ICD-10-PCS Code For Lower Extremity Veins, Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C51C includes procedures performed to image venous structures in the left lower extremity using planar nuclear medicine techniques. These ICD-10-PCS codes are used for inpatient documentation when radiopharmaceuticals are introduced for single-plane imaging of radioactive emissions from the left lower extremity veins. Accurate coding within the ICD-10-PCS C51C group is essential for proper inpatient reimbursement, as it captures the specific diagnostic imaging procedure performed and supports clinical documentation accuracy.

Lower Extremity Veins, Left Planar Nuclear Medicine Imaging Procedure Overview

This code group covers planar nuclear medicine imaging procedures that introduce radioactive materials to capture single-plane images of the left lower extremity venous system. These procedures target the veins and involve administration of radiopharmaceuticals and imaging of emitted radiation to evaluate venous anatomy or function. Accurate coding ensures the inpatient record reflects the specific nuclear medicine procedure performed and supports appropriate inpatient reimbursement based on the recorded diagnostic imaging service.

When to Use

Use a code from this group when a radiopharmaceutical is administered to perform planar nuclear medicine imaging specifically targeting the left lower extremity venous system. These codes apply when single-plane imaging is obtained to evaluate venous anatomy or function during an inpatient stay.

C51CYZZ	Planar Nuclear Medicine Imaging of Left Lower Extremity Veins using Other Radionuclide

Typical Clinical Scenarios

An elderly hospitalized patient presents with new-onset unilateral left leg swelling and pain after recent hip surgery; there is clinical concern for acute deep venous thrombosis and bedside ultrasound is inconclusive due to extensive dressings and edema, so inpatient planar nuclear medicine venous imaging is ordered to evaluate left lower extremity venous outflow. The study introduces a radiopharmaceutical and acquires single-plane images of the left lower extremity veins to assess for perfusion defects or flow interruption. Typical codes: C51C1ZZ, C51CYZZ
A middle-aged patient admitted electively for evaluation of chronic venous insufficiency with recurrent left leg ulceration and suspected venous reflux not fully characterized by duplex ultrasound, scheduled for inpatient diagnostic imaging to map venous anatomy prior to possible intervention. Planar nuclear medicine imaging of the left lower extremity veins is performed after radiotracer administration to visualize venous drainage patterns and guide treatment planning. Typical codes: C51CYZZ, C51C1ZZ
A postoperative inpatient develops increasing left calf swelling and pain several days after vascular surgery on the contralateral limb, and duplex imaging is nondiagnostic; the team orders a targeted planar radionuclide venogram of the left lower extremity to rule out subacute thrombus extension as a complication. The procedure involves introducing a radiopharmaceutical and capturing single-plane images of the left lower extremity veins to detect thrombotic filling defects. Typical codes: C51C1ZZ
