ICD-10-PCS Code For Left Breast: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CH11 includes procedures performed to introduce radioactive materials for planar nuclear medicine imaging in the left breast. These ICD-10-PCS codes are used for inpatient documentation when single-plane nuclear imaging of the left breast is performed to evaluate physiological function or localize lesions. Accurate coding within the ICD-10-PCS CH11 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Left Breast Planar Nuclear Medicine Imaging Procedure Overview

This procedure group comprises planar nuclear medicine imaging of the left breast, which involves introducing radioactive materials and capturing single-plane images from emitted radiation. These procedures target the skin, subcutaneous tissue, and breast and are performed to visualize physiological function and detect abnormalities. Accurate ICD-10-PCS coding is important for reflecting the imaging performed and for appropriate inpatient documentation and reimbursement.

When to Use

Use a code from this group when a radioactive tracer is administered specifically for planar nuclear medicine imaging of the left breast during an inpatient stay. These codes apply when single-plane image acquisition of the left breast is performed to evaluate or localize pathology.

ICD-10-PCS Code	Description
CH111ZZ	Planar Nuclear Medicine Imaging of Left Breast using Technetium 99m (Tc-99m)
CH11SZZ	Planar Nuclear Medicine Imaging of Left Breast using Thallium 201 (Tl-201)
CH11YZZ	Planar Nuclear Medicine Imaging of Left Breast using Other Radionuclide

Typical Clinical Scenarios

An inpatient postoperative patient with a palpable mass and persistent seroma in the left breast after lumpectomy is evaluated to differentiate residual tumor from postoperative changes. A technetium-99m labeled radiotracer is injected and single-plane breast nuclear images are acquired to help localize metabolically active tissue in the surgical bed. The imaging guides further clinical management during the same hospital stay. Typical codes: CH111ZZ
An elderly patient admitted from the emergency department with focal left breast pain and a suspicious area on ultrasound undergoes inpatient diagnostic localization to assess for occult malignancy. Thallium-201 planar nuclear imaging of the left breast is performed to evaluate tracer uptake characteristics of the lesion when immediate inpatient diagnostic clarification is required. Results assist the care team in deciding urgent biopsy versus observation. Typical codes: CH11SZZ
A patient with a history of multifocal left breast cancer undergoing inpatient assessment for recurrent disease has indeterminate findings on mammography; an alternative radionuclide is chosen due to prior tracer allergy and prior imaging limitations. Single-plane planar nuclear imaging using an alternative radionuclide is performed on the left breast to localize recurrent lesions and inform the inpatient treatment plan. Typical codes: CH11YZZ
