ICD-10-PCS Code For Ovaries Bilateral: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BU35 includes procedures performed to image the ovaries, bilateral using magnetic resonance imaging. These ICD-10-PCS codes are used for inpatient documentation when magnetic resonance imaging of both ovaries is performed for diagnostic evaluation or preoperative assessment. Accurate coding within the ICD-10-PCS BU35 group is essential for proper inpatient reimbursement, as it captures the diagnostic imaging performed and supports clinical documentation accuracy.

Ovaries, Bililateral Magnetic Resonance Imaging Procedure Overview

This procedure group includes magnetic resonance imaging studies of the bilateral ovaries within the female reproductive system. Procedures use radiofrequency signals in a magnetic field to generate multiplanar digital images for diagnosis and treatment planning. Accurate ICD-10-PCS reporting of these imaging procedures ensures inpatient records reflect the diagnostic services provided and supports correct case mix and payment.

ICD-10-PCS Code	Description
BU35Y0Z	Magnetic Resonance Imaging (MRI) of Bilateral Ovaries using Other Contrast, Unenhanced and Enhanced
BU35YZZ	Magnetic Resonance Imaging (MRI) of Bilateral Ovaries using Other Contrast
BU35ZZZ	Magnetic Resonance Imaging (MRI) of Bilateral Ovaries

Typical Clinical Scenarios

A premenopausal woman is admitted for acute pelvic pain and suspected ovarian torsion after severe unilateral lower abdominal pain and nausea; clinical exam and ultrasound are inconclusive for bilateral adnexal involvement, and inpatient MRI is ordered to evaluate both ovaries for ischemia, mass, or torsion before urgent surgical decision-making. Typical codes: BU35ZZZ
An elective inpatient workup for a patient with a known bilateral ovarian neoplasm identified on outpatient imaging who is admitted for planned surgical staging; high-resolution MRI of both ovaries with and without contrast is performed to delineate tumor extent, ovarian involvement, and pelvic anatomy to guide the operative approach. Typical codes: BU35Y0Z, BU35YZZ
A patient hospitalized for worsening pelvic pain and fever after pelvic surgery with concern for bilateral ovarian abscesses or complex adnexal collections; MRI of the bilateral ovaries is obtained to characterize multiloculated fluid collections, assess for enhancement patterns, and help determine need for interventional drainage versus continued medical therapy. Typical codes: BU35YZZ, BU35ZZZ
