Overview of CPT Code 10005: Fine Needle Aspiration Biopsy
Fine Needle Aspiration Biopsy (FNAB) is a minimally invasive procedure used to obtain tissue samples from lumps or masses in various organs, primarily for diagnostic purposes.
When CPT Code 10005 is Used?
FNAB is indicated in several clinical scenarios, including:
- Evaluation of thyroid nodules to rule out malignancy.
- Assessment of breast lumps or masses.
- Sampling of lymph nodes in cases of suspected lymphoma or metastasis.
- Investigation of lung nodules or masses.
- Diagnosis of salivary gland lesions.
Symptoms Indicating This Procedure
Patients may report various symptoms that lead to the need for FNAB, including:
- Palpable lumps or masses in the neck, breast, or other areas.
- Unexplained swelling or enlargement of lymph nodes.
- Persistent cough or respiratory symptoms associated with lung masses.
- Changes in voice or swallowing difficulties due to throat or neck masses.
Causes and Risk Factors
Several factors may contribute to the development of conditions warranting FNAB, including:
- Family history of cancer, particularly thyroid or breast cancer.
- Previous radiation exposure to the head or neck.
- Age, with older individuals at higher risk for malignancies.
- Certain genetic syndromes that increase cancer risk.
Diagnostic Tests Before Procedure
Prior to FNAB, several diagnostic tests may be performed to guide the procedure, including:
- Ultrasound imaging to locate the mass and assess its characteristics.
- CT or MRI scans for deeper tissue evaluation.
- Blood tests to check thyroid function in cases of thyroid nodules.
Procedure Description
The FNAB procedure typically involves the following steps:
- Patient is positioned comfortably, and the area of interest is identified using ultrasound.
- Skin is cleaned with antiseptic solution to minimize infection risk.
- A thin, hollow needle is inserted into the mass to collect tissue samples.
- Multiple samples may be taken to ensure adequate tissue for diagnosis.
- The needle is removed, and pressure is applied to the site to control bleeding.
Preparation for the Procedure
Patients should follow these steps to prepare for FNAB:
- Inform the physician of any medications being taken, especially blood thinners.
- Avoid eating or drinking for a few hours before the procedure if sedation is planned.
- Wear loose-fitting clothing for comfort during the procedure.
Recovery and Aftercare
Post-procedure recovery typically involves:
- Resting for a short period after the procedure.
- Applying ice to the biopsy site to reduce swelling.
- Monitoring for any signs of infection or excessive bleeding.
- Resuming normal activities within a day, unless otherwise advised.
Possible Complications
While FNAB is generally safe, potential complications include:
- Bleeding at the biopsy site.
- Infection at the site of needle insertion.
- Injury to surrounding structures, though rare.
- Anxiety or discomfort during the procedure.

Follow-up care is essential for monitoring and reassessment:
- Schedule a follow-up appointment to discuss biopsy results.
- Additional imaging or procedures may be required based on findings.
- Regular monitoring of any existing masses or symptoms.
Alternative Treatments
In some cases, alternative management options may include:
- Observation and regular monitoring of benign masses.
- Medications for symptomatic relief in certain conditions.
- Surgical excision if the mass is large or suspicious.
Home Care Tips
Patients can follow these tips for effective home care:
- Keep the biopsy site clean and dry.
- Avoid strenuous activities for a few days.
- Take over-the-counter pain relievers as needed.
Patient Education & Prevention
Educating patients on prevention and recurrence avoidance includes:
- Regular self-exams for lumps or changes in the body.
- Routine check-ups, especially for those with a family history of cancer.
- Healthy lifestyle choices to reduce cancer risk.
