ICD-10-PCS Code For Lymphatics, Upper Chest: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C75L includes procedures performed to introduce radioactive materials and detect emissions using a nonimaging nuclear medicine probe in the lymphatics of the upper chest. These ICD-10-PCS codes are used for inpatient documentation when a nonimaging nuclear medicine probe procedure is performed to evaluate lymphatic distribution or sentinel lymph node localization in the upper chest. Accurate coding within the ICD-10-PCS C75L group is essential for proper inpatient reimbursement, as it captures the specific nuclear medicine probe procedure performed and supports clinical documentation accuracy.

Lymphatics, Upper Chest Nonimaging Nuclear Medicine Probe Procedure Overview

Procedures in this group involve introduction of radioactive materials and use of a nonimaging nuclear medicine probe to study lymphatic structures in the upper chest and related lymphatic and hematologic system. These procedures target the lymphatics of the upper chest to detect radioactive emissions and trace distribution or drainage patterns. Accurate ICD-10-PCS coding of these procedures supports appropriate inpatient reimbursement by capturing the specific diagnostic nuclear medicine probe procedure performed and linking it to clinical documentation.

Code Attributes

Character	ICD-10-PCS Category	Code Group Details
C	Section	Nuclear Medicine
7	Body System	Lymphatic and Hematologic System
5	Operation	Nonimaging Nuclear Medicine Probe
L	Body Part	Lymphatics, Upper Chest

When to Use

Use a code from this group when a nonimaging nuclear medicine probe is employed after introducing radioactive material to the lymphatics of the upper chest for diagnostic tracing or sentinel node localization. Codes apply when inpatient documentation specifies the operation as nonimaging nuclear medicine probe targeting the upper chest lymphatics.

ICD-10-PCS Code	Description
C75L1ZZ	Nonimaging Nuclear Medicine Probe of Upper Chest Lymphatics using Technetium 99m (Tc-99m)
C75LYZZ	Nonimaging Nuclear Medicine Probe of Upper Chest Lymphatics using Other Radionuclide

Typical Clinical Scenarios

A 62-year-old woman admitted for staging of newly diagnosed upper chest/central breast malignancy with palpable axillary and supraclavicular nodes. A radiopharmaceutical (Tc-99m) is injected to map lymphatic drainage and localize sentinel lymph nodes in the upper chest region prior to planned surgical excision; a nonimaging nuclear medicine probe is used intraoperatively to detect radioactive emissions and guide node retrieval. The procedure aids in accurate staging and directs definitive surgical management during the inpatient stay. Typical codes: C75L1ZZ
A 49-year-old man presents emergently with a rapidly enlarging, tender supraclavicular mass suspicious for metastatic disease. After initial evaluation, a nonimaging nuclear medicine probe procedure is performed following injection of a radiotracer to identify lymphatic drainage patterns and sentinel nodes in the upper chest to target biopsy while the patient is admitted for expedited diagnostic workup. The localization assists the surgical team in obtaining representative nodes for pathology during the same inpatient encounter. Typical codes: C75L1ZZ
A 70-year-old woman with prior breast-conserving surgery and prior lymphatic mapping presents for re-exploration due to recurrent regional nodal disease in the upper chest after previous surgery. Repeat lymphatic mapping is performed using a nonimaging probe with a non-technetium radionuclide because of prior tracer allergy or altered tracer availability, to localize current sentinel or involved nodes for targeted removal during the inpatient revision procedure. This assists in directing salvage surgical therapy while accounting for prior operative changes. Typical codes: C75LYZZ
