ICD-10-PCS Code For Thyroid Gland: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BG24 includes procedures performed to image the thyroid gland using computerized tomography. These ICD-10-PCS codes are used for inpatient documentation when multiplanar reformatted digital images are produced from multiple external ionizing radiation exposures to evaluate thyroid structure or disease. Accurate coding within the ICD-10-PCS BG24 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Thyroid Gland Computerized Tomography Procedure Overview

This group includes computerized tomography procedures of the thyroid gland that produce reformatted multiplanar digital images from multiple exposures of external ionizing radiation. These procedures target the endocrine system and are used to evaluate thyroid anatomy, pathology, and surrounding structures. Accurate ICD-10-PCS coding ensures inpatient records reflect the imaging performed and supports appropriate inpatient reimbursement. Precise documentation of the operation and body part is essential for correct code assignment and payment determination.

Typical Clinical Scenarios

An elderly patient is admitted with rapidly enlarging neck mass, new dysphagia, and hoarseness raising concern for invasive thyroid malignancy or hemorrhage into a thyroid nodule; inpatient evaluation includes cross-sectional imaging to assess extent, tracheal compression, and local invasion prior to surgical planning, requiring reformatted multiplanar CT of the thyroid with and without contrast to delineate vascular involvement. Typical codes: BG2410Z, BG241ZZ
A middle-aged patient with acute neck pain, fever, and sepsis physiology after recent fine-needle aspiration presents for inpatient workup to evaluate for suppurative thyroiditis or abscess; contrast-enhanced CT with multiplanar reformats is performed to define fluid collection, guide potential drainage, and assess surrounding structures. Typical codes: BG2400Z, BG240ZZ
An inpatient with chronic multinodular goiter undergoing preoperative assessment after elective admission for planned thyroidectomy requires high-resolution CT to map nodules, retrosternal extension, and relation to vasculature; nonenhanced and contrast-enhanced reformatted CT images are obtained to inform operative approach. Typical codes: BG24Y0Z, BG24YZZ
