Thank you for your inquiry about CMS165v11 Controlling High Blood Pressure. In this measure, blood pressure readings performed by the clinical staff, such as a medical assistant, nurse, or nurse practitioner, are qualifying documentation for evaluating numerator compliance. CMS defines clinicians as “those who provide: principal care for a patient where there is no planned endpoint of the relationship; expertise needed for the ongoing management of a chronic disease or condition; care during a defined period and circumstance, such as hospitalization; or care as ordered by another clinician. Clinicians may be physicians, nurses, pharmacists, or other allied health professionals.” We hope this helps.
