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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CP1C includes procedures performed to capture single-plane nuclear medicine images of the musculoskeletal structures in the lower extremity, right. These ICD-10-PCS codes are used for inpatient documentation when planar nuclear medicine imaging is performed using introduced radioactive materials to visualize the right lower extremity. Accurate coding within the ICD-10-PCS CP1C group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Lower Extremity, Right Planar Nuclear Medicine Imaging Procedure Overview

This procedure group includes planar nuclear medicine imaging of the right lower extremity and targets the musculoskeletal system. Procedures introduce radioactive materials into the body to produce single-plane images from captured radioactive emissions. Accurate coding of these planar nuclear medicine procedures ensures inpatient records reflect the imaging performed and supports appropriate reimbursement determinations.

When to Use

Use a code from this group when planar nuclear medicine imaging of the right lower extremity is performed with introduction of radioactive materials for single-plane image capture. These codes apply when the clinical objective is to image musculoskeletal structures of the right lower extremity using nuclear medicine techniques.

CP1C1ZZ	Planar Nuclear Medicine Imaging of Right Lower Extremity using Technetium 99m (Tc-99m)
CP1CYZZ	Planar Nuclear Medicine Imaging of Right Lower Extremity using Other Radionuclide

Typical Clinical Scenarios

An elderly patient with acute, unexplained pain and swelling localized to the right lower extremity is admitted from the emergency department after a non-diagnostic X-ray; clinicians suspect occult bone pathology such as a stress fracture or osteomyelitis and require functional imaging to localize abnormal radiotracer uptake in bone. A planar nuclear medicine study is performed after intravenous administration of a bone-seeking radionuclide to obtain single‑plane images of the affected musculoskeletal region. Typical codes: CP1C1ZZ, CP1CYZZ
A middle-aged outpatient is admitted for planned inpatient evaluation of chronic, progressive right knee and lower leg pain with prior inconclusive MRI; the goal is to assess for focal increased bone turnover or prosthetic loosening using targeted nuclear imaging of the right lower extremity. Inpatient planar imaging with an injected radiotracer is used to visualize areas of increased osteoblastic activity and guide further management. Typical codes: CP1C1ZZ, CP1CYZZ
A patient with diabetes presents with a deep, nonhealing ulcer on the right foot and signs concerning for underlying osteomyelitis; after initial clinical assessment and lab markers, the team orders a nuclear medicine bone scan focused on the right lower extremity to detect focal infection versus soft tissue involvement. Planar imaging following radionuclide introduction is obtained to evaluate for increased uptake consistent with osteomyelitis. Typical codes: CP1C1ZZ, CP1CYZZ
