ICD-10-PCS Code For Bile Ducts: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DF02 includes procedures performed to irradiate tissues in the bile ducts. These ICD-10-PCS codes are used for inpatient documentation when beam radiation therapy is delivered to the bile ducts for treatment of malignant or other pathological conditions. Accurate coding within the ICD-10-PCS DF02 group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Bile Ducts Beam Radiation Procedure Overview

This code group covers beam radiation procedures delivered to the bile ducts within the hepatobiliary system and pancreas. These procedures involve directing external or internal beam radiation to treat malignant or other abnormal tissue of the bile ducts. Accurate coding of these beam radiation procedures ensures inpatient records reflect the therapeutic modality and target, which affects case mix group assignment and reimbursement.

When to Use

Use a code from this group when beam radiation therapy is intentionally directed at the bile ducts as part of inpatient treatment. Codes should be assigned when documentation specifies beam radiation as the operative modality and the bile ducts are the anatomical target.

ICD-10-PCS Code	Description
DF020ZZ	Beam Radiation of Bile Ducts using Photons <1 MeV
DF021ZZ	Beam Radiation of Bile Ducts using Photons 1 - 10 MeV
DF022ZZ	Beam Radiation of Bile Ducts using Photons >10 MeV
DF023Z0	Beam Radiation of Bile Ducts using Electrons, Intraoperative
DF023ZZ	Beam Radiation of Bile Ducts using Electrons
DF024ZZ	Beam Radiation of Bile Ducts using Heavy Particles (Protons,Ions)
DF025ZZ	Beam Radiation of Bile Ducts using Neutrons
DF026ZZ	Beam Radiation of Bile Ducts using Neutron Capture

Typical Clinical Scenarios

An elderly patient with unresectable cholangiocarcinoma presents for planned inpatient administration of external beam radiation to palliate obstructive jaundice and control local tumor growth; inpatient admission is for fractionated radiation planning and delivery with close monitoring for hepatic or biliary complications. Typical codes: DF022ZZ, DF024ZZ
A middle-aged patient with locally recurrent bile duct carcinoma after prior surgery is admitted electively for intraoperative electron beam radiation delivered at the time of re-exploration to treat microscopic residual disease at the biliary margin. Typical codes: DF023Z0, DF023ZZ
A patient with progressive malignant biliary obstruction and prior high-energy photon therapy is admitted urgently for targeted neutron capture therapy as part of salvage inpatient treatment when conventional photons are insufficient, necessitating specialized beam modality selection. Typical codes: DF026ZZ, DF025ZZ
