93970 CPT Code Definition: Clear Guide & Billing Tips

The numerical designator 93970 in the Current Procedural Terminology (CPT) system refers to a specific medical service: duplex scan of the extremity veins, complete bilateral study. This code encompasses the use of ultrasound technology to visualize and assess the deep and superficial venous systems of both legs or both arms. The examination includes real-time imaging with spectral and/or color Doppler analysis to evaluate venous patency, identify thrombi (blood clots), and assess venous valve competence.

Land Ordinance of 1785: A Key Definition + Impact

The formal enactment by the United States Congress on May 20, 1785, established a standardized system for surveying and selling the western lands acquired after the Revolutionary War. This legislative act provided a mechanism for orderly settlement and distribution of territory north and west of the Ohio River. It dictated that the land be surveyed into townships, each six miles square, further subdivided into thirty-six sections of one square mile (640 acres) each. Section 16 was specifically designated for the maintenance of public schools, illustrating the nascent nation’s commitment to education.

This structured approach facilitated westward expansion by minimizing land disputes and generating revenue for the young nation. The revenue generated from land sales helped to pay off national debt incurred during the Revolutionary War. The ordinance also established a framework for governance in these territories, laying the groundwork for future statehood. By emphasizing education and planned development, it shaped the social and political landscape of the American Midwest, fostering a culture of civic engagement and opportunity.

APUSH: Draft Riots Definition + Key Facts

The term designates a series of violent disturbances in the United States, most notably in New York City in July 1863, that arose in response to the federal government’s implementation of conscription laws during the Civil War. These events were characterized by widespread civil unrest, targeting both government institutions involved in the draft and, significantly, African Americans, who were often scapegoated for the war and perceived as economic competition. An example includes the destruction of property and physical assaults perpetrated by predominantly working-class white men against Black residents and businesses.

The significance of these events lies in their demonstration of deep social and economic tensions within the Union during the war. They highlight the resistance to the draft, particularly among those who could not afford to buy their way out of service, as well as the racial animosity that persisted even in the North. Its benefits lie in the understanding of the complexity of the Civil War and its impact on the entire nation, not just the battlefields. Its historical context underscores the role of class resentment and racial prejudice in shaping civilian experiences during wartime.

7+ Binocular Cues: Definition & Psychology Explained

Visual perception relies on a variety of depth cues that enable individuals to perceive the three-dimensional world. Among these are depth cues that require the use of both eyes. These depth cues, originating from the convergence and disparity of images processed by each eye, are essential for accurately judging distances and spatial relationships of nearby objects. A common example involves holding a finger close to the face and alternately closing each eye; the perceived position of the finger shifts significantly, illustrating the difference in the visual information received by each eye and the resultant impact on depth perception.

The utilization of two eyes for depth perception offers considerable advantages over monocular vision. It enhances accuracy in distance estimation, particularly for objects within arm’s reach, facilitating precise motor interactions with the environment. Historically, understanding these depth cues has been critical in various fields, including art, where artists employ principles of depth perception to create realistic depictions, and in the design of virtual reality systems, where accurately simulating depth is paramount for immersive experiences.
