ICD-10-PCS Code For Right Knee: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group BQ47 includes procedures performed to visualize anatomical structures in the right knee using ultrasonography. These ICD-10-PCS codes are used for inpatient documentation when real-time ultrasound imaging of the non-axial lower bones is performed to assess joint pathology, soft tissue injury, or fluid collections. Accurate coding within the ICD-10-PCS BQ47 group is essential for proper inpatient reimbursement, as it captures the imaging procedure performed and supports clinical documentation accuracy.

Right Knee Ultrasonography Procedure Overview

This procedure group covers real-time display imaging using high-frequency sound waves targeted at the right knee, a non-axial lower bone structure. Procedures in this group involve capture and interpretation of reflected and attenuated ultrasound signals to visualize soft tissue, joint effusions, and periarticular structures. Accurate ICD-10-PCS coding of these imaging procedures ensures inpatient records reflect the service provided and supports appropriate case mix assignment and reimbursement.

When to Use

Use a code from this group when real-time ultrasound imaging of the right knee is performed during an inpatient encounter to evaluate joint, periarticular soft tissue, or effusion. Codes in this group apply whenever ultrasonography is the operative imaging modality recorded in the inpatient record for the right knee.

ICD-10-PCS Code	Description
BQ47ZZZ	Ultrasonography of Right Knee

Typical Clinical Scenarios

An adult patient is admitted from the emergency department after a fall onto the knee with acute swelling, focal tenderness, and limited range of motion. The inpatient team requests bedside real-time ultrasound to evaluate for joint effusion, hemarthrosis, or acute soft-tissue injury to guide aspiration or further management. Ultrasonography of the right knee is performed to visualize fluid collections and periarticular structures. Typical codes: BQ47ZZZ
A patient scheduled for inpatient evaluation of chronic knee pain and intermittent swelling undergoes diagnostic imaging as part of a planned admission to assess suspected synovitis or degenerative joint disease. Real-time ultrasound of the right knee is used to document effusions, synovial hypertrophy, and tendon pathology to inform the multidisciplinary care plan during the hospital stay. The procedure is performed as a noninvasive diagnostic study prior to therapeutic decisions. Typical codes: BQ47ZZZ
A postoperative inpatient following right knee arthroscopy develops increasing swelling and concern for postoperative hemarthrosis or fluid collection. Bedside ultrasonography of the right knee is obtained to evaluate the joint for localized collections amenable to aspiration and to differentiate postoperative edema from organized hematoma. The real-time imaging guides drainage decisions and monitoring during the inpatient course. Typical codes: BQ47ZZZ
