage-only membership) as of April
27, 2006 and does not reflect the ongoing enrollment reconciliation process. For
these and other reasons, CMS has acknowledged that its published data may be
different from Medicare Advantage plans' internal counts as of any particular
date, including HealthSpring's.

         According to HealthSpring's current internal enrollment data, as of
March 31, 2006 membership in all of its Medicare Advantage plans was as follows:

                                 
                     MA-only                                   4,319
                     MA-PD                                    99,787
                                                           ---------
                         Total                               104,106(a)

                     Stand-alone PDP                          74,985(b)



                     


(a) Includes approximately 2,000 members HealthSpring is attempting to
    reconcile to CMS records.

(b) Does not include additional members auto-assigned after March 31, 2006,
    effective May 1, 2006.
