The availability of managed care benefits for the treatment of sexual dysfu
nction is inextricably linked with cost. An atypically low increase of 4.4%
in aggregate healthcare expenditures in 1995-1996 stands in sharp contrast
to outlays of more than 11% between 1966 and 1993. Between 1993 ana 1996,
that increase hovered at about 5%, the result largely of the growth of mana
ged care and low levels of general inflation. However, despite relative con
tainment of overall healthcare expenditures, those related to pharmaceutica
ls have risen more than 9.2% annually, an increase that reflects the manage
d care industry's failure to restrain drug costs. In deciding whether it wi
ll cover a particular treatment, the managed care industry applies three se
ts of criteria relating to efficacy, medical necessity, and appropriateness
. Managed care companies are expected to counter runaway pharmacy costs for
sildenafil by excluding it from coverage, imposing significant limitations
, or requiring higher copayments.
