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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DTY1 includes procedures performed to irradiate or otherwise deliver therapeutic radiation to the ureter in the urinary system. These ICD-10-PCS codes are used for inpatient documentation when therapeutic radiation is targeted specifically to the ureter to treat malignant or other localized conditions. Accurate coding within the ICD-10-PCS DTY1 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Ureter Other Radiation Procedure Overview

This procedure group includes other radiation procedures directed at the ureter within the urinary system. These procedures involve delivering therapeutic radiation to the ureter to treat malignant or other pathological conditions while minimizing exposure to surrounding urinary structures. Accurate ICD-10-PCS coding of these radiation procedures ensures inpatient documentation reflects the specific body part and operation, which supports correct reimbursement and clinical record integrity.

When to Use

Use codes from this group when the primary procedure performed is therapeutic radiation directed at the ureter. Select these codes when inpatient documentation indicates radiation was administered specifically to the ureter rather than to adjacent urinary structures or systemic therapy.

ICD-10-PCS Codes

4 rows

ICD-10-PCS Code	Description
DTY17ZZ	Contact Radiation of Ureter
DTY18ZZ	Hyperthermia of Ureter
DTY1CZZ	Intraoperative Radiation Therapy (IORT) of Ureter
DTY1FZZ	Plaque Radiation of Ureter

Typical Clinical Scenarios

An elderly patient with a localized ureteral carcinoma causing obstructive symptoms is admitted for planned definitive local therapy after multidisciplinary review; imaging confirms a solitary lesion confined to the ureter without distant metastasis, and the team elects a targeted intraoperative adjunct to maximize local control during a scheduled surgical resection. A focused radiation procedure is performed directly to the ureter at the time of surgery to deliver concentrated dose while sparing surrounding urinary structures. Typical codes: DTY1CZZ
A middle-aged patient with recurrent superficial ureteral tumor after prior endoscopic resections presents for elective organ-preserving treatment to avoid nephroureterectomy; because the lesion is accessible endoluminally, a localized contact radiation approach is used to ablate the ureteral tumor and reduce risk of further recurrence. Typical codes: DTY17ZZ
A patient with an incompletely resected or radioresistant ureteral lesion develops a residual localized tumor causing pain and hematuria and is admitted urgently for palliative, high-dose localized therapy; plaque or hyperthermia-assisted radiation is applied to the ureter to achieve symptom control and local tumor cytoreduction in the inpatient setting. Typical codes: DTY1FZZ, DTY18ZZ
