ICD-10-PCS Code For Upper Extremity Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CP19 includes procedures performed to capture single-plane diagnostic images after introduction of radioactive materials in the upper extremity, left. These ICD-10-PCS codes are used for inpatient documentation when a planar nuclear medicine study of the left upper extremity is performed to evaluate musculoskeletal conditions using radiopharmaceuticals. Accurate coding within the ICD-10-PCS CP19 group is essential for proper inpatient reimbursement, as it captures the specific imaging procedure performed and supports clinical documentation accuracy and appropriate case mix and payment.

Upper Extremity, Left Planar Nuclear Medicine Imaging Procedure Overview

This procedure group includes planar nuclear medicine imaging studies of the left upper extremity that capture radioactive emissions to create single-plane diagnostic images. These procedures target the musculoskeletal system and involve introduction of a radiopharmaceutical followed by image capture of emitted radiation. Accurate ICD-10-PCS coding ensures inpatient records reflect the imaging performed and supports appropriate facility reimbursement and case mix assignment.

ICD-10-PCS Code	Description
CP191ZZ	Planar Nuclear Medicine Imaging of Left Upper Extremity using Technetium 99m (Tc-99m)
CP19YZZ	Planar Nuclear Medicine Imaging of Left Upper Extremity using Other Radionuclide

Typical Clinical Scenarios

An elderly patient with a history of metastatic breast cancer is admitted for progressive severe left forearm bone pain and suspected osseous metastasis; inpatient workup includes localization of radiotracer uptake to assess extent of bony involvement in the left upper extremity when cross-sectional imaging is inconclusive, prompting a planar nuclear medicine study after radiopharmaceutical administration. Typical codes: CP191ZZ, CP19YZZ
A middle-aged patient presents to the hospital with acute left wrist pain and swelling after a fall with concern for occult fracture or stress injury; because plain radiographs are nondiagnostic and the patient cannot be discharged for outpatient imaging, an inpatient planar bone scan of the left upper extremity is performed following injection of a radionuclide to evaluate for focal increased uptake. Typical codes: CP191ZZ
A young adult with chronic regional pain syndrome of the left hand/forearm hospitalized for severe refractory pain undergoes inpatient functional assessment to guide management; a planar nuclear medicine study of the left upper extremity is obtained after radiotracer introduction to identify altered perfusion or bone turnover patterns associated with the condition. Typical codes: CP19YZZ
