ICD-10-PCS Code For Colon: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DD05 includes procedures performed to deliver beam radiation to the colon. These ICD-10-PCS codes are used for inpatient documentation when patients receive therapeutic external or internal beam radiation targeting colon tissue. Accurate coding within the ICD-10-PCS DD05 group is essential for proper inpatient reimbursement, as it captures procedure performed and supports clinical documentation accuracy.

Colon Beam Radiation Procedure Overview

This procedure group includes beam radiation treatments directed at the colon within the gastrointestinal system. Procedures in this group involve delivery of targeted ionizing radiation beams to colon tissue for therapeutic purposes. Accurate ICD-10-PCS coding of these radiation therapy procedures is important for inpatient documentation and reimbursement because it captures the specific operation, body system, and treatment intent.

When to Use

Use a code from this group when a patient receives beam radiation directed at the colon as part of inpatient treatment. These codes apply when the operation performed is beam radiation and the anatomical target is the colon.

ICD-10-PCS Code	Description
DD050ZZ	Beam Radiation of Colon using Photons <1 MeV
DD051ZZ	Beam Radiation of Colon using Photons 1 - 10 MeV
DD052ZZ	Beam Radiation of Colon using Photons >10 MeV
DD053Z0	Beam Radiation of Colon using Electrons, Intraoperative
DD053ZZ	Beam Radiation of Colon using Electrons
DD054ZZ	Beam Radiation of Colon using Heavy Particles (Protons,Ions)
DD055ZZ	Beam Radiation of Colon using Neutrons
DD056ZZ	Beam Radiation of Colon using Neutron Capture

Typical Clinical Scenarios

An elderly patient with locally advanced colon adenocarcinoma is admitted for inpatient coordination of multidisciplinary therapy including fractionated external beam radiation to reduce tumor burden before planned surgery. The radiation oncology team delivers high-energy photon beams in multiple fractions targeting the colon tumor to provide tumor cytoreduction while inpatient support is available for symptom management. A code corresponding to photon beam radiation at the appropriate energy is selected to reflect delivery of external beam therapy to colon tissue. Typical codes: DD051ZZ, DD052ZZ
A middle-aged patient presents with acute symptomatic bleeding from a recurrent rectosigmoid colon tumor requiring urgent inpatient management; after stabilization, intraoperative electron beam radiation is delivered at the time of a palliative surgical procedure to control local disease and bleeding. Because the electron beam was applied during the operative session to the colon lesion, the intraprocedural electron beam radiation code is appropriate. Typical codes: DD053Z0
A younger adult with metastatic colon cancer who previously received external photon radiation develops a radioresistant lesion and is admitted for a targeted particle therapy session using protons to treat persistent disease while inpatient for close monitoring of side effects. The procedure involves delivery of heavy particle beam radiation directed at colon tissue to attempt improved local control after prior photon therapy. Typical codes: DD054ZZ
