ICD-10-PCS Code For Ovary Left: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BU44 includes procedures performed to capture real-time images and flow information of ovarian structures in the left ovary. These ICD-10-PCS codes are used for inpatient documentation when diagnostic ultrasonography of the left ovary is performed to evaluate anatomy, masses, cysts, or blood flow. Accurate coding within the ICD-10-PCS BU44 group is essential for proper inpatient reimbursement, as it captures the diagnostic imaging procedure performed and supports clinical documentation accuracy.

Ovary, Left Ultrasonography Procedure Overview

This procedure group includes real-time imaging of the left ovary using high-frequency sound waves to produce images of ovarian anatomy and blood flow. Procedures target the female reproductive system and are performed to visualize structure, assess masses or cysts, and evaluate blood flow. Accurate ICD-10-PCS coding ensures inpatient records reflect the diagnostic imaging performed and supports appropriate reimbursement.

Typical Clinical Scenarios

A premenopausal woman is admitted for acute lower abdominal pain and suspected adnexal torsion after sudden onset unilateral pelvic pain and nausea; inpatient evaluation includes bedside diagnostic imaging to assess ovarian size, echotexture, and blood flow to rule out torsion or hemorrhagic cyst. A real-time transvaginal or transabdominal ultrasonography focused on the left ovary is performed to evaluate for ovarian enlargement, absent or reduced Doppler flow, and complex cysts. Typical codes: BU44ZZZ
A patient with a known left ovarian complex cyst identified on prior outpatient imaging is admitted electively for inpatient observation and further diagnostic workup because of increasing pelvic fullness and concern for malignancy or rapid growth; detailed imaging is done to characterize cyst morphology and vascularity. Inpatient ultrasonography of the left ovary with flow assessment is obtained to guide surgical planning or determine need for intervention. Typical codes: BU44ZZZ, BU44YZZ
A postpartum woman develops fever and worsening pelvic pain with suspected left ovarian abscess or infected cyst after recent pelvic infection; inpatient clinicians obtain targeted imaging to evaluate the left adnexa for fluid collections and perfusion before initiating image-guided drainage or surgical management. Real-time ultrasonography of the left ovary, potentially with contrast enhancement if documented, is used to identify abscess cavity, septations, and vascular involvement. Typical codes: BU44ZZZ, BU44YZZ
