ICD-10-PCS Code for Pelvic Region: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CW5J includes procedures performed to detect or measure radioactive emissions in the pelvic region. These ICD-10-PCS codes are used for inpatient documentation when nonimaging nuclear medicine probe techniques are employed to study the distribution or fate of radioactive materials in pelvic tissues. Accurate coding within the ICD-10-PCS CW5J group is essential for proper inpatient reimbursement, as it captures the specific diagnostic procedure performed and supports clinical documentation accuracy.

Pelvic Region Nonimaging Nuclear Medicine Probe Procedure Overview

This group includes procedures that introduce radioactive materials or measure radioactive emissions using a probe in the pelvic region and target anatomical regions. These nonimaging nuclear medicine probe procedures detect distribution or absorption of radioactive substances within pelvic tissues. Accurate ICD-10-PCS coding for these procedures ensures inpatient records reflect the diagnostic technique used and supports appropriate case mix and payment.

J	Body Part	Pelvic Region

When to Use

Use a code from this group when a nonimaging nuclear medicine probe is used intraoperatively or diagnostically in the pelvic region to detect radioactive emissions or to evaluate the fate of introduced radiotracers. These codes apply when the procedure involves direct probe-based measurement rather than imaging modalities.

ICD-10-PCS Code	Description
CW5J1ZZ	Nonimaging Nuclear Medicine Probe of Pelvic Region using Technetium 99m (Tc-99m)
CW5JDZZ	Nonimaging Nuclear Medicine Probe of Pelvic Region using Indium 111 (In-111)
CW5JYZZ	Nonimaging Nuclear Medicine Probe of Pelvic Region using Other Radionuclide

Typical Clinical Scenarios

A postpartum patient with persistent heavy vaginal bleeding after delivery is admitted for evaluation when ultrasound and exam are inconclusive for the source of hemorrhage; a surgeon introduces a nonimaging nuclear medicine probe into the pelvic cavity after administration of a radiotracer to localize active bleeding from pelvic vessels or the uterine wall for potential targeted intervention. Typical codes: CW5J1ZZ, CW5JYZZ
An inpatient with a known pelvic malignancy (for example, recurrent cervical or endometrial cancer) is scheduled for assessment of sentinel lymph node mapping during a planned surgical staging procedure; a radiolabeled tracer is injected and a nonimaging nuclear medicine probe is used intraoperatively in the pelvic region to detect tracer uptake and guide selective lymphadenectomy. Typical codes: CW5JDZZ, CW5J1ZZ
A trauma patient with pelvic fractures and unexplained continued pelvic hemorrhage is taken to the OR emergently; after systemic administration of a radiotracer, a nonimaging nuclear medicine probe is used in the pelvic region to detect focal radiotracer accumulation indicating active bleeding sites that require hemostatic control. Typical codes: CW5J1ZZ, CW5JYZZ
