How To Use CPT Code 38531

CPT 38531 describes the biopsy or excision of lymph node(s) in the inguinofemoral region. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 38531?

CPT 38531 is used to describe the biopsy or excision of lymph node(s) in the inguinofemoral region. This code is used when a healthcare provider makes an incision in the skin over the groin and femoral region to access and remove one or more lymph nodes. The procedure may involve the removal of the entire lymph node or only a portion of it.

2. Official Description

The official description of CPT code 38531 is: ‘Biopsy or excision of lymph node(s); open, inguinofemoral node(s).’ This code should be reported with modifier 50 for a bilateral procedure.

3. Procedure

1. The healthcare provider prepares the patient for the procedure, ensuring they are appropriately prepped and anesthetized.
2. The provider makes an incision in the skin over the groin and upper thighs using a scalpel.
3. The provider carefully dissects the tissue overlying the lymph node(s), taking care to preserve critical nerves and structures in the area.
4. The provider removes all or a portion of the selected lymph node(s) and sutures the tissues in layers.
5. If necessary, the provider may place a drain and suture it to the skin to facilitate the drainage of blood or other fluids during the healing process.
6. The provider closes the incision with sutures and sends the excised lymph node(s) to the pathology laboratory for analysis.

4. Qualifying circumstances

CPT 38531 is performed when there is a need to biopsy or excise lymph node(s) in the inguinofemoral region. This procedure is commonly used to identify and diagnose the cause of disease in the lymph nodes or surrounding tissues. It may be performed when there is suspicion of malignancy or infection in the lymph nodes. The code should be reported with modifier 50 for a bilateral procedure.

5. When to use CPT code 38531

CPT code 38531 should be used when a healthcare provider performs a biopsy or excision of lymph node(s) in the inguinofemoral region. It is important to ensure that the procedure is performed in the specified anatomical location and meets the criteria outlined in the code description. This code should not be used for biopsies or excisions of lymph nodes in other areas of the body.

6. Documentation requirements

To support a claim for CPT 38531, the healthcare provider must document the following information:

• Reason for the procedure and the need for biopsy or excision of lymph node(s)
• Details of the procedure, including the incision site and technique used
• Extent of lymph node removal (entire node or portion)
• Use of any additional techniques, such as sentinel node identification
• Any complications or additional procedures performed
• Pathology results, if available

7. Billing guidelines

When billing for CPT 38531, ensure that the procedure meets the criteria outlined in the code description. Modifier 50 should be used to indicate a bilateral procedure. It is important to follow the specific guidelines provided by the payer regarding documentation and billing for this procedure.

9. Examples

1. A healthcare provider performs an open biopsy of inguinofemoral lymph nodes to investigate the cause of enlarged lymph nodes in a patient.
2. A patient with suspected lymphoma undergoes an excisional biopsy of inguinofemoral lymph nodes to obtain tissue for pathological analysis.
3. A healthcare provider performs a sentinel node biopsy in the inguinofemoral region to identify the first lymph node that filters fluids from a diseased area.
4. A patient with a suspected infection in the inguinofemoral lymph nodes undergoes an incisional biopsy to obtain a sample for microbiological analysis.
5. A healthcare provider performs an excisional biopsy of inguinofemoral lymph nodes to remove a suspicious mass and determine its nature.
6. A patient with recurrent melanoma undergoes an excisional biopsy of inguinofemoral lymph nodes to assess the spread of the disease.
7. A healthcare provider performs an open biopsy of inguinofemoral lymph nodes to investigate the cause of persistent swelling and pain in the groin area.
8. A patient with suspected metastatic cancer undergoes an excisional biopsy of inguinofemoral lymph nodes to determine the origin of the cancer.
9. A healthcare provider performs a sentinel node biopsy in the inguinofemoral region to identify the first lymph node that filters fluids from a primary tumor site.
10. A patient with suspected lymphadenopathy undergoes an excisional biopsy of inguinofemoral lymph nodes to obtain a definitive diagnosis.
