Forget all that talk about Orange County being a saturated market for managed care.
Most county residents older than 65 haven't signed up for an HMO yet.
About 65% of the population of 265,000 local seniors get their benefits directly through the federal government's Medicare program, rather than a Medicare HMO, according to government figures..
No wonder Inter Valley Health Plan, a pint-sized, nonprofit HMO in Pomona, wants to expand its plan for seniors in the county.
Inter Valley's total senior membership of 15,000 in Southern California is dwarfed by those of the two Orange County-based for-profit giants, PacifiCare Health Systems Inc. and FHP International Corp. The Pomona company presently has only about 1,000 senior members in northern Orange County.
