About the DM0 Code Range

The ICD-10-PCS root operation Beam Radiation (DM0) refers to the targeted delivery of radiation beams to a specific body part for therapeutic purposes. This operation is classified under Radiation Therapy and focuses on treating conditions, such as cancer, by directing various types of radiation at the affected tissue.

Beam Radiation in this context is applied to the breast, using different radiation sources like photons at varying energy levels, electrons, heavy particles such as protons or ions, and neutrons. The codes differentiate treatment by the side of the body (left or right breast) and by the radiation type and energy. For example, code DM000ZZ represents beam radiation of the left breast using photons with energy less than 1 MeV, while DM014ZZ indicates use of heavy particles for the right breast. Some codes specify intraoperative electron beam radiation, such as DM003Z0. These detailed codes support precise documentation of the radiation therapy approach, essential for treatment planning and clinical records.

Questions About This Page

How many billable codes are in the DM0 range?

Of the 17 codes in this range, 16 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 DM0 range classify?

The range classifies Beam Radiation procedures, a type of radiation therapy that uses a machine to aim high-energy rays at the cancer from outside of the body, performed on the breast. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
