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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DFY1 includes procedures performed to deliver other radiation to structures in the gallbladder. These ICD-10-PCS codes are used for inpatient documentation when radiation therapy is directed at the gallbladder or adjacent hepatobiliary structures as part of treatment. Accurate coding within the ICD-10-PCS DFY1 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Gallbladder Other Radiation Procedure Overview

Procedures in this group involve delivery of radiation therapy targeted to the gallbladder and surrounding hepatobiliary structures. These interventions are performed within the Radiation Therapy section of the International Classification of Diseases, Tenth Revision, Procedure Coding System and focus on other radiation operations rather than excision or destruction. Accurate ICD-10-PCS coding of these procedures supports appropriate inpatient reimbursement by reflecting the clinical treatment delivered to the hepatobiliary system.

When to Use

Use codes from this group when a patient receives other radiation therapy specifically targeted to the gallbladder or adjacent hepatobiliary structures during an inpatient stay. Select the appropriate ICD-10-PCS code when documentation indicates radiation was delivered to the gallbladder as the anatomical site of treatment.

ICD-10-PCS Code	Description

Typical Clinical Scenarios

An elderly patient with locally advanced gallbladder carcinoma causing pain and biliary obstruction is admitted for inpatient multimodal therapy after staging demonstrates localized tumor without distant metastasis. As part of the planned inpatient treatment to control tumor growth and palliate symptoms, contact radiation is delivered directly to the gallbladder mass under imaging guidance to concentrate dose to the lesion while minimizing exposure to surrounding liver tissue. This targeted radiation is chosen to provide local tumor control in a frail patient who is a poor candidate for extensive surgery. Typical codes: DFY17ZZ
A middle-aged patient presents emergently with bleeding from a recurrent gallbladder tumor discovered during an inpatient workup; surgical resection is not feasible because of tumor location and patient comorbidities. Intraoperative assessment during a planned operative procedure leads the team to deliver intraoperative radiation therapy focused on the gallbladder region to achieve local hemostasis and immediate high-dose focal treatment to the tumor bed. This single-fraction intraoperative radiation is used to maximize local control when other definitive options are limited. Typical codes: DFY1CZZ
A younger adult with a history of prior liver-directed therapies is admitted for management of a symptomatic, superficial metastatic deposit involving the gallbladder serosa causing localized pain. Given the superficial nature of the lesion and desire to limit deeper tissue exposure, plaque radiation is applied to the gallbladder surface during an inpatient procedure to deliver localized radiation while sparing adjacent hepatic parenchyma. This approach is selected to control focal disease and alleviate symptoms in a patient with limited metastatic burden. Typical codes: DFY1FZZ
