ICD-10-PCS Code For Upper Extremity Veins, Right: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C51N includes procedures performed to image the veins in the right upper extremity using planar nuclear medicine techniques. These ICD-10-PCS codes are used for inpatient documentation when radioactive materials are introduced to produce single-plane images of venous anatomy or function in the right upper extremity. Accurate coding within the ICD-10-PCS C51N group is essential for proper inpatient reimbursement, as it captures the specific imaging modality and anatomic target used for diagnosis and supports clinical documentation accuracy.

Upper Extremity Veins Planar Nuclear Medicine Imaging Procedure Overview

This procedure group includes planar nuclear medicine imaging studies that target the veins of the right upper extremity. Procedures involve introduction of radioactive materials and capture of emitted radiation to create single-plane images for diagnostic evaluation of the venous system. These studies are coded in the Nuclear Medicine section of the International Classification of Diseases, Tenth Revision, Procedure Coding System and accurate coding supports correct inpatient reimbursement. Precise coding ensures the inpatient record reflects the imaging modality and anatomic focus used for patient care.

C	Section	Nuclear Medicine
5	Body System	Veins
1	Operation	Planar Nuclear Medicine Imaging
N	Body Part	Upper Extremity Veins, Right

When to Use

Use a code from this group when radioactive tracers are administered and planar images are obtained specifically of the right upper extremity veins. These codes apply when the inpatient procedure involves nuclear medicine techniques rather than other imaging modalities.

ICD-10-PCS Code	Description
C51N1ZZ	Planar Nuclear Medicine Imaging of Right Upper Extremity Veins using Technetium 99m (Tc-99m)
C51NYZZ	Planar Nuclear Medicine Imaging of Right Upper Extremity Veins using Other Radionuclide

Typical Clinical Scenarios

A hospitalized postoperative patient on intravenous antibiotics develops acute swelling and erythema of the right forearm with concern for catheter-associated superficial thrombophlebitis or deep venous thrombosis; the inpatient team requests single‑plane nuclear medicine imaging after ultrasound is nondiagnostic to evaluate venous patency and thrombus extent in the right upper extremity. Typical codes: C51N1ZZ, C51NYZZ
An elderly inpatient with chronic renal insufficiency and a history of difficult peripheral access is evaluated pre–central venous catheter placement for hemodialysis because of suspected venous stenosis in the right arm; planar nuclear medicine venous imaging is performed to map right upper extremity venous anatomy and identify outflow obstruction before proceeding. Typical codes: C51N1ZZ, C51NYZZ
A patient admitted for management of cellulitis of the right hand has persistent arm swelling despite antibiotics and concern for occult venous leak after recent trauma; planar radionuclide imaging of the right upper extremity veins is obtained to assess venous integrity and flow dynamics as part of the inpatient workup. Typical codes: C51NYZZ, C51N1ZZ
