OASIS Guidance: M1600 UTI in the Past 14 Days?

Posted by Melissa Cott on Jul 26, 2023

Medicare requires HHAs to monitor for healthcare-associated infections (HAI) as part of its overall Quality Assurance Performance Improvement (QAPI) initiative. Medicare’s Condition of Participation (§484.70 Condition of participation: Infection prevention and control) requires HHAs to “… maintain a coordinated agency-wide program for the surveillance, identification, prevention, control, and investigation of infectious and communicable diseases that is an integral part of the HHA’s quality assessment and performance improvement (QAPI) program."

'(M1600) Urinary Tract Infection in the past 14 days?' is included in the OASIS assessment as part of your infection surveillance activities.

This question contributes to your infection surveillance program to determine: UTI Still Lingers After Antibiotics? What Patients Need to Know...

  1. patients not receiving appropriate antibiotics,
  2. patients who could have been receiving less expensive antibiotics, and 
  3. patients receiving prolonged antibiotic therapy. 

These activities help to reduce antibiotic-resistant pathogen: methicillin-resistant Staphylococcus aureus (MRSA), Clostridium difficile-associated diarrhea (CDAD), and vancomycin-resistant Enterococcus (VRE).


  • Start of care
  • Resumption of care
  • Discharge from agency – not to an inpatient facility



  • The term “past 14 days” is the two-week period immediately preceding the Start/Resumption of Care date (or for Discharge, the M0090 Date Assessment Completed). This means that for purposes of counting the 14-day period, the Start of Care date is day 0 and the day immediately prior to the Start of Care date is day 1. For example, if the patient’s SOC date is August 20, any treatment for a UTI occurring on or after August 6 would be considered.
  • Unknown is not an option at Discharge from Agency.
  • Enter Response 0 – No, if patient has not been treated for a UTI within the past two weeks, including if the patient had symptoms of a UTI or a positive culture for which the physician did not prescribe treatment, or the treatment ended more than 14 days ago.
  • Enter Response 1 – Yes, when the patient has been prescribed an antibiotic within the past 14 days specifically for a confirmed or suspected UTI.
  • Enter Response 1 – Yes, if the patient is on prophylactic treatment and develops a UTI.
  • Enter “NA” – if the patient is on prophylactic treatment to prevent UTIs.
