ICD-10-PCS Code For Fallopian Tubes: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BU42 includes procedures performed to image fallopian tube structures in the female reproductive system. These ICD-10-PCS codes are used for inpatient documentation when real-time ultrasonographic imaging of bilateral fallopian tubes is performed to assess anatomy or flow. Accurate coding within the ICD-10-PCS BU42 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Fallopian Tubes Ultrasonography Procedure Overview

This procedure group includes ultrasonographic imaging of the fallopian tubes within the female reproductive system, using high-frequency sound waves to create real-time displays of anatomy and flow information. Procedures involve capturing reflected and attenuated ultrasound signals to visualize bilateral fallopian tube structure and patency. Accurate ICD-10-PCS coding ensures the inpatient record reflects the imaging performed and supports appropriate case mix and payment.

When to Use

Use a code from this group when bilateral fallopian tube ultrasonography is performed during an inpatient encounter to evaluate anatomy or assess tubal patency. These codes apply when the primary action is diagnostic imaging using ultrasound rather than operative intervention.

Typical Clinical Scenarios

A reproductive-age woman is admitted for evaluation of acute lower abdominal pain and suspected pelvic inflammatory disease with concern for tubo-ovarian involvement; clinicians need real-time imaging of both fallopian tubes to assess for dilatation, fluid-filled tubes, or impaired flow that might indicate hydrosalpinx or abscess. An inpatient transvaginal and transabdominal ultrasound focusing on bilateral fallopian tubes is performed to guide management and determine need for urgent intervention. Typical codes: BU42ZZZ
A patient undergoing inpatient workup for infertility after prior ectopic pregnancy is admitted for scheduled diagnostic assessment of tubal patency and anatomy; the team performs ultrasound imaging to visualize both fallopian tubes and evaluate flow or structural abnormalities that could affect fertility. Real-time ultrasonography of the bilateral fallopian tubes is used to document tubal morphology and guide further reproductive planning. Typical codes: BU42ZZZ, BU42YZZ
A postpartum patient presents to inpatient care with persistent fever and suspected retained products and possible tubal involvement; bedside ultrasonography is obtained to evaluate both fallopian tubes for evidence of fluid collections or altered flow suggesting secondary infection or hydrosalpinx complicating the postpartum course. Bilateral fallopian tube ultrasound is performed to inform antibiotic therapy decisions and any need for procedural drainage. Typical codes: BU42ZZZ
