An illness, injury, impairment, physical or mental condition that involves either:

• Inpatient care (i.e. an overnight stay) in a hospital, hospice or residential medical care facility, including any period of incapacity (i.e. inability to work, attend school, or perform other regular daily activities) or subsequent treatment in connection with such inpatient care; or
• Continuing treatment by a health care provider, which includes:
  • A period of incapacity lasting more than three consecutive, full calendar days, and any subsequent treatment or period of incapacity relating to the same condition, that also includes:
    • treatment two or more times by or under the supervision of a health care provider(i.e., in-person visits, the first within 7 days and both within 30 days of the first day of incapacity); or
    • one treatment by a health care provider (i.e., an in-person visit with 7 days of the first day of incapacity) with a continuing regimen of treatment (e.g., prescription medication, physical therapy).
  • Any period of incapacity due to pregnancy, for prenatal care, or for her own serious health condition following the birth of a child. The expectant mother is entitled to leave for incapacity due to pregnancy even though she does not receive treatment from a health care provider during the absence, and even if the absence does not last for more than three consecutive calendar days; or
  • Any period of incapacity or treatment for a chronic serious health condition which continues over an extended period of time, requires periodic visits (at least twice a year) to a health care provider, and may involve occasional episodes of incapacity (e.g. asthma, diabetes, epilepsy, etc.). A visit to the health care provider is not necessary for each absence; or
  • A period of incapacity that is permanent or long-term due to a condition for which treatment may not be effective (e.g., Alzheimer's, a severe stroke, terminal stages of a disease, etc.). Only supervision of a health care provider is required, rather than active treatment.
  • Any absences to receive multiple treatments for restorative surgery or for a condition that would likely result in a period of incapacity of more than three days if not treated, such as cancer (chemotherapy, radiation), severe arthritis (physical therapy), or kidney disease (dialysis).
