Overview of CPT Code 21073: Radiologic guidance for needle placement in soft tissue

CPT Code 21073 refers to the use of radiologic imaging to guide the placement of a needle into soft tissue for diagnostic or therapeutic purposes. This procedure is commonly utilized in various medical fields, including oncology and pain management, to ensure accurate targeting of lesions or areas of interest.

When CPT Code 21073 is Used?

This code is applicable in several clinical scenarios, including but not limited to:

Biopsy of soft tissue masses to obtain tissue samples for histological examination.
Aspiration of fluid collections such as abscesses or cysts.
Injection of medications, such as corticosteroids, into specific soft tissue areas for pain relief.

Symptoms Indicating This Procedure

Patients may present with various symptoms that necessitate the use of this procedure, including:

Palpable masses or lumps in soft tissue.
Localized pain or discomfort in the affected area.
Swelling or inflammation around a specific site.
Fever or systemic signs indicating possible infection.

Causes and Risk Factors

Several factors can lead to the need for needle placement in soft tissue, including:

Tumors or neoplasms in soft tissue.
Infections leading to abscess formation.
Cysts or fluid-filled sacs.
Trauma resulting in hematomas or localized swelling.

Diagnostic Tests Before Procedure

Prior to the procedure, several diagnostic tests may be performed to guide the intervention:

Ultrasound imaging to visualize the target area.
CT scans for detailed cross-sectional images.
MRI for soft tissue characterization.
Blood tests to assess for infection or other underlying conditions.

Procedure Description

The procedure typically follows these steps:

Patient is positioned appropriately for access to the target area.
Radiologic imaging (ultrasound, CT, or fluoroscopy) is used to locate the target.
Skin is cleansed and anesthetized to minimize discomfort.
A needle is inserted through the skin and guided to the target site using imaging.
Tissue samples are obtained or medications are injected as needed.
The needle is removed, and pressure is applied to the site to minimize bleeding.

Preparation for the Procedure

Patients should follow these preparatory steps:

Inform the physician of any allergies, especially to anesthetics.
Avoid blood thinners or anti-inflammatory medications as directed.
Fast for a specified period if sedation is planned.
Wear loose-fitting clothing for comfort during the procedure.

Recovery and Aftercare

Post-procedure care is essential for optimal recovery:

Rest for the remainder of the day following the procedure.
Monitor the site for signs of infection, such as increased redness or discharge.
Apply ice packs to reduce swelling if necessary.
Follow up with the physician as directed for further evaluation.
