ICD-10-PCS Code For Gastrointestinal Tract: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DW1P includes procedures performed to deliver brachytherapy to tissues in the gastrointestinal tract. These ICD-10-PCS codes are used for inpatient documentation when internal radiation sources are placed temporarily or permanently within the gastrointestinal tract for therapeutic intent. Accurate coding within the ICD-10-PCS DW1P group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Gastrointestinal Tract Brachytherapy Procedure Overview

Procedures in this group involve delivery of internal radiation directly to the gastrointestinal tract using brachytherapy techniques to treat malignant and selected benign lesions. These procedures target anatomical regions of the gastrointestinal tract and are coded in the Radiation Therapy section of the International Classification of Diseases, Tenth Revision, Procedure Coding System. Accurate coding ensures the inpatient record reflects the targeted internal radiation treatment and supports appropriate reimbursement and clinical documentation integrity.

When to Use

Use a code from this group when internal radiation sources are intentionally placed within the gastrointestinal tract for treatment. Codes are applied for inpatient documentation of brachytherapy delivery to gastrointestinal tract sites.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
DW1PBB1	Low Dose Rate (LDR) Brachytherapy of Gastrointestinal Tract using Palladium 103 (Pd-103), Unidirectional Source
DW1PBBZ	Low Dose Rate (LDR) Brachytherapy of Gastrointestinal Tract using Palladium 103 (Pd-103)

Typical Clinical Scenarios

An elderly patient with a localized, obstructing rectal adenocarcinoma admitted for planned inpatient multimodality therapy when tumor-directed internal radiation is selected to deliver a concentrated dose while minimizing exposure to adjacent organs; brachytherapy catheters or unidirectional seeds are placed endoluminally during a scheduled hospital admission to provide targeted tumor control as part of definitive or preoperative treatment. Typical codes: DW1PBB1, DW1PBBZ
A middle-aged patient with a recurrent esophageal cancer previously treated with external beam radiation presents electively for salvage local therapy to control a symptomatic intraluminal lesion; during the inpatient procedure, low-dose-rate radioactive palladium-103 sources are implanted into the esophageal wall to deliver focal internal radiation while limiting further external-beam toxicity. Typical codes: DW1PBB1, DW1PBBZ
A patient hospitalized for management of severe gastrointestinal bleeding from a tumor where focal control is required after endoscopic measures fail; low-dose-rate brachytherapy is performed during the inpatient stay by placing palladium-103 sources into or adjacent to the bleeding tumor to achieve local hemostasis and tumor control when other interventions are insufficient. Typical codes: DW1PBBZ, DW1PBB1
