ICD-10-PCS Code For Chest: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CW13 includes procedures performed to capture planar nuclear medicine images of functional processes in the chest. These ICD-10-PCS codes are used for inpatient documentation when a planar nuclear medicine study of the chest is performed using introduced radioactive material to produce two-dimensional images. Accurate coding within the ICD-10-PCS CW13 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Chest Planar Nuclear Medicine Imaging Procedure Overview

This group includes planar nuclear medicine imaging procedures that capture two-dimensional images of the chest by introducing radioactive materials and detecting emitted radiation. These procedures target the anatomical regions of the chest within the nuclear medicine section and are used to evaluate functional and physiologic processes rather than just anatomy. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the specific imaging modality and supports appropriate case classification and payment.

When to Use

Use a code from this group when a planar nuclear medicine study of the chest is performed involving administration of radioactive material and capture of emitted radiation for image generation. These codes apply to inpatient encounters where the imaging modality and anatomical focus on the chest must be documented for clinical and billing purposes.

Typical Clinical Scenarios

A 68-year-old male is admitted with acute onset shortness of breath and hypoxemia after recent hip replacement. Clinical concern for pulmonary embolism prompts inpatient nuclear medicine evaluation to assess pulmonary perfusion using technetium-based radiotracer for planar ventilation-perfusion correlation. A planar chest nuclear medicine study is performed to detect perfusion defects consistent with emboli. Typical codes: CW131ZZ
A 54-year-old female with a history of metastatic thyroid carcinoma is admitted for planned inpatient staging and assessment of chest metastatic involvement. The team orders a planar nuclear medicine scan using Iodine-123 to evaluate functional uptake in thoracic lesions and to help guide further management during the hospitalization. The study captures two-dimensional images of radioactive emissions from the chest after tracer administration. Typical codes: CW13FZZ
A 72-year-old male previously treated for lung infection develops persistent focal metabolic activity on follow-up imaging and is admitted for further evaluation of unresolved chest pathology. To differentiate active infection or inflammatory uptake from scar, a planar nuclear medicine chest imaging study using Gallium-67 is performed during the inpatient stay to localize ongoing radiotracer accumulation in the chest. Typical codes: CW13LZZ
