  • If no mRS is documented, select “UTD”.
  • Documentation of a mRS obtained within the 90 day timeframe (i.e., 75 to 105 days after hospital discharge) via telephone or in-person is acceptable.
  • If the patient cannot be interviewed because of communication deficits or other limitations, an interview with the patient's caregiver is acceptable.

  • If the patient and/or caregiver refuse to be interviewed, select allowable value “7”.
  • If documentation reflects that the mRS could not be obtained because the patient is a resident of a nursing home or extended/immediate care facility, and the facility refuses to provide patient information due to HIPPA regulations or other reasons, select allowable value "7".
