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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DM10 includes procedures performed to deliver brachytherapy to the breast, left. These ICD-10-PCS codes are used for inpatient documentation when a patient undergoes internal radiation therapy to the left breast for treatment of cancer or other targeted lesions. Accurate coding within the ICD-10-PCS DM10 group is essential for proper inpatient reimbursement, as it captures the specific brachytherapy procedure performed and supports clinical documentation accuracy.

Breast, Left Brachytherapy Procedure Overview

This code group includes inpatient brachytherapy procedures that place radioactive sources directly in or near the left breast to treat malignant or premalignant lesions. Procedures target the breast body system and involve implantation, positioning, or removal of radioactive material or delivery devices. Accurate ICD-10-PCS coding ensures the inpatient record reflects the specific brachytherapy treatment delivered and supports correct case mix assignment and payment.

When to Use

Use a code from this group when internal radiation is intentionally delivered to the left breast using implanted sources or intracavitary/intraluminal applicators during an inpatient stay. Select the code that reflects the exact technique, approach, and any removal or repositioning performed as part of the brachytherapy treatment.

Typical Clinical Scenarios

A 58-year-old woman with a recently diagnosed, localized left-breast invasive ductal carcinoma elects breast-conserving therapy; after lumpectomy with clear margins, she is admitted for planned internal radiation therapy to deliver a concentrated dose to the lumpectomy cavity using temporarily implanted radioactive sources to minimize exposure to surrounding tissue. This inpatient procedure is performed to complete adjuvant therapy and reduce local recurrence risk. Typical codes: DM1098Z, DM1099Z
A 72-year-old woman with multiple comorbidities and a small left-breast tumor who is not a candidate for external beam radiation presents for definitive brachytherapy as a primary modality; during a scheduled inpatient admission, low-dose-rate seeds are implanted into the left breast to deliver continuous local radiation over time. The inpatient setting allows monitoring for immediate postimplant complications and ensures accurate placement of permanent seeds. Typical codes: DM10B9Z, DM10BBZ
A 65-year-old woman previously treated with left-breast brachytherapy presents with persistent wound drainage and suspected partial extrusion of implanted applicators; she is admitted for removal and possible repositioning of the radioactive delivery device and management of local infection. The procedure targets removal/repositioning of brachytherapy sources from the left breast to resolve the complication and protect surrounding tissue. Typical codes: DM109YZ, DM10BYZ
