The Current Procedural Terminology (CPT) code for a punch biopsy is 11104. This code specifically applies to:
- Biopsy of skin, subcutaneous tissue, and/or mucous membrane (including simple closure), unless otherwise listed; single lesion; punch, 3.0 mm or less in diameter.
It’s important to note that if the punch biopsy involves a diameter greater than 3.0 mm, a different code may be required. Additionally, if multiple punch biopsies are performed on the same day, an add-on code (11105) will be needed for each additional lesion biopsied.
Here’s a table summarizing the CPT codes for punch biopsies:
| Diameter | CPT Code | Description |
| ≤ 3.0 mm | 11104 | Biopsy of skin, subcutaneous tissue, and/or mucous membrane (including simple closure), unless otherwise listed; single lesion; punch, 3.0 mm or less in diameter. |
| > 3.0 mm | Varies | Refer to CPT manual for specific code based on diameter. |
| Multiple lesions | 11104 (for first lesion) + 11105 (per additional lesion) | Use the add-on code for each additional lesion biopsied. |
