IP health plan premiums are established by the OHCA.  Employees and college students are responsible for up to 20 percent of their IP health plan premium.  The employees are also responsible for up to 20 percent of their spouse's IP health plan premium if the dependent is included in the program.  The combined portion of the employee's or college student's cost sharing for IP health plan premiums cannot exceed four percent of his/her gross annual household income computed monthly.
