Procedures remove all of a specified lymphatic body part in the thorax without replacement. Accurate ICD-10-PCS coding of these resections is important for inpatient reimbursement because it documents the exact operation and anatomic site, which affects case mix and payment.

Typical Clinical Scenarios

A middle-aged patient with known non-Hodgkin lymphoma presents for planned staging and therapeutic management after imaging shows a solitary bulky mediastinal lymph node mass suspicious for malignancy. The patient is admitted for an elective open surgical resection of the entire affected thoracic lymph node group to obtain definitive pathology and to reduce mass effect on adjacent structures; complete removal without replacement is documented. Typical codes: 07T70ZZ
An elderly patient develops progressive shortness of breath and recurrent pleural effusions; workup reveals a symptomatic symptomatic intrathoracic lymphatic conglomerate causing compressive symptoms and recurrent chylous leakage despite conservative measures. The patient is taken to the operating room for an open resection of the diseased thoracic lymphatic tissue to control symptoms and resolve the chyle leak, requiring inpatient postoperative care. Typical codes: 07T70ZZ
A younger patient with a history of thoracic malignancy underwent prior mediastinal procedures and now has a persistent infected lymphatic mass with fistula formation after failed percutaneous drainage. After stabilization, the patient requires a percutaneous endoscopic approach to resect the remaining thoracic lymphatic tissue causing ongoing infection, performed during an inpatient admission for source control and recovery. Typical codes: 07T74ZZ
