CPT® Code 11104 is used to report a punch biopsy of the skin for a single lesion. This procedure involves using a circular blade tool to obtain a full-thickness skin sample (including epidermis, dermis, and sometimes superficial subcutaneous tissue) for diagnostic evaluation.
Punch biopsies are commonly performed to diagnose dermatologic conditions, inflammatory disorders, and suspicious lesions.
Key Facts About CPT® 11104
- Service type: Minor surgical procedure (biopsy)
- Procedure: Punch biopsy
- Lesion count: Single lesion
- Depth: Full-thickness skin sample
- Setting: Office or outpatient clinic
- Provider type: Physicians and qualified healthcare professionals
Common clinical indications:
- Suspicious skin lesions requiring diagnosis
- Rashes or inflammatory skin conditions
- Pigmented lesions or atypical moles
- Evaluation of possible skin cancer
- Chronic or unexplained dermatologic conditions
When to Use CPT® 11104
CPT 11104 is appropriate when:
- Performing a punch biopsy on a single lesion
- A full-thickness tissue sample is required for histopathologic evaluation
- The procedure is performed for diagnostic purposes
- The lesion is clearly identified and documented
Examples:
- Biopsy of a suspicious mole to rule out melanoma
- Punch biopsy of a chronic rash for diagnostic clarification
- Sampling a lesion suspected to be inflammatory or autoimmune in nature
- Evaluating a non-healing skin lesion
Documentation Requirements
To support CPT 11104 billing, documentation should include:
- Patient identifiers and date of service
- Location and description of the lesion
- Indication for biopsy
- Procedure details (punch technique, size of instrument)
- Number of lesions (single)
- Anesthesia used (if applicable)
- Specimen handling and submission to pathology
- Patient tolerance and post-procedure condition
- Provider signature and credentials
Detailed documentation ensures accurate reporting and supports medical necessity.
Reimbursement and Coding Considerations
- CPT 11104 is generally reimbursed when medically necessary
- Report 11105 for each additional lesion biopsied
- Do not report separately for simple closure, as it is typically included
- Pathology services (e.g., 88305) are billed separately
- May be billed with E/M services if separately identifiable (modifier 25 may apply)
- Cosmetic procedures are typically not covered
Always verify payer-specific dermatologic procedure guidelines.
