ICD-10-PCS Code For Lymphatics, Head And Neck: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C755 includes procedures performed to detect radioactive emissions using a nonimaging nuclear medicine probe in lymphatics of the head and neck. These ICD-10-PCS codes are used for inpatient documentation when radioactive tracers are introduced and a probe is used to study distribution or identify sentinel lymph nodes in the head and neck region. Accurate coding within the ICD-10-PCS C755 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy that determines appropriate case mix and payment.

Lymphatics, Head And Neck Nonimaging Nuclear Medicine Probe Procedure Overview

Procedures in this group involve introduction of radioactive materials and use of a nonimaging nuclear medicine probe to assess lymphatic structures of the head and neck. These procedures target the lymphatic and hematologic system to identify lymphatic drainage, sentinel nodes, or radioactive tracer localization. Accurate ICD-10-PCS coding ensures inpatient records reflect the nuclear medicine probe procedure performed and supports appropriate case mix and payment.

When to Use

Use these codes when a radioactive tracer is administered and a nonimaging nuclear medicine probe is used to detect emissions from lymphatic structures in the head and neck. These codes apply when the procedure is performed in the inpatient setting to identify lymphatic drainage patterns or sentinel lymph nodes.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
C7551ZZ	Nonimaging Nuclear Medicine Probe of Head and Neck Lymphatics using Technetium 99m (Tc-99m)
C755YZZ	Nonimaging Nuclear Medicine Probe of Head and Neck Lymphatics using Other Radionuclide

Typical Clinical Scenarios

An adult patient with a high-risk squamous cell carcinoma of the oral cavity is admitted for planned wide local excision and neck management; preoperative mapping of sentinel lymph nodes in the ipsilateral neck and peritumoral lymphatics of the head and neck is performed after injection of a technetium-99m radiotracer to identify nodes for selective dissection. A nonimaging nuclear medicine probe is used intraoperatively to localize radioactive sentinel nodes for targeted removal. Typical codes: C7551ZZ
An elderly patient with recurrent melanoma of the parotid region is admitted urgently due to clinically suspicious nodal disease; to delineate altered lymphatic drainage from prior surgery and guide selective node sampling during the inpatient operative session, a radiotracer is introduced and a nonimaging probe detects residual sentinel or aberrant nodes in the head and neck. The probe-guided detection aids limited dissection in a reoperative field to minimize morbidity. Typical codes: C755YZZ, C7551ZZ
A pediatric patient with a newly diagnosed papillary thyroid carcinoma is admitted for total thyroidectomy with intraoperative assessment of central compartment lymphatic drainage; a technetium-99m tracer is injected perioperatively and a nonimaging nuclear medicine probe is used to survey the central neck lymphatics to identify radioactive nodes for biopsy during the inpatient procedure. The technique helps determine need for compartmental node removal in the same admission. Typical codes: C7551ZZ
