ICD-10-PCS Code For Lymphatics Trunk: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C75M includes procedures performed to introduce radioactive materials and detect emissions in lymphatics of the trunk. These ICD-10-PCS codes are used for inpatient documentation when nonimaging nuclear medicine probe techniques are used to assess distribution and fate of radioactive tracers in trunk lymphatic structures. Accurate coding within the ICD-10-PCS C75M group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Lymphatics, Trunk Nonimaging Nuclear Medicine Probe Procedure Overview

This procedure group includes introduction of radioactive materials for nonimaging probe assessment of lymphatics in the trunk and related hematologic structures. Procedures use nuclear medicine techniques to detect radioactive emissions from tracers placed in or near trunk lymphatic vessels and nodes. These procedures target the lymphatic and hematologic system and accurate ICD-10-PCS coding ensures inpatient documentation reflects the specific nuclear medicine probe procedure performed for reimbursement and clinical records.

C	Section	Nuclear Medicine
7	Body System	Lymphatic and Hematologic System
5	Operation	Nonimaging Nuclear Medicine Probe
M	Body Part	Lymphatics, Trunk

When to Use

Use a code from this group when a radioactive tracer is introduced and a nonimaging nuclear medicine probe is used to detect emissions from lymphatics in the trunk. These codes apply when the procedure is performed in the inpatient setting to assess lymphatic mapping, sentinel node identification, or tracer distribution in trunk lymphatic structures.

ICD-10-PCS Code	Description
C75M1ZZ	Nonimaging Nuclear Medicine Probe of Trunk Lymphatics using Technetium 99m (Tc-99m)
C75MYZZ	Nonimaging Nuclear Medicine Probe of Trunk Lymphatics using Other Radionuclide

Typical Clinical Scenarios

An adult patient admitted urgently with a large melanoma on the anterior chest wall requiring inpatient sentinel lymph node mapping prior to wide local excision. A technetium-99m radiotracer is injected peri-tumorally and a nonimaging nuclear medicine probe is used intraoperatively to localize radioactive sentinel trunk lymph nodes for targeted sampling. The procedure guides node selection without imaging to determine nodal involvement. Typical codes: C75M1ZZ
An elderly inpatient with recurrent breast cancer in the mastectomy bed scheduled electively for surgical excision and planned lymphatic mapping to identify residual sentinel nodes. Preoperative injection of a radiocolloid other than Tc-99m is performed with detection using a bedside nonimaging probe to locate tracer-avid trunk lymphatics for intraoperative biopsy. Typical codes: C75MYZZ
A hospitalized patient with postoperative lymphatic leak after chest-wall lymph node dissection where prior sentinel node mapping was inconclusive; repeat nonimaging probe assessment is performed with Tc-99m to re-evaluate trunk lymphatic drainage pathways to target re-exploration. The study is done inpatient to guide revision surgery and address the complication of persistent lymphatic drainage. Typical codes: C75M1ZZ
