About the D71 Code Range

The ICD-10-PCS root operation Brachytherapy (code D71) refers to a form of radiation therapy where radioactive sources are placed directly into or near target tissues. This operation is specifically classified under Radiation Therapy.

Brachytherapy in the lymphatic and hematologic system involves delivering high or low dose radiation to precise body parts like the bone marrow, thymus, spleen, and various lymphatic regions including neck, axillary, thorax, abdomen, pelvis, and inguinal lymphatics. The ICD-10-PCS codes distinguish between High Dose Rate (HDR) and Low Dose Rate (LDR) brachytherapy, as well as the radioactive isotopes used such as Cesium 131, Cesium 137, Iridium 192, Iodine 125, Palladium 103, and Californium 252. For example, code D71097Z denotes HDR brachytherapy of bone marrow using Cesium 137, while D717B9Z represents LDR brachytherapy of pelvis lymphatics using Iodine 125. This specificity helps accurately document treatment details in oncology and hematology care.

Questions About This Page

How many billable codes are in the D71 range?

Of the 127 codes in this range, 126 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.

What does the D71 range classify?

The range classifies Brachytherapy procedures, a type of radiation therapy in which radioactive material sealed in needles, seeds, wires, or catheters is placed directly into or near a tumor, performed on the lymphatic and hematologic system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
