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 0GJK includes procedures performed to inspect structures in the thyroid gland. These ICD-10-PCS codes are used for inpatient documentation when a clinician performs visual or manual exploration of the thyroid gland to evaluate its condition.

Thyroid Gland Inspection Procedure Overview

This procedure group includes visually and/or manually exploring the thyroid gland within the endocrine system to inspect its condition and identify abnormalities. Procedures involve direct or indirect visualization and manual palpation of the gland and surrounding structures to assess size, texture, nodules, and other findings. Accurate ICD-10-PCS coding of these inspection procedures is important for inpatient reimbursement because it documents the specific clinical service provided and supports appropriate case mix and payment.

Typical Clinical Scenarios

An elderly patient is admitted with rapidly enlarging neck mass, progressive dysphagia and hoarseness raising concern for acute thyroid enlargement or hemorrhage into a thyroid nodule. Inpatient evaluation includes direct visual and manual inspection of the gland during a surgical exploration to assess extent, consistency, and presence of necrosis or hematoma before definitive management; inspection guides urgent operative decision-making. Typical codes: 0GJK0ZZ
A middle-aged patient with a history of multinodular goiter is scheduled for an inpatient diagnostic procedure because outpatient imaging was inconclusive and palpable nodules are changing in size; the team performs a percutaneous, image-assisted palpation and inspection to document surface characteristics and to determine need for further surgical excision. Typical codes: 0GJK3ZZ, 0GJK4ZZ
A postoperative inpatient returns with concern for suspected wound-related thyroid abnormality after prior neck surgery; during re-exploration under anesthesia the clinician visually inspects and manually explores the thyroid bed to evaluate for residual gland, recurrent nodules, or scar tissue affecting function and to plan any corrective step. Typical codes: 0GJK0ZZ
