About the B44 Code Range
The ICD-10-PCS root operation Ultrasonography (B44) refers to the use of ultrasound imaging to visualize arteries. This diagnostic procedure employs sound waves to create real-time images of vascular structures without using radiation.
Within the Imaging classification, the Ultrasonography codes cover various arteries including the Abdominal Aorta (B440ZZZ), Superior Mesenteric Artery (B444ZZZ), and Renal Arteries either right, left, or bilateral (B446ZZZ, B447ZZZ, B448ZZZ). These exams can be performed via the standard external approach or an Intravascular approach indicated by the suffix "3" in codes like B440ZZ3. The procedure is also utilized for arteries in the lower extremities, femoral artery, and even penile arteries. Applying these specific codes precisely documents the artery imaged and the technique used, which is crucial for accurate procedural records and billing in vascular imaging.
