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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DWY3 includes procedures performed to deliver other radiation therapies to anatomical regions in the abdomen. These ICD-10-PCS codes are used for inpatient documentation when a nonstandard or specialized form of radiation therapy is administered to treat disease processes located in the abdominal region. Accurate coding within the ICD-10-PCS DWY3 group is essential for proper inpatient reimbursement, as it captures the specific radiation procedure performed and supports clinical documentation accuracy.

Abdomen Other Radiation Procedure Overview

This procedure group includes inpatient other radiation therapies directed at the abdomen and surrounding anatomical regions, targeting anatomical regions in the body system. These procedures deliver nonstandard or specialized radiation modalities to treat conditions involving abdominal structures. Accurate ICD-10-PCS coding of these radiation procedures ensures the inpatient record reflects the therapy provided and supports appropriate reimbursement and clinical documentation integrity.

When to Use

Use a code from this group when a patient receives a nonstandard or specialized radiation therapy targeted to abdominal anatomical regions during an inpatient stay. Codes are selected when the documented procedure indicates other radiation as the operation and the body part is the abdomen.

ICD-10-PCS Code	Description
DWY37ZZ	Contact Radiation of Abdomen
DWY38ZZ	Hyperthermia of Abdomen
DWY3FZZ	Plaque Radiation of Abdomen

Typical Clinical Scenarios

An elderly patient with locally advanced hepatocellular carcinoma causing pain and limited options after failed systemic therapy is admitted for inpatient palliative control of abdominal tumor burden; multidisciplinary team elects a localized, nonstandard radiation modality delivered directly to the tumor surface to reduce pain and tumor progression while minimizing exposure to surrounding organs. Typical codes: DWY37ZZ, DWY3FZZ
A middle-aged patient with recurrent abdominal wall melanoma metastasis undergoes a planned inpatient procedure to apply regional hyperthermia combined with localized radiation when conventional external beam therapy is contraindicated due to prior dose limits; the intent is to enhance radiation sensitivity of the tumor within the abdominal region during a scheduled admission. Typical codes: DWY38ZZ
A postoperative patient develops a solitary pelvic/abdominal tumor deposit adjacent to surgical hardware where standard external beam fields would risk hardware damage; during the inpatient stay a contact or plaque-based radiation approach is chosen to directly treat the abdominal lesion while sparing surrounding structures and addressing the complication of prior surgery. Typical codes: DWY37ZZ, DWY3FZZ
