About the DB1 Code Range

Brachytherapy is a specialized form of radiation therapy involving the direct placement of radioactive material into or near tumors within the body. The ICD-10-PCS root operation DB1 – Brachytherapy applies to administering targeted radiation treatment specifically to the Respiratory System.

This root operation encompasses a range of procedures delivering either High Dose Rate (HDR) or Low Dose Rate (LDR) radiation directly to sites such as the Trachea, Bronchus, Lung, Pleura, Mediastinum, Chest Wall, and Diaphragm. The coding system specifies the type of radioactive isotope used, including Cesium 131, Cesium 137, Iridium 192, Iodine 125, Palladium 103, Californium 252, and others. For example, code DB1097Z represents HDR brachytherapy of the trachea using Cesium 137, whereas DB12B9Z denotes LDR brachytherapy of the lung using Iodine 125.
These ICD-10-PCS brachytherapy codes allow for precise documentation of treatment approach, target body part, and radioactive source, critical for treatment planning, billing, and clinical reporting within respiratory radiation therapy.

Questions About This Page

How many billable codes are in the DB1 range?

Of the 99 codes in this range, 98 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 DB1 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 respiratory system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
