Health PLan Premium. If a health plan covers 150,000 lives expects 25 myocardial infarctions to occur each year within the covered lives, expects a length of stay of 4.5 days for each MI, and has to pay an average of $950 per day each day the MI patient is in the hospital, what is the PMPM cost to the health plan? What would have to be charged to the patient or employer if the health plan has administrative cost equaling 10 percent of its cost and it wants a profit margin of 7 percent? What if the hospital refuses to take the new rate, an employer refuses to pay the new premium, and that employer decides to take its employees (10,000) to another health plan? Also suppose these departing employees/health plan members represent 6 percent of the total MI cases. What would the new PMPM premium be for the 140,000 remaining members?
