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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CP16 includes procedures performed to perform planar nuclear medicine imaging in the pelvis. These ICD-10-PCS codes are used for inpatient documentation when a radiopharmaceutical is introduced and single-plane images are obtained to assess pelvic musculoskeletal function or pathology. Accurate coding within the ICD-10-PCS CP16 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy.

Pelvis Planar Nuclear Medicine Imaging Procedure Overview

This code group covers planar nuclear medicine imaging procedures of the pelvis, which involve introduction of radioactive materials and capture of emitted radiation to produce single-plane diagnostic images. These procedures target the musculoskeletal structures of the pelvis and are performed to evaluate function or pathology using radiopharmaceuticals. Accurate ICD-10-PCS coding is important for inpatient reimbursement because it documents the specific imaging technique and anatomic focus used in patient care.

When to Use

Use codes from this group when a radiopharmaceutical is administered and planar nuclear medicine images of the pelvic musculoskeletal structures are acquired during an inpatient encounter. These codes apply when single-plane emission capture is performed to evaluate pelvic bone or soft-tissue function or suspected pathology.

CP161ZZ	Planar Nuclear Medicine Imaging of Pelvis using Technetium 99m (Tc-99m)
CP16YZZ	Planar Nuclear Medicine Imaging of Pelvis using Other Radionuclide

Typical Clinical Scenarios

An elderly patient with known metastatic prostate cancer is admitted for worsening localized pelvic pain and elevated alkaline phosphatase; clinicians suspect new pelvic bone metastases versus degenerative change and order inpatient planar nuclear medicine imaging after radiopharmaceutical administration to evaluate pelvic osseous involvement. This single‑plane study targets the musculoskeletal pelvis to localize increased radiotracer uptake associated with metastatic disease. Typical codes: CP161ZZ, CP16YZZ
A middle‑aged patient presents post‑motor vehicle collision with focal pelvic tenderness and equivocal x‑rays; because the patient is admitted for observation and initial imaging is inconclusive for pelvic bone injury, a planar nuclear medicine bone scan of the pelvis is performed after injection of a radiopharmaceutical to assess for occult fracture or bone contusion. The procedure captures single‑plane emissions focused on pelvic bones to detect focal uptake consistent with acute skeletal injury. Typical codes: CP161ZZ, CP16YZZ
A patient with chronic pelvic osteomyelitis and persistent pain despite antibiotics is admitted for assessment of ongoing bone activity; inpatient planar nuclear medicine imaging is obtained using a radiotracer to evaluate active infection or inflammatory changes in the pelvic bones and guide further management. Single‑plane pelvic musculoskeletal imaging helps differentiate active osteomyelitis from chronic changes. Typical codes: CP161ZZ, CP16YZZ
