CPT4 code
Name of the Procedure:
Punch Biopsy of Skin (including simple closure, when performed); single lesion
Summary
A punch biopsy of the skin is a minor surgical procedure where a small, round piece of skin is removed using a circular blade. This technique is commonly used to diagnose skin conditions by extracting a tissue sample for analysis. If required, the site may be closed with stitches.
Purpose
A punch biopsy is primarily used to diagnose suspicious skin growths or lesions, including potential skin cancers, rashes, and other dermatological conditions. The procedure aims to provide a tissue sample for microscopic examination to determine the cause of skin abnormalities.
Indications
- Suspicious skin lesions or growths
- Persistent rashes or unidentified skin conditions
- Monitoring of chronic skin diseases The procedure is appropriate for patients with localized skin abnormalities that need further investigation.
Preparation
- Patients should inform the healthcare provider about any medications, allergies, or existing medical conditions.
- No special preparation like fasting is typically required.
- Local anesthesia will be administered, so slight adjustments in medication may be advised by the doctor.
Procedure Description
- The area of the skin to be biopsied is cleaned and marked.
- Local anesthesia is injected to numb the site.
- A circular blade, or punch tool, is used to remove a small core of skin.
- The obtained tissue sample is then sent to a laboratory for examination.
- If necessary, the biopsy site is closed with one or two stitches.
Duration
The procedure typically takes about 15-30 minutes.
Setting
A punch biopsy is usually performed in an outpatient clinic or a dermatology office.
