About the D01 Code Range

The ICD-10-PCS root operation Brachytherapy (code D01) involves the targeted delivery of radioactive material directly to the Central and Peripheral Nervous System to treat disease. This form of radiation therapy is classified within the Radiation Therapy section and focuses on precise, localized treatment.

The brachytherapy codes illustrate various applications including treatment of the Brain, Brain Stem, Spinal Cord, and Peripheral Nerve using different radioactive isotopes. For example, High Dose Rate (HDR) Brachytherapy of the brain can use isotopes like Cesium 137 (Cs-137) (code D01097Z) or Iridium 192 (Ir-192) (code D01098Z). Similarly, Low Dose Rate (LDR) Brachytherapy options include use of Palladium 103 (Pd-103) (code D010BBZ) with a unidirectional source as in code D010BB1. Each code specifies the dose rate, target nervous system part, and isotope, allowing detailed documentation of this precise radiation treatment method.

Questions About This Page

How many billable codes are in the D01 range?

Of the 57 codes in this range, 56 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 D01 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 central and peripheral nervous system. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
