In the Catastrophic Illness in Children Relief Fund Program, any illness can be "catastrophic" based on uncovered eligible medical expenses and the family's income in a prior 12-month time period.

A catastrophic illness is any illness or condition, acute or chronic, for which expenses are incurred that are not fully covered by insurance, state, federal programs, or other sources and exceed the program's eligibility threshold.

There are no specific exclusions by diagnosis.
