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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group CW5B includes procedures performed to introduce radioactive materials and detect radioactive emissions in the head and neck anatomical region. These ICD-10-PCS codes are used for inpatient documentation when nonimaging nuclear medicine probe techniques are performed to study distribution or measure absorption of radioactive substances in head and neck structures. Accurate coding within the ICD-10-PCS CW5B group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Head And Neck Nonimaging Nuclear Medicine Probe Procedure Overview

This procedure group includes introduction of radioactive materials and nonimaging probe techniques targeting the head and neck anatomical region. Procedures involve placing a probe or introducing radiopharmaceuticals to detect radioactive emissions or measure absorption related to head and neck structures within the nuclear medicine section. Accurate ICD-10-PCS coding ensures inpatient records reflect the specific nonimaging nuclear medicine probe procedures and supports correct case classification and reimbursement.

B	Body Part	Head and Neck

When to Use

Use codes from this group when a nonimaging nuclear medicine probe procedure is performed on head and neck structures to detect radioactive emissions or measure uptake. These codes apply when radiopharmaceuticals are introduced or when absorption of externally applied radioactive sources is measured in the head and neck.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
CW5B1ZZ	Nonimaging Nuclear Medicine Probe of Head and Neck using Technetium 99m (Tc-99m)
CW5BDZZ	Nonimaging Nuclear Medicine Probe of Head and Neck using Indium 111 (In-111)
CW5BYZZ	Nonimaging Nuclear Medicine Probe of Head and Neck using Other Radionuclide

Typical Clinical Scenarios

An elderly patient is admitted with acute epistaxis refractory to anterior and posterior packing. The otolaryngology team suspects a vascular lesion supplied by branches in the nasal cavity and uses a nonimaging nuclear medicine probe after administration of a technetium-labeled tracer to localize active bleeding sites within the head and neck before endoscopic intervention. Nonimaging probe detection with Technetium 99m helps guide the surgical team to the bleeding source during the inpatient stay. Typical codes: CW5B1ZZ
A middle-aged patient with a history of thyroid cancer is admitted for planned evaluation of suspected recurrent disease in the neck. After administration of a technetium-based radiopharmaceutical, nonimaging probe measurements over thyroid bed and cervical lymph node regions are performed to assess radiotracer uptake and guide further surgical planning or inpatient workup. The procedure is scheduled during the inpatient admission as part of the comprehensive recurrent disease assessment. Typical codes: CW5B1ZZ
A patient with a prior complex head and neck reconstruction presents with new-onset focal pain and a palpable mass near the surgical site suspicious for infection versus residual tumor. Because metallic reconstruction hardware limits conventional imaging and precise localization is required, an indium-111 labeled radiopharmaceutical is introduced and a nonimaging nuclear medicine probe is used at the bedside to detect focal radiotracer accumulation in the head and neck region to help distinguish inflammatory uptake from recurrent malignancy.
