8. Medical Costs and Medical Costs Payable
Medical costs and medical costs payable include estimates of our obligations for medical care services that have
been rendered on behalf of insured consumers but for which we have either not yet received or processed claims,
and for liabilities for physician, hospital and other medical cost disputes. We develop estimates for medical costs
incurred but not reported using an actuarial process that is consistently applied, centrally controlled and
automated. The actuarial models consider factors such as time from date of service to claim receipt, claim
backlogs, care provider contract rate changes, medical care consumption and other medical cost trends. We
estimate liabilities for physician, hospital and other medical cost disputes based upon an analysis of potential
outcomes, assuming a combination of litigation and settlement strategies. Each period, we re-examine previously
established medical costs payable estimates based on actual claim submissions and other changes in facts and
circumstances. As the liability estimates recorded in prior periods become more exact, we adjust the amount of
the estimates, and include the changes in estimates in medical costs in the period in which the change is
identified. For example, in every reporting period our operating results include the effects of more completely
developed medical costs payable estimates associated with previously reported periods.
