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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DDY8 includes procedures performed to administer other radiation to structures in the anus. These ICD-10-PCS codes are used for inpatient documentation when patients require therapeutic radiation targeting anorectal disease as part of their hospital stay. Accurate coding within the ICD-10-PCS DDY8 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Anus Other Radiation Procedure Overview

Procedures in this group involve delivery of targeted other radiation therapy to the anus within the gastrointestinal system. These inpatient procedures are performed to address malignant or other pathological conditions of the anorectal region and involve technical and dosimetric considerations specific to pelvic anatomy. Accurate ICD-10-PCS coding of these procedures supports correct clinical documentation and influences inpatient payment through appropriate procedure capture.

When to Use

Use a code from this group when inpatient radiation therapy is delivered specifically to the anus for treatment of malignant or other pathological conditions. Select the code when the medical record documents administration of other radiation techniques targeted to anal anatomy during the inpatient encounter.

ICD-10-PCS Code	Description
DDY8CZZ	Intraoperative Radiation Therapy (IORT) of Anus
DDY8FZZ	Plaque Radiation of Anus

Typical Clinical Scenarios

An elderly patient admitted from the emergency department with a large, bleeding squamous cell carcinoma of the anal canal causing pain and local tissue invasion. After stabilization and multidisciplinary review, a single-session intraoperative radiation treatment is planned during a staged surgical procedure to deliver a concentrated dose directly to the tumor bed while minimizing exposure to surrounding pelvic tissues. The focused intraoperative radiation is performed in the inpatient setting to optimize local control and palliation of symptoms. Typical codes: DDY8CZZ
A middle-aged patient with biopsy-proven localized melanoma of the anal verge is admitted electively for definitive local therapy. As part of the planned treatment strategy to preserve anorectal function and avoid extensive resection, plaque radiation is placed adjacent to the lesion under anesthesia to deliver targeted radiation over a controlled time period. The inpatient procedure provides dosimetric control and monitoring for potential immediate post-placement issues. Typical codes: DDY8FZZ
A patient previously treated with external beam radiotherapy for anal cancer presents with a recurrent, painful nodular lesion at the prior resection margin and poor healing. During a readmission for management of recurrent disease and wound complications, intraoperative targeted radiation is delivered to the recurrent focus at the time of surgical debridement to attempt local control while limiting additional pelvic radiation exposure. The combined operative and intraoperative radiation approach addresses recurrence and aims to reduce further soft tissue compromise. Typical codes: DDY8CZZ
