Thank you for your question that applies to CMS104, CMS71, and CMS72 - Discharged on Antithrombotic Therapy (STK-2), Anticoagulation Therapy for Atrial Fibrillation/Flutter (STK-3), and Antithrombotic Therapy by End of Hospital Day 2 (STK-5), respectively. Patients with a Principal Diagnosis Code for hemorrhagic stroke are excluded from the STK eCQMs. Patients assigned a Principal Diagnosis Code for ischemic stroke are included in the measure population. A secondary diagnosis of hemorrhagic stroke assigned for hemorrhagic conversion/ hemorrhagic transformation usually represents a complication related to thrombolysis for ischemic stroke. Each measure has a denominator exception for a documented reason for not administering / prescribing antithrombotic therapy. The CMS72 (STK-5) denominator exception states, “Inpatient hospitalization for patients with a documented reason for not administering antithrombotic therapy the day of or day after hospital arrival”. The CMS104 (STK—2) denominator exception states, "Inpatient hospitalizations for patients with a documented reason for not prescribing antithrombotic therapy at discharge". The CMS71 (STK-3) denominator exception states, “Patients with a documented reason for not prescribing anticoagulation therapy at discharge”.
