ICD-10-PCS Code For Adrenal Glands: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BG42 includes procedures performed to image and evaluate anatomy and flow information of the adrenal glands using ultrasonography. These ICD-10-PCS codes are used for inpatient documentation when real-time ultrasonographic evaluation of both adrenal glands is performed to diagnose or monitor adrenal pathology. Accurate coding within the ICD-10-PCS BG42 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Adrenal Glands Ultrasonography Procedure Overview

This procedure group includes real-time imaging using high-frequency sound waves to visualize the adrenal glands and assess their anatomy and blood flow. The procedures target the endocrine system and specifically the bilateral adrenal glands. Accurate ICD-10-PCS coding ensures inpatient records reflect the imaging performed and supports appropriate case mix assignment and reimbursement.

ICD-10-PCS Code	Description
BG42ZZZ	Ultrasonography of Bilateral Adrenal Glands

Typical Clinical Scenarios

A middle-aged patient is admitted with acute onset abdominal pain and hypotension after blunt torso trauma. Concern for adrenal hemorrhage and bilateral adrenal injury prompts real-time ultrasonographic evaluation of both adrenal glands to assess for masses, bleeding, and altered vascular flow as part of the inpatient diagnostic workup. Typical codes: BG42ZZZ
An inpatient endocrine service requests imaging for a hospitalized patient with newly diagnosed Cushingoid features and biochemical evidence of hypercortisolism. A planned inpatient bilateral adrenal ultrasonography is performed to visualize gland size and architecture and to assist in localizing bilateral adrenal hyperplasia versus nodular disease as part of the evaluation prior to further management. Typical codes: BG42ZZZ
A patient is admitted for worsening flank pain and anemia several days after anticoagulation initiation; clinicians suspect delayed bilateral adrenal hemorrhage as a complication. Real-time ultrasonography of both adrenal glands is obtained to detect hemorrhage, monitor progression, and guide ongoing inpatient management decisions. Typical codes: BG42ZZZ
