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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C51D includes procedures performed to image the lower extremity veins using planar nuclear medicine techniques after introduction of radioactive materials. These ICD-10-PCS codes are used for inpatient documentation when a single‑plane nuclear medicine study of the bilateral lower extremity venous system is performed. Accurate coding within the ICD-10-PCS C51D group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Lower Extremity Veins Planar Nuclear Medicine Imaging Procedure Overview

This procedure group includes planar nuclear medicine imaging studies of the bilateral lower extremity venous system that capture radioactive emissions to create single‑plane images. These studies target the veins and involve introduction of radioactive materials followed by image capture using planar nuclear medicine techniques. Accurate ICD-10-PCS coding for these procedures ensures inpatient documentation reflects the specific imaging performed and supports correct case mix assignment and payment.

When to Use

Use a code from this group when an inpatient receives a planar nuclear medicine study of the bilateral lower extremity veins with administration of radioactive material and capture of single‑plane images. These codes apply when the clinical intent is to image venous structure or function in both lower extremities using planar nuclear medicine techniques.

Typical Clinical Scenarios

An elderly hospitalized patient presents with sudden unilateral leg swelling and pain after recent hip fracture surgery, raising concern for deep venous thrombosis that may involve both lower extremities due to immobilization; the inpatient team orders a planar nuclear medicine venous imaging study of the bilateral lower extremity veins to evaluate venous perfusion and detect thrombotic occlusion when duplex ultrasound is inconclusive. Typical codes: C51D1ZZ, C51DYZZ
A middle-aged patient admitted for investigation of chronic, bilateral lower extremity swelling and venous insufficiency symptoms undergoes a planned inpatient workup to assess venous reflux and bilateral venous anatomy; a single‑plane planar nuclear medicine study of the bilateral lower extremity veins is performed following injection of radiotracer to map venous flow and guide further management. Typical codes: C51D1ZZ, C51DYZZ
A hospitalized trauma patient with multiple fractures develops concern for bilateral lower extremity venous thromboembolism during their ICU stay and requires imaging when bedside ultrasound is limited by casts and dressings; a planar nuclear medicine imaging study of the bilateral lower extremity veins using a radiopharmaceutical is performed to evaluate for thrombus in both legs.
