ICD-10-PCS Code For Breasts, Bilateral: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BH32 includes procedures performed to image breast structures in the bilateral breasts. These ICD-10-PCS codes are used for inpatient documentation when magnetic resonance imaging of the breasts is performed for diagnostic evaluation or treatment planning. Accurate coding within the ICD-10-PCS BH32 group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Breasts Magnetic Resonance Imaging Procedure Overview

This procedure group includes magnetic resonance imaging examinations of the bilateral breasts and targets the skin, subcutaneous tissue, and breast structures. These procedures involve capturing radiofrequency signals in a magnetic field to produce reformatted multiplanar digital images for diagnostic evaluation. Accurate ICD-10-PCS coding of these imaging procedures ensures correct inpatient documentation and supports appropriate reimbursement for imaging services.

When to Use

Use codes from this group when inpatient magnetic resonance imaging of both breasts is performed for diagnostic evaluation, staging, or treatment planning. Select the code that reflects the bilateral breast MRI procedure and any specific imaging technique documented in the operative or procedure report.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
BH32Y0Z	Magnetic Resonance Imaging (MRI) of Bilateral Breasts using Other Contrast, Unenhanced and Enhanced
BH32YZZ	Magnetic Resonance Imaging (MRI) of Bilateral Breasts using Other Contrast
BH32ZZZ	Magnetic Resonance Imaging (MRI) of Bilateral Breasts

Typical Clinical Scenarios

A middle-aged woman admitted for inpatient workup after presentation with a rapidly enlarging palpable mass in both breasts and suspicious bilateral findings on mammogram and ultrasound; inpatient breast MRI is ordered to better characterize lesion extent, assess multicentric disease, and assist surgical planning for potential bilateral mastectomy or lumpectomy. Typical codes: BH32ZZZ.
A patient with a known history of bilateral breast cancer hospitalized for staging and treatment planning before systemic therapy; contrast-enhanced MRI of both breasts is performed to evaluate tumor size, multifocality, and response prediction, using a specific contrast protocol documented as “other contrast” in the imaging report. Typical codes: BH32Y0Z, BH32YZZ.
An inpatient with prior bilateral breast conserving surgery who develops ambiguous postoperative changes and suspected recurrent disease on clinical exam and ultrasound; an MRI of both breasts is obtained to differentiate scar from recurrence and to guide possible re-excision or further therapy. Typical codes: BH32ZZZ, BH32YZZ
