Right Lower Extremity Arteries ICD-10-PCS Coding

ICD-10-PCS Code For Right Lower Extremity Arteries: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group B44F includes procedures performed to image arterial anatomy and blood flow in the right lower extremity. These ICD-10-PCS codes are used for inpatient documentation when diagnostic ultrasonography of the right lower extremity arteries is performed to evaluate arterial patency, stenosis, occlusion, or flow abnormalities. Accurate coding within the ICD-10-PCS B44F group is essential for proper inpatient reimbursement, as it captures the diagnostic procedure performed and supports clinical documentation accuracy.

Lower Extremity Arteries Ultrasonography Procedure Overview

This code group covers ultrasonography of the right lower extremity arteries, imaging arterial anatomy and flow using high-frequency sound waves. Procedures in this group target the lower arteries of the right leg to visualize vessel structure and blood flow for diagnosis and monitoring. Accurate ICD-10-PCS coding ensures inpatient records reflect the diagnostic imaging performed and supports appropriate reimbursement and case mix assignment.

When to Use

Use a code from this group when inpatient diagnostic ultrasonography is performed specifically on the right lower extremity arterial system to evaluate suspected peripheral arterial disease, thrombosis, or other vascular abnormalities. Select the appropriate code when the procedure documents imaging of arterial anatomy or flow information developed from reflected and attenuated high-frequency sound waves.

Ultrasonography of Right Lower Extremity Arteries

Typical Clinical Scenarios

An elderly patient with known peripheral arterial disease is admitted for worsening rest pain and a nonhealing ischemic ulcer on the right foot; inpatient evaluation includes noninvasive vascular imaging to assess arterial patency, locate high-grade stenosis, and map flow prior to possible revascularization. A diagnostic right lower extremity arterial ultrasound with Doppler is performed to visualize vessel anatomy and flow dynamics. Typical codes: B44FZZZ
A middle-aged patient presents to the emergency department with sudden onset severe right leg pain, pallor, and diminished distal pulses suspicious for acute arterial occlusion; they are admitted for urgent workup to confirm occlusion and guide immediate management. Bedside or inpatient ultrasonography of the right lower extremity arteries is used to detect thrombus and assess flow compromise. Typical codes: B44FZZZ
A hospitalized patient with a recent endovascular right lower extremity arterial procedure develops concern for recurrent stenosis versus residual flow abnormality; inpatient follow-up imaging is ordered to evaluate intraluminal flow and determine need for repeat intervention. A focused intravascular or detailed ultrasonographic assessment of the right lower extremity arteries is performed to characterize flow and anatomy. Typical codes: B44FZZ3, B44FZZZ
