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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DD27 includes procedures performed to deliver stereotactic radiosurgery to tissues in the rectum. These ICD-10-PCS codes are used for inpatient documentation when stereotactic, high-precision radiation therapy is administered to treat rectal lesions or localized disease. Accurate coding within the ICD-10-PCS DD27 group is essential for proper inpatient reimbursement, as it captures the specific radiation procedure performed and supports clinical documentation accuracy.

Rectum Stereotactic Radiosurgery Procedure Overview

This procedure group includes stereotactic radiosurgery treatments directed at the rectum, targeting the gastrointestinal system with highly focused radiation beams. Procedures in this group deliver precise, high-dose radiation to rectal lesions while sparing surrounding tissues. Accurate ICD-10-PCS coding matters because it documents the specific radiation therapy delivered and supports appropriate inpatient reimbursement and clinical recordkeeping.

Typical Clinical Scenarios

An elderly patient with a solitary, well‑defined rectal metastasis from previously treated colorectal carcinoma is admitted for a planned, high‑precision, noninvasive ablative therapy because surgical resection would be high risk due to comorbidities; stereotactic delivery of focused photon beams is selected to maximize local control while sparing adjacent pelvic structures. Typical codes: DD27DZZ
A middle‑aged patient with a small, isolated rectal neuroendocrine tumor not amenable to endoscopic resection is admitted electively for stereotactic particulate radiosurgery as a tissue‑sparing alternative to surgery to achieve tumor ablation with minimal surrounding tissue dose. Typical codes: DD27HZZ
A patient with a recurrent rectal lesion previously treated with external beam radiation presents with painful local recurrence and is brought to the hospital for urgent, highly localized gamma‑beam stereotactic radiosurgery to control bleeding and focal progression while limiting additional dose to previously irradiated tissues. Typical codes: DD27JZZ
