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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CW54 includes procedures performed to introduce radioactive materials into the chest and abdomen. These ICD-10-PCS codes are used for inpatient documentation when nonimaging nuclear medicine probe techniques are performed to study distribution, fate, or absorption of radioactive substances in the chest and abdomen. Accurate coding within the ICD-10-PCS CW54 group is essential for proper inpatient reimbursement, as it captures the specific nuclear medicine procedure performed and supports clinical documentation accuracy.

Chest And Abdomen Nonimaging Nuclear Medicine Probe Procedure Overview

This code group covers procedures that introduce radioactive materials into the chest and abdomen for nonimaging nuclear medicine probe assessment of distribution or fate of substances and for measurement of absorption from an external source. These procedures target anatomical regions of the chest and abdomen and use nuclear medicine techniques rather than traditional imaging modalities. Accurate ICD-10-PCS coding ensures the inpatient record reflects the specific diagnostic nuclear medicine probe procedure performed and supports appropriate case mix assignment and reimbursement.

Select the specific code that corresponds to the anatomical region and the nonimaging nuclear medicine probe operation documented in the medical record.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
CW541ZZ	Nonimaging Nuclear Medicine Probe of Chest and Abdomen using Technetium 99m (Tc-99m)
CW54DZZ	Nonimaging Nuclear Medicine Probe of Chest and Abdomen using Indium 111 (In-111)
CW54YZZ	Nonimaging Nuclear Medicine Probe of Chest and Abdomen using Other Radionuclide

Typical Clinical Scenarios

An elderly patient is admitted with unexplained pleural effusion and intermittent hemoptysis. Clinicians perform a nonimaging nuclear medicine probe study of the chest and abdomen using Technetium 99m to evaluate pleural fluid dynamics and localize areas of increased radiotracer accumulation to help differentiate causes of the effusion. The test is requested during the inpatient stay to guide further diagnostic and therapeutic decisions. Typical codes: CW541ZZ
A middle-aged patient with a history of neuroendocrine tumor is admitted for planned inpatient evaluation of suspected occult abdominal metastases causing intermittent abdominal pain. A nonimaging nuclear medicine probe procedure of the chest and abdomen using Indium 111 is performed to assess distribution of a radiolabeled tracer that targets tumor cells and to help stage disease as part of the inpatient workup. The procedure is scheduled and documented preoperatively during the admission. Typical codes: CW54DZZ
A recently hospitalized patient develops unexplained persistent abdominal pain after prior diagnostic studies were inconclusive; clinicians perform a repeat nonimaging nuclear medicine probe study of the chest and abdomen using an alternative radionuclide to evaluate delayed tracer uptake and clarify prior ambiguous findings. This repeat inpatient procedure is done to reassess tracer distribution and inform changes in management when earlier imaging did not resolve the diagnosis. Typical codes: CW54YZZ
