ICD-10-PCS Code For Pregnant Uterus: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BU3B includes procedures performed to image the pregnant uterus in the female reproductive system. These ICD-10-PCS codes are used for inpatient documentation when magnetic resonance imaging is performed to evaluate the pregnant uterus during pregnancy for diagnostic assessment or monitoring. Accurate coding within the ICD-10-PCS BU3B group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Pregnant Uterus Magnetic Resonance Imaging Procedure Overview

This procedure group includes magnetic resonance imaging examinations of the pregnant uterus within the female reproductive system. Procedures involve capture and digital reconstruction of multiplanar images using radiofrequency signals in a magnetic field to evaluate the pregnant uterus. Accurate ICD-10-PCS coding identifies the imaging performed and supports correct inpatient reimbursement and clinical documentation.

B	Section	Imaging
U	Body System	Female Reproductive System
3	Operation	Magnetic Resonance Imaging (MRI)
B	Body Part	Pregnant Uterus

When to Use

Use codes from this group when an inpatient undergoes magnetic resonance imaging specifically of the pregnant uterus for diagnostic evaluation or monitoring. These codes apply when the MRI procedure targets the pregnant uterus as the body part documented in the medical record.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
BU3BY0Z	Magnetic Resonance Imaging (MRI) of Pregnant Uterus using Other Contrast, Unenhanced and Enhanced
BU3BYZZ	Magnetic Resonance Imaging (MRI) of Pregnant Uterus using Other Contrast
BU3BZZZ	Magnetic Resonance Imaging (MRI) of Pregnant Uterus

Typical Clinical Scenarios

A pregnant patient at 32 weeks’ gestation is admitted with new-onset focal abdominal pain and concern for placental abruption on ultrasound; inpatient evaluation is needed to assess placental location, fetal well-being, and uterine pathology without ionizing radiation, so MRI of the pregnant uterus is performed to provide detailed multiplanar soft-tissue imaging. Typical codes: BU3BY0Z, BU3BZZZ
A pregnant patient with a known uterine mass identified on prior prenatal imaging is scheduled for inpatient MRI because of progressive symptoms and to better characterize the lesion’s relationship to the pregnancy and adjacent pelvic structures; the study is performed with contrast considerations documented and both unenhanced and enhanced sequences obtained for diagnostic clarity. Typical codes: BU3BY0Z, BU3BYZZ
A pregnant patient presents to labor and delivery with unexplained antepartum hemorrhage and hemodynamic instability requiring inpatient urgent imaging to evaluate suspected uterine dehiscence or placenta accreta spectrum; rapid MRI of the pregnant uterus is obtained to delineate placental invasion and guide obstetric management. Typical codes: BU3BZZZ, BU3BYZZ
