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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DW22 includes procedures performed to deliver targeted stereotactic radiosurgery to structures in the chest. These ICD-10-PCS codes are used for inpatient documentation when stereotactic radiosurgery is performed for precise, high-dose radiation treatment of thoracic tumors or lesions. Accurate coding within the ICD-10-PCS DW22 group is essential for proper inpatient reimbursement, as it captures the specialized radiation therapy delivered and supports clinical documentation accuracy.

Chest Stereotactic Radiosurgery Procedure Overview

This procedure group includes stereotactic radiosurgery treatments targeted to the chest anatomical region, focusing on precise radiation delivery to thoracic tumors and lesions within the chest. These procedures involve highly focused, image-guided radiation aimed at chest structures while minimizing dose to surrounding tissues and organs. Accurate ICD-10-PCS coding of these stereotactic radiosurgery procedures ensures correct inpatient documentation and supports appropriate reimbursement for complex radiation therapy services.

Typical Clinical Scenarios

An elderly patient with a solitary, medically inoperable early-stage non–small cell lung cancer presents for definitive high‑dose focal treatment after multidisciplinary review; the patient is admitted for planned image‑guided stereotactic radiosurgery to ablate the thoracic tumor while minimizing dose to surrounding lung and mediastinal structures. Typical codes: DW22DZZ, DW22JZZ
A middle‑aged patient with a small-volume metastatic lesion to the chest wall causing refractory pain and chest wall instability is admitted for urgent palliative stereotactic radiosurgery to provide rapid tumor control and pain relief while preserving adjacent vital structures. Typical codes: DW22HZZ, DW22DZZ
A patient with a previously irradiated central pulmonary lesion develops a radioresistant nodule identified on surveillance imaging and is admitted for a salvage, highly conformal stereotactic radiosurgery session directed at the chest lesion to achieve local control while limiting cumulative dose to critical thoracic organs. Typical codes: DW22JZZ, DW22DZZ
