The NHIC will accept CARE forms up to 90 days before the expiration of LOC or MN. Timely submission within this period is crucial to ensure healthcare coverage.
Step-by-step explanation:
The number of days the National Health Insurance Corporation (NHIC) will accept CARE forms before the expiration of Level of Care (LOC) or Medical Necessity (MN) is 90 days. It's important to be aware of the expiration dates and timely submission requirements to ensure continuous coverage and prevent issues with healthcare services.
