CPT® Code 11100

Deleted

1. Indications

The procedure coded as CPT® 11100 is indicated for the biopsy of a single lesion located on the skin, subcutaneous tissue, or mucous membrane. The specific indications for performing this biopsy may include:

• Suspicious Lesion: A lesion that exhibits characteristics suggestive of malignancy or other pathological conditions that require histological evaluation.
• Diagnostic Purposes: To obtain tissue for diagnosis when a lesion presents with atypical features or when there is uncertainty regarding its nature.
• Monitoring Changes: For lesions that have changed in size, shape, or color, necessitating further investigation to rule out any serious conditions.

2. Procedure

The procedure for CPT® 11100 involves several key steps that ensure the effective and safe collection of a tissue sample from the lesion. The steps are as follows:

• Step 1: Preparation of the Site The physician begins by thoroughly cleansing the area surrounding the lesion to eliminate any potential contaminants. This step is crucial for reducing the risk of infection during the biopsy.
• Step 2: Anesthesia Administration Following the cleansing, a local anesthetic is injected into the area around the lesion. This is done to ensure that the patient remains comfortable and pain-free throughout the procedure.
• Step 3: Tissue Removal Using a scalpel, the physician carefully excises the lesion, which may involve removing either a portion or the entire lesion depending on the clinical judgment and the characteristics of the lesion. The excised tissue is then collected for further analysis.
• Step 4: Sample Handling After the tissue has been removed, it is placed in a suitable container and sent to a laboratory for histologic examination. This examination is essential for diagnosing any underlying conditions related to the lesion.
• Step 5: Closure of the Biopsy Site Finally, the physician may choose to close the biopsy site with sutures in a single layer, ensuring proper healing, or may leave it open to granulate naturally, depending on the specific circumstances of the procedure.

3. Post-Procedure

After the biopsy procedure coded as CPT® 11100, the patient may be advised on specific post-procedure care to promote healing and minimize complications. This may include instructions on keeping the biopsy site clean and dry, monitoring for signs of infection such as increased redness, swelling, or discharge, and managing any discomfort with over-the-counter pain relief as needed. The physician may also schedule a follow-up appointment to discuss the results of the histologic examination and any further treatment options if necessary. It is important for patients to adhere to the post-procedure guidelines provided by their healthcare provider to ensure optimal recovery.
