Thank you for your inquiry on CMS190v13, Intensive Care Unit Venous Thromboembolism Prophylaxis. Boarding inpatients in the ICU due to bed availability will put those patients in the VTE-2 measure's denominator. For the circumstance you described, the patient was admitted to the hospital for Med Surg services, but temporally assigned a bed in the ICU for because it's the only open bed in the facility the only open bed in the facility. If ICU LOS < 1 day, the patient would be excluded from the denominator of the performance rate if patient did not receive any VTE prophylaxis.
