When the local emergency medical system is destroyed, compromised or overwhelmed, FEMA funds extraordinary costs of operating emergency rooms and temporary medical facilities for survivors, for up to 30 days from the declaration unless FEMA approves more time.
Patient-by-patient records showing insurance and other coverage was checked, plus facility, staffing and supply costs. Extensions need a justification and an analysis of options with costs.
Build insurance screening into intake from the first patient. Reconstructing coverage checks later is nearly impossible.
